To ROM Developers

First of all, thank you so much for your hard work and your noble strife to improve HTC HD2, a phone in much need of so.
Now to a more seriuos matters, I been testing out ROM´s now (around 15 different ones atm), and i get some striking matches that i want to ask about, all this on my HTC HD2.
Everybody wants to talk of Speed, 576mb, Clocked CPU, HD2 now super fast etc. And my question is the same as to HTC them selfs (boasting all this horsepower and falling so flat), why is menys and scrolling still lagging and showing .... in lack of words, Screen Tearing. Why on earth cant i in phone contacts, or file browsers, start meny, or any darn meny you like, scroll up or down and not feel like the phone is on a bumpy road? Dont know if any of you understand what i talk of, cause i havent seen any talk of it.
In some ways (Like through a non programer like me) it seems like hole darn windows is on some kind of grid, where the menys have to move through tiny bumps to move ahead. Anybody that can shine some light on this.
Im not new to phones, but im no hotshot also. So i want to make sure i made everything correct.
1. Install HSPL
2. Install ROM of liking
3. Hold your thumbs
As you may understand, i have in my own little world pretty humble visions. Fast everyday usage, ither in Windows or in Sense, does not matter. No lagg at all, pure speeeeeeeed. Is this really achivble? I must say im very dissepointed with the HD2´s performance.
Best Regards

I understand what you mean..
Sometimes when flipping from the today in sense to view all 9 programs there is some kind of lag... the start menu also isnt that smooth..

Thats why MS started Windows Phone 7 development from Scratch! Now it will be much more fluid, smoother transistions rather than this messed up piece of code called WM6!

Thats so true...
But I'm still standing here with my 3 months old HD2..
And we have to wait until next month to hear if our devices is going to get the update or not..

My guess would be that they simply purposedly limited scrolling fps to save battery.

But since i must once again give you all programmers cudos, if it was a reduction by Microsoft, wouldnt you all have fixed that already?
Thnx for fast replyes btw. So its basiclly because Windows Mobile 6.5 builds on old programming then?

As you speak of screen tearing, that's also something quite common that you can get on a PC too, mostly noticeable when playing videos or games, and is due to non-synchronisation of screen refresh and image generation. The program creates a new image and sends it to the display buffer while the previous image is being sent to the display. Result is that the first half of the image that ends on the display is the previous frame, and the second half is the new one.
To prevent tearing the technique is to wait until the display finishes showing a full image before sending the new one.
A reason for the "slow" fps could simply be that the screen can't be refreshed faster due to hardware limits, which is totally possible with such a high resolution display.
Personally I don't find it "slow", of course when you put it side by side with an iphone it's definitely slower, but the iphone has a crap resolution... and I definitely prefer the HD2's screen resolution to slightly smoother srolling.

Kilrah, so you mean, basicly, if a better grahic driver could be created it could be solved? I mean do we even have any REAl graphic drivers, exept OpenGL and Chainfires 3d patch that are good, but not enough apperently?

have you toyed with the tweaks in THIS thread?
I have a noticably smoother sense sinse applying them.
Be warned thoughm, some of them will lock up the wrong phone. (I.e watch out for 576 mb tweaks on a non 576mb rom)

Maybe, maybe not. If it's hardware related, no way. Would need to know what the screen refresh frequency is, and anyhigher refresh obviously wouldn't be possible.

In my opinion this cant be the reason. Have you ever scrolled in p.ex. TouchTwit1.6 ? It is 100% (!) fluid. So there is some Software around that shows us that it can be different...

Se limiting fps to 30 max?

I tried to benchmark my sony ericsson xperia x10 with FPS2D...
It seems that it limits the speed to 30FPS MAX... it tries to go higher but it keeps getting blocked at 30fps wtf is wrong>?

They locked it down to 32fps ... Nothing can be done until we can cook custom ROMS or SE decide to unlock the cap. Its just like EVO 4G.

