I have purchased sony xperia c c2305 4 months ago and since last one and half month m facing network problems... Network signals disappear after 5 min of usage. No network coverage on continuous base of 15 20 mins..! I thought it might be problem with my idea operator so i switched over to vodafone but still facing the same problem.
I took the cell to sony service center but the problem is not resolved.
I am again going to visit sony service center one more time and if m not been resolved with my problem i am going to file a case in consumer forum against sony and croma store from where i purchased this cell.

Hi there,

Perform a software repair using Sony Update Service.

Sony Update Service

Make sure that your battery is charged at least 60% and if you want to backup your important data, read this topic:

Backup & Transfer

If that fails, I'm afraid you'll have to take it back to a service center for further examination.

Keep us informed.

i went through software repair via sony center only but found no results...

i again visited sony service center and submitted my issue. got a call from there that there is problem with my sony xperia c mother board. they are going to replace a new mother board in my cell and i will get it back in 4 to 5 days.

lets see what happens.

have you tried clear the port and proxy from apn settings?

go to settings >> more... >> mobile networks >> select sim card >> access point names >> choose your active apn >> clear only the port and proxy

I tried everything.
There was problem in its motherboard. Sony service center replaced a new motherboard in it. Now its working well.

I have weak signal problem in Sony Xperia c SIM 1. slot. but i  solve this problem  in my sim 1 slot . Later I found that my cell phone has 2 option 1 is WCDA network and other GSM network .  When I select GSM net work only then my problem gone away . I discovered that when  disturb in wcdma network by network provider that time it was happnen . Please do that then your network problem will difinitely go . There is no problem on SONY Xperia C . I believed that . Good luck
