Since the NF1 fw, which was the first "bugfix" that fixed GLONASS, kids mode...etc I'm experiencing lags with all the messaging apps, including whatsapp, facebook, twitter. It seems that every app related to a social network lags. The lags are only in the transitions and animations one I opened the app. If I close it, the phone is super smooth again! I seriously don't know what to do, I've tried everything, wipe, reflash...And it happens with every FW after NF1, even the latest NG8. Please can you help me? I just can't stand those lags, I have a quad core phone, I want it to be smooth as it was before with previous KK firmwares!!
