S10+ loses LTE and drops signal constantly - Samsung Galaxy S10+ Questions & Answers

I've been having my S10+ on Verizon which I got in March, constantly drop from 4G to 3G, to noG. I didn't have this problem with my S8+. It appears many other people that having the same problem with not only the S10+ but other S10s on other carriers as well. Supposedly Samsung is supposed to release a software fix, but Sprint is also having people return their S10+s and get replacements because supposedly many of the first ones made have a hardware issue causing this. Anyone on Verizon or other carriers having similar issues and any update on the fix software or return and get new phone or otherwise?

Sounds like the same problem I had on TELUS in Canada. Took it to Samsung and they told me they had to replace motherboard. Fought with them like cats and dogs and they refused to give me a new phone. After waiting over a month for them to fix it, I immediately sold it and bought a Huawei P30 Pro. Will never have another Samsung Phone after that fiasco...

Not sure. Supposedly the first few batches but I'm not sure of date ranges. All I know is this has been the worst reception of any phone I've had and it happens alll over. Drop LTE and if i hit Airplane mode on and then turn it off it comes back. In fact I just had to do that right now to reply.

I had drop LTE signal issue, sometimes lte won't come back until reboot the phone but after do a reset network settings my phone works significantly better:good:

Am having the same or similar issues my internet is working all fine and out of nowhere i loose internet while still having full signal bar. I tried airplane mode and nothing seems to bring back the internet only thing that works for me is a reset am on AT&T

This seems to effect all s10 models regardless of the carrier.
I have a Verizon s10 plus that I pre ordered.
My LTE will have poor speed and randomly not work even though the status bar shows a signal in spots with good Verizon coverage. I also noticed that my bluetooth will randomly disconnect from devices and is very glitchy. Also the battery life has been not great. Only about 5 hours SOT with lot of apps disabled and all settings adjusted for maximum battery life.
Also I noticed that if you go into settings/connections/mobile networks and observe the signal strength it is always either -120dbm 99asu or "not available" which is not good.
I Noticed the LTE issues after an update(not sure which one it was)
I tried Updating to the latest ASD9 and there is no improvement.
I did all the basic troubleshooting through verizon(new sim, provisioned the device again). No improvement
I reset the phone with no improvement, I flashed the factory firmware ASD7 with odin.... no improvement.
Finally I brought the phone to a local Samsung experience store.
They tried to run some tests but it would not complete them. They were well aware of the problems with sprint phones but were surprised to see these issues on a Verizon phone. Eventually they agreed to replace the motherboard but had an issue flashing the serial number to the new firmware so now finally im going to get a new phone. Fingers crossed, this has been such a headach

Stuck in 1x mode?

Hello everyone.
I just got my phone back from Samsung after it wouldn't power on, then had trouble getting it to stay connected long enough to activate. So, I brought it in to town, hooked in to wifi, and had no issues. Got the phone activated, waited for a while, updated the PRL and Profile, and waited around to see if it would start working for me. Unfortunately, it was still not working very well. Put on the 1x/3g mod to see if it was actually getting 3g. Found that it was not... Finally, I contacted sprint to see if they could help on tech support. He said he would contact the network people...
I was like, hmm... at different location now, checked at the sprint store, updated one of their phones PRLs, and it seemed to start running slowly too... so I downgraded my PRL to see if that would help, it did not. Finally, I put on the 00001 PRL really quickly to see if I could get 3g... seems it didn't leave sprint or the 1x.
So, put it back to the original... was wondering if anyone has some advice?
Thanks much.
UPDATE: So, the radio has been flickering on and off for data reception, went up to Green Bay today and it went into 4g, then 3g, then nothing for a while, then back again...
Right now it is on 4g again.
Is there any way to check if the radios may have something not working? I would say maybe it is just network upgrades, (really, really hoping this is the case), but then I would think that Sprint would have said something when I contacted them about there being upgrades....
Thanks.
Take it to a store and ask them to test the radios. They could be faulty.
Mines been acting the exact same way...altho mine has not had problems before needing to be sent to Samsung.
2 weeks ago it just started not going into 4g as much as it used to...and RANDOMLY totally dropping any data connection 10x a day. Literally no 3g/4g for 2+ minutes at a time..no amount of airplaine mode/restarts fixes it......its like im back to the SgS2 days.. ****im sick of Sprint/samsung

