So many bugs I noticed after upgrading to One UI 7.
- Battery backup reduced after One UI 7. Refer to the screenshots. (Major issue)
- Phone is heating up unexpectedly, even without intensive use. It was heating up while I wrote this. I restarted my phone and optimized all apps using an App Booster, but I'm still experiencing battery issues.
- Last 5% still drains in 5 minutes (this issue was there in One UI 6 as well)
- The screen lock is taking a moment to turn off screen when using the double-tap/side button option.
- Sometimes the notification panel shows the quick apps button from the lock screen. This happens mainly once after a restart. Refer to the screenshot.
- When getting a YouTuber's response to my comment, while replying to it again, I always get a black screen in between. Refer to the screenshot.
- If you have image widget on lockscreen then when you restart your device unlock for the first time and swipe it you will see widget image in the notification panel.
Earlier I used to get more than 22 hours combined.
Quick App button coming in the notification
I got a reply. I was trying to type something, but upon selecting text, this black screen appears. This is always happening.
If you keep the swipe down for the notification panel and panel settings together, then swiping anywhere on the homescreen causes the top bar to blink.
One UI6 backup. Clearly see the difference; even after playing games, there is no heating, and I'm getting more than 19 hours.
See my recent one UI 7 post ull know how bad the battery issue is
