Hello,
since 7.0 update on December 2016, my Xperia X began to behave slower than on Android 6.0. I hoped that's temporary problem or another update will be launched with time, but now - after few months - I give up.
I must reboot phone 3-5 times a day, because only after turning off and on my Xperia run smoothly. After few hours some actions tends to stuttering, lagging, e.g. swiping top to bottom to toggle notification bar is like.. 5 sec. before something ever happen? Whatever I want to use on notification bar - turn on or off wi-fi, internet, or read a message - it lags a few seconds before actions begins.
Sometimes I completly can't unlock my phone, power button don't react, it's like a brick. I can't do anything. After 2 minutes it starts to react, the lock screen shows up but in next 1 minute I can't even unlock the phone, nor using a pin code nor using a fingerprint scanner.
What's else? Starting video recording always give a frozen frame on beginning of video. Always. Every clip have a lag on start. I often have to cut out first part of clip if I want a fully smooth video..
Overall - phone run very well for few hours, then suddenly start lagging so hard, so it's completly unusable. I have to reboot it and again it runs okay for few hours, and again.. and again.. And - after every reboot - I have to wait couple of mins because of lockscreen not responding for any action.
So, I done a factory reset and given it a try for a day.. nothing changed. Even on factory setting phone tends to behave in the same way! I consider to send a phone on a guarantee, or waiting some time for 7.1 update (T-Mobile in Poland starts the update, but as well I can wait for it and wait for months for other operators - I don't know when the update show up for my Xperia and I loosing my patience).
Any ideas?
