We’ve seen a bunch of reports online regarding the Gmail app that seems to be causing a screen flicker, and being unable to get to the inbox. We never experienced it here, but that doesn’t mean it wasn’t happening, as forum threads were popping up all over the place.
Google revealed that this issue is real and a fix is on the way. BrittanyBee 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.
Glad to see they’re on it so quickly :-)
