Thank you very much for your reply!

I also own an A12, and OneUI 4 (CORE!) is lovely. However, this device is seriously underpowered. It can barely render the animations, the LCD display is awful, connectivity is also poor, but the battery on that phone is impressive.

I’m on a tight budget right now. Buying a new phone right now isn’t a great choice, but I could live with it. My current phone is literally enough for me, except for the battery (I fixed this problem with an external battery)

Money is a bit of an issue right now, since I am currently spending heavily on home improvements. A truly expensive errand!

My S8+ works so well! The animations are super fluid, the apps load pretty fast, and overall my device hasn’t really slowed down.

Yes.
