These are all the notable OneUI 4.0 Android 12 problems I've encountered while using it on my unlocked Galaxy S10 in the UK
- Battery drains faster, especially when the phone is on sleep or using 4G
- Documents tend to lag while scrolling with a lot of text
- Random screen dim occurs occasionally while in the same lighting
- scrolling through settings and apps with a lot of on off buttons tends to enable haptics randomly
- Memory usage with nothing open is noticeably higher than the previous version (3.7GB/8GB). Doesn't mean much unless you multi task often
- Some simple apps take longer to load like Twitter
- Some overheating issues. My phone is actually warm to the touch now just using this app!
- Connecting to my Watch3 required pairing again for some odd reason
- Fast charging takes a while to kick in
