After updating device (Iqoo 9 Pro) to OS 15 it's showing many bugs like,

1. Network problem (internet connectivity slows down and even become worse, many times disconnect in the middle, phone shows not reachable to other person)

2. Scrolling down the display slows down and doesn't come smoothly.

3. There are many problems in status bar section while showing notification (many times it comes at the centre which comes across front camera module)

Request to solve this bugs as soon as possible.

Thank you
