[Q] Galaxy S4 persistent connection problems - General Questions and Answers

Hello
I'm suffering connection problems with my S4 for over 3 months now. I've tried everything including switching to Cyanogenmod and back to original, factory resets, other simcards, ....
Sometimes my phone works perfectly and then suddenly I can't receive calls/make calls or send text/receive text messages. the only thing that keeps working is Edge/3G.
When i then try to call someone, it says 'Mobile network not available' although I see my carrier at the bottom of that notifications panel.
The service state says: speech:not in use data:in use or sometimes it says out of service and I have no network at all (except Edge/3G)
When i switch to flight mode and back sometimes the problems are solved for a short while but not always...
I'm desperate to get this solved and I lost my warranty because I flashed Cyanogenmod :/ any ideas?
Thanks

Touch Cruise Cant Receive Calls in Sleep mode

Just got a new Touch Cruise and I just cant seem to receive calls or SMS when the phone is in sleep mode.
I tried putting the 3G off and all data communication off. Still same problem.
Phone works fine when turned on.
After it resumes from sleep mode i can see "No Network" message and immediately reconnects to the network. Signal is only one bar where as in my K-JAM i have no issues. weak
Anyone face similar problem ?
My ROM is 1.28.415.2 wwe 02/22/08
Radio is 1.58.25.14
protocol 25.69.30.05w

What do you mean with sleep mode?
When my phone need to establish connection I need to enter my password.
With respect to your signal, do you refer to G or 3G?
By just pressing the power button once or after the time out in battery mode, the screen is put in sleep mode. I have not set any passwords.
After this I cannot receive any calls or SMS even if i put off all Data Communications, Wifi, 3G, GPRS. When i dial from another phone, I just hear a dead tone and does not go to voicemail either.
When i resume, i can see the message "Service Unavailable" breifly and the phone reconnects to the provider. I can make and receive calls then as long as the phone screen is on.
I have reflashed it twice but the same issue remains.
It is not a network issue as the problem is not there on my K-JAM.
It also can be a hardware flaw... I suggest restore the original ROM, bootloader and take it back...

Think i will do that. It is on the original ROM and the phone is just a day old. Guess it is my bad luck.
I wondered if it is just WM6 problem and required some sort of registry hack to keep connection alive in standby mode or something like that..
Thanks guys.
Gave the Cruise to the dealer Cellucom and they confirmed after 4 days that the board is bad. Got a warranty replacement with the option to take the Tytn II instead. Grabbed it. Guess i have to jump to the Kaiser forum now. Ciao.

[Q] HELP, Phone stuck on Emergency Calls Only

Hi,
I am actually on holiday, and for the first few days my nexus s (running masters deodexed 2.3.3 with voodoo kernel) was working fine. However for the last day and half, it has been stuck on Emergency Calls only. I have tried everything to fix it, switching to airplane mode, full reboot, going into settings, wireless and networks and manually selecting a network but it still only remains in Emergency mode only.
I pressed *#*#4636#*#* and under phone information, GSM service says Emergency Calls Only
I have tried switching off and on the radio and fiddling with the preferred network type but nothing seems to work. I dont know if this is a roaming issue (i dont think it is because it was working fine initially abroad) but any help will be most appreciated.
Thanks,
Hi, I am having this same problem too. I have the Nexus S from Koodo and it seems like it doesn't "like" my simcard. I also have a fido simcard on me and the Nexus S works fine on my Fido simcard. Today i went to a Koodo store and tried another one of the simcards and it didn't work either. So far I think my Nexus S is defective. You can PM me your email if you like if you want to see if i fix it.

[Q] No SMS while on wifi, can't switch from wifi to cellular

My Nexus 5 is running Android 5.0.1 (Lollipop). Unlocked, not rooted. My carrier is Cricket. Here is what happens:
1. If the phone is connected to a WiFi network, I am unable to send text messages. The message will attempt sending for a while and then basically timeout. The app will report that the send failed. This will happen no matter what application I use (Hangouts, Google Messenger, chompSMS...). If I'm on the cellular network, texts send find. EDIT: Actually I'm seeing that's not actually true. Even when I'm on LTE, there's no guarantee messages will send. I can't actually detect a pattern here.
2. I am unable to switch from WiFi to cellular data by turning WiFi off. If I'm on WiFi and I disable Wifi in the Settings panel, the cellular indicator will change to show 2 or 3 bars of service with an exclamation point (!), seemingly indicating that I'm either not on the network or that I don't have data. If I reboot the phone I'll have full LTE.
I first started noticing the issues with text messaging back when I was running CM11 nightlies. Everything was fine and then a few weeks ago it started happening. I figured something had gotten messed up in those builds so I flashed to stock Lollipop but the problem persisted. I flashed to 5.0.1 and the problem remains. I also tried switching carriers from Cricket to T-Mobile, but T-Mobile service was so bad in my area that I had to switch back the next day; I didn't really get a chance to put it through its paces.
I know this is a weird one, so any ideas would be greatly appreciated. Thanks!

S6 not registered on network etc...

Morning all
We have an issue with my wife's S6(UK, stock up to date software, EE network)
A day ago if she tried to make a call and she just got a message stating 'Not registered on network. She's not getting any incoming calls or text messages either. And not able to use mobile data (wi-fi ok)
Tried all of the normal things, restarts, manually selecting network etc. The only thing that solves the issue is to select 2G only in the network settings, then calls and texts are ok, but obviously mobile data is non existent.
We have been though the troubleshooting with EE on the phone, part of this was to try another SIM which did not solve it, so we know the problem is with the phone.
Also done full factory reset last night, did not help at all.
Any ideas apart from sending it for repair, as EE are telling us?
Not wanting to root or modify in any way that is going to void warranty
Thanks in advance

Lost Data Connections

Hello All,
I have this phone for about a week, i have one major issue with Mate 9.
Whenever I send or receive MMS messages, my cellular data connections would stop entirely. My remedy to this issue is switch on and off the flight mode, then everything would resume to normal (but i can't do this all the time). I have tried to reset APN and got a new SIM from my wireless carrier, but no success. Has anyone experienced same issue as mine? How do i resolve this issue? please help!!
same here, phone from Dubai, I am on T-MO