I wonder why they felt they had to limit it? I noticed when doing the GLBenchmark1.1 test that it maxed out at 32fps. The N8 is hitting 60fps, why dont SE just allow it to go above 32fps?
Does anyone know why HTC limited the Evo 4G? Could explain why SE did it to.

HTC removed the 30 fps cap in one of the latest updates, afaik.
Does anyone know if this limit on X10 will be broken with 2.1?
otherwise I'll think I might buy another phone

Why? What difference does it make?

The telephone is much smoother @60fps. dunno if it affects touchscreen responsiveness too (or the way you feel it )
its hard to explain, but if you manage to try an iphone 4 you'll surely notice the difference.

You know, until this thread, I doubt anyone on here even knew/cared about the FPS.
It's nice to see that the Android fanboys haven't disappointed me with their endless pursuit of meaningless higher numbers.

umm... can you explain to me what is meaningless about it? is having more horsepower in a car meaningless? is having a larger house meaningless? is having more money meaningless?
yeah i bet you answered no to all those questions, if not then somethings wrong with you.
these numbers that are limited to something less than what the hardware is capable of is stupid. the pursuit of higher performance on a device that is MORE than capable of it (due to the lack of software to support it atm), is something very viable...
as for the android fanboy comment... thats just stupid lol

Did you honestly notice any performance issues before this thread?
If your eye can really tell the difference between 60 and 30 fps, I applaud you.
My point isn't the fact that it's actually locked (I don't care either way), I just find it funny that as soon as an Android fanboy finds out their numbers are lower than someone else's, they freak out.

Its possible that they decided to cap it after finding stability issues at higher frame rates... even then, how does it actually affect anything? I mean, do videos become visibly smoother at higher frame rates? (I honestly don't know, so I'm asking)
And wrt the android fanboy comment - If you don't find android fanboys at xda, where else would you find them

actually i kinda care, coz one of my games, hyper jump i think has a refresh line split straight down the middle and i can't see scrap my when... etc. etc.
but yea i like things to look smooth, what's the fps on the iphone coz it looks so slick

It doesn't affect videos, because the video would have had to be made at the higher FPS to actually benefit. FPS only benefits games, and the goal is always 30 FPS. Higher is nice, but not needed for most games. I would be surprised if iPhone games ran higher.
Maybe I should've wrote "X10 Fanboys" ahaha. Always wanting that 2.2, 16,000,000, 3.0, 512, ect.

Dunno about videos but the android interface would be sensibly smoother. it's like playing a 3d game. is it more playable at 60 or 30 fps?
I seriosly thinks that the FPS cap limits the touchscreen responsiveness too.

60fps is better only if it doesn't fall from 60 to 20 fps which i think will happen just too often thanks to Adreno 200(while playing 3D games at least)

When playing Asphalt ive noticed skipping/jerking of frames, and im betting thats due to the cap. The Andreno200 seems to be capable of upto 45fps, thats what the Desire is reflecting in the benchmark tests, im sure the extra 13fps will make a significant difference when gaming, i love playing games on my X10's gorgeous 4" display, the phone is so great to hold and play games on, but it sucks when you run into jerkyness here and there due to a dam limit, when the hardware is far more capable.

Um, locking the frame rate results in smoother graphics, not jerky ones.
If you're experiencing jerkiness, then the frame rate never reached the limit when you were using the software. The whole point of locking the frame rate is so things appear smooth at all times.

Part of the desire comes from other Android handsets already having these features eons ago. There's nothing wrong with wanting the best performance from your phone.
I bought mine because it had the best specs at the time and I was assured that updates would soon follow, not minor updates but major ones.
It seems in all your posts you do nothing but defend the X10 and shoot down everyone who isn't 100% satisfied like you are. I admit that I've been negative in the past but I've forked out more than half a grand for a damn phone, and yes, I did do the research. I thought SE would have killed the Android market with the way they fluffed up their phone and boasted in all their marketing pieces.

why don't you think it the other way around, maybe SE has limited the FPS to save you from a crashing OS, it's a common knowledge that X10 is one of the highest specs phones in the market till today, and it's a common knowledge also that SE has modified the Android 1.6 too much to be able to work on that specs, and in their process to do so they admittedly limited the functionality of the phone maybe to keep the OS working smooth without any flaws till they issue the long delayed Android 2.1 update.

