What happened to my cellular data? - Samsung Galaxy S8+ Questions & Answers

Twice today I was happily surfing the Web using cellulat data, when suddenly, I lost the ability. Still showed 4G/LTE connection. Just stopped from one click to another.
Rebooting solves the problem, but I've never experienced this before.
Anyone else?
TMO 64 GB S8+.

Twice now. Annoying. ?

Mobile data suddenly stops working

I have experienced this twice already. Tried turning off data, radio and turning back on don't work. Must restart device to get back data. I am using notification toggle and using its 4g menu, I tried to test ping but the error is IP address unreachable.
Just a headsup for anyone who experienced this as I doubt there is a fix because I can't really pinpoint what went wrong.

Did you have wifi on? What are you on 1.73?
I had a similar issue where if I had wifi on with the stock firmware I would at random lose data connection turning off wifi then turning it back on seemed to fix it. I have since rooted and updated to 1.82 and so far haven't had the issue.
Just happened to me again about 20 minutes ago. I went into settings/mobile network/access point names and the checked the circle by AT&T PTA. I have NO idea what this does, but it immediately reconnected me to the data network.

I had this last week, update to 1.85 and it should be fixed.
Edit: retracted. Still have the problem on 1.85.

Yeah I've had that happen to me a couple times. Very annoying. You have to reboot for it to start working. Hasn't happened yet ever since going on cleanrom though

I switched to a new sim and that fixed my data connection issues. The sim that shipped in my preorder seemed to have problems.
It's happened to me a handful of times aswell.
However you do not need to restart your device. Turning airplane mode on then off will reconnect you.
I've been having this issue since day 1 as well. toggling airplane mode does not fix anything either. happens on both 4g and LTE, however it seems much more frequent on LTE and the phone really heats up when it happens.

It's only happened to me on 1.85. Sometimes when it happens I can't make calls, sometimes just Internet. Every time I've had 3 bars to full on signal.

How long have you had the new sim?
I also got a new sim. That was Saturday. I haven't dropped calls or been unable to call but I have lost data. Shows 4 bars but no 4g in a 4g area. When I go to settings it said not connected to mobile network. (maybe not exact terminology) restarting fixed it.

I have had the SIM about a week to 10 days. I remember reading about people having this issue and thought maybe it was the SIM. Worked for me so far.
I was like u and had the same issue except I would have to reboot the phone to regain a data connection.

I've lost data connection once, I did a quick on/off of mobile data in settings and it started working fine again.

i tried that, also airplane mode. only thing worked for me was a reboot
I get this when I go in a low signal area, and in Vegas no matter the signal strength. Just random data drops.

This is the same for me. Mine went out yesterday morning and I left it alone to see if it would correct itself, then tried toggling data, then airplane mode. Nothing worked but a reboot.

I ll add to the list. Same issue, and only reboot solves it. I thought it was a sim issue as well, and will get mine replaced to see if it solves the issue, as it is happening more frequently. And seems to happen when I put the phone into airplane mode when using a sleep monitoring app, the signal will not come back unless the phone is rebooted.
Rogers one X on virgin, 1.73
Yup this happens to me a lot.
I don't like auto setup so my data is only on when I switch it on.
Several times data will drop off and not come back.
I tested this out at home where it's mostly WiFi for me....happened several times.
Reboot is the only thing that fixes it.
It's random and once I reboot it seems fine, but still annoying.
This is just data. I have not had WiFi issues much. I'm still 1.7 ....

Same when I had the issue, airplane mode didn't fix it. For me it only happened on LTE, can't remember ever happening on "4G".
Strange but I really haven't had this issue since upgrading to 1.85. Maybe it will come back.

Data Randomly dropping but signal fine

This is driving me nuts so if anyone has any ideas, I'm all ears
My Nexus 5 keeps dropping data. The Signal bar will still display full with H, but nothing will connect. If I'm running a ping it'll just stop and then eventually kick back in with 10000ms or something - Anything else i'm trying to do just plain won't connect. Could understand if I was losing signal but I don't seem to be.
Haven't had a chance to try the sim in my old phone yet to find out whether it's the network or the phone - was just wondering if anyone had experienced anything similar? :S

happening to me with sprint 3g on the unofficial cm 10.2. have to toggle airplane mode, not sure if its a CM thing or a sprint thing since i literally flashed CM the next day i got it lol
still happens
a few cm11 updates and almost a month later its still happening
I just started experiencing this same thing in the last week. Real frustrating part of it (beyond the obvious) is that there is no way to tell this is happening unless you are actively using the network at the moment the signal is lost. So if the phone is in your pocket and not being used, you'll really have no way of knowing whether you are missing important phone calls/text messages simply by looking at the display of the phone. Each time I only notice when I am trying to load a web page and it says I'm not connected to the internet (even though it shows that I have a strong LTE connection). Talked to both Google and T-Mobile about this and both basically pointed their fingers at the other. I'm pretty convinced that the problem is on Google's/LG's end though.
Getting my third RMA in the mail next week. Will likely take them up on their refund offer if this continues. Believe it or not, the intermittent loss of data isn't even the reason I set up the initial RMA (or the reason I sent back the first two RMA's I received).
I have this on both Three and GiffGaff in the UK. I also had this problem on my old Galaxy S2, so maybe it's an android problem?

