LTE problem after factory reset - Samsung Galaxy S10+ Questions & Answers

Hi everyone,
I have a problem with my S10+. One day, my cellphone didn't work suddenly, at that time I was in the basement of a building.
I have a habit of using my cellphone as a road guide through the map, pasting it on the dashboard of my car, where the tool to attach it is right on the car's AC cavity.Maybe because it's too cold, it suddenly doesn't work, and indeed my cell phone feels very cold and immediately OFF.
I tried to revive, but immediately OFF again, even though it has finished booting. Until I have to go into Recovery Mode and I turn it back on. After a few times such conditions, finally my cell phone can turn on, but the LTE signal does not appear, and sometimes appears but the connection is still very slow.
I try to bring it to the Samsung service center, but only do a Factory Reset. But that problem still occurs until now, and finally I just use Wifi only for its connectivity, But if 2G can still be done.
Do you think anyone can help me with this problem? So that my 4G can be back to normal? I've tried using another SIM card to this phone, it's still like that.

Hopely anyone can help me up

Same thing happened to me today... when I camed out of work my phone's 3g/edge icon was gone. I decided to reboot and the phone was working but with no data. I then reset to factory setting and now I cant log in because there is no data. I tryied my other phone and data is fine. Something happened to my g1 that the 3g and edge is not getting turn on... i am on hold for a t mobile representative
ha u must live near me in florida then lol i talked to the people from t-mobile from there store and they said the 3g towers got a bug and shut down
Early this morning my coverage went out.... no 3g or data... I tried to manually start data and that didn't work... I went to bed and it came back when I woke up.
Maybe this is temporary.
i was experiencing the same problem all afternoon data has JUST returned however. Patience fellas. No network is perfect.
Wow, I am glad to see others experienced this. It happened to me right around 4:50 Central time. (I know because I was walking out the door at work.) I was logging into IM and I had a signal then it went away, completely. I had no 2g or 3g at all. When I got home, WiFi worked fine, but nothing else. Hours later I tried it again and no go. I turned on airplane mode, then turned airplane mode off and then 3g and 2g came back on.
The only thing I did out of the ordinary was mess around with bluetooth, I hadn't used it up until then. I will play around with bluetooth some more to see if it is somehow related, but after reading others comments, I doubt it.
By the way, I am in the Chicago suburbs.
My data was down until about 12:30 AM last night. I'm not even in a 3g area either.

Phone sometimes disconnects when using WIFI

hi, sometimes when i look at my phone, usually after being on wifi the phone shows no bars.
sometimes it comes back on in a min, i tried airplane mode but it wouldnt work. so i restarted it and worked fine.
not sure why it happens, does anyone else have this? could it be due to some Wifi calling setting? not sure why phone seems to just cut off.
anyone have any idea why this may be happening?
does it turn off radio for wifi calling somehow or? just random.
I have a similar issue, but not equal. Sometimes, when I try to connect to the network I always do (home), it simply doesn't work. Scanning - disconnected - scanning - disconnect. Only a phone reset fixes this.
Sheep ROM 2.0
AbyssNote Kernel 2.5
I had a similar issue a while ago and sent Mine back to the seller but the seller claimed neither they nor Samsung could find a problem with the phone. Thankfully The seller sent me a replacement which no longer gives me this problem so it may be the handset, though it could also be the setting/Conflicting app. Someone reported here his problem Was solved after adjusting a w ifi regulating app
i have a 3-day old gnote and i started noticing this problem after i have my phone rooted. the wifi icon stays on but there's no internet connection. turning the screen off and waking the phone after a minute solves the problem but its annoying to be losing connection when you're needing it. i'm on stock KKA.

Not a user error so need to contact Samsung-don't think is anyway
I have a somewhat similar problem. When I am using wifi for somewhat long time, I am unable to connect back to my 3g. Or if I was on 3g connection and I move out of coverage area for a little more than 10 minutes, I can't reconnect to 3g. Only 3g connection has this problem though, everything else works fine.
If I restart the phone, I can reconnect. Setting to airplane mode and resetting doesn't help. Neither does resetting the mobile network operators.
Yes, the problem seems to be software related since there is no actual problem with receiving 3g/phone.
yesterday i drove back 10 hrs and streamed music/radio the entire way with only a few tiny interruptions in reception.
but often still if i just take my phone out of my pocket, the "phone" part will be off and usually turn back on within 1-2 mins.
but this is quite annoying since sometimes il literally be waiting for 1-2 mins to place a call.
my phone is "not" rooted.