Its a common fallacy, people assume that bigger numbers mean better. That is only true if there is a noticeable difference...
A bigger house is of no use to you if all the extra rooms are locked.
... and there is no extra "cost" or detrimental effect...
A bigger house is great, if it doesn't mean it suddenly costs you more than you can afford.
To address those points, it is generally accepted that the human eye cannot resolve movement at much higher framerates than 28-32 FPS. Any film you have seen at the cinema, and any TV you have watched has been at 24FPS and that certainly has never seemed jerky to me.
So is 60 FPS better? Well no not really, as you cant see the difference. And whilst you may be able to argue you can see the difference between 25 and 35FPS (Note 30FPS sits in the middle ) If you make the claim you can differentiate all the way up to 60, im going to need serious proof.
Its worth noting at this point that a lot of hoohah is often made about framerates, especially in 3d gaming. This is NOT because of the user experience, its because its a good way to compare hardware performance. Past a certain point (around 30fps) it makes little to no difference to the user experience.
Now onto the second part of my awesome house analogy, why bother locking it anyway? Because to produce MORE than 30 FPS, i.e. to go beyond the boundry at which the user can tell a difference, requires more power.
More power means poorer battery performance, amongst other things (although in mobile device design power consumption is a chief concern). The key point here being that it requires extra juice but delivers no increase in user experience. Essentially just chucking power out of the window, to nobodies benefit.
Finally, those people experiencing "lags" in games, that's not due to frame capping. That happens when the frame rate drops BELOW the cap (considerably below) therefore the cap has had no effect.
Finally, a disclaimer, im not blindly defending SE here, i think their software and post sales support leaves a LOT to be desired, but lets ***** and flame about something that deserves it:
Books are for people too poor to buy a TV. Discuss.

More like I hate stupidity, and most of my posts are defending intelligence. I'm convinced that 75% of this board are high school students living with their parents in their basements, buying phone's with daddy's credit card.
Anyway, the poster above me explained it perfectly.

[Q] Lower resolution to 1920x1200

The main complains I read about for the Nexus 10 stem from the extra high res display.
Would it possible... or dangerous... to have the option to lower the resolution when you do not need it so high?
1920x1200 would maintain the 16:10 ratio and still have a high res, but battery life and overall speed would surely improve greatly.
Anyone know of any reason I should not experiment with this?

Does it even work that way? You're still pushing a resolution of 2560x1600 regardless.

Actually just found this:
LCDDensity for Root
Does this work with N10?

Not sure how it would be dangerous to lower the res but wouldn't the picture quality degrade if you do this?
If you do this on a regular pc lcd monitor, everything looks like a turd.

That's just for changing the PPI. Something like how PA works. You'll just end up getting a smaller or larger version of the app.
There's nothing wrong with the resolution. Overall speed is top notch and battery life is pretty good. Most of the complaints are because of Chrome. Chrome itself is the problem though.
Don't worry dude.

To my knowledge, you can't directly modify what resolution the device runs at easily. You can change screen DPI easily, but not resolution (most, if not all apps only change DPI).
For example, changing the N10 DPI from 320 to 400 will make the UI look bigger, but games and everything else will still be running at native resolution, so essentially no performance change.
I imagine editing the resolution directly would require some source-code modification on either a ROM or Kernel level, or maybe even LCD driver, but I have no idea.
In any case, the N10 is fine at the resolution it's at, but a few non-optimized apps may not run ideally. I would say the CPU architecture is more to blame though instead of the screen resolution.

