iQOO 13 is facing several issues 

1. Heating issues on normal usage 

2.  Whole UI has touch response issues and throttles as soon as device heats up

3. Camera ,omg the team completely sucked the camera performance of this phone.

They just hype for the flagship and now iQOO 15 is about to launch and they'll degrade the performance of iQOO 13, already they made it useless.

I request if any user is watching this go ahead and purchase OnePlus or Samsung in Android but not iQOO , you can even choose vivo but not iQOO.
