Some questions before buying G8142 - Sony Xperia XZ Premium Questions & Answers

Greeings, I wish to buy XZ Premium and the model will be g8142 in my country. Before buying I would like to ask some questions.
1. I need to root my device, and it seems that the rooting method only support Android 8.0. So sould I flash stock 8.0 ROM before rooting?
2. I heard that rooting will damage the camera function and make it green screen or something. Camera is a very important part to me and I wish to retain the original quality as the unroot stock ROM. Is there any way to fix it?
3. LG's app will crash if I change the resolution in terminal. Will Sony's apps crash or cannot be used if I change the resolution to 1080p and also lower the DPI?
4. Anything else that need to be noticed after rooting and need to be fixed?
Thanks a lot in advance.

Hello to can root your device and if you unlock the bootloader some fonctions will stop working but we have a fix for that and for the resolution it's normal they are many app who doesn't even support 1440p

1. You can root any ROM, just flash magisk in twrp.
2. There are drm fixes available, e.g. Janjan's kernel, xperifix.
3. You can change the screen resolution to 4k in adb but not every app is working. No need to change, default 1080p is all right.
4. Every time you have to update the software manually and apply drm fix if you unlock the bootloader. Android Pie is probably going to be the last major update for the phone. There are not many custom roms out there.
You are welcome.

Thanks a lot for the reply! Helps a kot, please allow me to ask a little more
1. https://forum.xda-developers.com/xz-premium/development/kernel-sony-xz-premium-5-2018-t3784669
Does that mean most of you guys are following this guide to root and no issues occur in rooting g8142?
2. Drm fix really can solve the issue of camera of rooting? e.g. green photos or easily overheat, because I am buying this phone for the camera quality, if this is uncertain then I will consider another phone.
3. About resolution, from what I saw in the demo phone in my local store, the screenshot of XZ Premium is 2160 x 3840, doesn't that mean it is always on 2160x3840? I don't want such high res and I like to make it always 1080x1920.
Hope it wont make Sony stock app crashes... Will it?
Thanks in advance again!

1. Yes that's the drm fix. After you've flashed the official firmware and then apply drm fix.
2. What drm fix does is that it tricks the phone to think that the bootloader is not unlocked. You can check *#*#7378423#*#* and then service info, configuration, it will say bootloader unlocked allowed: no. But you are still running the phone with an unlocked bootloader.
3. The phone will stay at 1080p unless there is 4k content, or 1440p content...if you change it in adb, when you press the app switcher button, it will show every app as black colour, no content. I have manually changed it to 1440p before no app crashes, 4k is not good because there might be some issues. So I switched back to default which is 1080p.
To be honest even it is on 1080p the screen looks fantastic. I bought it only because of the screen. Proudly G8142 owner here...

It is the square button on the right hand side of your home button(app switcher). When you press this, all apps become black, you won't see the preview.

Nice to know. After change what happen with your screen ? I need change launcher or not ? Also if i using xposed change to smallest resolution will not destroy nothing ? What about installed apps ?
No you dont need to change Launcher! Only APP i have a little Problem is EBay... I have a overlay in "My EBay" but when i open My Reviews and go back the overlays are gone....i can live with that!
I don´t use Xposed but like i sayed its save so test it and let us know ...but there should be no problem!
I think Xposed does the same like this Mod but i´m not shure...i think it changes the Screen Destiny...so if you do this ADB mod it should overwrite the Xposed Setting...should be save for you...
With this you Change Screen Resolution AND Destiny

Well i must think about this change. Two more question your screen after change still is full on phone or not ? This also minimalize temperature ?
Screen will be full only but in recent apps screen you'll get to see those big fonts. I don't how to change that. Maybe you can or maybe you can't. But it didn't affect anything. Screen is proper and working for the basic apps that come with the phone like camera, dialer etc. I've tested games like Nova 3, beach buggy, temple run.. They run noticeably better with 320 density. Try it. If you don't like it you can change back without any hassle.
Screen is still Full...its like changing resolution on your Computer Screen
What do you mean with Temeratur?

There's a free app to apply the changes with ease: https://play.google.com/store/apps/details?id=com.nexter.miniscaler

Means Unlock Bootloader
Means loosing Warranty...

No hurt to try. You can use the steps in the first post but you need to change the build.prop with the exact same DPi too, to void most of the wrong image previews.

Moto Camera misbehaving with custom ROMs

I experienced an issue with two custom roms (LineageOS 14.1 and ResurrectionRemix 5.8.1) regarding the following applications:
Moto Camera One ( play.google.com/store/apps/details?id=com.motorola.cameraone )
Motorola Camera ( play.google.com/store/apps/details?id=com.motorola.camera )
The issue is, there's a slight offset regarding touch controls with both these applications. The closer to the bottom of the screen, the higher the offset, in fact, it's only possible to get past the first start screen if you're holding the phone upside-down, else you're not able to press the "next" button because the touch offset is so extreme the place you need to touch is really far under the screen.
I did not experience these issues with the stock 6.0 rom, only the two mentioned above.
I really hope there is a workaround with this because these are the only two apps that allow slow-mo recording and 720p60fps recording, as every other app I tried (including the so acclaimed Cinema FV-5) did not allow me to record anywhere above 30, saying that "the camera doesn't support it" which is just bs.
Thanks for your time and I really hope someone can provide a solution.

