Are you getting this issue after the June update?

[Anonymous]

yes 2 .1. and I flashed firmware from service center then also display colour banding issue present

[werockpokey]

Hmm...if the issue is there even after a clean install, it could potentially be an issue with the current update.
I believe there is no safe way to roll back, right?

[Anonymous]

no ...you have to root for that....i don't want to roll back because otherwise device is like champ.....only this 2 issues present.....it's definitely software issue it's because i am using iris biometric for secure folder also ...no problem with that no black iris scanner area....if it was hardware issue then both iris biometric can show their fault......and display banding issue is there....means display colour sometimes normal sometimes dull like

[werockpokey]

Yep. Same here. Everything was working absolutely fine before the last update.
