Change Display Resolution - Save Battery Life? - ZTE Axon 7 Questions & Answers

Hello, has someone already tried the display resolution down to spare the battery?
I have tried with this guide, after that the softkeys under LineageOS unfortunately no longer work.
Https://forum.xda-developers.com/moto-x-style/general/increase-battery-life-lowering-screen-t3190234

Oh God, YES! I'd absolutely love for there to be a resolution slider in LineageOS, similar to what Samsung does in Samsung Experience. I'll try to suggest it to the devs as soon as I get the chance.

[Q] Display modes - which to use?

Hi all!
I am wondering which display mode delivers the best experience.. basic or adaptive or something else.
I don't mind the 'punchy' AMOLED screen. I have read many reviews saying the modes have gotten better with Tab S..
Could the people with note 4 try out which mode actually suits all the daily needs like gaming, videos and browsing the best ( I don't want to change modes based on what I'm doing again and again. Just want it to be a single time setup for optimal experience). I will leave the tweaking to when custom roms are available. Not on touchwiz
PS: Screenshots with different modes can help people in their discussion here..
Can't wait for my note. This wait is killing me. Oh well another 4-5 days
On Tab S 8.4 i am using adaptive, it's the best because it changes the colors and everything else based on what you are doing/viewing.
??? Why can't you just try it when you get it?

Screenshots won't provide people with the colour accuracy since the modes are software filters. Basic mode will look the same as video mode in a screen shot.

Yes, it does a great job. But Adaptive Mode only supports on Samsung's stock apps, not for 3rd party apps. So, for myself, I use Photo Mode (a bit brighter) or juz Basic Mode (looks original and soft).

Only 4-5 days, u can try it when u get the phone since our opinions and perspectives may not same as u do. :good:
Thanks
Thanks guys. and about trying myself.. that I shall. Just wanted to get a head start... I have all Samsungs yet none of my devices is amoled. That's why I thought about asking for the general perception

DPI/Resolution Changer Program NO ROOT NEEDED

I got tired of messing around with DPI/Resolution combinations by typing the adb commands every time. So I wrote a nice little batch file that should work for any phone running 4.3 or greater. It doesn't require installation of the android SDK or even ADB - all files necessary are contained in the 7z file. Just run the file and follow the prompts - everything is taken care of for you, including finding the default values for your device in case you mess things up. The program also fetches your current DPI and resolution so you don't have to go digging for it in build.prop or dumpsys to see where you are presently.
Download here goo.gl/YTsHQp
I used to run unrooted on my Verizon GN4 N910V. A resolution at 1080x1920 with 360 DPI forces *some* apps to run in tablet mode, and gives a very large increase in screen real estate. I can live with the small dialer problems (can't be fixed without rooting/xposed as far as I know) and change my launcher, in exchange for a cooler running phone (average 7 degrees cooler under benchmark load) that uses slightly less power (average +27 minutes per charge according to Gsam), scores an increase of 16% in AnTuTu (52077 at 1080p and 45085 at 1440p), and has WAY more screen real estate. I don't notice the difference in resolution at all, even if I'm trying to.
Note that turning animation scale to a value greater than zero may be required for running some launchers nicely while screen scaling is turned on.
The included HOWTO file gives instructions and outlines some acceptable whole number 9:16 ratios and DPI settings for stock DPI ratios - and outlines how to calculate the numbers yourself. Open source on the code, modify, redistribute, etc - just give attribution to zediiiii.
I'm not sure i understand how this improves performance when you are scaling down the objects on the screen.
How can I change the DPI/Resolution per application?

