actually i never can get past the verification phase which they send code through sms. the screen just stuck and i cannot input the verification code (MIUI and other custom rom for mi5 never have this problem)

is apps activity also logged in logcat?
maybe i'll try this rom again and provide the log next time :)

GPS is working reaaaaly bad... Previously I used Xiaomi.Eu 7.11.2 firmware and I flashed 3.1.1 and using Google Maps was a horror ? It takes a long time to find a fix and It was very very misguided, the blue dot główna around on every direction... Today I flashed Eu 7.9.22 and on Miui GPS work great, finding fix on house on around 10 seconds... I flashed later Viper 3.1.1 and at the first try GPS works as good as on Miui... After configuration my phone I tried GPS and it sucks... No fix on buiding all on all :/ Does somebody have this problem?
