I've been using Xperia SP for almost a month now, and em pretty happy with it. However, there are several bugs that should be addressed with the software updates to make the user experience trouble free. I'm on the .211 firmware.
Touch Screen: touch screen behaves strangely sometimes and you have to enable/disable glove mode and unlock again for it to start working normal again.
Antenna: If the phone is in no network area and then you move to a place with good network coverage the phone won't select the network again by default I've to manually put the phone in airplane mode and switch it off for phone to start searching for network.
Proximity sensor: Behaves abnormally during the call. Sometimes doesn't switch the screen off and if glove mode is enabled you are going to start several applications during the call even if the screen is off.
Notifications: Works on their own. If they wish to light up on message they will otherwise not.
Camera: Really, Is this is the 8Mp Exmor RS for mobile you were talking about in the marketing campaign. The truth is there is more noise than the actual pic when i click in most of the lighting conditions except may be for a bright sunny day. No burst mode and No HDR for videos.
