Hey!
I have found a really weird issue since (officially) updating to lollipop (N910C, BOC3). Initially, mobile data worked fine, but after a day or two I noticed, that after going off of wifi, I only got edge connection. I rechecked the settings, restarted the phone but the phone just doesn't go past edge (to 3g or hsdpa; no lte yet for me).
So I then chose to hard reset my phone, wipe cache and reinstall everything. At first, everything went fine and I had H+ connection, no problem. I tried to enable/disable wifi and mobile data a couple of times, but all seemed fine. Today (after 1 day), I noticed again that mobile data is stuck on EDGE.
As far as I remember, everything worked fine on 4.4.4. I even rechecked my sim and settings on my old XperiaZ, where H+ works normally.
Any ideas?
Best regards and ty.
Update: After messing around, I found that by setting the network to wcdma only, allowed the phone to connect to 3g. This means that when left on automatic network mode, the phone choses 2g network and won't switch to 3g even if it is available... Do you guys know a setting where you can tell it to preferentially chose 3g, while on the auto network mode? P.S. I don't have any battery saving options turned on...
Bump... No one knows how to set preferred connection type?
Are you in a room when you are testing? Have you tried to go outside, and while you are connected to edge or H/H+ , open up your internet browser and go to a website and watch your connection if it changes to LTE or 4G...
There is an app that can do what you are asking but you have to root your device in order for it to work... I can't remeber what it's called and I know someone will chime in...

Thanks for your suggestion. I am not rooted yet and will try to keep it that way for a little while yet... will see how long i'll last xD
Manual mode will have to suffice for now, seeing as rooting is the only option. Might be a carrier setting related problem =/

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 everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
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.

Hi,
I have a SM-N910H and since months i have an issue with my 3G and network connection.
When i set the network to automatic 2G/3G, the phone can't recognize my network and i have a message telling that i'm not registrated on the network, and when people called me the phone rings for them but for the Note nothing happens. When i switch to 2G, the phone works perfectly and i can connect on EDGE :crying:.
i've reset the phone many times and update it with the latest ones but nothing happens.
has anyone faced the same issue?
If i root the phone and put a custom rom can solve the issue?
i love so much my Note so i don't want to loose it.
Thanks in advance.
