Problem whit network coverage - Amber, L720

[bornacid]

Hi guys,
I have a huge problem with the network coverage after AMBER update. Most of the time I have 1-3 bars network coverage, and sometimes lose range. And sometimes during conversation I just lose connection. Before Amber update I didn't have this problem, help :unhappysweat: !?

Already tried:
- switch 2g-3g
- turned off data transfer
- turned on flyght mode
- I pulled out sim card
- and volume down+power button

Never tried soft reset, did you?
Rub the golden part of your sim with a pencil eraser, helps

Yes - never tried soft reset, i think this is a software problem, because after update start this problem. I work with this phone and im afraid to lose my data and contacts, i guess have to do some back up...

You don't lose any data for doing a soft reset. Just hold the vol down+power key for ~10secs till it vibrates.

Rub the golden part of your sim with a pencil eraser, helps - no effect.

Try a different operator sim at the same spot?
And try your sim in another phone?
