Hello fellow SONY users. I have updated my Sony Xperia z5 Dual to 7.1.1 last week and it worked pretty well for a day or two. Battery consumption is better now. BUT!!! Unfortunately, this happiness didn't last long. After two days my phone suddenly hanged severely and even home screen disapeared (Xperia launcher). The phone became extremely slow so that none of the applications worked. I tried software repair via my PC again. It became good again. but after a 24-hour working with my phone, this problem happened again. Although by restarting the phone the phone become stable but after a day, it will hang again! I tried uninstalling some applications as well to see whether the problem exist or not, but that didn't help. I don't know what causes the problem to the phone. I hope Sony make a further update available soon to solve this problem. Thanks.