Sulking data connection

Hi,
Still in my first week with my Note (UK rooted stock GB) and loving it.
One minor quirk though - where I currently am (hospital :-( ) I have no wifi and only an iffy EDGE signal. Sometimes the data connection struggles, drops and re-establishes itself, but occasionally it just stops trying and the only fix seems to be to restart the phone - toggling data/airplane mode on the power button, turning off/on data via the settings menu and firing up another, comms-based app doesn't help.
Can anyone suggest anything more convenient than a reboot.
Thanks

Fresh Network Booster and Network Booster
both working great, try them.
Yep, those are the ones I installed. They seem to improve signal bars but data transmission has still been crap until a short while ago - maybe there's a local cell problem - I'll keep persevering, but hopefully I'll be home in a day or so.
Lost data again today, tried the apps - no luck and after about 30 secs the signal bars were replaced with the 'no signal' icon.
I switched on airplane mode, waited a few seconds and tried to turn it off again but pressing the airplane mode button did nothing.
In the end I switched off/on, the phone came up in airplane mode but let me turn it off and everything was OK again.
Does this just happen in one location? Like maybe it's just weak cell sites? Just curious.
Could be - I'm still stuck in hospital so can't try elsewhere.

Alright, well, let us know if you have problems when you can try it somewhere else.
Also, strange that the hospital doesn't have wifi. Every hospital I have been to does. Lol.
Same problem here, looking in the whole forum it seems that some One X users are having the same issue... really annoying, hope its not a hardware issue... theres a really low stock of Galaxy Notes here in argentina...

[Q] No Signal, Factory Reset

Guys
any of you had any bother with your mobile signal?
I'm on Vodafone and from this morning my signal bars are empty and I have no mobile signal.
I tried selecting Vodafone and Automatically select from the mobile signal menu, never made any difference.
I did a factory reset of the phone and it worked great, logged into google, restored my apps etc and it was all good
Then 5 minutes ago the same happened again, no signal and nothing I do makes it come back on bar another factory reset???
I've tested my sim in another phone and it is fine, no drop outs, no issues, I hope it's not a faulty phone (
Any one else had similar or can think what would be causing this?
Thanks
UPDATE -
Happened again, no signal bars, no connection
so this time rather than a full factory reset I removed the apps I had reinstalled, which were Spotify, Facebook, Twitter, Tapatalk and Whatsapp, rebooted the phone and my signal is back to full strength again???
Could one of the above apps be the problem?, is that even possible?
Its got to be some software problem.. These apps cannot cause such a problem
thats what I thought.
I've left the apps off for now, and if the signal seems ok after a couple of hours I will start putting the apps back on one by one and see if anything obvious happens.
The only App I thought maybe could cause it would be whatsapp as it ties in with your mobile number.....I'll see what happens throughout the day
happened to me once, all I did was put it into airplane mode and then back out of it again, and all was well
Same thingg happened to me. I'm on tmo though. Its defective. Waiting for replacement
I take it you've all changed your SIM cards to be on the safe side?
My experience is that the signal does have a tendency to drop out in weak reception areas and is slow to pick it back up again. I'm on vodafone in the UK.
I'm on orange and today I had nothing but problems. Dropping signal and everything I am not sure if orange is having problems. Had a HTC one s before never lost the little H above the signal bars.
Should I look at getting a replacement sorted.

I'm having the same problem with T-mobile in the US. It seems to mostly be an issue for me in areas of weak coverage. A reboot or any other way of resetting the phone connection fixes it, but still...
Been happening all day. Even now I have no mobile signal and yet I am on here using mobile data.
Usually a full reset would bring the signal back for a while then it would go again. On one occasion putting it into aeroplane mode then back again worked, but only the once. It looks like I'm taking it back this weekend unfortunately.
i had this issue when i first got the handset on o2, but after a while and me putting the o2 sim in, it picked up signal, swapped out for my orange sim and hey presto started working fine. It's been like that for a week now, but last night the battery died when i was asleep and after a charge this morning, no signal again on my orange sim. I'm in work now so cant swap out for my o2 sim as its at home, but will try and borrow somebody elses sim to test when they get in the office later this morning, Very annoying!
same issue discussed here: CLICK
Just tried another sim, o2 this time. Same issue, so back to shop on Saturday. Question is do I get another one or plump for the sIII or an htc

Mobile Data will not enable!! (Dynamic Kat)

I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.
Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.
Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?
Bad signal / carrier issue?
Call them and report a fault in your area?
I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.
Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth
Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
