I see many threads outlining issues with 8.1 and the update, if there are issues its absolutely essential the issues are posted and discussed but I just wanted to give a bit of space to users who have found very few issues since the 8.1 update
Personal experience since 8.1 update on a Uk O2 Lumia red 720
No major problems to report ... battery life with data left on 24/7 back to normal as before 8.1
I have had 1 hang/freeze when using viber and that's it... apart from it being dog slow to load but that is the app not the phone, its a crap app
WiFi connections solid
Bluetooth solid
On a personal level I have found 8.1 and the following update to be very good
