Connection Problems

Recently when I restarted my phone, the 3G symbol doesn't show. Switched to edge and it appeared then switched to 3G again but now can't even connect. Just shows the 4 bars with no edge/3g symbol.

Flashed anything recently? Maybe you're just in a dead zone. What rom and modem are you running?

I haven't rooted my phone yet. My reception is great but it has just acted like this lately.
Sent from my SGH-T959 using XDA App

In that case I'd say its either local interference or perhaps a malfunction with the nearest cell tower. Either way if you haven't rooted yet and it persists, I'd call T-Mobile.

I can now go to edge but still can't to 3g. Thanks. I'll call them.

Also, make sure you're in a 3G area.

Must be the area as aloneinshadow suggested, unless you have changed settings, such as: use only ........ network, intended for battery save. Sorry I can't be more specific but my current rom does not have that option. I just know that 2.1 has it, if you are on Eclair.

Too much to ask for you to post in one of the other two threads on this subject?

may I ask if your wifi policy is set to "when screen off" might be getting the hand off between cell radio and wifi when reconnecting the mothership

How you check that
Sent from my Nexus S 4G using XDA App

I'm experiencing the same thing. For the past month or so, my signal bars go from Green to Gray and as a result I lose any connection to Google's services. Such as Gmail, Gtalk, Gvoice etc. Every time I see this, I have to login to Gtalk and the bars go green again. But this fix only lasts from a few minutes to a few hours if I'm lucky. I've been on the Google forum reading about this issue since April on T-Mobile and other carriers, and now since a month ago on Sprint.

Yes that's the problem that I have

I had that problem with my HTC Desire. The problem only appears when there's very little space left in RAM or internal memory...

No this sounds like Google having server issues. I'm seeing the same on my phone.

Do you see this happening with 3G, or wifi as well?

See it more on 3g. You thing it can be the gaaps cuz I get it back every time I go to gtalk

This happened on my first nexus 4. Nothing fixed it. Nothing. Hopefully your situation is different. If nothing works, flash back to stock and start the RMA process. Google said it was a hardware failure with mine by the way.

Did your happen when you first got it or after you had it for awhile? And what's the RMA process
Sent from my Nexus 4 using xda app-developers app

The periodic loss of signal was there since day. I still have it on my new one. Others do as well, but one day it went out and never came back on. I believe it was a different issue than just random signal loss. Google said hardware failed in it. You have to contact Google to start an RMA. I'm also not implying that your signal won't come back on at some time either. Personally I would flash everything back to stock. Go to a t mobile store and get a new Sim card and if no signal still then contact Google
Sent from my Nexus 4 using xda premium

Under settings, then data, then mobile networks, then to network operators.
let it search, even if it doesn't find anything or errors.
Then click choose automatically.
If you frequently travel out of 3g/H areas, you need that checked or the phone won't roam from tower to tower. you will get no signal.
Also, if that don't work, you can try clicking on a network it finds, and let it register, your signal may come back.
This is a common problem with those that don't live in big cities or near full strength 3g/h areas.
The phone doesn't handle tower handoffs well. Crappy LG modems.

I'm currently going through the RMA process over virtually the exact same issue. However, I've been running franco's nightlies lately and up until he restored the HSIC/wifi stuff to stock in r154 I was actually experiencing less data drops and rapid tower swapping (constantly going from 3g to H and back rendering consistent data inoperable). *shrug* I feel as if it's something in the hardware on the cusp of failing because sometimes it does it more and sometimes it does it less. It's rather weird. I'm also on T-mobile towers through an MVNO (Straight Talk).

I just cancelled and switched to ATT go phone.
I have RMA'd 2 devices, tried multpie new simcards, relflashed, tried new radios, and nothing worked.
It no longer switches from 3g to H on ATT network.
It stays in H constantly.
Also, no more signal drops or loss of signal.
I have 100% signal all the time now.
The data is a little more expensive, but worth it for the coverage so far.
It's not your phone, it's the tmobile network.

GS4 data very sporadic

My s4 data is bad to kick off and back on. It has done had since I first got it. I have 3_g at home and it's very solid signal, I never lose signal in fact i keep 4-5 bars but data kicks in and out all of the time. My old phone was very solid never lost data signal ever. I have tried the 3 different radios and several ROMs but they all do the same thing? It doesn't show roming and it looks to be on sprint solid. I know I've read about losing data due to flashing but mine works fine then it doesn't work, off and on, off and on all of the time... Rebooting sometimes brings it back, switching radio off will sometimes too but sometimes I just have to walk away for 10-30 min and it'll pop back up... any ideas?

I will assume that you have updated PRL and profile. If not, do so. If that does not solve the issue, call Sprint to see if thry are working on towers in your area.

Yes I did update profile/prl as well. I have a second phone we keep in the house (as my house phone) but it keeps data signal just fine never drops either. I haven't called Sprint I may try that but I really think its buggy firmware
Sent from my SPH-L720 using xda app-developers app

I called Sprint, wasted 10min of my life lol. But I set force cdma, we'll see how that goes. No lte here anyway.. in fact 2g some of the time.. gotta love sprints data (shoot me)
Sent from my SPH-L720 using xda app-developers app

Hope the problem works itself out. One last suggestion would be a factory reset (that is if you didnt wipe data through rom flashes). Doing so can potentially fix a lot of different isses....maybe this as well. Good luck

Force cdma seems to have fixed it. I get lte in town but I live and work outside of town. Guess it was always getting stuck between the two...

Your signal bars reflect your voice signal not data. Download this for real info on what your phone is doing

And check this site for LTE deployment info, you could be getting NV deployed in your area http://s4gru.com/index.php?/forum/39-markets/

4.3 keeps dropping internet connection?

Hi, I've had my nexus 4 for about a month now, when I got the phone I automatically updated to 4.3.
Since the very first day I've had it, it has kept dropping internet connection randomly multiple times everyday? The signal bars will go from blue to grey and stay like that until I either reboot the phone or turn on airplane mode then turn back off again.
Its becoming a constant hassle trying to use the internet because it keeps hanging.
Has anyone else come across this problem? If so what did you do to fix it?
Thanks alot
Sent from my Nexus 4 using XDA Premium 4 mobile app

Do you mean WiFi or carrier data? And how good is your carrier signal? You can try flashing a different baseband.
For WiFi, try turning off Wifi Optimization.

Its the carrier data that keeps dropping, I also get full bars most of the time.

Its surely a baseband problem..nothing to worry..
Just try different basebands and test them and see what works for you,but for that you need to be rooted..
Before you asking or creating a new thread refer to efrants thread for unlocking and rooting.:good:
