[Q] 2G not working 3G/4G working - Nexus 5 Q&A, Help & Troubleshooting

Bougt a Nexus 5 32GB D821 in December in England on holiday. When i came back to Norway the 3g/4g network worked fine but I dont get any signal when i switch to 2G.
I live on the coast so sometimes I lose 3G signals and then I have no signals at all.
I have testet the sim card on my old S3 and there it works fine. Since i bought it in England I have no warrenty and no one will fix my phone.
Is it an hardware problem or software problem?

I have my N5 2 days now and I experienced simular issues.
The 4G symbol would come up but when that leaves, probably due to almost no signal, no 3G, edge etc.
I solved mine by switching it to setting - more - mobile networks - preferred network type ---> 3G ... so far so good.
I also had issues with my wifi on my Asus RT-N66U unit. It would be connected but no wifi at all. reconnect and it would work for a couple of minutes too.
I reflashed the firmware of a couple of months ago and no more issues.
Please let us know if it works for you too so we can help others!

g1 network problems. help?????

I really have problem with the g1 network coverage. I am in india and the operator I use is a good one. I get only 2 bars on my phone whereas it is full bars on my another sony ericcsson phone. Out of 100 calls there are 90 call drops. It is like a nightmare for me. Every time I lose network coverage and have to go to operator selection in setting. There I clearly see the network. G1 does'nt connext to network automatically. I have tried everything from reflashing to a wipe. Tried other operator too. No luck. Anybody experiencing same problem? Anybody knowing any solution to the problem. Really bad for me. Please help!!!!!!!!!!!!!
We are the Group of 5 People Owing G1 in Nashik, Maharashtra and almost all operators are running without any Problem in 2G Network.

Problem with 3G

Hello! My OPO had issues with OTA updates (25R specifically) and 3G. I clean installed 38R with no issues, everything went well however the 3G is down or works for a brief moment and then loses connectivity. Neither 2G nor 3G works. I live in Greece (if it helps more about understanding the network problem).
Any help appreciated!

[Q] D6603 POOR RECEPTION Bell Canada GSM

Hi,
I've been using my Xperia Z3 D6603 for about 2 weeks now on the Virgin Mobile (Bell Mobilily) network in Canada and the network reception is horrible. The signal keeps bouncing from 2-3 bars to zero bars wherever I go. My habits have not changed since using an LG G3 which I never experienced signal problems with. I think it's something to do with the phone not being able to connect to GSM and connects to CDMA only. I think this bc when I go to GSM only under network settings it won't connect at all.
What I've tried:
- Installed generic Canadian firmware
- Went to GSM only under network setting, and have NO Signal
- Entered Virgin's APN settings
Does anyone else have any suggestions?? This is such a nice phone and would love to keep if I can get the signal issue fixed.

Ok then it s better to take it to service center to check its hardware
:good:
Oh man, I really hope it's not hardware...
This might be a dumb question, but are you sure you have D6603 and not another variant?

No 2G - radio problem? etc?

Hello everybody,
during summer I subsequently move between the city with 4G and a rural locality where only 2G of my carrier, BitÄ—, is present. There were no problems during the first month (I used Chroma), but after Multirom usage (when kernel is replaced) I get no signal in the rural area. Once I reach 3G/4G-covered are, everything is OK, though.
But there are some mystics about the countryside area - the phone can`t get any signal even of Omnitel (4G) and Tele2 (3G) at all! Every other mobile appliance works fine here, so it`s not a cellular network fault.
I reinstalled stock ROM and radio back in the city, but it gives THE SAME RESULTS in 2G area.
What could be the problem? And which way would be the best to solve it?
Sincerely, thanks
hello same problem for me...