You can't without root.
This program works well. I have noticed some issues when running at 1080p using the DPI provided in the readme. Certain things (boots screen, movies in games) won't play because, I'm assuming, it is relying on the build.prop but the resolution defined in that file is not accurate. It's a minor inconvenience in light of the fact that running at 1080p and with a heavy deploy it getting me nearly 7 hours sot on lollipop.
Nice job @zediiiii.
I tried it on a Galaxy S4 with KitKat and a Galaxy Note 4 with Lolipop. On both devices I just tried to lower the resolution while keeping the stock DPI to resolution ratio, the goal being to save some battery. On the GS4 it definitely reduced heat while playing games and increased the Antutu score. Unfortunately it also broke the stock keyboard and camera. I didn't see any problems with 3rd party apps. On the Note 4 I didn't test as much, but the stock keyboard was also broken.

My understanding is that driving less pixels per square inch (PPI - I incorrectly used DPI in my program...) means less bandwidth through the graphics processor and thus more headroom. So you either slightly increase performance or slightly save on power - depending on how you use your phone.
I use it for the slight power save, because I can't tell the difference between 500 PPI and 300 PPI, and so I can trick apps into thinking I'm using a tablet on my GN4.

When you say broke the stock keyboard, you mean that it's scaled incorrectly and far too big on your screen? How did the other stock apps fair? In my experience, if you stick with the correct resolution to PPI (DPI is the wrong acronym; I was kindly corrected by a fellow programmer) ratio, the stock apps continue to work as expected. Stock apps crash for me when the ratio is lower than it was before, and simply get smaller on the screen when the ratio is higher than before. If stock apps are crashing, you could try incrementally raising or lowering your DPI and checking for results. I made the program so that this was easy to do incrementally for this very reason.

Yes, exactly, sorry I wasn't more clear. On the GS4 i tried multiple resolution and DPI combos, always keeping the stock ratio. The stock keyboard didn't scale properly with anything other than the default settings. On the Note 4 I only tested with 1080x1920 and 480 dpi, and saw the same scaling issue with the stock keyboard. This is not the fault of the script, so it's not a complaint. It's just a note to warn others that if you want to tweak these settings on a Samsung phone, then you may need to use a 3rd party keyboard.
On the GS4, some of the control buttons were missing in the stock camera app, but the Note 4 didn't have that issue. I didn't see any crashing on either device, perhaps because I was always keeping the stock ratio.
Thanks for the good information. My guess is that anything touched by Samsung, eg, the dialer, the home screen, the camera etc will not scale correctly and may be buggy even with the sam PPI:RES ratio. Oh how I miss Xposed (which I think @locolbd knows is the best way to change ppi per app if you have root, among other things)... Not hopeful for a real root solution for VZW GN4 at this point.
not sure if i'm going blind where where is the script located or was it taken out?

Some people have troubles running the first line of the code in the bat file
Code:

If so, you can change it to

I haven't really figured out why this is the case yet. Mine worked until recently. If anyone has some insight I would be grateful. Windows powershell change perhaps?
my swiftkey keyboard became huge after doing this.. Any fix for it?
Thank you for this!
Worked great on my Galaxy S7 edge!

Because I mentioned my lack of hope for root on the N910V earlier - if anyone hasn't noticed, there is a great guide for permanent root (start here, it links everything for 6.0.1 upgrade) on the N910V Verizon Galaxy Note 4. I'm running 6.0.1 on Jasmine Rom 7 with all the rooted trimmings and no serious issues to date.

[G935F] ROM, kernel, ultra-noob questions

Hello droidsmiths,
S7 Edge is my first ever smartphone (yep, late to the party). I was looking forward to trying new ROMs and kernels, to get more customisation and have proper (admin) control of my device.
First I tried RR, whose customisations are excellent, but averaged ≈3 hours "normal"-use battery life (stock @ ≈8 hours). AOD/USB stopped working, and the phone was always warm to the touch, even in standby. Is that normal?
I then tried Helios, then SuperMan (and their respective kernels) but I can't find anything different. The included apps/fonts are handy though. All Settings customisations/options seem identical to stock except a new icon here and there, is that correct?
I would like to customise appearance / UI settings (e.g. no animation, white-on-black as default) and have CPU/GPU/RAM/network control. Ideally, battery life at maybe >75% of stock. My expectations might be too high, sorry about that, I am new to all this. I'm a Windows developer, so not too bad with those OSes but totally lost in Android. (Can't even find a way to set the wallpaper to be just black, yikes!)
Is there a TW-based ROM that allows in-depth customisation like RR, or a non-TW ROM with working AOD and fingerprint scanner?
Thanks for any advice/help you can provide, and to the developers for their work.

