I've been using iqoo 12 since July 2024. This phone was working smoothly when it was new just had few bugs in software which was ignorable. But after updating this phone spacially android 15 update it ui feels laggy just like 20k smartphone . Too much lag here and there and it also started to gitter while gaming even while maintaining lower temperature. One thing I noticed that it's homescreen and recent menu was lagging due to wallpaper mainly , because when I used black background it's homescreen become slightly smoother like earlier. And also fix the response time delay while navigating in settings etc. 

(When I bought this phone funtouchos and oxygen os was nearly same and this phone had better gaming performance that's why I picked this phone but after these recent few months OnePlus has improved a lot like it became the smoothest android ui. But my iqoo 12 is still there infact it fell little behind )

So I hope in next November security update atleast performance and ui lags should be fixed and start to improve the ui .
