Hi,
I've been having this problem since stock firmware. 3G works, but ever when I turn it off (with an apn on/off widget, or throught wireless settings), I can't switch it back on most of the times. It says it's switched on, but the 3G notification never shows up and I can't get online. This also happens when I autimatically switch from 3G to Wifi. Only solution is to reboot the phone completely, then I can use 3G again 'til I switch it off or get on wifi again.
Again, I've been having this since stock rom, and now I'm on Valhalla 1.0, still same problem.
Hi,
I'm having a problem switching to 2G when the display is off.
What I expect to happen:
<display switches off>
- 3G is turned off
- 2G is turned on
<display switches back on>
- 2G is turned off
- 3G is turned on
What actually happens:
<display switches off>
- 3G is turned off
<display switches back on>
- 2G is turned on
- 2G is turned off
- 3G is turned on
So it looks like Android somehow can't switch on 2G while the display is off, and delays this until the moment the display comes on again.
As a result the phone is entirely off-line while the display is off.
I tried this first using Tasker and thought Tasker was to blame, but then I tried the 2G Toggle app (https://play.google.com/store/apps/details?id=it.abiondo.app.gautotoggle) and it had exactly the same problem.
So unless this app was created with the Tasker App Factory, the problem doesn't seem to be Tasker related.
Can anyone help me out here?
Device:
HTC One S, rooted, s-on and running CM10. No further mods, no custom kernel.
Thanks.
I'm glad I'm not the only one.
I'm on the stock, rooted, ICS rom and I use the Toggle2G app.
If the same happens on CM, it means it must be something low level and not related to Sense.
Edit: I use Llama instead of tasker, but it's the same.

The strange thing is that loads of people are able to do this, so I wonder whether it's a setting or an app that somehow sabotages this
I've tried on a freshly factory resetted rom, so I would exclude any app interference and any particular setting.
One idea: if we set the event in tasker/Llama so that it not only toggles from 3g to 2g but it also switches off the mobile data connection, and then another event to switch the data connection back on after a few seconds?

Alas, that too doesn't make a difference. I tried two scenarios for the screen-off event:
Mobile data off -> wait 1 minute -> set 2G only -> mobile data on
and
Set 2G only -> mobile data off -> wait 1 minute -> mobile data on
The 2G-only bit is still delayed to the moment the screen comes on again.
But the weird thing is: it worked once, and only once, using the first scenario. How about that? So you must be on to something, but we must be missing something.
I had only tried the second scenario and it didn't work for me either.
About the time it worked for you: could it be a wakelock matter? What if you put a partial wakelock (= cpu wakelock) in the event's actions? If I remember correctly, you can do that with Secure Settings.
I think the problem is CM.. maybe is the annoying connection drop issue! Until now there is no fix for that, someone resolved by flashing newer nightlies, or changing scripts, or flashing radios, but still there isn't a definitive fix...
I fixed by flashing MIUI...
You're right, Secure Settings can do that.
I've tried it just now up to a two-minute CPU-only wakelock. Doesn't work either.

I don't know, I haven't had any problems with connection drops so far. Apart from the occasional spontaneous reboot everything is running smoothly.

I see... I'm out of ideas, for now. Could this be related to the radio? I'm on 1.15 radio.
By the way, it's not related to CM, because I'm on stock (rooted) 4.0.4 and it's the same.
@superbalza: which radio are you on with MIUI? Is it different from what you were using previously?
Thanks
I'm on radio 1.08ts.50.02.16
I'm on the latest 1.15...
Looks like not too many people have this problem...
In the meantime, I created a workaround: I made a Tasker task that first switches to 2G and then locks the device. The whole process of switching to 2G takes about 10 seconds. Then I created a shortcut to that task on the home screen, so I can shutdown with 2G with one click.
Hi, everyone!
So, my Nexus 5 only works when I set it to use 2g network.
Explaining it more clearly: when I set 3g, everything starts to go a little crazy. The phone signal gets lost back working, sometimes it doesn't even recognize the sim card
When I try to access network settings and network operators it gets really slow and sometimes the phone crashes and reinitiates.
I've tried setting a new rom and I am running the most recent version of Cataclysm right now. I've tried changing the phone modem driver too (actually I think I have just reinstalled it) and nothing.
Interesting thing is: sometimes when I turn 4g on, the internet signal works, but when I try to make a call, the signal gets lost and it appears a "turn off airplane mode" pop up.
That's it, guys. Thanks in advance for any help you can give to me and I'm sorry for any english mistakes...not my native tongue.
Hello guys, I've been trying to find a way to force 4g only on my samsung SM-GT920F ( using the lastest version of everything);
I found about *#*#4636#*#*, which doesn't do anything, I found some app that will get me into the testing mode or whatever the name is but the app either crash or give me this imgur.com/aNgCDY2
Don't mind the screenshot, I actually get around 3bars of 4G+ but for it switch to 3g for a few second everytime so I'd like to force it to be 4g, thanks you!
I think the problem would be that every time you call, it switches to 3G/2G for better connection. Unless you have VoLTE (I think), you might not be able to.
Just wondering if anyone knows of a viable alternative for A.S.S. ?, seriously though that app allowed me to lock my data connection to whatever band I wanted on my note 4 and I can't get it to work with the v20 is really annoying at work it constantly jumps between LTE and 2g
Yeah, I have the same problem with the connection, it's really frustrating T_T
I agree as well. I'm constantly dropping my LTE to lower speeds. Sometimes I put my phone in airplane mode then turn it off just to get it to jump back to LTE and stay, annoying is not the word.
I saw someone in a different thread who found a way to do this on Sprint in one of the hidden menus. I don't remember exactly how, but IIRC it was a testing menu they found with Shortcut Master
So I found it, just search "band" and it's the first one in the list. Dunno how long it lasts though, I might change every time you switch towers.
