Are you on 4.4.4r2? I too experienced that problem but not random for me, only occurs after disconnecting call.

Me too ,runnning latest Pa and Franco.....really annoying.
Edit: Tested some other phones,believe it's carrier fault.

Sudden loss of mobile network

Hey guys,
Ever since I got this phone, the mobile network is lost all of a sudden. Need to restart to get the signal back. Even at the same spot it lost.
Anyone facing the same issue and any fixes for the same would be appreciated.

Same thing with me, normally happens when the signal is lost from being out of range. Then signal just doesn't come back unless I reboot.

Same thing here on stock 2.3.2
Reboot gets it back so I don't know what was the original cause. I have just upped to 2.3.4 manually so I will report back if it happens with this new version.
Two days on 2.3.4 (non rooted) and have not noticed the previous problem yet. Does not mean it has gone away yet LOL
(no I didn't post this at 3:00am - I am on GMT +8)
Im still Running 2.3.3, Will be updating soon.

[Q] Galaxy S4 SGH-i337 at&t foxhound rom ...losing data connectivity

Ever since i flashed the Foxhound rom 0.8/0.9 on my S4 i've been randomly dropping Edge/H/H+. Never did this with TW. I have noticed a slight pattern...it drops mostly after i've gotten off a phone call, but other times i'll just glance at it and its gone for no reason. Usually calls for a restart, turning mobile data off and back on does nothing, and airplane mode on and back off sometimes works. Could this be a kernel issue? Using Adam-1.4+, but its done this with KTweaker as well as Faux123. Any ideas?

Signal dropping then coming back

I'm on T-Mobile here in the US. Not sure if anyone else is having issues. I've had my phone since the 6th. Up until yesterday it's all been perfect. Now every now and then the service just drops to "no service" followed by "emergency calls only" then finally comes back to normal. When I have signal, it's good. 4-5 bars. The drops are random. I'm stock + root.
Anyone else having problems?
Same thing is happening with Rogers

Hmmm... I have tried a couple ROMs but none lasted long enough without bugs to notice. I also flashed the stock image again just to be sure and it's still there.
There's an ongoing thread already on XDA:

Also, there is a thread where a rep from Google, Paul, has acknowledged the issue. Please post your issues there for them to track/investigate:

Unlocked, stock rooted, stock kernal, and I'm having the same issues. Very slow when switching from lte to 3g and back to lte, sometimes it doesn't switch back to lte. Also the loss of signal. I though if factory reset back to stock but I guess that's not the issue.

I don't think it's the networks, I think it's the hardware

According to this link:

It's a software issue.. I am getting the same thing on Rogers. I only get it after a call or when sending SMS. Frustrating issue, to put it mildly
I switched to bricked kernel my connections have been solid. Later I also switched to the Cataclysm ROM and so far so good.
I think it is a software issue.

N5 and LTE + Voice

Does anyone else have an issue where the LTE signal is not reestablished after a phone call? I have to reboot my phone to get the LTE signal back, otherwise it remains on HSPA+. I am in an area with full LTE signal (all bars). This is driving me crazy...

When a call gets routed through it uses the HSPA+ or HSPA or EDGE network to handle calls currently LTE does not do this so it may take awhile to reestablish your connection thou lte again
It NEVER reestablishes the connection though, stays on H.

I have no idea then, after about 30 seconds on T-Mobile the LTE returns again after being on H

Have you just tried throwing it in airplane mode for a second to kill the radio and see if it pulls and LTE connection after? I'm on AT&T and every once in awhile I'll have to do that when switching between cell towers while driving.
hmmm... that's strange, you shouldn't have to do anything. mine goes on H during the call, as soon as end the call it immediately (about a second) switches back to LTE. I'm not rooted or anything. everything is stock.
not sure if this will help but try doing factory reset and clear cache and such?
it would be easier if you gave us more details.
Custom ROM? kernel? rooted?
Everything is completely stock, never rooted etc. Seems to be slightly improved today. It has actually come back into LTE a couple times without rebooting. I've also tried the airplane trick a couple times and that has worked on occasion as well. Still hit or miss so I may just RMA it. Appreciate everyone's help!

Don't mean to necro this thread, but just looking for some additional input.
RMAd my device and the new one exhibits the same behavior which leads me to believe it's the network in my area. Anyone ever experience the same thing especially in area with new LTE?

[Q] keeps loosing phone connection

Starting a while ago my phone keeps dropping its connection (every 10 seconds) so it looks like it in airplane mode without the airplane. Empty triangle. Its not the carrier, because the my wife's S4 has the same and no problems.
I thought it could be one of the problems described here, but nothing there fixed it.
Made a screen recording of the problem here.
Has this happened to anyone else? How was it solved? If not, other suggestions?
Are you running stock or rooted or is your phone running custom software?

It started with everything stock. Trying to fix the problem I rooted it. Except for that all is still stock.
