No signal

[Vanek]

Hello! Bought xperia V week ago, phone is new. It begin lost signal from bad 3g to very good edge, but then it lost it absolutely to 0. Says that only emergency calls available. Restart helps some time.  Is that known problem? Any solution?

Sounds strange! 

Have you updated your phones to the latest software using PC Companion?

Try to change network mode from LTE/WCDMA/GSM to WCDMA/GSM to see if you experience any difference. Go to settings > more > mobile network > network mode. 

If the behavior is the same I suggest that you try with another SIM card in your phone.

Hi everybody!!!! I Can say that this problem is a flaw Sony firmware Android 4.1.2 for Sony Xperia V.Данную problem is practically impossible to eliminate: reflashing Sony PC Companion or Update Service helps temporarily,as well as rebooting the аппарата.Мне sometimes makes you this way: in the calls menu, dial *#*#4636#*#* opens the tools menu (hereinafter strictly as I point) choose in the phone information lowering turning find below the set the preferred network type select the LTE/CSM/WCDMA and click the Home button.:smileysmileywink:

Jumping in with the same issue - Xperia V is 1 week old, however, several times a day it loses a network. Note that signal level on a screen shows perfect connection and  I can make a calls... but no one can reach me. Scrap. And two more problems: charging indicatior shows everything even mid-summer temperature on Mars, but not an actual charge level (and besides of it, % of charge displayed jumps up and down randomply even if  phone has all services off and SIM card removed) and people I'm calling always hear me with gaps and rumbling

Bump. No ideas? Maybe that's a manufacturers' flaw? If yes, could you please send me an official e-mail with confirmation, so I'll be able to return my phone back to the shop and get a refund?