Fix for frequent data connection dropouts.

Terrible network connectivity since official Lollipop update.

Since fishing the factory images last week I have been experiencing a virtually nonexistent mobile network connection with my N5 on T-Mobile, basically 90% without connection where I used to get perfect reception. I've tried flashing the old radio, re-flashing Lollipop radio, factory reset, etc. Nothing helps. Is it just me or is anyone else experiencing this?

Did you do a full wipe? Reflash factory image?
I've done everything short of completely rehashing the factory images. Just factory reset the device an hour ago.

I'm on PTEL (part of Tmobile network). My cell data went to zero after I upgraded. Haven't left the house yet to see if it kicks in elsewhere, but looks like it's just not receiving it (since I use to get at least 2 bars).
Well, turns out it was a loose connection related to a recent screen replacement. Problem is solved, Lollipop not the issue. Kill the thread, dad.

Eh i was just gonna say that i have same problem it looks like mostly t mobile or t mobile engaged users are affected!
Im from europe, and i cant get LTE any more im loosing siglan periodically, only 3g preferred works. Really anoying.. Flashed factory image stock,non rooted, unlocked bootloader only if someone find workaround or have advice..yes please

sm n915w8 dropping service issue

I recently upgraded into the note edge and I'm experiencing consistent service loss. Seems like anytime I use anything network related ( cell network ) after a very short period of time it drops signal and take 5 mins or so to reconnect.
It's running 4.4 android and there are no official updates available to me
I'm on the sasktel network. This is very frustrating as I really do love the device.
I don't believe it's a hardware issue I strongly believe it's software related.
I've googled and have found that the Sprint Edge was giving some people grief but I have seen few to no solutions (and the ones I've tried have done me no good)
Please help!
Ive got the sprint 915p and mine does the same thing. Very annoying. Inly way to stay connected 100% of the time is to stay on 3g which sux. It is a known issue from what i have seen. Some phones are said to work themselves out of it. Inwiped my sim card points down with alcohol and forced my phone to reprovision and do a hands free activation. Seems to have actually helped some.

I also experienced the same thing and I thought I am the only one. Mine is a Bell Note Edge and using it under Telus network. Since acquiring this one 2 weeks ago, it has been a constant pain. There are times when my network signal would drop from 5 bars to no service and lasts for about 2-5mins for every 10-15mins of each hour. I had replaced my old sim card and purchased a new one a few days after getting the Note Edge. There are times that restarting the phone would fix the issue for about a few mins then it would go back to no signal. There are times when my LTE would just hang for a good minute or so. No problems with wifi connection and data up/down is consistent.
I also believe that this is software related. I had the somewhat of a similar experience with my LG G2 but this was in regards to the Wifi d/c issue. I had to wait 2 months for a dev to look into the issue and when he did, i flashed the modded kernel and wifi was better after that. I also contacted Samsung Mobile and the customer rep mentioned that they are not aware of any issue, which meant he didnt know jack at all. Hopefully somebody figures this out. I had to revert to my Note II as my daily driver.
Ya i wish there was someone out there that knew what exactly the problem was and could fix it. Its annoying when someone on here says its a known issue and clearly there are people having problems and complaining about it then the service representative says they dont know anything about a known issue.

I had the same problem with sprint. Went there and found out that I had a bad phone. They ordered a replacement and swapped it out. No issues after that.

Ya im gunna do the same thing its just a matter of having time. They want to look at your phone and "replicate the problem" before they replace it. I have already sat there for an hour to tell me about certain towers being down. I guess it was working ok for them when they looked at it. Its not all the time for me. Its that every once and a while when i got time to kill and i dont have wifi that it decides to act up that pisses me off
Sent from my SM-N915P using XDA Free mobile app
I get that too. There are days and hours where my phone cell network signal works flawlessly. There are days when I could barely get a signal.
Ya its random with me too. After wiping all the pads on the sim with alcohol and doing a hands free activation ot seems to be doing a lot better though

On sprint, since i updated to LP, this hasnt been nearly as much of a problem. .. 1 dropped call in a week, in a busy theme park, in a tunnel....

CyanogenOS 12 on Oneplus One, often losing signal and data

Since I flashed the OTA for Oneplus One that gave my CyanogenOS12 I'm having problem with my signal and data connectivity.
When I lose the signal, it's like impossible for the phone to get the signal back, and I often have to reboot the phone to get back to a signal. Yesterday even that didn't work.
Something like that has happened to me before, with a reboot needed, but now it's much more often.
Are there someone else that having the same problem like I do?

No. I'm in Sweden.
Turns out a lot of people having this issue with the LTE. Turing LTE off and it will work better. It's just like when the phone drops the LTE signal the first time, it has huge problems getting back to a signal at all.
