For me calls are OK. Since yesterday I have Factory reset twice with same problem appearing again.
I am thinking to load custom ROM and see the result.

The question is, is it actually going to solve it?
And if not what moves it takes to get it fix?

I wonder if your provider is supporting bands used by that model. Turn off lte and check if data stays steady.

In this case LTE should not work at all. But it is disconnecting itself when I am using LTE and suddenly DATA is gone.

I suggest upgrading to android 6.0.1(N910TUVU2EPG2) using SAMSUNG SMART SWITCH in your computer or go to the setting>About Device>Software Update.

Download and Odin official firmware. You have a old modem that is mismatched from the operating system.

[Q] gs4 active i537 4g issues

I recently got a sim unlocked gs4active (i537). I rooted the device and used app quarantine to quarantine the files so that I can create a hotspot using my 4g signal. that process worked well. however since I got the fone I am unable to use any internet apps (eg google play fb twitter ) using my 4g signal. when using wifi these apps works as it should, however when using my 4g signal I always get the no connection error message. it should be noted that when using 4g signal I am able to use wats app and viber to chat but I cant send/ receive any sort of media (eg photos and music). can some lend some assistance on whats wrong here
Are you sure your apn's settings are ok? Are you talking about using a 4g lte network or a 3g network? I'm probably in the same situation as you since I have a sim unlocked sgh i537 and I'm using hspa with any issues.

Have you tried the obvious? Unquarantine those files and see if it works then - that way we'll know what end to start trouble-shooting in.
Good luck!

I was experiencing this problem before I quarantine the tethering provision file so I highly doubt quarantining this file was the cause of this problem
just to be sure I just tried un quarantining the file to see if it works ...... and it doesnt
try this :
go to settings- more networks- mobile networks- Access Point Names- then hit menu , then- reset to default.
and make sure your Mobile Data on phone is enabled.
wow!!! this works!!
thanks a lot ... now I have a perfectly working s4 active

[Q] Sprint G Flex loses service

Has anyone else experience complete signal lost in about every 15-20 min? Ive attempted a factory reset also a ##UPDATE# .
Goto settings->more...->mobile networks
Change it from Global to LTE/CDMA (if in Sprint variant) and reboot
I had the same issue as it will disconnect to search for a global GSM network to connect to every few mins and then reconnect to back to its home network when in global mode.

I live in LA and I get fast Spark speeds @ 30.00 Mbps on average. But what I notice is when I drive in my car or go to neighboring cities it constantly drops from LTE to 3G and the internet would be intermittent until I become stationary and would go back to LTE.
I will try lostsoul77 advice and report back to you tonight.
But yes, every 10-15 minutes it switches between 3G and LTE,
I attempted to change the settings to no avail. I've come to the conclusion that it may be a defective device and will be swapping out for a new one.

Did you reboot after you changed the settings. Try changing the setting, then update profile and prl and reboot
Sent from my LG-LS995 using xda app-developers app
I actually tried that as well! By the way I did end up exchanging for another unit. And unfortunately im still having this issue! Ive attempted update profile, update prl, ##update# , factory resets, settings mobile networks to LTE/CDMA instead of Global, and even manual programming using the MSL code. Maybe its something with the Sprint variant G Flex? Ive contacted LG and they want me to send my unit in for diagnose and repair.
I've had the same issues, here's what I've discovered.. Alot of us don't have band 26 and 41 up yet. And it's sprint wide.. Looks like the next firmware update will have the problem solved.

VoLTE calls cannot connect? Help please.

If there's any info I would greatly appreciate it. While on LTE only mode I cannot receive or make calls
I have played with the settings and got it to work a few times flashed different roms, and reverted to stock but nothing I have tried works.
When I turn it to auto or lte/GSM I can receive calls but it auto answers?
And It struggles to get LTE back without me setting it back.
Any info would be great.
Debating on weather I should go back to the nexus.

When you say you reverted back to stock, do you mean you did an ODIN back to stock COD6? Have you tried this from different locations as in different cell towers.

First what firmware version are you on?
When you say LTE only mode, how are you getting LTE only mode?
So in Call you have "Use VoLTE when available" ticked off and then in More networks\Mobile networks\Network mode you have LTE/WCDMA/GSM ticked correct?

