I have heard a lot of reports the last two days of the Gmail app causing people some heartache. It appears the most common problem reported is flickering of the screen when scrolling, and troubles getting to the inbox. I personally have not experienced this issue, but there’s enough people complaining about it to be ignored.
Google confirms and acknowledges the issues and says a fix is on the way. GooglerBrittanyBee explains thusly in the Google Product Forums:
Beginning this morning, we’ve received reports of a bug causing some Gmail users on Android to experience screen flickering when they open the app. We are in the process of fixing it and the issue should be resolved shortly. We apologize for any inconvenience.
Clearly they are not wasting any time tackling this issue. I’m very pleased to see them acting as fast as they are.