I don't know how bad it would look.... it is a small screen so would think it would not be as bad as on a 22+ monitor.
I am still waiting on my N10 so can't try it yet.

This is definitely true for games. Graphics intensive 3d games, like Shadowgun Deadzone, have a hard time running at native resolution on the Nexus 10. The game renders at native resolution even on the lowest graphics settings. Most maps are playable, but some have a really hard time. On an LCD display, the only way to scale back resolution, and still look reasonable, is to run at 1/2 resolution (4 pixels get rendered as 1). When the iPad 3 came out, many devs chose to continue rendering their games at 1024x768 to keep performance acceptable.
What would really help, is a way to fool a 3d game into rendering at 1/2 resolution. Playing at 1280x800 would still look great, especially if 4x MSAA was enabled.

If a game does not run well it is because the game is coded terribly, not because the resolution is too high. If we were able to lower the res it would help performance, but that is just a band-aid on the real issue of the developer not doing a good job with whatever they made. The GPU is running at its max potential, but it has enough power and bandwidth at stock speed that it can render any game that is properly made at 30fps.

DEAD TRIGGER has an option in a config file for screen resolution. I might imagine editing this file would tell the game to render at a lower resolution, but I'm not entirely sure. In any case, not entirely sure if any other game would have such a config file or resolution setting either.
GTA III has an option for screen resolution conveniently in it's in-game options. Setting it at 100% does cause a noticeable drop in FPS. Setting it to about 50% allows for (imo) playable, high FPS, without too much of a drop in overall quality. Pretty sure GTA III is just not "as optimized" as it can be though.

I respectfully disagree. Running the original Doom, or Crysis, at 2560x1600 are two dramatically different things. Does that make Crysis terribly coded if it doesn't run well on your hardware at that resolution? For pure aesthetics, I'll take a playable Crysis at 1280x800 over Doom at 2560x1600. I suppose using Doom in that example was not so appropriate given that it was programmed by God himself.
Given the tiny fraction of the mobile market that 2560x1600 makes up, I think it's pretty unlikely that we'll see games optimized for that resolution. Adding a 1/2 res setting for games seems like a far easier solution.

I know that two games can have very different loads on the system, but if you look at all the tech doc's for the device the Mali 604 graphics processor has enough power and bandwidth to just barely push 30 fps @ 2560x1600 with properly coded apps. So if something is not coded well, it will not be able to reach proper frames per second to run smooth on this device. Optimizing for a resolution and have optimized code are very different things.

Poor Performance of Xperia Z

Hi All,
So I'm going to speak about my Story in Smartphone and all my disappointments about the Sony Xperia Z. I was a Iphone User since the first one. I bought the Iphone 1 , 3G , 4 , 4S and my last one the 5. After reading a lot about Android, I decided to change and find a good phone on Android. So at this time XZ was the best with Quad Core Processor and 2 Go of Ram. I was sure that the phone will be incredibly fast! I bought a Galaxy Tab 2 before and even with Cynogen Mod it was horrible!!
So I bought my xperia Z, I was very Happy about Android, lot a personalization, beautiful etc until I see the real performance of the device....
I had a Micro-lag each time I'm scrolling between desktop with the base launcher xperia... Impossible I tought.. and no really it was micro-lag... So I decided to try Nova launcher and now hoo a little better but each time after unlocking the phone a microlag appear again when scrolling..
So After try a lot of launcher and same problem on each launcher except one! TSF Shell was the only fluid launcher... And it's the one with the 3D animations.. Weird....
So I was a little more happy but after that I decided to check performance in games.. So I install Real Racing 3 and hoo working fine but no fast as my Ipad Mini who are supposed to more 2x less powerfull... and the graphic was better too on ipad mini.. and the FPS was not good at all.
Then I tried Asphalt 7 Heat , and same problems... not perfectly fluid , I'm sure I have max 40FPS..... and the graphics are far from the quality of my ipad..
When I play 10 min the phone beginning to heat heat heat until 42 ° ... The Heat control service launch his process and powerdown the CPU... Great!!!
So I like Android.. It's a great OS , I liked it. I didn't want to change but those points disappoint me a lot... Why the base launcher is not running well? I don't even see the difference of performance between the old Galaxy Tab 2 and the XZ... and then why it's the most ressources launcher who are the most fluid one?
The Last thing is the MediaServer, it's running all the time and feed with half of my battery and I don't even know why... probably indexing media but it's everyday and when I check the CPU during the running of this process it's even more than 10% so why the battery is used so much?
Thanks a lot all for your help and excuse my poor bad english

