Re: XPERIA Z5 Heating up and problem with calls

 Hello.

My z5c used to work fine in earlier OS 7.0.  I did an OTA update to 7.1.1 and then phone started heating up and BASIC TELEPHONY was messed up. Outgoing calls do "nothing...no ring tone..nothing....it gets lost" for 30 seconds(!), on the first attempt, and then call stops. Then it takes a second attempt and HEATING ON MY EAR before it connects. Incoming calls go straight to voicemail. Phone doesn't ring. It takes caller two or three attempts to get my phone to ring on incoming! RIDICULOUS!

 

 

So i backed up my phone, DISABLED MOVIE CREATOR, reboot in "SAFE MODE" etc. NO LUCK.

I tried telephony in SAFE MODE, same probs. NO LUCK.

I did factory reset on 7.1.1. NO LUCK

I downgraded os back to 7.0 (32.3.A.0.376). NO LUCK.

 

HOW IS THIS POSSIBLE.

Re: XPERIA Z5 Heating up and problem with calls

just learnt THIS:

https://support.t-mobile.com/thread/140820

 

don't know if it affects me, but calling (SIMPLE CALLING) should be on the BASIC 2G QUAD BANDS going back to the 1990! Should not affect BASIC CALLING?  

 

The Calling network affects the HEATING is as well b/c if the network is not available, the chip puts out more microwave power to fry your brain!! Wonderful! This is what happens when you have a rubberstamp FCC. Plus this affects battery DRAIN. sound familiar?

Re: XPERIA Z5 Heating up and problem with calls

CONFIRMED: All Xperia users on T-Mobile take note: it wasn't the coincidental android update to 7.1.1; it wasn't Sony's s/w "Movie Creator"; T-Mobile networks are rolling out VoLTE and new bands in major metros. They are jettisoning old 2G for voice in favor of the "Internet of Things" and low latency 5G.

 

Go to Call settings; Change your network preference to "3G preferred/2G" and not "4G preferred/3G" and the call/telephony problem GOES AWAY instantly. But then, on the other hand, streaming youtube vids or video-chatting "goes away" too! SADNESS.
