Some situation/bug? that I facing after Android 15 update

[WerezPlayz]

This is the problem I facing after updating to A15 for around 5 days.

• After Android 15 update, I notice that when I use X Mode inside setting icon and volume control is not like before become red colour, I'm not sure is it removed by DevTeam or a bug. Example as file attached.
• Other than this, I noticed my lock screen brightness is darker than home screen and after I restarted the phone it become normal. I also noticed that brightness is lower than in A14, I turned on extra brightness, when turn off it a lot darker than A14, brightness level on daily I put 50% so I really easy caught the difference.
• I also noticed screen refresh rate is not like what it should, I put 120HZ all day and I notice it does not feel like 120HZ sometimes, it lag out and normal again. I can't to make this happen and record again to show.
• Apps lock, it really easy to noticed that it slower to open than A14. Recording, when I recording a game, my game fps dropped really really bad. 

The Improvement I spotted in A15

• Battery consumption. It lower than A14, battery drain not very fast now.
• Performance. The performance is  slightly better in some game, although it very slightly improvement
• Temperature. So far I play Zenless Zone Zero and CPM2. For ZZZ, max graphics with X Mode with normal house stand fan, A14 could reach 46℃, A15 now cooler a little with 43-44℃. As for CPM2 all max settings with X Mode with stand fan, A14 and 15 not big difference could reach 47℃ but A15 slower to reach
• Overall, the phone does become smoother just have some bugs that causing the phone not work as smooth sometimes.

That all for now, I hope AsusTeam could do more improvement in their systems. Hopefully AsusTeam saw this forum and inform their DevTeam to spot and fix. Thanks AsusTeam.

Hello @WerezPlayz 

Thanks for letting us know, I am sending this information to the dev team.

Normally optimization takes place after a firmware update and it might take some time for the system to fully optimize.
To avoid most problems it is recommended to do a reset to get a clean install after a new Android version upgrade, since in some cases some left over code might cause issues.

Could you provide more details about the specific issues you're experiencing after updating to Android 15? Common problems that users encounter after system updates can include:

1. Battery Draining Faster – A bug that sometimes causes the battery to drain quicker due to apps running in the background or new features.
2. App Crashes – Certain Lightroom mod apps may become unstable or crash after a system update.
3. Performance Lag – The system might feel slower after an update due to background processes or unfinished optimizations.
4. Connectivity Issues – Problems with Wi-Fi, Bluetooth, or mobile data after the update.
5. Touchscreen/Display Problems – Issues with the screen’s responsiveness or display glitches.
6. Audio Problems – Sound or microphone issues that might occur post-update.

Let me know if you're encountering any of these or something else, and I can suggest potential solutions or troubleshooting steps.

After 2 days I believe after I posted this forum,

• Noticed my phone battery drain lot faster just by watching YouTube
• App crashes no for now, I don't face any app crashes
• Ah yes, performance seems to be not as before. I played Genshin Impact few days before A15 come it smoothly, then after A15 update I noticed I just run around it frame drop to 45fps
• Connectivity issues so far also no problem for me
• Touchscreen problem is also no, but display. Lock screen brightness is lower than unlocked screen/home screen. The refresh rate 120Hz buttt, sometimes on home screen just swipe to find apps also lag.
• Audio don't have any issue for me too

Add On

The heating issue also the same time happening following battery drain issue, same thing, watching YouTube 1080p60 video and got up to 44℃, it shouldn't be that hot
