I've had so many issues since this update, battery drain is epic, 10% drain in 20 minutes, also icons/fonts smaller and notifications not showing for WhatsApp.
And earlier this evening, apps kept opening then just crashing and shutting, please fix this or I may consider consumer rights action due to unfit for purpose now.
And........Thats to start with, I think Samsung have really dropped the ball on this one, Samsung if you're listening, please rollback.
