4G Problems with D802 (3 UK)
Had a Nexus5 that performed flawlessly on 4G, but wanted/needed the extra battery of the G2.
Bought an unlocked new D820 G2 from Ebay UK. Phone is great except for 4G.
Firstly, it defaults to GSM/WCDMA. I can change it to GSM/WCDMA/LTE auto, but every reboot will reset it to GSM/WCDMA only.
Secondly, when connected to 4G, any incoming call goes direct to voicemail.
Thirdly, when on 4G and making a call, it first drops to H/3G, then loses all mobile internet, and when the call starts to dial out, reconnects to H/3G (but never 4G). Afaik, the D802 G2 should support SVLTE?
I can get into the service menu, but when clicking LTE-Only I get "not supported".
Any ideas what the hell is going on?
The software version, baseband version and firmware version all check out as being UK/up to date - and the phone hasn't been rooted or tinkered with. The SIM is the same 4G SIM that worked fine on the N5
