Hi,
Sure many experienced the following issues:
1- extreme heat issue.
2- general performance issue lagging, slow.
3- camera issue : sound durind video recording is really depressing me, lunching cam application while phone is lock becomes inconvenient since some time the application start with black view as if lens in blocked or it doesn't start at all, or its starts for almost a second then lock screen reappear.
4- whats app is lagging.
5- keyboards are lagging too.
This is so far are the issues i've re-installed the software many time (before and after December update), so it clearly an Oreo issue. So any are the ant sloutions or advise?! Except rooting the phone.
