Hi I have the Tab S 8.4 LTE variant. When I went home to my province, my carrier prompted me to install GPRS/3G settings of that area so I installed them. But when I came back home, I'm losing service often causing my battery to drain fast. And the most annoying part is the screen distorts if I pull down the notification panel or open an app when I have no service. Already tried factory wipe using stock recovery. I am rooted. Could this be fixed by buying another sim card or just updating my firmware? Thanks

Hey guys, I picked up a new Samsung Galaxy S II (T-Mobile) about a month ago from the retail store.
About a week ago I was using my phone as a hotspot for my xbox and then I got disconnected while playing. I wondered what was the problem and I saw the data icon was in the no connection state. Now I restarted the phone in case it was the simple loss of signal bug but it wasn't. My data wasn't coming back on. No matter what I did the connection wouldnt come back on. I called the tmobile tech support and they gave me rubbish things such as reboot phone, take out battery and wait 20 seconds, and all that jazz. I then noticed a pattern starting with my phone, the phone would connect to 4g then a second later disconnect. It would repeat this all day and not change to anything else. If anyone can help with this problem it would be greatly appreciated.

I had the same issue a few weeks ago. It was the SIM card. I only had the phone for 2 weeks and got a new sim card when I got the phone. It just went bad. Go to a corporate Tmo store and get a new card. They will give you one for free.
I have this same problem with my SGH-T989.
I'm running CM 10.1.3 (Android 4.2.2), and it's vendor unlocked (used to be a Rogers phone) now on the TELUS network.
Data will randomly disconnect, but I still have all signal bars in grey. A reboot will enable it again, or sometimes it just comes back on it's own. I've been to the cell booth in the mall and they've swapped out a SIM card for me, no change.
I also noted that when the data isn't working, my WIFI doesn't seem to either. Modem issue? How can I tell what modem I have and what would be best? I assume CM 10 comes with it's own modem for this phone and when I flash CM it writes the modem too?
thanks for any help.

Flashing a ROM usually does not touch the radio. Newer ROMs(4.2.2 and later) need either the UVMC6 or TLMC4 radio from here:

Hey guys,
So my phone recently (after I unlocked it, played around with T-Mobile apn settings, enabled network mode chooser, and switched the modes around [subsequently removing that]) started dropping my LTE signal, and diverting to 4G. The 4G is still slower than my brother's HTC One's 4G (both on ATT), and the LTE doesn't even work. I can turn on airplane mode, then turn off, and get LTE, but it is freakishly slow, like Edge. So I was going to unroot, flash stock, and go to ATT for help. But, after I flashed stock, I dialed 3845#*980# (hidden menu), and at the bottom under LG RCT -> Display Result, it still says that I'm rooted. Does this mean that my flashing didn't work? Or does that mean we just can't reset the root counter?
I went to stock using this guide btw: http://forum.xda-developers.com/showthread.php?t=2302660&highlight=download+fail. Any help is appreciated!
Thanks!

i have the same problem on it, how can i fix this issue??
Cause i would like to send the phone back to LG and let them do the health check...
Please help
Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.

Good morning all.
My S9 is completely stock (Android 10) and I don't want to install any custom ROM.
Is there a way to force LTE only (Three network/UK)?
I have tried #*#*4636*#*# but this doesn't work. I have used a couple of apps that have given me access to the settings and changed it to LTE only and this is confirmed in the mobile settings page but the phone keeps reverting back to 4g (not 4g+).
I definitely have 4g+ here because it does connect if I reboot my phone and the download speed is double my normal rate but I cannot get it to stick.
Is there a specific APN I could use?
May I ask you for advice?
Thank you.

You can try with Force LTE Only app on Play Store since Scamsung is kinda blocked the Radio edit part on ONEUI. But be aware that on some firm, Scamsung devices will not be able to make phone call or receive text msg when on force LTE only mode!
That's one of the apps I have used but the phone just reverts back to 4g (even though Network Mode now shows LTE only).
Looks like I have been misunderstanding my network terminologies.
What I am trying to do is force my phone to stay on the 4g+ signal, because I get much better downloads. It is definitely available here because I connect to it for a few minutes if I reboot my phone. My phone is completely static with good, no fluctuations, signal.
Can this be done?
I'm at my wit's end with this. I got this phone last year and it worked perfect until the stock Android 13 update. Then it wouldn't hold a signal to save its own life. I finally have wifi here so it's not as much of an issue, but when I leave my house I have to toggle airplane mode to get it to work again, or it's stuck on "emergency calling only" forever. I did recently put Lineage on it, thinking maybe that would help. The last couple updates it's a little better, it will sometimes get signal back on its own. However more often than not I have to toggle airplane mode or reboot to get service back. This happens all the time, a dozen or more times a day depending on how often I lose service. I did try to search the forums for an answer, but I kept getting errors back with the exception of one result with the same issue that said "tmobile only" under the fix.
I have:
Reset network settings
Reset APN
Manually selected a carrier and switched it back
Cleared cache through Android Settings
disabled/enabled mobile data
Toggled Mobile data always active
Any help would be greatly appreciated. Seriously considering going back to my LG G8 ThinQ and selling this thing, but I love the cameras on it. Side note: When I put the SIM in my old phone none of these problems exist.

Maybe contact Verizon support. They should be able to fix it or at least tell you what the problem is.

I tried that. I couldn't get anyone that was a technician on the phone and eventually after three days of not getting an answer they closed the ticket.

WOW, glad I am with TMO. Their support is the best I have ever worked with. To me they set the standard.
You said you reset the APN, but did you check to see if the APN is the same as on your other phone that doesn't have any issues with mobile service? Maybe check to see if they are the same, and if not put the APN in that works

That's a good idea, I'll do that tomorrow. Thaanks!
Assuming you're unlocked and rooted since running Lineage, so add this module in Magisk, and maybe also enable mobile data always active in developer settings for now as well.

Exact same issue, unlocked LE2125, TMobile simcard. Didn't have issue on custom ROM, but this is happening on OOS13. Tried everything NSA SA 5g dev settings nothing worked. Living with trying to remember to toggle airplane mode periodically.
