Hello all.

After the recent updates to firmware 6.0.1 phone got a strange ailments - in my town is a very good range of LTE - the signal icon showed almost half or full range of LTE (Lollipop). After the update is a problem - the range of "zero bars,one bar, two bar sometimes" in the places where he was always full. Additionally, a few times using internet on the phone the internet was disconnect and the phone completely lost coverage.

After a while you have to turn the phone on again or turn on airplane mode. Earlier on Lollipop nothing for a year it did not happen.

Have any of you noticed a very large deterioration of the network signal and its disappearance?

The phone was formatted and the software uploaded 2 times.

How do I report these errors to Sony?

BTW - sorry for my EN

I've got similar problems.
I updated my M4 Aqua yesterday via xperia companion. After the update i have zero net coverage. sometimes the SIM card can't be detected, sometimes i have full coverage, but any attempt to do a call or send an sms or to use mobile internet fails. My phone got rendered useless. i tried different working SIM cards to make sure it is not a provider problem.
I even did the repair via xperia companion, but with no afford....

Sony Team, please help us.

Unfortunately this morning the phone with a full range of LTE signal momentarily lost for no reason. I would add that I stood 15 minutes in one place where the phone was showing all the time full signal.

also I checked the sim card three networks - the same symptoms

I think today I come back to Lollipop. Android 6.0 with current errors is useless and annoying.

For years, I use the Sony and I am surprised how hopeless the software created.

I installed again 5.0 Lollipop and all the problems with the signal network and microphone disappeared.

Yes. I have more problems with signal dropping out and seems to take a while to initialise SIM card on reboot now. I think I'll try downgrading

I also downgraded to 5.0 from 6.1

Everything works properly with 5.0

I think the best software version is what the phone came with originaly

I also got the same problem, i always thought it was the network problem. I ask the people here in the house if they have a signal, since all of us have the same network provider; to my dismay they have signal and i don`t have. I hope there is a solution i find some on the interner but none of them works!
