Hello everyone, I'm experiencing a terrible situation with my OPT - O2 2.1.2.
I used to rely on Intelli3G (an Xposed module that switches mobile radio to 2G when screen is off to save battery and then reverts back to LTE on screen on).
This worked perfectly with OPO but I noticed strange disconnections of the mobile data with no possibility to switch on again without rebooting.
I've studied what happens when the phone is asked to switch to 2G Only:
with the *#*#4636#*#* menu I noticed that the network type says "unknown,unknown" and there's nothing I can do to get things working again until a reboot.
In this situation I see that there's signal, triangle is full, but I'm unreachable.
If I keep my radio to WCDMA preferred (with screen off) or LTE/GSM (while using the phone) everything works fine (so far).
My carrier is Vodafone IT, I already changed my SIM card for I thought I had a faulty one.
Anyone else is experiencing these disconnections?

I'm having similar issues. I can only connect with one SIM at a time. One SIM card only connects via 2G. I think I need to go buy a new phone. I've even restored back to old versions without luck. I've flashed the modem too. No luck. This is bad for someone on the road like me. I'm missing critical calls. I'm back to using two phones as a work around.

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.
Hi all,
Been having some problems recently on my wife's Nexus 3g (tilapia). She had it for about six weeks now, I rooted it and installed PA on it (same as my grouper).
Everything was working fine until recently, 3g stopped working for no reason that I have been able to figure out.
What I've tried and noticed so far:
Clean install (full wipe) of PA, and also tried different custom roms - 3g not working
Tried the simcard from my phone to rule out network errors (since I'm on a different network) - still not working
In notification window, 3g coverage bar shows blue when wifi is on, asa it's turned off, a little H appears next to 3g bar, which straight away goes grey and stays that way until wifi is turned back on (this is all in range of wifi network, 3g icon does the same thing if i move far enough to lose wifi access). Strangely enough the carrier (Telstra) shows on my lockscreen, but any attempts to use the connection, like playstore, browser, go sms, all return a no connection error. Also when wifi is off and 3g icon is greyed out, the device sometimes crashes (hardlock) when trying to unlock the lockscreen (maybe unrelated).
Flashed back to stock following these instructions: http://forum.xda-developers.com/showpost.php?p=32075129&postcount=1 - problem still remains
APN settings have been tried on both auto and manual, no luck.
At this stage I'm starting to think this may be a hardware issue with the 3g modem and thinking of just returning the unit altogether.
Has anyone had anything similar happen?
EDIT I've returned it on warranty
I woke up with my phone (stock 4.3, rooted) having no data (on MetroPCS). After two hours, still nothing. 3G or H shows up with grey bars, but no blue and no data connection. I changed from WCDMA preferred to only. I reset the phone. I flashed the stock 4.2 rom, tried airplane mode, 2G only, and removed sim card - and still nothing. I've been with Solavei since May with my Nexus 4 and switched to MetroPCS in August.
Has this happened before, or did my phone just 'break'?
Any tips? Thanks.
looks like a carrier problem, the radio seems to be working fine
try another sim card
Well, not it's mysteriously working again. Is this most likely a carrier or phone issue? When I called them (didn't mention that before) they had no outage.
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. :,-(
Hello,
my note 4 - n910G recently started acting weird. It would register to the Vodafone AU, but if i try to call, it would show "Not registered to Network"
Also, sometimes everything works fine for like few minutes. 4g, calls, sms, everything sim related works. and then it would stop working again. it will still be connected to the network, but nothing works. the mobile data sign on status bar shows that Sending is green, but Receiving is nothing when this happens.
EDIT: Sometimes it wouldn't register at all too.
I have tried, factory reset, changed sim, and even done Device Initialization from Smart Switch, because for some reason, ODIN with re-partition pit was not deleting the data in the phone.
Thanks in advance.
UPDATE: so I can use 2g all the time. it's only 4g or 3g which is not stable. 4g network gets registered fast, but doesn't work most of the time. 3g takes way too much time to register, and works a for few minutes before going down.
Is it the network cable or something else? please help.
Same with me when I am in low network coverage area. In the same place same sim card works no problem in another phone.
I did:
1. Restart device and switch on/off airplane mode
2. Change different sim cards
3. Factory reset device
4. Installed root and custom rom (LineageOs). Problem first time occured on stock rom, without root, knox 0x0...
I am not sure, since I am first time using Note 4 in this area, but I think problem might happend sincet latest update...
I was thinking to buy S8 or Note 8 but after this I am not sure...
Some more update:
When 4g sometkmes works, it switches off the phone completely and have to replace the battery to turn on the mobile. Cannot just press the power button to turn on the mobile after it switches of

So, did you fixed this bug?? I have same thing time-time.... ((
The issue is because you have a US Carrier variant of the Note 4, which isn't designed to work on GSM networks.
