I picked my phone up from my local Samsung Repair Centre last weekend and my phone signal has been very poor since. Is it possible something else could have been disturbed during a camera repair? I'm having trouble just sending texts, let alone browse the web, the majority of times I look at my phone it's either 'Emergency Calls Only', or no network at all.
I had my SIM card in a Nexus 4 whilst waiting for the S6 to come back, could poor signal be on the Network side due to this switch? Is there any way to test possible causes, any useful apps for troubleshooting?
Hi,
When i got my S6 i had very poor reception. The solution for me was to switch from 4g to 3g. Settings-Mobile Networks-Network Mode-switch to 3G/2G (auto connect). Now i don't have 4g but i have full signal. I hope this helps.

My S2 plus loses signal, data and no able to call and eferything. After restart ok for couple hours and then again. What can I do?please respond.
Reset to your phone..if that doesn't do the job ,just flash new firmware. If still doesn't work,send back to service center
I would recommend you send to service center.
On second thought,better check whats wrong with ur sim card.i think the problem start from there.pull it out and clean the contact point a bit,or switch other sim
Yeah, it can be the fw. After I had my motherboard replaced it wasn't picking up any signal at all. got at a friends place on the 9th floor to see that it caught 1 operator out of the main ones. Thought they didn't plug the antenna or something, send it back in only to receive it reflashed and nothing else.(the repair course stated something like: no damage fount, reseted settings). Guessing they just flashed England's FW and the bands didn't work well.
I had something like this when i had gsm/wcdma connection type (dunno how to it right in english). Where i live there is poor 3g connection and sometimes when phone loses 3g connection and should switch to 2g it does not and simply says no signal. I switched to gsm only for a while (should get better area coverage later) and i don't lose my signal anymore. If it is crucial to have 3g you can switch on and off airplane mode and you signal will be back, at least it was for me.
Hello,
so I got my nexus 5 a couple days a go, and it's my first LTE phone. In my apartment I do not have the best cell reception on LTE or 3G but thats not my problem. My phone is switching from LTE and 3G quite often. I wouldn't care about that except that once it decides to switch it seems to drop the one connection and then take 30 seconds + to get the other one, so I have missed several calls because of it.
it's not the biggest deal, because I will just disable LTE when I am connected to my home wifi, but I am wondering if this could be a hardware hardware problem that I should call google about or a software problem that I could fix/wait for fix.
Thanks in advance!

I have noticed my nexus 5 drops to 3g when sending or receiving SMS. I am probably wrong, but the phone could also be switching off LTE to save on battery but connecting back to LTE for background data sync.
Same here on the signal change upon receiving SMS and email (exchange). I am now dropping calls more often on this device vs note 3 when either SMS or email arrives.

Hi i have a nexus 5 android 6.0.1 and whenever I make or receive a call the network drops from LTE to 3G to Edge. It stays on Edge even after the call has been ended and the only way to goes back to LTE is when the phone is locked for a few minutes. I checked the settings number cellular networks -> preferred network type and its on LTE. I have done a complete wipe on the phone twice and still the same issue.
Also in the past I have another issue which was resolved and I have had this phone for about 2.5 years and after the first 6months the sim was unreadable. The person I got it fixed from stated that the guy I bought the phone off reported it stolen and the only to use it was to switch the motherboard. Im not sure if they are related .
The main issue the network dropping down to Edge is causing is when I drive for uber and passengers call me sometimes I cannot start the trip or load the gps for a few minutes .
This is because of CSFB functionality. LTE is used only for data connection and if you receive or place a CS voice call, then the phone switch to 3G or 2G (depends from signal strenght) to make a call and after that if signal is strong enough switch back to LTE.
Hi,
I am not sure whether is this Andorid-related, Samsung modem HW related, or even my ISP host related. Well, let me describe and then move on.
I notice when I am abroad, roaming, that when I go into low signal area and ROAMING (foreign operator) signal is lost, then my phone does not recover back ONLINE when I get back to area with excellent signal. In such situations my phone number will be unavailable even for whole day, if I do not notice. Very annoying, because I need to constantly pull out my glasses to see that tiny signal icon, check signal, whether I ma online or not, and if not, reset. Or use workaround instead of reset, to turn airplane mode ON then back OFF to reset signal, and voila, I am accessible again for calls and messaging.
What I tired already:
first, I checked with my wife, she has LG G7 smartphone AND she is subscribed with another ISP, and she does NOT have any similar problems. we are traveling together to those areas without signal and back to civilization.
then I sent my Samsung Galaxy S10 to service, and of course, they did not find any problems
then I changed my SIM card for new one, but no difference
then I got angry and bought new Samsung S21 Ultra...but first trip abroad, roaming + to areas without singal, same issue again, only me, my wife no problems
So... any idea?
Is it Samsung, my ISP operator (like, maybe they have some weird roaming algos?), or Andorid 10 and 11 bug?
S21 ultra is a terrible phone, it does take nice photos though

s21 poor signal strength
I've just upgraded to the s21 from the s10. Problem is that I now only get 1 bar showing on the signal strength most of the time (including home). On the s10 it was on 3 bars most of the time using the same network and SIM. If I swap the SIM card back to the s10 I get 3 bars showing again I...

Hello,
i had small software update August 29,
Galaxy S22 Ultra (SM-S908B),
since then i keep loosing mobile data and wifi signal.
I got new Sim card and I did factory reset, but issues are still here. Turning off/on airplane mode or restarting the phone doesn't help. I have normal data like 5 min and then it just freeze all signal reception . I live in the city with great signal coverage. What should I do?
But what's the coverage like where you live? Does it get better as you move around? If the coverage is good then contact Samsung support so they can maybe check the phone further
Coverige

Coverage is great here. I took out my sim card today and was only connected to wifi, connection is better.
With inserted sim both wifi and mobile data reception is awful.
I was thinking to switch to eSim..
I recommend that you contact Samsung support as your phone is under warranty for 1 year. They are very good at diagnosing problems.
Hi, you mean 5G coverage? I've read that 5G antenna failure is known to happen in this phone, so you should bring the phone to Samsung so they can replace it, specially if you are under warranty. I don't see why you see a relation between the SIM and the coverage, probably it has more to do with the status of the antenna.
The problem is with both data connection, mobile and wifi.. I tried everything coz I want to avoid sending my new phone to service..

Samsung has an 800 support number you can contact 1st and they will try and diagnose your issue before sending it in. I've found they are pretty good at diagnosing issues over the phone.

Well I notice that if I take out Sim card from my phone that wifi has weak but stable connection.. With inserted sim card both wifi and mobile data connection are super weak and unstable. So basically I have this expensive with no possibility to use for normal calls
It's quite the same problem for me actually on my S908B which is on the latest September update (AVI3)
I live in a quite big city in France and my signal is quite bad, like 1 or 2 signal bars on 4G+ (i desactivate 5G as it drain too much the battery in my opinion).
Sometimes i feel like Wifi signal struggle as well at home... i don't know where this is coming from, but it's annoying me. I didn"t pay attention on when it's started to get bad signal, but it's been a while now i think
