data turning off, intermittent wifi issues - Sprint Samsung Galaxy Note 8 Questions & Answers

My note 8 is having weird issues. I'm on Sprint, with an unlimited plan. I'll suddenly get apps complaining I'm offline. I've got full LTE signal. Go into data, and data is off. Turn it back on and most of the time it's all good. Sometimes I need to reboot to get the data back. Also WiFi will disconnect. I can be within 10 feet of the router and suddenly it drops. When I go into WiFi, it shows connecting, then reconnects. I did a factory reset and only added a few basically apps, thinking I may have an app that is hosing things... No change. Anybody else having these issues?

Me too, it is very frustrating. It does it to me almost every-time i use it.

[Q] 3g data hangs

Hi guys,
on my xt1068 (5.0.2 stock, no root, locked bootloader), 3g data always hangs when I'm travelling (e.g. Home -> Work). The only solution is to cycle the connection....
When I'm at home it works like a charm, even for an entire weekend
The mobile data icon remains "on", with full bars and H/3g symbol...but I cannot send or receive data.
Any ideas? As you understand this is really annoying. :silly:
Thanks.

I have the same problem but not all the time and I'm still on 4.4.4, I leave the house therefore disconnecting from WiFi sometimes 3G doesn't 'pickup' esp. if I turn off WiFi after it has moved out of range, like you it displays 3G or H but no data can be sent, the only way to fix it is rebooting the device.
Do you turn off WiFi manually after leaving the house? as mine only seems to do it if I do that.

Hmm, I always leave the WiFi on. I'm going back home atm and I just switched it off. Let's see if 3g stays active...(even if it would be the exact opposite behaviour than yours)
Thanks for the tip, I'll keep you posted.

AT&T S6 Edge losing network connection - Why?

Just upgraded from my M7 to the S6 Edge last Sunday. Since then the S6 has randomly disconnected from both voice and text service twice. The display indicates strong signal and that it's connected but no incoming calls or texts go through. The first time required a reboot to regain connectivity and the second time it took over 5 minutes before it returned. Attempts to make outgoing calls timed out with no connection. Do Not Disturb mode is off and the phone is provisioned correctly. There's no warning that this is happening until someone contacts me using an other method. Any ideas?
I would try a factory data reset. Whenever I've had problems that almost always fixed them. Make sure you back up everything since it totally erases the SD card. If that doesn't work, get a replacement.
I have a complaint out with ATT right now regarding my text messages. Weirdest thing ever - I'm NOT getting text messages at random times from random contacts on my phone but I AM getting them on MightyText, how odd is that? I can't imagine why this is happening, and they've asked me every question in the book all the way down to if my phone had any damage, water or otherwise.... I just got this thing, no it isn't broken!
Hopefully an update or something with figure it out
Try disabling VoLTE option
Has this been happening on your WiFi or mobile data or both? If on WiFi Check with your router it can potentially be dropping packets. Please specify
I have a Microcell and I've unplugged it to see if that was the problem. It was still connecting fine on wi-fi when it did this. I ran a packet loss test and after five minutes there was 0% loss.
Aside from the packet loss did you manage to measure the jitter on the line? Also when connected to the microcell are you surfing through the WiFi or is it using your mobile data still?
It's not jitter either. A 5 minute run all showed times of <1ms . When this occurred the phone had been idled for a few hours and just didn't seem to wake up. It seems to be confined only to voice and text service.
Sounds like your network is fine. Just have to see what att has to say about the smscreen and voice. By the way have you try turning off the volte (enhanced 4g lte) feature as well ?
Well....it just did it again. Definitely not a conflict with the microcell. It seems that once the phone is on and displaying for 3 minutes or so then it will start to work. I've disabled enhanced LTE to see if that makes a difference. It's done this about 48 hours apart now three times. I'm about to dump this thing back on AT&T. I'm beginning to wish I had gone with an M9.
Phone was replaced under warranty. The new one doesn't have this issue at all. Chalk it up to a bad sample.

