Z3 compact not automatically re-connecting to network

gr33ngav — Sun, 25 Jan 2015 16:17:13 GMT

When I lose cellular signal my Z3 compact fails to automatically reestablish a signal when I move into an area of improved signal, instead it shows the red cross against my signal bars and i have to manually restart the phone to get data and celluar signal back.

This is really irritating because if I don't notice, all incoming calls are diverted to voicemail!

Having had a google around the area it seems to be a common problem but I can't seem to find a fix for it anywhere. Does anyone have a fix or work around?

What network mode are you using? Try WCDMA(preferred)/GSM. Like that,it will try to find 3G but if it cannot,it will go for 2G.

I only have the options of 4g down to 2g there is no option for WCDMA.

Could you post a screenshot? You should have LTE/WCDMA/GSM,all these.

I think I'm looking in the right place, mobile networks > network mode. And it just lists 4g preferred 3g,2g then 3g preferred 2g, down to just 2g

Besides, if I'm paying for 4g I'd like to use it. I was hoping this is a firmware problem as I really don't want to have to return the phone to the shop 😞

And what is selected? You should contact your network.

I have the 4g(preferred) 3g/2g selected. This is the same SIM that I used for my previous phone and had no problems. As I said in the OP, this seems to be a relrelativly common problem with Z3s.

I will give the 3g(preferred) option a try today and see how that goes, thanks for help.

No such luck I'm afraid, dropped signal twice this morning already hopefully the o2 shop will take it back as I've only had the phone just over 2 weeks.

Take the device back,explain the issue.

Thanks for your help, I explained the problem over the phone and they seem to think a SIM swap should sort it. I'm sceptical but we will see.

Tell us if it works.

Had the sim card replaced and so far so good. No signal drops the past 24 hours, I'll post again if that changes.

Had same trouble. All or nothing reception bars. Scheduled messages not sending. Calls and messages not coming through.

Dropped from 4G and now get reception, seems to be holding. Reception bars vary from three to four which seems more realistic(?) than all or nothing.

Hopefully this means the phone doesn't heat up so much, and that I can finally get at least a full day of battery life; these were other issues I've been having.

Doesn't seem like a fair solution though, to just drop off the 4G network.

I find myself wanting to go back to using my cheap old Samsung - it was 3G and reliable - not the way you want to feel with a shiny new piece of tech in your hand.
