I updated my Z1 last Friday to the latest software 14.3.A.0.757. Previously my phone had been stuck on the .290 firmware so this is my first taste of Kitkat on the phone.
After spending the weekend using my phone I've noticed quite a few minor bugs...
- The UI is can be slightly laggy at times especially when swiping left and right on the home screen or within the app drawer.
- Occasionally the touch screen seems less sensitive - usually when swiping left and right on home screen.
- Overall the battery seems ok but when using wifi or the camera it drains the battery noticeably worse than before.
- Sometimes the notification sound effects seem to crackle or get distorted.
These are only very minor bugs which I can live with but by far the worst one I've noticed is when using the camera. If I've been using one of the photo apps like AR Effect or Timeshift burst - when I exit the app, rather than it taking me back to the home screen, the phone loads up another random app instead (usually Google Chrome or Xperia Privilege) this is extremely annoying and seems to happen very often.
Also if I've been using the camera several times throughout the day it seems to become extremely laggy and occasionally stops responding all together. Sometimes it can take up to 10 seconds for the camera app to load. This usually gets worse throughout the day and is normally fixed by re-booting the phone.
Is anyone else having these problems with the camera? I've noticed people on the forum talking about other issues with their camera like over-heating etc but not exactly the same issues I'm experiencing with mine.