Stock, suddenly no wifi.

(5.1.1) I was on wifi at home. I headed out and have been on mobile data for most of the day. I went for a coffee and my wifi won't work. Tried turning the phone off and airplane mode.
When I click Wifi it says it's on with no networks available. I click More settings and it says Turning Wifi on, but doesn't.
I'd rather not reset the phone, any ideas? Thanks.
yea, reboot your phone.

I had that symptom once, while waiting in a doctor's office. Shutting down and booting back up solved it, but this was a few OTA builds ago (i.e., I'm currently stock, lazy me).
Perhaps delete/forget your current WiFi connections and retry?

My connections don't even show up. I'm gonna let the battery run flat and then try... if not, then reset phone.
I let my battery die, my phone turned itself off after about 4% remaining. 10 hours later and when you hit the power button , it shows the low battery warning, but won't turn on.
So, the battery wasn't completely dead. I needed my phone, I plug it in to charge... And WiFi!!!!!!
Just updated to lmy48m... no wifi again. YAY!!! <_<
I'm having this exact problem w/ my WiFi, and I'm now suddenly getting the "!" appearing ever since updating to LMY48M.
i've been having this problem with build LYZ28J & LYZ28K randomly wifi would stop working. i'd reboot my phone and it would work again then it stoped, so i called Tmo got a replacement this time it took a few days and happened again this time i called Google and they called Motorola they had me wipe cache while i was on build LYZ28J and it worked... then i got the LYZ28K update then 3 days later this morning wifi stoped working again. So i figured doing a cache wipe would work again, but it didn't so i backed up everything and booted into recovery and wiped the phone thinking it would work but that did... still shows Wi-Fi toggle off and says turning on Wi-Fi. Called Tmo again they told me to take it to astore anfd get it diagnosed but im going to call google and see whats up. anyone have any luck getting this fixed ?
I'm also having this problem. Stock 5.1.1
Well I get my replacement phone today let's see if this issue happens I'm going to set it up as a new device.
I had the same problem. I've had pretty terrific success disabling Google Connectivity Service, which I think is somehow related to Project Fi. I went into apps, force stop, disable. Since then, I haven't had to reboot my phone. Before that, I was rebooting, toggling airplane mode, etc.
It's not 100% better though. I have had to toggle airplane a few times. But it's been much less frequent than before.
Suddenly happened today, probably the second time ever. No WiFi saved networks, couldn't locate signals, etc.
Rebooted the phone, everything fine again.
Odd.

I can not connect at all to my work's wifi where I have to enter my AD username and password, just can't connect. It worked mostly fine before Andorid 6.0
It is flaky on regular WPA2 wifi too at home, sometimes have to toggle the wifi or even reboot.
Wifi on the Nexus with Android 6.0 is poor to junk basically.

Mobile Data connectivity Issues & Spen Button loose?

I know people have had Wi-Fi connectivity issues...but has anybody else had Mobile Data connectivity issues? It's a new phone and a new sim card but I'm still having issues? I had to reset my device in order for me to browse the internet or for me to send texts...TWICE within an hour. Any suggestions for this?
Also, is anybody's SPen button loose? I don't know how secure it's suppose to be, but if I run my finger back and forth as if I'm rubbing it, the button rocks back and forth as if it's loose. Not sure if it's supposed to be as secure as the home button on the phone or what

Wi-Fi and Network issues are being experienced by just about everyone. Because it's so widespread, this leads me to believe it is a software issue and we just need new radios.
Your SPen is like mine. Fairly certain it was made this way and is not supposed to be like the Home button.
Cheers
hum funny i havent had any wifi or 4g problems. I remember they said the s7 edge had wifi problems where it would randomly disconnect and not reconnect.
Which i didnt have that problem on the s7 edge either. (got the phone 2weeks after launch).
But with the note 7 no problems here. And my spend is pretty stiff no loose feeling on the button, feels almost like the home button
I've had really bad issues too. Like having to restart my phone to get data to work. receiving text messages late. Phone calls going straight to voicemail.

