Today my HD has stopped connecting to my network provider and just spends all its time searching for a signal. The phone radio is turned on, but it doesn't seem to find anything. It isn't a problem with the network provider (O2) as my other handset on that network picks up a signal just fine.
The sim card from my other phone doesn't seem to work in my HD either
Any suggestions as to what might be causing this?
Many thanks

PS a hard reset hasn't helped either

December 2011 to Late June 2011
Phone is working great. It was initially rooted with Visionary+, then with the gfree method. I've tired lots of different ROMS and kernels. I get 3-4 bars consistently at my house, and I get 4-5mb downloads.
Late June 2011 to Late July 2011
Annual, four-week trip to visit the in-laws in Sweden. My T-Mobile SIM card worked while roaming (and have data turned off), Wi-Fi calling works great. Phone is unlocked, so I used both our PAYG phone SIM card (through Telenor) as well as a PAYG data SIM card (through Telia). Both worked great.
However, closer towards the end of the trip, I noticed that whenever I had my T-Mobile SIM card installed, it wouldn't pick up a roaming signal (only wifi), and Wi-Fi calling was iffy at best even next to the wireless router. However, the PAYG data SIM card worked great throughout the whole trip, so I didn't think much about it.
On the final day in Stockholm, I realized that I left my T-Mobile SIM card back at the in-laws house. I would just get a new one when I get back.
Present Day
On Wednesday (7/27), I go to the T-Mobile store, and I get a new SIM card. I turn the phone on, I receive a few text messages immediately, deem it good and leave. However, while driving home, I notice that I can't make any phone calls. That is because I have 0 bars (but it is not x'd out). I also have zero indication of data (not even E).
When I rebooted the phone, I will get 1 bar starting out (and I can receive text messages during that time), but then it drops back to 0 bars after about a minute. As soon as I got home, it picked up the wi-fi signal, enabled wi-fi calling, and I got the "Welcome to T-Mobile" text message (since I got a new SIM card). I turned off wi-fi, rebooted countless times, and I got 0 bars every time. Troubleshooting with T-Mobile didn't lead to better results (one suggestion was to switch to EDGE-only connection--it worked for a while, but eventually stopped). Eventually, the wi-fi stopped working, too (even after rebooting the wireless router, and while other computers were using it just fine).
Yesterday (7/28), I eventually find some time to go back to the T-Mobile store and ask for another SIM card. This time, I hang out for a few minutes. I actually get 4 bars and a 4G signal--for a while. It drops back down to 0 bars. The employee taps around for a while. One interesting thing he found was that the option to "use 2G networks only" is always checked every time you to the Mobile Networks setting page--even after you uncheck the option and exit. I tell the employee I will reinstall the ROM, kernel, and radio. Those solutions help maintain a signal for a while, but it doesn't fix it.
This morning (7/29), I have been trying out different radios. I have tried out 2.09.1800.1, but it provided the same results (1-2 bars consistently when I have been getting 3-4 bars before). Now I'm on the stock radio (1.17.531.2). It seems to work okay, but it seems to drop to 0 bars every once in a while. It has also been very difficult to get a 4G signal. If I get a 4G signal, it drops to 0 bars; if it switches to EDGE, I get 4 bars.
Conclusions
I have a feeling that my phone is slowly failing. Are there any other tips I can try?
Thanks in advance, and thanks for reading.
Just call for a replacement

Hey,
so today I noticed my N4 couldn't get any telephone signal whatsoever. At first I thought the provider was just having issues but when I came home and tested my other phone it worked fine, so it's an issue with my N4.
Did a factory reset, problem remained. Then I tried activating 2G only and all of sudden the signal was back, telephone and data on 2G and everything works fine.
As soon as I uncheck 2G only however, both signals are gone and here's the kicker: even when wifi is activated and connected I get no signal. (with 2G+wifi I do however)
Had faux' kernel installed on stock deodexed, wen't back to stock kernel for now, didn't change anything else lately, problem just randomly appeared.
EDIT: nevermind, I just realized I checked 2G only on the other phone as well and forgot about it. Same problem there. Has to be a provider issue.
Got my Oneplus two yesterday. Although I'm extremely happy with the phone I have this teething problem.
Once I updated right away and kept the sim in I got the 3G signal as there is no 4G where I live. Now everything works OK except the data. Once I switch on the data it works for about 30 seconds and stops although the H sign is still there. I have tried manually entering the APN and the problem still persists. Network is not a problem because same sim in my old phone gives continuos data in 3G. Strangely 2G data works with no problems!
In the forum one plus one had same problems but no direct solutions. Is this a recurring problem? Should I return the phone or replace?
Hi All,
First time poster with an unusual problem. I live in Australia and have a Samsung Galaxy S5 SM-G900F which is the European model. Up and till recently I was getting Telstra 4G reception. Now all of a sudden I'm only getting constant 3G reception. I have confirmed that there are no 4G network repair/maintenance/upgrade issues in my area. It was only in the last week that I noticed the constant 3G reception so I can't really pinpoint a specific incident or exact date as to when it actually started happening. Here is what I have tried thus far:
Phone restarts, changing network settings and switching to flight mode.
I've confirmed that the phone network is set to LTE/WCDMA/GSM (auto connect).
I have done numerous hard resets, cache wipes, Dalvik cache wipes, drive wipes, etc.
I have rooted and unrooted the phone numerous times.
I have tried several different stock and custom ROMS.
I have tried 4G SIM cards from other phones.
Tried numerous network switching apps.
NOTHING WORKS!
I always love to tinker with my phone so I'm always looking for ways to improve the phone's performance. It may be that an app (battery improvement/tweaking type apps) I installed somehow changed the network settings but I would have thought a million hard resets would have sorted that all out but apparently not. At the moment I'm running a rooted stock Android 5.1 ROM. I've tried stock Android 4 and 6 as well with no joy.
Here is the unusual thing. When I put in another 4G SIM card into my phone the network still remains on 3G but as soon as I put my SIM card back in 4G magically reappears. It's bizarre. At least I know my phone can still get 4G. You would think that would solve the problem but it doesn't. When I am in an area where the 4G signal is weak the stronger 3G signal kicks in as it is supposed to. When I get back into an area with strong 4G reception the phone remains stuck on 3G and no matter what I do it won't go back to 4G unless I go through the convoluted process described above.
I am all out of ideas. I think I have tried everything possible. I've trawled the web and I appear to be the only person in the world with this problem. I don't know if it is a software or hardware problem with my phone. My SIM card works in other 4G phones so I don't think it is part of the problem. At the end of the day it's not a big deal as 3G is fine but I'm just one of these people that has to fix a problem. Worst case scenario I'll probably upgrade the phone in the next 6 months.
Any suggestions or tips other than what I have listed above would be greatly appreciated. Thanks in advance.