It's sprints fault, not samsung. I have the same data drop problems, especially around NYC/NJ. I've had the same issue on my previous S3. My GF has no such issues on her S4 or her previous S3, but she has AT&T. Chances are Sprint is doing something with the network in your area currently.
Try this
1 - update profile
2 - update prl
3 - open the dialer and enter ##72786#
Your phone will reboot and go thru the activation process
If that does not help, call sprint and find out if there are any network vision enhancements in progress for your area. Unfortunately when Sprint does their updates it gets REALLY BAD until they are done

AT&T LTE Speed

After activating my 6p on AT&T I noticed slow LTE speeds compared to my Nexus 5 (not just speed tests, actual browsing/usage). Contacted AT&T support to verify IMEI and SIM information and they did some sort of SIM refresh on their end. After that I was getting around 70-80mbps speed tests for a few days but now the speeds have dropped back down to 5-10mbs (if that).
I've tried switching to PHONE and PTA APN's and no difference is observed. I am not on an unlimited plan so no throttling should be taking place.
My friend who is also using a 6p on AT&T is seeing the exact same behavior and had the exact same results after contacting support (fast speeds after refresh but slows down after a few days).
Has anyone else been experiencing this issue with AT&T or any other carriers? I'm not sure if this is a radio firmware problem worth reporting to Google or something on AT&T's side.
I'm having this same problem, my s4 was at least double the LTE speed of my 6P, I've been searching for a fix but this thread is the only one I've found so far, I did see VZW post where you can dial a certain number and select bands, I'm hoping someone can share a fix life that for us on AT&T
same here ... very slow compared to all the other phones I have that are AT&T branded and much slower compared to Nexus 5 and OPO. Also every time I call somebody, phone drops down to "H" and then connects the call. No calls over LTE.
I'm having the same issue and lately I keep loosing my lte and seeing only the H for 4g

I bet 6.0.1 is at fault. Did you recently update OTA?

yeah but i was having issues before the update
I wonder if it's something with AT&T network and this phone. I'll have full bars (LTE) and no service quiet often. I live in south florida, so we generally have great reception for every carrier.
The issue started for me as soon as I upgraded. I tried the older radio as well. I went back to Chroma 6.0 and all is well. I did star the issue in the tracker.
Well I just got off with att and they reset my connection to the network and so far so good. Lte all around. I will watch the next few days and let you all know

I have actually gotten the same problem, after updating my 6p to 6.0.1, I have lost my LTE and just stayed at H.
I haven't done nothing other than updating, I really hope this gets fixed soon, the speeds arent that bad but I am used to having LTE all around
Well I called att this am at around 8am and tight now at 6pm its been solid. They made me shut off my phone and basically set up my phone network wise as a new phone and boom LTE everywhere
Happening again. I reset network settings and boom all is well for two days
I found a recent post on reddit where a user was having issues with the phone connecting/losing LTE. After troubleshooting with AT&T support they indicated the "APN type" setting was missing an entry and in the improper order.
Changing to the proper order fixed his and others LTE issues and so far it appears that it has fixed my speed issues as well.
The fix applies to both nextgenphone and phone APN's.
Default APN Type on 6p = default,mms,supl,fota,hipri
Correct APN Type from AT&T support = default,admin,fota,mms,supl,hipri
Hopefully this helps.

