Xperia z3 compact Losing mobile data connection

[M8ken]

Hi,

I recently received my sony xperia z3 compact and have noticed that after it has been connected to wifi for a long time and then goes out of wifi range it doesnt seem to automatically revert to mobile data and the only wat to get it back seem to be to restart my phone? Im on the 3 network, does anyone else have this issue or know if its related to phone or network or have a fix?

thanks

I had the same issue and had to send the phone back for a refund. Also on Three UK funnily enough. My issue seemed to be related to using Bluetooth. Such a shame as I loved the phone.

Same here..

It's either wi-fi or bluetooth related.

Hey Sony, any fix?

Did anyone find a solution (apart from sending the phone back) to this issue?

Issue:

Mobile data signal is lost and does not return unless phone is shutdown or restarted

Background:

Sony Xperia Z3 compact

Three mobile network

long train commute each day (where the issue occurs most frequently)

stamina mode is off

So far i have tried the following:

1. turned off Wi-Fi - no difference mobile data signal will be lost and not return at least once per day
2. turned off Bluetooth - no difference
3. turned off 4g - no difference
4. changed 'preferred network mode' to WCDMA only - Managed to get three days without the issue occurring

Anyone else had the problem or any kind of resolution?

Regards

Pete,

Thats pretty much the same as me. I noticed it mainly on the train never had good reception on the train with previous Iphone 5 due to network but definitely seems to be more of an issue with the sony I hope its just a network related issue or software update required and not the phone!! Have you managed to find out anythng further, I dont know if this is an issue known to Sony or three??

thanks,

Mark

Hi Mark,

I raised a support ticket with Sony. They have advised that they suspect it is the phone. Suggested steps for fix are to run a PC Companion repair on the phone. As that is a destructive process I'm not sure this is a good idea as 5.0 lollipop is out very soon. So i think I will wait for the 5.0 update before trying to fix mine (assuming that the issue is related to the phone's software as suggested by Sony)

Yesterday however it cut the mobile data connection 5 times on the way home! Luckily the Z3 compact restarts quite quickly.....

I will update if i have any further progress as I am not keen on getting rid of this handset or my tariff with three.

If you get anywhere please let me know.

Regards

Pete

Pete, I ran a repair on mine and it didn't make a difference so I think waiting for a firmware update is definitely the best bet.

I am on Three with the 5833 model compact.I have not had the data drop off but quite often will not fire up when out of wifi range.I then have to restart to recover the data connection as mentioned.

Thanks for the responses everybody. Hopefully the upgrade to 5.0 will resolve these issues (if they are related to the handset and not the network).

I will of course keep this thread updated with progress. If anyone else gets anywhere with this issue please post here so we keep the thread going.

Many thanks

Pete
