GCM stopped working a week ago, didn't show my data, sometimes showed "UNKNOWN EXCEPTION".
I reinstalled it today, now I cant sign in. What's going on?
Website works fine, so my password is right. No other problems on the phone, I assume the only problem - is a quality of GCM development.
Sony Xperia Z1 C6603, Android 4.4.2
I'd like to stop using GCM, the only thing I need - Bluetooth upload from my fr220.
