I have Sony Xperia Z for few days now and thought to share few bugs and issues which I've noticed with it so far. I've decided to post them here rather than general forums like xda-devs hoping it will get picked up by relevant people at Sony and actioned if necessary.
Automatic brightness doesn't work as expected
When Automatic Brightness mode is turned on, it is still possible to manually control the brightness using the slider. That's not to say that automatic brightness doesn't work, however the thresholds are too narrow and essentially user is still forced to manually dim the screen in the darkness (as it's too bright) and then max it out oustide in sunlight (because it's too dark) - all despite Automatic mode is selected.
"Automatic Brightness" mode should really be, well, automatic and use full range of brightness available without requiring user to manually tweak it.
Socialife issues
I was really happy to see much better social networking client, a vast improvement over Timescape, however it's still far from perfect. I've noticed several issues around it:
- the homescreen widget keeps way too little history, it should allow scrolling down through much more posts;
- the widget is really buggy when it comes to refreshing stuff, despite setting Socialife to refresh every 30 minutes, it often fails to reload content even after passing that threshold. Also, tapping on "refresh" icon doesn't provide any feedback indicating reload action, which leads to multiple unnecessary taps (as it takes ages to reload content without any indication of it);
- the main app view also isn't very responsive when it comes to loading new content, it seem to take ages to refresh and doing "pull down to refresh" action also often fails.
"Devices" app drains battery
The "Devices" application, which I believe is responsible for DLNA-related activity, does seem to keep device awake in the background unnecessarily. I sometimes display pictures and videos from the phone on my DLNA-capable TV and noticed that each time after using that service, the Devices app starts the battery drain - despite no longer actively used. It also seem to transfer way too much background data without clear reason for it. See few screenshots below:

Lockscreen sometimes ignored
Not exactly sure what causes this issue, however noticed that turning screen on using on/off button, it gets straight to the homescreen, omitting lockscreen completely. It happens intermittently and might have something to do with Stamina mode, as it hasn't happened since I switched Stamina mode off. I'll update this thread once I find the way to replicate this issue.
So these are the most prominent problems I've noticed with my new Xperia Z so far. Hoping these will get addressed in future software updates, as all of them are software-related issues anyway. Will update this thread further as soon as I discover any other bugs.
