I am not a tech expert, so I will try to describe the situation as best as I can. Xperia assistant offered to do a software update. After restarting the phone, various glitches began to appear. Phone clock is a few hours ahead, and there are black spaces on some edges (where the screen background is supposed to be).

Ever since the 8.0 update the lockscreen has gotten really annoying. It takes about a dozen swipes to unlock my screen.

After a software update you should always "factory data reset" the phone via back up and reset. This usually solves all bugs. Remember to save you photos etc first.

Translation via Google Translate:
After the update did the reset is still a problem with unlocking. Too annoying!
После обновления делал сброс всё равно проблема с разблокировкой. Тоже раздражает!

Then perform the update again using Xperia Companions "Repair Software". Until you fix it.
I had a similar problem with my Xperia SP a couple years ago.
When you perform the repair make sure your phone battery is fully charged and do not use your computer until the repair had completed. Remove your SD card and SIM too.
I know it's a hassle but if it was an actual issue with the software this forum would be flooded with complaints. So far I've only seen 4 with different complaints.
Keep flashing the update until success.
