I have an S5 that when next to 3 other phones in my house receives no signal (data or cell). I have to walk completely outside and its still spotty. Could it have bad antennas? and if so is it just the wire antennas or is there another piece that receives signals?
Past history: stopped using this phone probably 8-12 months ago because of this problem and now just did a factory reboot and re register on the network. and up until the factory reboot the phone wouldn't even register itself on any network or connect to any service even though it showed signal bars. It would either start to make a call and long pause and hang up or just go straight to an "emergency calls only" pop up. When looking on the about phone and status page there wee no registration on the status page.

so here i go
i have just received my jasjar from SBE after them having it for over two month (complete morons over there dont EVER use then unless you are obliged to). got it back, worked fine for a week and now, it will ONLY log on to UMTS networks for example im sitting at home i have a U symbol and 2 bars signal strength. I go into phone settings and select GSM instead of auto and it stays searching for 10 minutes then says no signal, i can get it to join the network if i select manually my network but i can then make no calls or texts or log on to the gprs network. i am using pocket phone thingy for the today screen. and here comes the wierd part. when im out of signal in a non umts area the today screen plug in reports a signal strength ie 63% and above it it states attempting voice connection. and HERE THE REALLY WEIRD PART. i still receive my cell broadcasts when out of gsm signal. ie its searching and ill get a 'text' saying 0208, 01829 .
Please help and dont tell me i have to send it back to the idiots at SBE
Hello
I searched and searched for this issue and i can't seem to solve it on my N9005
The phone has the following behavior (controlled with GSM Signal Monitoring app):
While not touching the phone
Full or Medium Signal
Suddenly No Signal or Emergency Call only
After some seconds (or in some cases minutes) Full or Medium Signal again
This can happen several times within minutes or a few hours without happening
While trying to make a phone Call:
Full or Medium Signal
I press CALL
Immediately No Signal or Emergency Call only
Signal comes back
I press CALL
Immediately No Signal or Emergency Call only
This happened sometimes 5 times in a row, other times i can just make a call normally. Technichal support say they don't even have logs of the missed attempts.
What i did already:
Asked for second Sim card - same issue
Installed several TW Legit roms - same issue
Installed several CM12.1 roms - same issue
Imei is ok, EFS is ok (i think)
One strange thing i saw was that GSM Signal Monitoring only "Sees" me connected to one antenna.
When i placed my Sim card in another phone the app logs me always connected to 2 or 3 antennas at the same time.
Update 1: Also, something I just noticed, since this started happening I don't remember seeing the 3g symbol while browsing the internet. It's either edge, hspa or lte, never 3g, which was my usual connection speed.
Update 2: I inserted a different provider sim in my phone and it connects in umts
Update 3: my sim works without connection drops in a gsm only phone
Does anyone know what is going on? Thanks!
N9005 have very bad modem.....
Just posting this in case somebody has some ideas. I've had a MetroPCS LG Leon LTE (MS345) for over a year without problems, but now it started losing its mobile connection sporadically, for a few minutes or a few hours, as if there was no SIM in the phone.
Symptoms:
The 4G indicator disappears from the notification bar (signal strength indicator shows good signal).
The lock screen says "Searchng..."
Calls fail with the "Emergency Calls Only" message
SMS won't send
I get a "Service Unavailable" error when I choose Settings/Call/Additional Settings
WiFi is unaffected (and WiFi calling seems to work, though it has always been hit or miss)
Things I've already tried:
Checked relevant settings, APNs, etc
Checked the contacts on the SIM socket, all looks good.
Reset Phone to factory defaults
Replaced SIM (MetroPCS did this for free)
New phones are relatively cheap, but I don't have a burning desire to upgrade, so I'm hoping for another option.
I'm having this same problem. I left for an area with no service and came back to an area with service to find that my phone will constantly state Emergency Calls Only and no service. Does anyone have any suggestions?
So i bought a second hand galaxy alpha phone. It was perfect in shape, no scratches or anything, meaning the phone was ell maintained.
The problem comes when im over LTE(4g) network. I try placing a call, it waits like 45 seconds and then it drops. i try calling for the second time and then after a couple seconds the signal drops to EDGE and start calling. after the call it stays a EDGE forever, unless I dial *#*#4636#*#* --->phone information--> set preferred network type: "LTE Only",....once signal shows LTE i can get it back to "LTE/CDMA/UMTS auto (PRL)" mode and keep surfing internet with 4g speeds.
Another related issue, if someone tries to call me when im over LTE, the phone doesn show any incoming call, but to the person calling, the call rings normally. So i dont get calls :S
I though it was a software related issue, so i rooted it and upgraded to andorid 7.1.2 lineage. but still the problem is the same. what shoud i do, i searched the internet and the answer is nowhere to be found nobody has this problem either
I use MVNOs because I am on a tight budget. With MintSim and MetroPCS which use T-mobile I had a below average signal on this phone and with Boost which uses Sprint I had a dreadful signal. Currently I'm using a Verizon MVNO which has an excellent signal except for one issue. The signal will be great for a day then it will become poor. The signal strength will not return to previous strength unless I power the phone down for a minute and then turn it back on. Then the signal will be great for about a day again until it goes bad and I have to turn the phone off and on again.
I tried a factory reset which didn't help. Toggling airplane mode on and off doesn't help. Rebooting the phone instead of powering off doesn't help. Changing the preferred network type in settings doesn't help.
If I type *#*#4636#*#* and change the network from LTE/CDMD/UMTS (Auto PRL) to one where LTE is replaced by a different network and then switch back to LTE/CDMA/UMTS that restores the strong LTE signal but powering the phone on and off is faster.
I could change the APN settings with T-Mobile but with Verizon the APN settings are greyed out and there is no way to edit the current APN or add a new one.
Mobile Data Always Active is already enabled in developer options.
Does anybody know what I could do so the Verizon network strength doesn't eventually drop requiring shutting the phone off and turning it back on to refresh the network connection?
I have owned a lot of phones over the years but never one with signal issues like the PH-1. Essential support won't help because they escalated my ticket to RMA when I was still on T-Mobile. Since an RMA would provide me with a refurbished phone that somebody else probably returned due to the signal strength issues I would rather figure out how to get my current phone to work right with Verizon if that's possible.
When I went out I had no data despite the signal meter showing a strong signal. It turned out my phone had the wrong APN (Verizon instead of Trac Wireless) but unlike GSM carriers the APN settings are locked so TotalWireless (which is owned by Trac Phone) had to send my phone the correct APN. My data actually works now and so far the signal has been very strong but it's too early to say if the same signal problem I wrote about will pop up again since the APN was only corrected a few hours ago.
If nobody else has experienced a similar issue with the quality of the Verizon signal losing strength after the phone has been asleep for an extended period of time then maybe my phone is defective after all. I guess I'll just keep my fingers crossed that the signal still looks good when I wake up tomorrow.