You can deactivate certain applications like your app that are running medias.
And if you decide if a phone is good or not only for homescreen lag (iOS even hasn't one) or heat performance playing games why did you choose Android?
Oh and i'm sorry for the heat control service that powerdowns your cpu saving it.

If you read everything I didn't juge android cause of that. I put a lot of Argument.
And then so you tell me that Scrolling between desktop is laggy on all android devices? and u said also that all android device heat? That's wierd

Ah, yet another repetitive thread that should have been in the troubleshooting section with all the other same threads.
Sent from my gorgeous White Xperia Z

Nope, just sony having problems with no smooth launchers (every xperia i had)
Sent from my LT26i

Sad to hear that you are experiencing poor problems with your device.
But first and foremost, do not compare the performance in gaming with the Idevices, because the way the games are made is often very different per platform. A lot of these games are made with idevice in mind, so the developers have put a lot of emphasis on the develophment there, so comparing framerates and else is like comparing apples and oranges.... We know that don't work that well.
Regarding the heat; in my ecperience every processor gets warm after intensive usage, and gaming is intensive. So yeah, a processor can become a hothead in that situation. Is like playing Far Cry 3 on Hires on a PC, and not expecting the GPU to run a bit hot....Kind of makes sense....
I have the same phone. And yes it is not perfect, but no phone is. Luckily I do not have any issues, but I guess the issues that people are experiencing now, might or will be resolved with the hopefully coming firmware.
I'm not a fan of any brand, I just get allergic reactions fro idevices. If for some reason you are not happy with the phone, return it and get another before it is too late to do that. And get another one. I mean brand. Or stay with your iphone 5.:laugh:

Sad to hear that you are experiencing poor problems with your device.
But first and foremost, do not compare the performance in gaming with the Idevices, because the way the games are made is often very different per platform. A lot of these games are made with idevice in mind, so the developers have put a lot of emphasis on the develophment there, so comparing framerates and else is like comparing apples and oranges.... We know that don't work that well.

No like I said , I choose this one cause I wanted to switch to android Iphone is good but too lock.. The problem is that I don't have any heating with the Iphone 5 even playing game. Here with the sony, it heat so much that I don't even be able to touch it..
I really hope an update will come to solve all this

Every Quadcore phone is heating up a lot during playing games. That's not a Sony issue

Don't forget that the iPhone only has 1136x640 pixels vs 1920x1080 of the XZ, plus not all applications/games are optimized for fullhd.

This Linux version is known for this, the next version in JB 4.2.2 is much smoother and designed for higher specked devices. As Renzo4000 points out 1080p is new and nothing is ready for this properly yet, only been out for about 3 months on any phone, so obviously nothing has been optimised for that. And most stupid games etc just scale to fit the screen because they are not made for that resolution, I am sure you know if you enlarge photo's or anything beyond 100% it pixelises etc
Secondly once you unlock the boot loader and install optimised Roms the system will fly.

this one...
sony is first fullhd android device... even tabs were 1280x720..
so software has to be optmized, for example, i have a strategic game (majesty) wich has serious problems in menu (everything becomes unstable) and game interface is too small...
or i tried another game (don't remember wich one) wich started in a window with black borders...
same goes for microlags, new kernel is much more optimized for s4 architecture , so we have to wait a couple of weeks... a friend of mine with nexus 4 had changes equal to day/night going to 4.2.2 even battery performance was much better
you can even block some apps (for example if you have a branded phone, you can have some bloatware)