Welcome to the world of android!
Big advocater for touchwiz ROMs here. Never understood AOSP based ROMs like RR on Samsung phone - nothing improved really (worse battery life, camera, lost features, mild if any performance gain) + I reckon you bought the wrong phone for yourself if you use AOSP ROM on a samsung. Just my opinion though.
Theming - Superman has quite a few things you can change in the superman settings app. most notably for me notification appearance and blur effect on notification pulldown. If you simply want to change appearance, you can use samsung themes. There are plenty of black and white themes there. If it's still not enough, you can use Nova Launcher?
Kernel control - use superkernel with the ROM if you like to tweak. synapse is buggy but will let you tweak heaps. Kernel adiutor has less tweaking ,but more stable.
Performance, battery life - I'm on superman ROM with Superstock Kernel, better battery life than stock for sure. 2% drain overnight (6-8 hrs), ~12-20% drain in 24hr on an average day for me, pretty much default superstock kernel settings (changed IO scheduler and TCP algorithm). Greenify / forcedoze helps with battery too. Performance is pretty much the same as stock in my experience.
Havent tried helios, but I believe it comes with Xposed which offers heaps of customisation. Kernel is pretty much stock here I believe, but you can flash a kernel over it. For tweaking use Superkernel, Notorious or TGP kernel. You can still theme store here too.
I hope this helps. Any questions, let us know

I'm coming to the same conclusion (wrong phone), unfortunately. Wish I knew beforehand about Samsung locking things down so hard before I purchased; was never mentioned in reviews though. It's only been a couple of days and I still have accessories being shipped, so won't sell it just yet. In the meantime I'll see if I can tailor it to be workable.
TBH any ROM is fine, so long as I can do two main things: default to black background/white text (e.g. my Win 10 laptop), and CPU/GPU control. White-on-black is more important, I have a mild optical disorder. The colour-inversion accessibility option is excellent, but as it applies to e.g. photos (unlike Windows' high-contrast accessibility themes) it's overkill... and because it's global, some things are actually harder to discern.

I jumped the gun installling non-TW ROMs, so haven't tried any of Samsung's themes yet... I'll check them out tonight. With LineageOS, I purchased the Sungtratum Substratum addon and Swift Black theme, which worked very well, but as you say the performance issues and missing features seem to defeat the purpose of owning decent hardware. [EDIT: I'm sorry, that's very rude! I don't mean it so bluntly: I probably won't use e.g. the camera much so can understand that many features are not a priority for users, including myself. Now that I've had a better look around (and still only seen maybe 5% of what's on offer) in the ROMs, all have excelled in different areas and the work that goes into them is incredible, especially for FREE!]

Ah, I noticed Adiutor included in a couple of ROMs and see that it does all I need—just basic tweaking in discrete profiles like ThrottleStop/Afterburner for Windows, triggered with events via AutoHotkey (Tasker looks like a the best equivalent).

(Just bolded points that I saw for easy reference) Samsung doesnt lock things down that bad, most stock ROMs regardless of manufacturer are a little inflexible for various reasons, think of it like an iphone treatment. The custom ones are very flexible IMO.
As for accessories, I know you didnt ask, but screen protectors are hard to come by due to the curved screen - glass ones have poor fit and never have sticky surface the whole way = dust can come underneath + poor sensitivity, film ones tend to lift up on the edges . and once you do find a reasonable one, normally cases cause the screen protector to lift. I highly recommend a film screen protector and a case that is friendly on one. I personally use an unbranded film protector from a street shop haha BUT I would highly recommend the supcase unicorn beetle case as it has a part that comes from the front (rather than most cases that only come from behind) meaning that it keeps the protector on very well, even an unbranded one such as mine.

