I know this thread is about firmware 15.3.a.1.12 and latest .17 but i gave up on trying to make this proximity bug go away in these firmwares. I just wanted to say that I figured out that firmware 15.0.a.2.17 (Jelly Bean 4.1.2) doesn't have annoying bugs. Maybe the camera works a bit worse than in the other versions of softwares but that's not a big deal for me. Firmware 15.0.a.2.17 is ugly (list of applications) but I use Nova Launcher which is free at google play store and now my Xperia L works very smooth. That launcher is really great. I almost gave up on this phone and wanted to buy some other(not Sony of course) but then I managed to make it work stabile with this version of firmware. Just wanted to share this with you guys. I attached 2 screenshots which show the look of this launcher i use.
