New SW was certified, version 15.3.A.1.14.
For C2105 only.
I hope it will be released for all regions and BUG FREE. Is there proximity sensor bug fixed?

Sorry guys, proximity sensor problem is still there in my handset even after updating to latest firmware 
Visit repair shop maybe?
If the problem does not disappera with firmware upgrade, it could be it's in hardware.
No, I think its not because of H/W issue, it is coming only when my phone is locked and got a missed call, and it will disappear if I dial the number and disconnect.
Adding One more problem to the account, it is taking too much time to load an image while opening from album, have anyone felt this after the last two updates? I've started feeling it from the second last update and it still persists
Advice for update 15.3.a.1.14 on Xperia L:
I noticed bugs in this update: If the mobile is in low battery mode the box "adapt lighting conditions" turns unchecked and is not re-enabled when charging the battery. Occasionally, when you connect the phone charger, battery not charging, still reporting charging in the screen, this is solved by trun off and on the mobile.
I hope this help to developers. Let me know If I have to send this message to other page.
Bye!
