Third post down I wrote a list of some, probably permanent, problems of my Xperia L
----UNABLE TO UPDATE FIRMWARE to 15.0.A.1.36 from ...1.31. Tried all available methods. Please provide link to latest firmware so that I can update using flashtool.
The update is not completely rolled out. It appears in the site but might take a week before it isavailable for download. Be patient 
By the way, are you facing data connectivity issues with Xperia L? I have one which shows Roaming in Home network and also not connect properly to internet. Very frustrating 
All radio communication, phone, Wi-Fi, etc., works without any problems on my L.
The problems I've noticed so far are:
1) Very Narrow Camera Focus and Photo Resolution Noise - probably caused by pixel smoothing software, or the actual camera CCD is not an 8MP matrix, but, a composite matrix made up of multiple VGA matrices, or, probably, both.
2) Electromagnetic Interference of Touchscreen and FM Radio - when the phone is plugged in and charging, the EM interference from the charging battery causes various anomalies to the touch capacitive screen, mainly while trying to slowly scroll up or down any scrollable area, the scrollable area, not the whole display, jitters rapidly up and down. This is apparently caused by the capacitive screen's detection cycles constructively interfering with the batteries EM field. Also, there is EM interference to the FM radio in the form of background noise. Unplugging the device from the power source resolves both issues.
3) Problem With Photo Album Cache Address - when using a cache cleaner app, the necessary data of the Photo Album, along with the expandable cache, gets deleted, causing the Photo Album not to display any photo miniatures, although, when touching various locations of the screen in the Album lets you view the picture, thus, only the address of the photo miniatures gets deleted. Manually force closing the app, and refraining from using cache cleaning apps, resolves this issue.
I have not had any other problems with this phone. Waiting to see what the ...1.36 update resolves 😄
I have had the second issue with another phone, depending on charger. Charging with USB from my computer gave it some lag, using a cheap third party charger disabled the touchscreen alltogether. Haven't noticed it yet on my Xperia L.
I have 4.2 JB. I'm so desperate in camera focusing of XL.
In scene recognition, normal mode or what ever mode, if I push haft press that will focus. if i click it to take picture, it will focus again take a blur shot. It is by chance to take a clear shot, neither in touch screen camera button, its the same issue. Sony, please fix.