Same here. I simply notice that after an hour I dont seem to receive any kind of notification, suspicious. So I check my phone and keep getting pop up of "no connectivity please check your network". Both Data and Wifi will not connect. Even toggling airplane mode won't establish a connection. Only option is to reboot. This has been happening to me at least twice a day.

I have been having those problems too except it's with my data and regular service. If my phone loses service somewhere the only way to get it back is to restart the phone it's ridiculous and the signal is way worse then my wife's S7 Edge

id say report it to samsung via online chat and they will make a case about it and hopefully they will make a patch.
but as said i dont get that problem. Background data and everything works. my package tracking, ebay, facebook and all that work. No miss called or messages.
Definitely have an issue when I roam on AT&T then come back to a T-Mobile area. Have to put it on airplane mode and then back for it to acquire the network again.
I haven't had any WiFi issues, but I rarely use WiFi. I have noticed that my Note 7 like to switch to AT&T Edge (which is basically unusable for data), even when there is T Mobile LTE available. I constantly have to manually search for a select T Mobile for it to switch back. I don't want to disable roaming, because it's necessary where I live, but I can't seem to keep the phone from switching over to AT&T or get it to switch back to T Mobile when service is available. I just switched from a Nexus 6P which very rarely had this problem in the same area.
I too have experience Data loss where I have to toggle airplane mode or reboot. But this only happens at my residence which has a poor to fair T-Mobile signal.

Same here, only once, but I noticed the one time it happened I had been using Bluetooth, more specifically Samsung Gear connected to my Gear S.

Well this is my first cycle but no issues yet. Spen button does the same thing. I think thats normal.

I had no issues, maybe don't use phone often enough to notice, but I have been in and out of network and it works fine without any reset. but here is the funny part: when i went to activate my N7 (from home computer), I had to call rep, of course from my old phone. So while he is trying to switch me, he sms me some code to input (still on old phone), didn't get it, sends again, nothing still, then my old phone connection goes dead. So i grab my new phone, sure enough, I'm switched, new phone now works. That was around 9pm. 3AM my phone beeps, I got 2 SMS messages with codes from 6 hrs ago. Since they were originally send to my old phone, which worked fine like forever, I would speculate the issue was on TMO side, not my phone. So I wonder if some of the issues some of you experienced are coming from T-mo? I don't know, like somebody forgot to program new phone into system and things hang up,
I switched the mobile network selection to manual instead of automatic and turned off data roaming and haven't had this problem since.
I have had no issues like this? Why are some many users having issues with this phone. The Note 7 is built pretty dam well. All my friends i know have this phone and no issues with them as well. Before jumping the gun on issues please do research.

I'll try this and keep an eye out. Next step for troubleshooting will be to get the SIM activated that came with the N7 instead of using the one from the S7. I've read that using a SIM from a previous phone has information stored on it and could be the cause for some problems. That just doesn't make much sense to me since they both have the exact same T-Mobile bands but I guess you never know. Thanks for the tip!
I have noticed on my N7 if I lose service (building elevator, etc) and then come out into open air, one out of 5 times it never reconnects. I try to cycle through Airplane Mode and out, but that does nothing. The only way to get data back is by restarting the phone. Super annoying, especially when I have a password on the phone and a sim lock so by the time phone is back up and running to use, it takes some time. Very frustrated with this!

I just experienced this. Ironically I had full LTE Data bars but 0 connectivity running T-Mobile stock Firmware and NOT rooted.
At least 3 times in the morning my data has been off, showing full bars but no LTE, a reboot was the only thing that got it up and running again.
As for the S-pen I'd say it's semi loose when fondled..

Question Wifi <-> Mobile switching?

I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