Ok So the problem is really the old version 4.1.2 so I need to wait for the 4.2.2 or Flash with Cynogen ROM FXperia but losing my warranty Can't wait for this update So after this update the system will fly I suppose Yeaaah because , I like Android, I like the XZ , it's the only problem

XZ runs now on 4.1.2 and 3.4 kernel. The 4.2.2 update should also bring a new kernel, 3.6. sony XZ will be the first phone with 3.6 kernel.
4.2.2 together with the 3.6 kernel is way better optimised for the hardware etc in the XZ. 1080p is quite new so nothing is optimized yet, like posted before
Also, I don't have lag in Sony launvher, removed the weather widget, added some tweaks and all is really smooth now

Tips to improve Z1 functionalists (Battery, Camera, Speaker, Performance ...etc)

I see people are complaining about the same things, and every now and then a new topic is opened with similar questions and concerns. Therefore, I thought I would make this topic where anyone has question or concern could come and get advice such as better way to get nigh shots or how to improve battery life ...etc. Some of the ideas in this topic will be from me and some others would be referring to other topics in this form so it gets easier for new owners to find answers to their questions and concerns and it will make the forum cleaner from the repetition. This will be quite a lot of work which would take couple of days so please be patient while I am working on it.
If you have any ideas, suggestions, things to add, remove or modify, please let me know. everything in here isn't mine, its from everyone in this forum.
I won't mention names because I don't want to forget anyone and because I don't remember from where I got some information but thanks for everyone contributed and if you need your name in, please PM me.

Battery
You need to understand few things to squeeze the most out of your battery. the basic answer is to monitor your battery and avoid things that drain your battery. so what uses more battery, I will put list of things that use the most battery in order (what use the most to the least). The list came from me monitoring every single one alone (it might not be accurate though)
1- Processor
2- screen
now people would say that screen uses more than processor. In order to test this, charge your phone to 100% unplug it and directly play heavy HD game for 30-60 min and go and check battery stats, you will see the game no.1 then screen no.2. the problem with the processor is that when it heats up, it wastes ALOT of battery as the heat is just energy came from the battery. if you want to extend you battery life, you should start with these two as they use more battery than everything else. To make it simpler I would say 1 hour of screen on uses battery enough to keep your wifi on for >1day (and I mean wifi not the whole phone with wifi on)
Recommendations:
a- Avoid using apps/games that heat your phone (most games does, but try to avoid when possible)
b- Avoid using your phone while hot (this will degrade the battery and the screen and will hurt other internals such as processor in the long run and will also waste too much battery)
c- If you are a heavy gamer you might need to underclock your processor (to protect your phone from heat and extend battery life), I would say 1.5-1.7Ghz is good. Here is topic about underclocking
http://forum.xda-developers.com/showthread.php?t=2467743&highlight=tips
d- Reduce the brightness will save you good few hours of use
3- auto sync
4- 3G/4G
5- wifi
6- GPS
I put auto sync first because in order to have working auto sync, you will need wifi or data + processor to process what are you syncing
GPS actually consume more battery than wifi when both are working, but the good thing about GPS is that if it is not in use even if it is on, it doesn't use battery unless it was needed to locate the phone.
Recommendation
Turn them off when not needed. There are certain apps in the play store that turn off wifi, data and auto sync when screen off then turn them back on when screen is turned on. I use tasker which does this and check for downloads before turning off wifi or data.
Additional recommendations
Uninstall/disable apps that you don't use, especially the ones that are running in the background but don't overuse this and disable everything because you are better off having an old nokia that will last longer than any smartphone currently available.
here is topic about disabling apps
http://forum.xda-developers.com/showthread.php?t=2510774
And unistaling them
http://forum.xda-developers.com/showthread.php?t=2520764

