Everything works fine on my mt4g then out of the blue the connection just drops. This happens for like 5 minutes then its back to normal. I have full bars plus my other phones are just fine. Sometimes it even says im not connected to a mobile network even though this is already checked in the settings (even tried unchecking ENABLE ALWAYS-ON MOBILE DATA but nothing)..Could my phone be defective? Is anyone else having this issue?

Hi,
I've noticed atleast 4 times that my phone doesn't connect to a mobile network from data when away from a WIFI connection.
So when I'm at home, the phone is connected using WIFI and all works fine. When I leave home, the phone should be connected via a mobile network (i have Settings>Wireless & Networks>Mobile Network set), but it doesnt seem to connect when I try and use the browser. If I restart the phone or unset then set "Mobile Network", then the phone seems to pick up the mobile data connection and function normally.
Has anyone else seen this?
Cheers,
Ash
Sometimes, mine will switch automatically but very often it will not. It hasn't been a problem for me but I agree that it should switch over without us having to manually turn Mobile Network off and then back on again. Anyone have any ideas? I'm using the Bell stock, unlocked on AT&T.
I know this thread was originally started some time ago but I thought there would be others with similar issues as mine and mashed_ash but. Please, post if you have any ideas. Thanks.
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 ?
Ive experienced that my nexus 4 sometimes loses data connection in certain areas, which my old iphone never did there. I can still call but data connection is lost. This doesnt happen with wifi. I then have to go to the APN settings, push on my provider's APN again, even though its already selected, and then it usually starts working again.
Has anyone else experienced this? Im not sure now if i should RMA this device or if its just an android bug.

Alright, this is a frustrating issue that I've been having since day 1 with WhatsApp, and it's not even just SGS4, but with my old SGS too.
Problem:
Phone screen turns off while on WIFI, after a while of inactivity, WIFI still seems to run, but WhatsApp lost connection and takes a long time to reconnect, and usually requires a full restart of WIFI.
This does not happen on 3G for me, it only happens when WIFI is active.
Things tried:
- Turn off 3G entirely, so it only runs on WIFI.
- Reinstall WA
- Restart phone.
- Do a clean install of firmware (on my old SGS).
- Test it out on new phone~ (Brand new SGS4 i9505)
I don't know what's causing this, can anyone please help me figure this out? Let me know if you need more info.
is your router set to "always connected" or does it disconnect after sometime if no data comes in?
maybe i'm wrong but if it's only a wifi problem you maybe should look into your router settings.

Already looked into that.
Weird part is that Skype stays connected perfectly fine, but WhatsApp never does.
Please search a bit, this has been answered just a day ago.

[Q] WhatsApp Issues on GS4
I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