No Service

So ive had the phone since launch and in the past 3-4 months i'd lose signal quite often during normal usage. But in the past month it happens pretty much every time I use it. Im on T-Mobile and I know they had some problem with the Nexus phones on their service back in August but I thought that would have been fixed by now. And then an hour ago I lost service and I cannot get it back at all no matter what I do. Im on stock 7.0 Nougat, non rooted. Ive tried all the resetting methods and what not but no go.
Any help would be appreciated, hopefully its not hardware related
I don't think it's hardware. I have the same issue on my device. Rebooting usually brings it back for me for a while
Sent from my Nexus 6P using Tapatalk
Same issue here... I RMA'd my device last week and same exact issue on this new device. I'm also on T-Mobile and I even got a new sim...
If you keep up with T-mobile news. They've been getting outages intermittently in certain locations.
It's gotten so annoying I can't even use the phone unless I'm on wifi. It cuts off service like every 10 seconds no matter how strong the signal is
I've attached a pic of the service menu.. Everytime the service goes out it always switched to the CDMA network even tho T-Mobile is LTE and what not
mines been doing this too, even wifi calling will go to no service sometimes.
I've only noticed it since I've been on benzo rom tho, not sure if its related.
OK so my theory was true, tested it many times.. looks like something in software or hardware of the 6p is making it switch from LTE to CDMA causing it to drop service and then I have to manually switch it back to LTE
I feel as though it's related to the cell towers. I spent the weekend in DC and I didn't have any issues whatsoever. I came home to Pittsburgh and within 30 minutes if being home I had my first loss of service
Sent from my Nexus 6P using Tapatalk
I'm in Atlanta where they should have good service but it's everywhere around here it happens
I just opened a ticket with T-Mobile so I'll follow up with whatever feedback they provide me withing the next 72 hours!

Inconsistent 3G & LTE performance, defective unit?

Don't get me wrong, I love this phone despite the bugs. Software bugs.
However I've a serious issue regarding the 3G/LTE module. 3G/LTE performances are not consistent at all.
Sometimes it goes well (chatting, sending pictures, even testing the speed with a speed test) but other times the connection "hangs" and I'm not able to do anything for seconds or minutes (download pictures from whatsapp, sending text with telegram or open web pages). After that time, the connection seems to work again. When this Is happening, phone is at full signal.
Please note that I never had these issues with all my previous phones (Nexux 5, Nexus 5X, OnePlus 3T) with the same SIM card and under the same conditions (places, time of the day). I've performed all the updates available (software version 4.5.4) and cleaned the cache many times using the recovery.
I'm asking your help: is there some debug feature I can activate in order to see what is happening and understand the problem? Many thanks.
What carrier do you have?
ATT had to load my phone into there system. I'm in Seattle, WA USA
After they did that LTE has been perfect!

Since I'm on ATT and I might get a OP5 I gotta ask how you went about this. Because I can see me telling customer service this and them not having the slightest clue what I'm talking about.

Basically you'd call in and ask to register your phone. It's not actually necessary but they do this anyway when you ask for a replacement sim. All they do is get your IMEI off your phone and add it to your account. Though with the 3 it already showed up during use. I don't think it matters much at all. Haven't had an issue with the 5 in Wisconsin, Minnesota or Nevada. I've simply plugged in the sim to this phone and went on my way since day 1.

Just to give you the big picture, I'll include everything that happened when I got my OP5 in terms of registering the phone on AT&T's network...
I got the OP5 and I came from a OPO, so I needed a new nano SIM card. I went to AT&T and they gave me a new sim but they were not able to get LTE signal at all. I was impatient and really didn't want to wait around so the rep and myself came up with excuses on why it wasn't working so I could get out of there. HSPA+ was the best I could get and it was about ~5Mbps up/down and I was happy with that for now.
I got home and decided to call in. Usual phone tree hell with AT&T began but I eventually got a level 2 Android technician. I will note the default values within the phone tree took me to iPhone support. Anyhow, the level two technician verified that my phone was not getting LTE. Furthermore, the device was not registered in the system at all. He gave me two options (which from the sounds of things, he wasn't supposed to do) 1.) I could just deal with the HSPA+ connection and it could take up to 5 days to fully load the phone but my phone would work perfect in terms of service/coverage/data rates (HSPA+) or 2.) He could load a Samsung S7 mock profile to my phone and it would more than likely work fine but don't hold him accountable for it. He said if it were him, he'd go for the S7 mock profile so I went with it.
Immediately I got an LTE signal and he had me reboot my phone. I've zero issues as he figured would happen and everything has been perfect. I got a confirmation text message from AT&T saying my phone will be loaded by July 6th and originally the technician told me around July 14th.
Anyhow, that was just my experience and a good experience at that. Of course, popping a sim out and back into a new phone would be ideal but a non-contracted AT&T device has to get loaded at some point and time I guess, right?
Cheers!

