[Sony Xperia XZ Premium ROMs, Kernels, Recoveries, ] WolfAyron:
Update on issues that I've come across so far.

(I know there are some that I already posted/mentioned before. But I wanted to collect to have them in one place.)

1. No split screen function in gesture mode – SOLVED

It turned out accidentally, that the way how you can use split screen with gesture controls is to go to recent apps, and long press on the icon of the application and it opens a menu where you can see the split screen option.

2. In gmail, company email address requires screen lock method after every reboot. – SOLVED

There is something wrong on Google's side because after installing the stock Sony Email app, and setting up my company email address it's just working fine. After rebooting the phone, it does not require giving screen lock method again like Gmail does.

3. Google apps cannot communicate with server via carrier network/SafetyNet Check API error – SOLVED

After searching forums and websites literally for hours, I finally came across the solution why my Google apps could not communicate with server via carrier network but on Wifi. Someone advised to check whether the Google Play Services app has background data enabled. I checked, and it was not enabled on my device, and I don't know why. But simply turning on background data solved the problem and now every Google app communicate with server on carrier network.

This thing also solved the SafetyNet API error in Magisk. So now it passes both basicIntegrity and ctsProfile on both carrier and wifi network.

4. System UI freezes/hangs while connecting to a bluetooth device. Notification/qs panel does not react for seconds.

I noticed that when I turn on Bluetooth in QS and turn on the bt speaker (SRS-XB12) or headset (SBH52), while it connects and establishes the connection the whole UI freezes for some seconds and the notification and qs panel also does not react to anything. But after that everything's working fine.

5. Force dark mode switches off after reboot.

As title says. I usually use not only dark mode, but force dark mode also on my phone. After every reboot, the force dark mode switches off.

6. Brightness changing in some apps (MX Player, YouTube Vanced) does not adjust the device brightness.

I noticed in MX Player and YouTube Vanced, - where you have the ability to adjust screen brightness by just sliding your finger on the left side of the screen - that it does not change the brightness at all. I have to pull down qs panel, move the brightness slider a bit, and after that I can control the brightness within the app by sliding my finger on left side. But every now and then when I open the application again I have to do this. Because on first try it never wants to adjust brightness.

7. Bluetooth media streaming does not automatically switches to connected device.

In one case (my SBH52 headset) when I connect it to my phone via NFC the phone shows as it was connected and media sharing also enabled but when I start playing music it still comes from the phone's speakers. On the right volume panel, the option shows up, to choose the output device (Speaker or SBH52) but choosing the headset, it does nothing. I have to go to bluetooth settings, open the connected device, choose disconnect, and manually tap on connect again. This way finally, the output switches to the headset and I can stream the music to it.

8. Cannot create Settings shortcut (widget) to home screen

As title says. I want to create some shortcuts to different settings but it does not list anything.

9. Whole System UI freezes randomly

Like others also mentioned, the SystemUI freezes for no reason. This issue appeared to me only 3-4 days ago and since then, it happens often. Many times a day. I noticed this usually browsing the internet, and switching to previous apps.

Sometimes I can only swipe left or right at gesture bar and open notification panel but everything else is frozen. Sometimes it does not react to anything but the notification bar only. Again sometimes I can only swipe up from gesture bar to go to homescreen but cannot do anything else.

To solve this I have to restart SystemUI.

Many thanks in advance for your work, eliminating the bugs!
