[Q] How to adjust CPU values for specific apps - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi, was wondering if there is a way or an app to specifically change processing specs whilst using specific apps.
What i would like to do is crank the CPU and GPU to max, as well as fire up all cores when the camera app is active; i believe this would cut some of the shutter lag out and result in snappier performance. also to cut down processing power when camera app is 'minimized'/closed.
Thanks!

You can't. You might be able to find a governor that ramps up faster, but that's probably the best you'll be able to do.

Overclocking

Is there such thing as a safe overclock speed? Will my phone blow up for running it at 1.2 on a daily basis? (I searched for this topic but couldn't find anything specific to the glacier)
Sent from my HTC Glacier using XDA
The cpu in this phone overclocks well. 1.2 definitely won't hurt it. I've known people who ran everyday at 1.5.
I have an excellent cable internet service, with wireless. As such, I don't notice a real difference when I'm on WiFi. I wouldn't want to overclock anymore than 1.2 to 1.4

I'm just referring to the overall speed and performance of the handset. I haven't noticed any better performance with my phone being overclocked...isn't that the purpose of overclocking, to increase speed & performance? If not I am misunderstanding the purpose of overclocking?
I was just saying that with browsing and overall usage on my WiFi connection its hard to notice any changes whether I'm running at 1 GHz or 1.5 GHz ....

Overclocking doesn't speed up internet service though. It just speeds up scrolling through pages, windows, opening applications and overall performance within the applications and device.
I would get SetCPU, then you probably are fine up to 1.4 ghz. I really can't recommend pushing it higher because there isn't a noticable performance increase. I use SetCPU and i am clocked at around 122Mhz-1.3Ghz with a screen off profile of 122-768Mhz and a temperature profile of 32C> 122Mhz-1.0Ghz.
I know, a lot to take in but i get really good battery life with that stuff. If you get SetCPU, experiment.
Also, here are the take away messages.
1. USE SETCPU, ITS AWESOME
2.DON'T PUSH IT TO 2GHZ. YOU WILL FRY YOUR MOTHERBOARD
---If i have help, well you know the button to push---

I have been running at 1.2 for a year now and no problems whatsoever. Actually, what I have found has helped performance was to set the minimum CPU a little higher. It allows for a little less lag while your CPU is "spinning up." (I mean at 230, not at 500 or something)
1.2 is a very stable Overclock. You shouldn't run into any problems with that setting. Anything above 1.5 I wouldn't mess with, and you probably wouldn't see much of a real world speed increase from it anyway.

Overclocking

Someone suggested that I start a thread on the current overclocking situation on the TF300 so here it is!
Yes, the stock kernel supports overclocking to 1.5ghz
*Must be rooted
The best option at this point is the ezoverclock tool that is also being used for the TF201. This app allows you to overclock in a matter of seconds for free.
1. Download and install the .apk
.apk can be found on this page along with DrWowe who created the tool for the TF201 be sure to send him a thanks! http://forum.xda-developers.com/showthread.php?t=1526311
2. Open the app- allow su permissions
3. Make sure the highest setting is set to 1.6ghz. *note, while it says 1.6ghz you will only achieve 1.5, if you set it to 1.5 you will only obtain 1.4ghz. This is due to the fact that the app was build for the TF201 not the TF300)
4.Reboot- Enjoy your now overclocked Transformer Pad!
The AnTuTu overclock master tool has also been tested and confirmed working. Dimply download the app from the play store, open it and allow su permissions. Then set the settings to you liking. However I was getting slightly lower AnTuTu benchmarks while using this method. Probably because the governors are junk (like most overclocking apps).
I am sure there are other methods that are working but these two seem to be the most popular and best available! If you have anything to add feel free to comment or PM me and I will add it to the post. Happy overclocking!
**I take no credit for creating either of these tools, I am simply making it eaiser and more accessable to other TF300 users. I am also not responsible if your tablet blows up while using either of these tools.
Antutu overclock master tool not needed at all. all that's needed is that EzOverclock app. then also the free app from play store called CPU Spy. this is the true way of confirming whether the overclock it really active or not. as it will show whether its active or inactive.
if you want an app to mess around with governors, scale sliders, etc... the app called System Tuner Pro is the best. they have a free version also which works fine. this app is every system tweak app, speed tweaking rolled into one. alot more in depth than setcpu or that Antutu tool. check it out. tons of stuff to play with in there.

Already used CPU soy to confirm the ezoverclock tool as working as well as sticking though .reboots
I'm using antutu cpu master to underclock the device, I have it on max. 1ghz and min. 102mhz. It seems to spend more time in the lower steppings since I made that change (according to cpuspy). I'm still trying it out, to see if it will work for me and save some battery. I also have ezoverclock, I set balanced on 1ghz no need for higher clock since every game I've played runs great.

