Sony Xperia M Network Problem

[skarora007]

Just got this phone and within 4 days, twice it has gone into such a mode where I see full signal from the carrier (Airtel/Vodafone etc), but I don't receive any incoming calls, nor I can make any outgoing calls. Others who try to call me get the message that it's either switched off or unreachable. And when I try to make an outgoing call, it just keeps on going forever without actually getting connected.

Have been using the phone for about 2 weeks now and almost everyday I've to reboot my phone to avoid it going into the above issue. If I don't reboot, automatically it goes into that dormant mode without my knowledge and no one is able to call me up unless I realize that myself.

Has anyone else seen this kind of behavior? Is this already a known bug with this model? Any help, please advice.

Thanks,

Sunil

Dear Xperia Support, I'm facing the same problem as skarora007 and other users in this Subject, since purchasing the phone last January.

once a day minimum, after receiving the call my phone freezes for a while, I cannot hear the caller. After trying to call back - no success. The phone is silent. Other callers cannot reach me until I restart the phone. 

What is the reason? Any updates to the problem (software update, phone change etc.). Let me please know if you need any details.

thank you.

Hi @enano16

I suggest you to first run a backup of the device information like this:

Try performing a system repair using PC Companion:

http://support.sonymobile.com/gb/tools/pc-companion/

This will factory reset your phone and erase all data. You might need tocharge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process. If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP.

In PC Companion you press start on Support Zone -> Start on Update the phone/tablet software -> Repair phone/tablet (the blue clickable link in the message) -> Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

If it's not possible to perform this software repair, you could check the following FAQ topic regarding USB connection problems:

If it nothing seems to solve the problem, you have to consider visiting a sony service:

I'm at disposal for any question.