Performance
Although I don't have any issue with regard to the performance of my Z1. But here are couple of suggestions to improve the performance even further.
1- Disable/Uninstall apps not in use and working in the background (more details in previous post about Battery)
2- Use various Karnels or ROMs available (you need to be rooted or have unlocked bootloader, I am not responsible about anything)
3- One guy suggested the use of Seeder.apk which was useful (I haven't tried it though, but if you want to, go ahead), here is the link
http://forum.xda-developers.com/showthread.php?t=2507537

Camera
Before going into more details on how to get better shots, you need to know that the camera in the Z1 is like Pro camera compared to some other smartphones where the camera is more like point and shoot camera. What I mean by this is that the Z1 provides lots of setting which you can play with to get better shots. There is auto mode but it doesn't give the best results, just like pro camera, all professional users use manual modes to get the best shots and they change the settings according to the picture they want to take. This is the case with the Z1, you need to know few things and play with the settings to know how to get the best results. What I will provide here is just a guideline that isn't necessarily going to give the best results everytime and certainly not to for every taste.
Things you need to consider
in most cases:
1- 8mp images are better than 20mp images.
2- 4:3 gives better results than 16:9 because it uses the whole sensor.
3- Manual gives better results than iAuto even though all other settings were auto.
4- The new .257 gives better results the previous versions
5- Turning on HDR or Timeshift burst improve the images sometimes
Good lightening situations
you probably don't need to play much with the settings if you are capturing images in good lights.
However, few people suggested few things that can improve the images including:
1- Lower the ISO between 50-200 (this will reduce the shutter speed which is not good if you have shaky hands or you are capturing moving objects)
2- lower EV which have similar effect to lowering ISO but without lowering the shutter speed (which I found a better choice)
Poor lightning conditions
Here is the difficulty were you might need to change the settings from image to image and need to test different suggestions to find the best shots. Auto mode doesn't work great here either. Few people suggested few things such as
1- lowering the ISO to 50-200 and slightly increasing the EV (it does reduce the noise but increase the chance of blurry images and reduce the brightness of the images as well)
2- I suggest using "Night Portrait" scene without modifying any other settings (it gives good images with minimum noise without making the images dark or blurry)
Using Other apps
Some people suggested using other apps and they gave better results but I didn't use any. here is the link.
http://forum.xda-developers.com/showpost.php?p=47321605&postcount=13
At the end, here is a link to a website of one of the developers who gave few suggestion for better images
http://xperia-dev.be/wp/xperia-z1-camera-tips/

Speaker
Again, the speaker of the Z1 comes with lots of settings, so you might need to play with them to find what suits you. But you need to remember that different songs might sound better with different settings.
ClearAudio+ is like auto mode with the camera. It tries to find the best settings for each song. It is good at doing so but you can get better results (louder and of better quality) if you manually adjusted it.
first you need to untick ClearAudio+ to be able to go to sound enhancements. Tick Dynamic normalizer. then click on settings and tick Clear Stereo, Clear phase and XLoud and set surround sound to Studio. then go to the Equaliser. here you can adjust the settings to your taste. However, if you don't have special preferences, you can move all sliders to +10 to get even louder sound from the speaker (it does make difference).
By following these simple steps, I got louder speaker than Nexus 5 and SGS4, even in this sealed phone.

It is not the +10 equalizer. but having everything on the highest with already high volume song will probably have an effect. I usually have the equalizer at +10 but then reduce the volume if the song was so high (easy to do it with the volume buttons rather than changing the equalizer every so often). But then there are MODs that increase the volume of the speaker where you can do this with ease

Why should you have to avoid using certain apps on your smartphone if it heats up, surely this indicates a fault? A brand new phone shouldn't heat up til its unusable...

