After one ui 7 update no front camera light animation in m35

Why there are unstable 5G network in my Galaxy F14 5G while using hotspot?

I am using F14 5G phone since 2 months and i am facing some issues with phone.1. Screen flick issue before and after update. 2. Suddenly screen goes to sleep and wake.3. While playing youtube suddenly sound goes off and start after restarting the app...

After updating one UI 6.0 my F14 5G phone is not able to connect with smart tv. My tv is not connecting with my phone's hotspot. This issue occurs with android tv and samsung smart tv both.