I have been using ezoverclock with the lowest setting at 1ghz. I seem to be getting much better battery life then stock this way. If I end up needing more power I simply click the performance button that Asus built in. Seems to be working great! It is a great feeling when you are able to under clock and still have plenty of processing power
Does it use more battery at 1.5Ghz? Battery monitor widget shows info.

It is using more battery, although it does not seem to be a huge difference. If you do not need the overclock simply click on balanced mode to save some power. If you are like me and play hard core games on high detail then turn on performance mode when needed.

ezoverclock works best without other OC apps
am using TF-300 Minor tweaks and Speed increase(ROOT REQUIRED) by seanzscreams
@ 1.6GHZ (1.5GHZ)
cf benc : 15064
anTuTu : 12313
my batt almost dead 14 % but dont think it would make much diffence.
can others do some bench to compare please?
i see on anTuTu a TF201 user has 14277 @1.8Ghz
am sure we can go over it? only 967 places to go
Under Asus settings you can enable screenshoys

You can also enable taking them by holding the recent apps soft key in the settings (as the poster before you alluded).

We still don't have custom kernels either... The prime on the other hand does, that makes a large difference. I under clock mine anyway to 1ghz on balance mode, it's smooth and I game at that speed also...

GPU Overclock??

Hey guys, I was wondering if it is possible to overclock the gpu. And if it is, would it really make a noticeable difference?
Sent from my A500 using xda app-developers app
yes its possible, assuming you know what your doing with the kernel. and in my experience, not much. depends on the difference you are looking and what you conciser making a difference, bench scores? game performance? i wouldn't worry about it to much. </opinion>
I like to play games on n64oid. Great app but I feel like my heavily overclocked cpu alone can't handle the more graphically intense games like zelda. I just want to see a little less lag.
Sent from my GT-I9000 using xda app-developers app
I've used a certain rom that had GPU overclock to 400. I noticed no difference. I wouldn't bother IMHO.

[Q] How to deal with lags?

Is there a good way to deal with lags, i.e. to find what exactly causes particular lag and then eliminate it?
If this can be done ,no lags will exist in Android. The question is difficult to answer and is not as easy as you think.

I guess so. But are there no general guidelines? No point to start from? I guess there must be some roughly determined way to identify what causes given lag.
If there would be an algorithm on how to deal with lags, then there would be almost no lags in Android. I do agree with that.
V6 supercharger, Kick ass Kernelizer and other tweaks will help even out lag- but it will always be a problem on any computing system, if this was a quadcore 2ghz phone with mali-t604 gpus in SLI running android 4.2.1 im sure it would be okay
These solutions depend on specific problems. Many things can cause lags

Limiting background processes to 2 and slight over clocking works for me
Sent from my MB526 using xda premium
my understanding is, you are looking for a stepbystep guide what to check to find the cause of a lag.
maybe:
- check memory usage
- check cpu usage (i.e. with os monitor)
- delete/freeze app that has a huge amount of usage...
something like that? i'm no pro, so its just what logic tells me...

[Q] Kernel issues

Hi
First post. Will try not to look the idiot or ask what has already been asked. Here goes, I am unable to find a kernel that actually improves my phone, i currently have the following -
Nexus 4
ROM - PSX V1
Moto x mod (great addition)
Stock kernel
I have tried two or three kernels including the new Trinity one which gave me a worse performance. Would someone point me in the right direction?
Could i also say a big thanks to PSX developer for a great ROM.
Regards.
Have you tried Franco...?
Sent from my Nexus 4 using Tapatalk
did you try adjusting settings to your needs? considering the trinity kernel maxes at 1026mhz by default, until you adjust the cpu speed yourself.
So if I reinstalled trinity and used trickster to increase the cpu, I might get better results?
I haven't tried franco just yet.

Right after a bit of trial and error I reckon I have cracked it.

Improvement is a subjective in this context. In what way? Faster? More features? Better battery life? Better sound quality? Better color? Smoother?
Benchmark means nothing. It is possible to apply the Samsung's dalvik cheat patch to your rom which will increase your benchmark score but yield no real world performance. With some settings you might get great benchmark, but the phone might get hot with poor battery life. Moreover, most benchmark programs do not tell the real story about performance. Antutu and Geekbench doesn't even work correctly with 4.4 and ART. iOS7 might get good scores sunspider javascript, but there are times when Android web performance outright beat it.
This thread falls in the category of "What is the best kernel/rom?" which is against XDA rules so I can;t help you. Research each kernel and read about its features and users feedback and find what is right for you. A lot of time stock kernel will give the best stability and battery life.
I use kernels mainly for features. There are other bigger factors about the operating system that determine battery life and performance.
What I wanted was faster and this certainly is faster. So I'm happy. Thanks for all your help.

Use latest PSX rom, put phone in freezer for 1hour, set CPU to 1800MHZ performance, GPU to 533MHZ performance if possible, raise overall cpu voltage, stop all background app, run benchmark.
