Several times a day, my phone goes into "silently lost connection" state. When it's in this state, the WiFi internet works fine, mobile internet works, phone still shows good signal bar. Basically, you have no way of knowing something is wrong with your phone, everything is as it should be.
However, in this state, I don't receive any TEXTS or CALLS. If someone calls, it goes straight to my voicemail. If someone sends a text, it goes on my "texts to receive" backlog or something.
The only fix is, go on airplane mode on/off. Then I get the connection back, texts in the backlog starts coming in, calls are received, etc.
My phone is SM-G935F (Android: 7.0, Baseband: G935FXXU2DRB6). I'm on T-Mobile network. I've tried a connection booster app that re-connects to mobile internet network or something, but that's not the problem because I can access the internet at all times, so that didn't work.
Does any know what's going on? Any idea for a solution? Maybe an app that turns airplane mode off and on every 10 minutes or something?

Hi all,
I've got my HD 2 for a week now and everything seems to be working fine, except for a very important bit: the phone.
When I'm connected to the network with a data connection, incoming calls are not possible after some time. The caller just gets a busy signal or my voicemail. This also happens when I haven't been actively using the connection for some time. Calling is also impossible most of the times this occurs, very annoying! Anyone else got this problem? It only happens when a data connection is present, under phone only use there is no issue.
When you say "data connection" do you mean Bluetooth, USB, or HSDPA/3G etc?
I haven't noticed this myself while connected to HSDPA...must check it out.
It only happens when I'm using 3G/HSDPA.
True
I have same problem.
Sometimes the call completely lost and sometimes the message "cannot dial for ...." pops up.
I think it could be connected to network itself ...
I'm on T mobile with a dhd and my phone keeps losing the data connection.
I have to reboot to initialise it again. If I switch to wifi thats fine, but 3G data keeps dropping out. It can't be the network as the reboot seems to sort it. Sim works fine in other phones. Have you got this problem too?
I'm also getting the reboot problem and the dialer crashes too everyday preventing me from making a call. Otherwise a really good phone!
yep, I am having the same problem on my sim, wierd, I had never had this problem. It started today when i turned my data connection (mobile internet connection) on and did not turn it off, usually I turn mobile network (for internet ) on and then off after some use.
I will try to do same for 2-3 days, lets see what happens. Anybody else having same problem. any solutions ?
I can receive calls when the wifi is off, when I turn it on it can't receive calls any more. The wifi works fine and I can use the internet. It shows 3g signal but not the H that shows it is connected to mobile data and all calls just go to voicemail. When I turn the wifi off the wifi data connects straight away and I can receive calls again.
Is there any way to fix this?
Thanks
If it helps I am using the latest Carphone warehouse 2.1 rom.
I have a strange problem on G2. Somehow sporadically data network gets disabled, phone radio stays on. The only way to get data back is toggle data enabled in settings.
What could be wrong with the device?
Thanks!
Are you rooted? If so, what ROM/Radio?
If not, have you selected to make sure your APN settings are correct? Does this happen on 3G only, or does it happen on EDGE too? Could be any number of issues.
I had this several times last week. The data connection was dropping and where it normally would have just reconnected it wasn't. I had to re-enable it in the settings. Voice and text were fine. Didn't try it over a reboot.
I put it down to the network issues, the service status page was showing data issues in my area. I guess when it tries to start a data session it gets a deny back so stops trying and disables data. Underneath I think its a PPP session a bit like dial up internet.
Not rooted.
It happens only with 3G. Never seen data dropping on 2G/Edge.
It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.
