[Q] No Gsm Signal On Xperia Z

Hi guys,
I have a gsm signal problem with my my xperia z.My phone can get the gsm signal(2G/3G) very low and mostly time is says "no signal".While my Note2 shows 5 bars of signal,my xperia z can't get the signal.if i close enough to base station,it shows 1 bars,max. 2 bars.
I have tried changing sim card,changing network mode(gsm-only,wcdma only...) , try to select service provides manuelly.I have tried everything.
Please... Anyone give me feedback on this, I'm not sure it Hardware or software problem.
Thank you very much in advence.

Have you tried updating to .434? That solved all cell reception issues for me.

Yes i updated to 434,but this problem still exist.Is any one have an idea??

The phone must be faulty, return it to the store you bought it from or alternatively you can use the 2 year Sony warranty to get a new phone.
Press thanks if I have helped

Xperia V signal antenna problems

Hi
I have problem with signal antenna since 2 weeks ago on my xperia v, I lose my signal antenna randomly, rebooting sometimes help but it is very annoying because I always missing important calls... I googled it and according this threads form sony mobile help center get this result at last: It seems the Xperia V JB 4.1.2 firmware find a new bug for signal antenna. Now, is there any one have the same problem here? I didn't solve my problem yet but I think we can talk about that and find out a ceaseless solution. Please let me know your experience and idea about this problem...
Thank you

i don't know for sure if my problem is related to your's but it's similar i think..
well my one sometimes can't get signal for some while after boot some times..
more frequently it says that the sim card is missing despite showing carrier name and proper signal sign..
i always have my problem solved just by entering airplane mode and out so it could reconnect to network.

It can be firmware bug too. airplane mode sometimes works for me but I have to reboot most of time. another experience or idea?

No idea or experience?

I know the post is old and others, but now I just got a V xperia LT25i.
In which I have had the problem of the radio signal, and it was as easy as that the signal cable inner radius, had broken [incomprehensible], since neither has shock or anything, and it was something sudden, as it has I been running well for a long time, in the hands of someone else ..
So anyone who may have this problem, remove the cover [are 6 or 7 screws], and on the right side check that the cable is good, and if change is broken, and if it's okay, then the problem is Software , rather than hardware ..
Thanks for your effort.
