Bugs that are still remain on .257 firmware

[zxcvbad]

1.Calibration of the touch sensor still isn't there, makes it hard to write gesture with one hand.
2. Wifi still drops connection
3. Some menus (apps and system) are not accessible during voice call
4. Voice dialer doesn't dial numbers under the lock screen,you have to switch off protection pattern or password (but that's not a solution)
5. Sony unlimited video doesn't display hd movies only sd, play movies says hd movies are not supported.

Possibly there are more bugs I just haven't noticed yet, it's only few days I have this firmware

My Xperia Z Ultra doesn't have notification to update into .2.257. But when i use PC Companion, the system update notification (.2.257) is appear. Is good to upgrade or no? Cause for now, i have trouble about the display, cannot off after screenlock. And make it possible to wake up the phone so long time.

Some Glitches I noticed after the upgrade:

1. While setting new wallpaper screen flashes as if adjusting to new wallpaper and once done...while going back to app tray and coming to home... mobile seems to flash along the bottom part were controls are displayed. After few happenings this disappears and very thing returns to normal ie transparency is restored.

2. While playing music using headset, once paused after sometime head set control was unable to regain control of the app.
