Xperia Z5 E6603 laggy after latest update

[luisporrasarce]

After the last 7.1.1 update, my Z5 started to get laggy and hot. Try to go from app to another or go from home to app drawer and the previous screen is still in the background. After several minutes of usage, the phone started to act normally, but it gets very hot. The last update really ruined my phone.

Hi... already tried that, no luck. No errors reported.

Since the responses in this forum were useless, I decided to flash CarbonRom into my Xperia Z5. All the problems are gone, the phone is running faster and the battery is not draining. Good bye old stock rom!