Faulty units needs to be returned for sure. I am talking about good units but faulty apps (which you need to avoid). There are apps and games that heat the phone unnecessarily (which are poorly built) those are the one you need to avoid especially if there are better built ones that does the same thing without heating the phone.
I use heat as an indication of how well an app is built (this isn't necessarily accurate) but if you find an app that does very little yet heats the phone quickly, then you either have faulty unit or the app is poorly built and if there is replacement app that does the same job without heating the phone, then you need to avoid using the first app (that what I meant by trying to avoid apps that heat the phone if you can)

Then what's the point of buying a device with such a strong CPU? I'm planning to play GTA Vice City, Real Racing 3, PSone games with emulator, NFS Most Wanted and al those games a lot. A non-faulty unit should be able to perform with 100% CPU load even on longer periods without any effects (damage of comnponents, or ungluing of the glass). And for battery when gaming, don't worry, I have a whole set of portable batteries to keep my phone alive And about damaging the speaker; if the equalizer is here by default (stock), without any mods, it shouldn't affect the speaker. It's Sony's job to protect the speaker, not ours as customers! What I'm trying to say is that everything that comes with the phone we should be able to use at maximum without any damage (so 100% volume, +10 eq, 100% CPU load or the heaviest games on long periods). If anything of stated causes some damage to the unit, it should be treated as a faulty unit.

While I partially agree with your argument, I mostly disagree. for the first part, I am not saying do not play certain game or use specific app, I am giving an advice to extend your battery life. if you found replacement app that do not heat the phone, go with it and if you didn't or just want to keep using the first app, then use it (simple as that).
for the second part regarding the speaker and CPU. I totally disagree with you. Try playing heavy game which heats the phone quickly for long time and keep it plugged in the charger (lets say 10 hours), it will just explode in you hand. Another example, imagine you have a car and you keep harsh accelerating and braking all the time (while according to your sense, you are not doing anything wrong as long as the manufacturer allowed it) this will damage the engine, tires, brakes ...etc and you will pay to repair or replace these things. The same goes for the speaker and CPU, if you overuse them, they will die sooner and you will pay the expense of repairing or replacing them. This goes probably for every electrical equipment, pushing them to their limit, even if the manufacturer allowed this, will make them break more quickly.

Cars are one thing and phones another. Car manufacturers can limit RPM and protect the car on that way. If you limit the RPM, then the driver can keep pushing the accelerator as long as he wants, this wont damage the car. But, limiting RPM's would result in some dangerous situations; imagine you're passing a vehicle and another vehicle appears in front of you. You will need some reserve power to finish your passing before you crash into that vehicle. So limiting RPM would be dangerous. On the other side, limiting your phone's speaker loudness will protect the speaker but it won't affect it's usage. So I believe that speakers are protected to not get overpowered. The amplifier is probably the same power as the speaker itself. But if you root your device and remove that protection or if you even push it more by applying stronger signal, you can damage it. The same is probably with processor. It's clock is limited to a value that can't damage it even on longer usage. But if you overclock it, then you can damage it. I believe and assume that it's like that. At least it should be like that.
I'll keep pushing my volume to the boundaries and playing games as long as I want. If the phone dies, I'll take it to the warranty. There's no proof that I modified the phone on any way so I must get a new one or a free repair. And believe me, I pushed my X10 way more than I should in terms of everything. I used boosters for volume on my rooted device and sometimes I even heard the speaker making strange sounds like it will explode But nothing happened. I even tweaked the LED flash for getting double stronger torch. There was a warning for damage but on shorter periods it worked.
And for the speaker, if you hear the speaker distorting the sound or producing strange sounds, just lower your volume. On that way you won't damage it.

That was my point exactly.
I never said you HAVE to lower your volume always. Actually my post was about giving advice on how to increase the loudness of the speakers. The same goes for the Chip, I tried to give advice on how to improve the phones performance and battery life (which would benefit your gaming experience) But I never said not to play games (I personally play quite often).

Tried that and ended up with a slightly higher volume but poorer quality, clear audio+ ensures best quality but the volume is hampered I guess by the hardware.