Did you try rebooting the phone before calling? That is what happened with my Moto X Pure and no one knew what to do at the store. The manager came out and rebooted it and it got LTE and worked fine after that.

You mean, did I remember to turn it off and back on again? Yes, we tried that. Haha
It wasn't until the AT&T tech adding the profile to the network that it works. It was instant too.

Horrible signal new S10+ on sprint

Anyone else on Sprint with the S10?
Note 8, and S8+ works fine. My S10+ is getting 1x and when I'm on the road, it would come in and out all day long. Without WiFi the phone is almost useless.

i have the exect same issue with s10e..i thought it was only s10e because its a cheaper model..what do we do..plus also my wifi is pritty bad..only on this device
My wifi works fine but I have very limited if any data signal and I can hardly send or receive text messages....
No one has a fix?
I called the sprint store and the guy said lots of these new S10 series phones have connectivity issues.
He said their tech has a fix for it but it may not be effective. He said Samsung needs to release an update to fix it.
I've got the S10+

I used to believe in this statement.. But when I walk around with a phone from Verizon (business), Srint (Personal) and AT&T hotspot service, I realized this is very not true.
There are locations where each carrier is stronger than others. At one of my job site, Verizon and AT&T fail to connect at all constant roaming and drop calls while Sprint skips along like no body cares.
Point, additionally, as each carrier acquire and deploy new bands, they need to be built out so the newer devices that support the bands can utlize it relieving the crowded older bands.
HOWEVER, this stupid phone, with SignalCheck Pro installed, I can see the bands I'm on but the signal stregnth is horrible, like at the moment, i'm connected to band 41 but LTE is at -117dBm, that's almost like not having signal at all. Likewise when I'm connected to band 25 and 26.
I tried disabling all those bands and force it onto the lower frequency with hardly any success.

Can you disable or remove that signal check program? Not all sognal check programs are legit.
What country are you in?
That may be part of the problem.
I agree, carriers do have their own pros and cons.

and yes the program can be uninstalled, but it was only installed because I need to troubleshoot this issue, so it's not the program that's causing the problem. It's just telling me what band I'm on and the signal.

It's not just you. There are multiple threads on Sprint's forums with users complaining. My phone constantly roams, the WiFi calling keeps timing out on location and though it says LTE most of the time data doesn't work. Lucky for me I keep a spare phone so I'll be switching back to my iPhone X until they resolve this but there's been no official word on any of this getting resolved so I'm not expecting a solution any time soon. I'm wondering if it was the update I installed that caused this because it seemed like day 1 the phone was ok. Maybe a solution is to use Odin and flash back to the original stock.

They had me reset network settings which I did and it didn't help. They're sending me a replacement phone... Once I get it I'll prevent the Samsung update and see if that helps. Idk I really wanted to like this phone.

Do you guys have a Sprint phone or the unlocked version from factory? I have the factory unlocked version, could it be it? The sprint guy @ the store said they sold a few s10's and no one has come back *****ing yet

I have the sprint version purchased from S
Spent an hour with samsung to no resolution. Took my verizon sim and dropped it on the S10 and the phone was getting good signal and speed then dropped for a couple minutes then back to good speeds. But as it's doing this, the phone started to get very warm. Sprint tech support doesn't know crap, just make me repeat their written process multiple times and the guys at the sprint stores are just salesman.
Since the verizon seems shows intermitten connections as well, i'm going to see if samsung can send me a replacement.