Both boxes are quite easily ticked. Theme store sounds like the solution for you - like i said earlier, plenty of black and white themes. Superman ROM also lets you change the colours for notifications as theme store wont change that. Attached some screenshots of my phone's UI just to show you that it can be done with touchwiz.

Adiutor is not bad and is is very stable. If it does all you need, then dont even try synapse lol. Synapse was hugely frustrating to me - unstable AF, not something I needed controlling my kernel.

My stats are also all while connected to android wear, location always on and sometimes bluetooth audio in car, so you may get even better. If you need any battery saving tips, I can help out as well. Alot of tricks are simply just changing settings. There are apps that can help too.

Considering V20 with Lineage OS. Anything I should look for, or be aware of?

I am looking to switch from my current phone, and want to give Lineage a try.
I am seeing conflicting information. Does the 2nd screen work with Lineage? If it does, or doesn't what will I experience either way? A large chunk of black real estate on my screen? or will the main screen cover the whole screen? I don't mind tinkering, but my main goal is a fairly stable/usable phone without Google. I am also considering a Nexus 6p, but if I can make a v20 work, I prefer the replaceable battery.
Any input is appreciated.

Big laundry list of problems, no 2nd screen, no volte, no wifi calling, issues with the camera, you have to use some half ass work arounds to use, and I'm sure a bunch of other stuff. Go read the lineage threads

Surprisingly not that many conflicts expect for 2nd screen which I don't use so for me it's daily driver material
the second screen area is blank, you can tell its on but the backlight is on minimum, you mostly stop noticing it after a while. There is some work going on behind the scenes to get it working, but don't count on it til you see it.
Honestly the V20 seems to be a phone that is best with a stock based ROM. Super V20 for example.
The main losses on lineage are the second screen and the dip in audio performance. However, as a rom I think lineage performs better than LG ux, with fewer bugs and more relevant features. Plus, lineage is regularly maintained and updated, unlike LG ux which hasn't seen a rebase for the entirety of the lifespan of the v20. There's a balance between software features and hardware functionality you might want to test for yourself.
progresses with the second screen on lineage os ??
I am curious about the progresses that were made on the second screen on lineage os : is it more usable now or is it better to not use the second screen with lineage os ???
... thanks !!

Now the second screen works on specifically marked builds of lineage except for landscape mode where it rotates the second screen making it mostly unreadable.
Now everything is working

Camera/Notch Animation (As Seen On S10/S10+)

Hi Guys,
I noticed Samsung included a nice futuristic animation that goes around the front camera cutout whenever you try to unlock the phone or take a photo with the camera.
I was wondering if it's possible to get the same animation on the OP6T, around the notch, whenever one gets a new message.
I understand there's the scare of screen burn, but i think if it's well done, it can look quite nice and solve the issue of lack of notification LED.
Anyone?
That would be really nice if someone could do it ! 1+ from me !
I doubt it bc 6t notch is not embedded in the screen like the s10... But you can try this....

I'm not sure about the technicalities, so i can't say much!
But when it comes to the apps everyone is using out there, they seem to hurt the battery life and are sometimes unstable, while this feature would be extremely slick and helpful.
Samsung also did it with a notch on their M phone, I think. So it's possible. I'd really love to see that implemented by OnePlus.
How can we get this to the attention of the developers?
fixed it
use the app KLWP and code yourself a good live wallpaper, worked for the notch of my pocophone f1
Is there a way you can share that and explain how you did it?
Why would you want something goofy like this, witch, since it is an animation, will take video memory, processing speed & battery life to perform? I hear people complaining all the time (not just Oppo phones) about phones being slow, poor battery life bla bla bla.
All that glitter/bling/eye candy comes at a cost.
I for one, turn on developer options, and set all my graphics to 0.5x.
If I wanted goofy animations, I'd buy an iPhone.