So if you ODIN to COD6 and don't put in that code and just use the settings I listed above does it work? Is that when you say it Auto Answers?
It has always worked perfectly for me using those settings and not trying to force it with any codes.
Just to make sure you know, it is working if you make a phone call and you continue to see the 4G LTE icon in the status bar. Not being able to make or receive calls may be related to you trying the code instead of letting it work like it does out of the box.

[Q] Moto X XT1053 After Lollipop Update Problems

I update to 222.21.15.Ghost_ro-Retail.en.US I couple week ago and I have notice that You Tube sometime will stop the playback and just get stuck, also when I unlock my phone or lock it some time I get a crackle sound coming from the rear speaker, almost like it a re-verb sound from the lock sound.
I have cleared the cache partition and I have rest my phone from the back up and restore option. And that has not change these two thing from happening. The rest of the phone seams to be working find I don't know what else to do to fix this problem.
Same problem here with YouTube playback... 222.27.1.ghost_row.02.en.DE
Sent from my XT1052 using Tapatalk
Try going to Settings > About Phone and enabling Developer Options by tapping on Build Number several times. Then press the back button and tap on Developer Options and scroll almost all the way to the bottom until you get to the Media section. Try enabling/disabling Use AwesomePlayer (Depreciated) and see if that helps.
Thanks that tip seems to have fix the YouTube playback problem. Any ideas on the crackling sound made at random moments.

I just started having it. Totally random when starting a YouTube video, now it happens when I touch system items like home, back, the app drawer. Keyboard seems fine though.

Definitely software. It's totally sporadic. It stopped last night as I went to bed and then picked up this afternoon when I was texting someone.
Would re-flash using the
MOTO X, GSM Dev Edition:L-5.1-LPA23.12-15 (Retail) LMR1 fixe these software glitches. And if I am on lock bootloader do I need to unlock before flash this per Motorola instructions.

Anyone else having problem with cell data connection? Wifi works fine but cell does not connect. I have this problem using PTel (T-Mobile MVNO w/ LTE) and H2O (AT&T MVNO w/LTE). Truphone which is both T-Mobile and AT&T MVNO but has not LTE can connect but drops the signal quite often even in areas whith strong signal (-75 dbm or better).
I have checked the APN settings for all, cleared cache, done a factory reset and the problem persists. Before the 5.1 update I had absolutely no problem using all three providers listed above. Any suggestion is welcome since I am running out of idea and the next step is calling Motorola.

My data connection has been really good post-update, so I can't offer any assistance other than what you've already done. I would definitely confirm from your carriers which APNs you're supposed to be using and/or call them/Motorola about it.
Try different apns. Sometimes I need to try a few different ones listed before the phone works. Make sure you save the APN
i also had The crackling sound on my moto xt1053 but it was a gravitybox (xposed module) setting I had enabled. after I disabled that and rebooted the problem vanished. This may help others

I've had mobile data connections problems saying something like "failed sign in attempt with AT&T network" and the crackling speaker.
I called AT&T, who did something on their end. It did work, but when I switch from WiFi to mobile there is a moment or two when the !sign-in failed symbol pops up. But, the signal returns soon.

Unlocked US Note 9 loosing mobile network

Hey All,
I just got an unlocked US version could silver note 9. I am on N960U1UEU1AEL1 firmware and T-Mobile network. I seem to have an issue where the phone is dropping connection. It shows the LTE icon in the task bar but I cant connect to the internet. I have to restart the phone in order for it to connect. It seem to be tied to a wifi or something along those lines. If I connect to a wifi then walk away from it, the phone has trouble picking a tower but it shows that I am connected to LTE. I tried adding new APN settings but it defaults to the T-Mobile APN. Do I really need to flash TMB firmware, I really liked the unlocked version without all the bloat. All help is appreciated.

That Baseband or Software version doesn't sound right. AEL1 isn't a version I see that was released.. All Unlocked software versions are AR**. Double check that.

Have you tried resetting the network settings? That's where I would start. Could be a bug with your software. If that doesn't work try rebooting the phone into recovery mode and wiping the cache partition the reboot. If that doesn't work back up your data then factory wipe the phone.

I haven't tried resetting the phone yet. This is my first phone that is not rooted and I started using Blokada from day one. I wonder if Blokada is causing this, hmmmm.
Ok, I did some more research and it sppears to be an issue with Blokada version 3.6.
