Xperia Z5C poor signal/calls

[Anonymous]

Hiya,

First post on here as I've never had any issues with my O2 phones in 14 years until my last upgrade.

Upgraded from Xperia Z1 to Z5C in October and from day 1 have had extremely poor signal and call quality. I no longer have a signal in places where I have never had an issue and in places where the coverage checker says there is a strong signal.

I have been into store 3 times, done a factory reset and reinstalled software updates with no change.

I'm getting really frustrated now as I increased my minutes at upgrade and am now not only making a fraction of my required call but they only last a few minutes before cutting out or the call quality dropping (e.g the other end sounding like they are underwater).

The phone hasn't been in water or damaged, I've had the same issue since day 1 but no one in store seems to be able to help.

Any suggestions or should I be looking at asking O2 for a replacement handset.

Thank you in advance

Laura

Have you used the status checker to see if there is a faulty mast near you?

Have you put your o2 sim in another o2 phone to rule out a faulty sim?

@Anonymous Have you checked http://status.o2.co.uk to see if there are any mast problems in your area? Do you know if anyone else on O2 in your area has any problems?

Hi, I have checked the status checker and all is fine on there. I experience the same issues where ever I am though and o travel around the county.
I will find someone with an O2 phone tonorrow to test my sim and report back.
Thanks for the quick replies

Also it might be worth trying a new sim if the other phone doesn't help

Get the phone back to Sony to be checked out - sounds like an antenna fault tbh.
If you have had it less than 28 days (for future reference) you can insist that o2 exchange it, otherwise go to Sony for an investigation.

Do come back & let us know how you get on

Hi, no update but I've dug out my Z1 and just finished updating it. Will use it tomorrow to test the sim.
Thanks again for the replies and I'll report back soon

Update***
Used Z1 today and absolutely brilliant. No signal drop out, normal call service and people I called said quality at their end was better than every call with Z5C.
It must be the phone /antenna as suggested above.
As I'm within 12 month warranty can I use O2 as my legal contract is with them or do I have to go through Sony.
TIA

If it was up to me @Anonymous I would get the phone back to Sony. They are far better placed to fix it than O2 repairers. http://support.sonymobile.com/gb/contactUs/
