Not sure if this is 8.1 related or not.. But since switching from 8.0 to 8.1 I get significantly less signal in places i know for years ive had nothing but great coverage. and at some points its so bad it switches to 3g and even 3g is a weak signal. WIFI funny enough seems to be the same way?

8.1 issue? Bad Antenna? Bad sim? Any Ideas? Ive had the phone 2 weeks this coming friday 23rd. (Nokia Lumia ICON)

I have the same issues with updated lumia 920 with Three, UK. I used to have 4G in my office and city centre. After the WP 8.1 update, no more 4G, just 3G, or H+ at best. Probably need to contact Three UK...

Hi there I actually work at Tesco mobile technical support, I've seen this issue a couple of times today, unfortunately we're not sure why it happens.

I'll post it here if we get any information through, or how to resolve the issue.