This is happening because you have changed the DPI in your phone. Moto camera does not work when you change the DPI. Set the DPI back to default (320) and it should work.
Here's a moto camera with multi DPI support:

Probably this is the thread, OP contains the same URL.
If we could know how they achieved it, if possible we could do for the G3 camera. The settings wheel was very adaptable and cool

My XZ Premium native album app no picture quality enchanced!

With sony stock album app to check pictures, I found no picture quality enhanced. Unlike its predecessor Z5 Premium which utilize X-Reality to pictures in Album app, XZ Premium just let the picture native(I've not noticed any changes opening the picture!)! So is only my device problem or you guys the same?
No one?

Maybe Sony canceled this function...
@64801965, as far as I can tell, video enhancements feature may show some improvements only in playing a video within the sony album app.
But you need either still locked phone or restored locked TA with kernel hiding bootloader unlock on pie to have it working. There is no drmfix for pie and therefore this function is not available if BL had been unlocked without TA backup and not running bootloader hiding kernel. See here for additional info.

So it's for video, as well as photos?
@64801965, in my opinion, it influences only video - after all it is called like that: "_video_ image enhancement", even the description in the settings menu mentions video only.
There is a sample shown in the settings menu to see the difference on split screen.
It is possible to extract this sample from an .apk a play it with Album app and see the difference in there when the video image enhancement is ON _and_ working in the settings having the screen split in two there.
But in my opinion, it's only a gimmick making the colors more saturated.
Moreover, if you export the video to PC, no enhancements present.
Most likely even if you play it by something else than Sony album, no enhancements would be there either.

New LG Home APK, Camera and more

7.20.56 is available on APK mirror. I wanted to give it a shot to see if there are any improvements and surprisingly it seems much smoother compared to previous versions and the best part is that it's compatible with Quick-Step so all gestures work correctly. You get a dark Google feed and it doesn't seem to be as slow and glitchy as it has been in the past. Also an update to the camera app is available as well that comes with a few new tricks as well! Does anyone know what phone these are pulled from?

Yep, once the app is "upgraded" (becomes a version other than the stock one (usually the one provided most recently through software updates from LG), a small menu becomes available in the app settings (ie App Info > Camera). This menu allows you to uninstall updates to the application and revert to stock.
I just uninstalled the latest camera update (the one listed here) since it didn't really change picture quality and has an icon for "Show new features" that crashes the app. I did update "Home" though and it feels a little better.
Weird, I don't have that icon. The Manual focus seems to be improved, and if you swipe and hold the shutter button left/right, or pinch the screen with a gesture it switches between wide and normal lenses. I don't remember if the previous version worked like that. I feel like AI mode works much smoother, and portrait mode with it's blur adjustment function is improved, but it could just be in my head.

You have to be rooted on Pie and have the Quickstep Magisk Module installed. Using a launcher other than the LG Home launcher, open the Quickswitch app and select LG Home as your recents provider. The module will run a script and reboot your phone. Once your phone restarts, then set LG home as your default launcher.
camera is worse and for sure is from another device
It's definitely for a different device, but I've had nothing but good results.

Screen Mod for Newbies

Hi to all.
Happy with my Fold 2. Would be extremely happy if I could make one mod without root:
If apps (and UI if possible) would behave as if though there was no punch hole!
I'm not talking about the setting to change the aspect ratio of an app.
Some apps don't work properly even if you do that.
Any way to just make the phone work like it had no camera at all at the front (of the big screen)?
Please keep in mind that a)I'm not a programmer , just a user
and b)I don't want to root my device.
Thanks in advance

This is what you want, very easy to enable. The video shows the Note 20 Ultra but it also goes for the Z Fold 2.
Settings/Display/Full screen apps/advanced settings (tap upper right 3 dot icon)/Enable camera cutout.
Thanks but nope.

Thanks for your reply my friend but that's exactly what I want to avoid in the first place.
I want all apps and ui to use Full Screen without a black bar.
In other words all apps to use all the screen real estate like there is no camera there. Most games and apps do that but not all and browser also leaves that part blank when in landscape mode.
I know it can be done but I don't know how
Thanks for your reply though.

I heard there is a way to do it by connecting the phone to a pc and typing an ADB command (if I'm saying it correctly) but I havent located the article or the way. All I know is that it can be done, but apparently there is no simple way. Maybe a more experienced member can enlighten us.
You can download multistar together with tasker and autotools. Should give you the desired result without the needs of root.
