I went up with small issue and now it ends up with bigger issue.
Heating issue was the main problem which i was dealing with, so i decided to resolve it in my nearby service centre as it was in warranty period.They changed my motherboard and on returning it my front display glass and back glass were having cracks therfore i told them regarding this issue and they decided to change both glasses.After replacing it my front display come up with another issue where my pixel brakes or get blurred while playing videos which are in darker side.So i again went there to resolve this problem and they said its due to the new update and its a bug .even after update it persists .I cross checked it with y friends phone with same update they are not facing these issues.Today i got a call from service centre saying that they they cross checked it with another phone and there is no issue.I showed that pixel breakage in front of me and they are saying that they cant see it.
