signal problems since lollipop update

[shirley21]

Hi am slowly going crazy with this recent problem with my phone.  Since i updated to lollipop every call i make ends, sometimes after two minutes, sometimes 30 seconds.  The phone appears to completly lose signal so i lose the call then it freezes for approx one min while ending the call! ive tried reseting my phone, ive wiped it and reinstalled the software, ive removed and reinserted the sim, ive tried it in safe mode and ive no idea what to try next...can anyoe help?

What handset do you have?
Have you tried the SIM in another phone?

Are there any network issues in your area?

No problem.  Also, enter your postcode into the Network Status Checker to see if there are any issues in the area ( you may have to zoom out a bit)

This is funny I also have a Sony z3 compact and have the same issue. It's up and down like a yoyo
I have been talking to the tech team for weeks and all they want to do is check my postcode! Then offer me 20 quid to buy a new phone so I can try my sim in it!
Don't you think it could be lollipop that's the problem here, sounds it to me however no one, not even Sony will take ownership!

If you can get to a Vodafone shop, they can try your SIM in one of their devices.   If that's the problem, they'll also be able to give you a new one.

As this has happened after an update, I'd be inclined to try a factory reset before going down the repair route.   Resetting clears out any bits of old code that are hanging round from the old firmware and may fix the issue.  Don't forget to make sure your contacts and calendar are fully sync'd and back up your content first.   A reset would be part of the repair process, so you won't have lost anything by giving it a try.

FWIW, I always clear recent apps and restart a device before updating, just to do it as cleanly and with as many of its resources as possible.
