Well I rarely use my phone on direct sunlight or ringer profile so I can't answer that, but 1 bug did occured to me.. I'm using nova as my launcher instead vivo (and set nova as default home), sometimes after login with fingerprint suddenly changed again to vivo launcher.. but now its seems gone after the beta update..Many of the users were saying they were having heating issues in outdoors. I play COD everyday probably more than half an hour or so. Although, its not that much of a gpu/cpu intensive game. I can say that the phone remained cool throughout.
Bugs i have noticed:
*Ringer profiles doesn't work properly sometimes. (Makes notification sounds even in silent mode)
*Vibrate while other partie takes call and drops does not work anymore.
Are you facing the same?
