Hi, I was using my G935V normally on 4G LTE (like I´ve been using it for more than a year in Mexico´s Telcel Network), but suddenly I stop receiving any signal. I know that could happen for a few minutes but after hours I got worried. I started researching what the problem could be:
1.- SIM: I checked it in another exact same phone, and it worked so I know that is not the problem.
2.-SIM pins are probably fine because the phone shows the "SIM card is not Verizon..."
3.- I tried restarting, also wiping cache and the factory reset. But nothing works.
4.-Apparently the IMEI is fine (not null or blocked)
5.- I tried to use the verizon update assistant but didn´t work too. It stops like at 83% of repairing and then it shows that the device was disconnected. (I have tried this several times and the same thing happens again and again)
6.- I downloaded the "Hidden settings" app to change the radio info, and I noticed that the "radio is off" (so i guess this is the real problem) but every time i try to turn it "on" it goes back to "off". It does not allow me to change the "preferred network type" (it says unknown).
7.-I have checked some posts that propose to make something to remove the "static charge" off the phone but you have to remove the battery (and like probably every body here knows you can´t do that with the s7).
8.- I don´t know why but it looks like the airplane mode is on because the icon is on, but settings says it is off.
So if anyone has a different option that could (and fortunatekly would) work, please write it. Thanks for your attention.

I fixed the problem by flashing an unlocked ROM from Sammobile (from G935V to G935U). Seems to work fine and you get rid of the bloatware (got some people a Win/Win situation)
i have had the same problem for 2 1/2 years. leave the phone for a while until it's the battery goes dry . when i charge it again it comes back with the signal. it works fine until it is restarted if you power it off it back to no signal at all.

by the phone indicator I mean the reception status indicator. after I wake from sleep mode it would not show any reception status at all. I cannot go into phone settings after that, would tell me wait 15 seconds then try again but after 15 seconds, same thing.
I can use the phone however, calls would connect and incoming calls would connect.
a related bug that I noticed, I cannot disable flight mode properly either. after entering flight mode phone shuts off (normal) but when I wake it would not come back alive. phone indicator remains with an 'X' on it and I cannot force it to register on my network.
running on Rogers Wireless in Canada. although I doubt the network is causing this grief.
anyone else experience this? so far there's only 1 ROM version available that I'm aware of. so I don't think that'll have any effects on this.
suggestions would be appericiated.

btw forgot to mention I'm on an I-mate K-JAM.
all else set aside this is an excellent device. being my first pocket PC I know I will have a great experience playing with WM5.
I have tried manually setting all sleep options to 0 with PHM regedit. that includes BT and phone.
in case any fellow Canadians are wondering about the availability of K JAM in canada. the answer is NO. I had to order it from a US store, paid a fortune clearing it from the customs and waited 2 weeks for shipping. tough luck being a Canadian .
Yep, this happens on mine as well. Sometimes it goes so far as to say "SIM status unknown." I hope a ROM update can fix it.
I have had the same issue on occasion... Not sure if it 3rd party software doing it though... Don't want to hard reset just yet...
I could not exit flight mode one time. Soft reset fixed it.
somewhat of a fix. I just turn power off after 3 min thing off while on battery. manually lock keys and turn screen off everytime I finish using the unit. the battery definitely sucks a whole lot more but phone don't go to sleep anymore which fixes the whole not recovering reception issue. and flight mode seems to work better as well.

Same here with my Qtek 9100. And my 9100 continues to show the roaming icon even if I am under coverage of my home network (Vodafone Italy). I think that this one is a SIM related bug (I tried to use another SIM and everything was fine), waiting for the next ROM update.

I just received my touch HD yesterday and found an annoying bug when I was trying to disable 3G (since I am in the US). Maybe I was going about it wrong, but here is the problem:
* When I disable HSDPA/HSUPA in the connection settings, WinMo will infinitely reboot.
I searched but the only infinite reboot problems I found were related to the colored task bar.
This isn't a huge problem, I just won't disable that anymore, but I thought I would let you know since I didn't see anything about it in the forum. I could have missed it though. If this is a re-post you are welcome to delete it.
That's interesting.... by infinite boot do you mean, it keeps rebooting and not letting you do anything until you do a hard reset? I too am in the states and have disabled that option, and I don't have problem. However, what does happen (and I haven't seen anyone post about this, maybe because they haven't figured out why it's doing it yet), is that the phone reboots when it looses signal (I'm pretty sure of this, as the only time my phone ever reboots itself are in three exact locations, where i get 1 bar max). I'm not sure if this is related to the Data connection either (as I do use one). I'd love to see a discussion => solution on this problem.

YES! I think you have solved my reboot issues!
I also live in the US and on some downtime I was fooling around with my HD and also discovered where I could disable HSDPA/HSUPA and thought since it is not needed and may use resources/power I turned it off. Sadly I started getting reboots during what seemed like weak network connections (1 bar or less). I have a few tweak programs and have changed several settings but didn't know where to begin, and would not have thought about turning HSDPA back on, to figure this one out without hard resetting.
Thanks for your post! I will turn HSDPA back on and hope that solves my problem.
Did you happen to notice if it wanted to do it with low network signals?
Regards,
Gordo
Well, I turned both of them back on, and let you know if it will get rid of the 'random' restarts
Yes, it would infinitely reboot until I hard reset the device.
It would boot most of the way into windows, load up TF3D, then reboot.
I have hard reset about 3 times today, everything worked fine each time until I disabled HSDPA/HSUPA (via Start->Settings->Connections->Advanced Network)
Each time I hard reset, I didn't install any programs, just disabled that setting and... boom infinite reboot. (Everything worked fine until that setting changed. Phone/SMS/...)
EDIT: @Svegetto - For me they weren't 'random' reboots, it was a reboot loop.
My Device
CE OS: 5.2.20757 (Build 20757.1.4.0)
ROM Version: 1.14.405.3 (22273) WWE
Radio: 1.09.25.14
Protocol: 52.49a.25.26U
In case it matters...
I was getting the same thing with a weak signal. I was in a hotel where when I got in the elevator bam, it would reboot. Did it pretty much every time.
I was in another location where I was not getting any signal and it was stuck in that same reboot loop. After noticing it would happen while it was trying to locate a signal I removed the sim card and it would reboot fine. Until now I was leaning toward a hardware problem (that I didn't cause) that may have involved the cellular radio overloading the system during a weak signal when it is throttled at max power output. Good radio signals cause it to throttle back to save power so I was about ready to send it in for repair! I even tried a different sim card, SD card, and battery with no change. Now remembering that I did turn off that HSDPA setting, and have since turned it back on, I will be hopeful that my problems are over!
This site is great!! Thanks guys/gals!

Reboots
WOw.. i never thought i would find a thread.. i thought i was the only one. Everytime I get on a plane... and thats a lot... when i arrive at the next airport... searching for signal and then reboot loop... infinite frustrating reboot loop.... solution... take out sim... reboot... clear storage.. insert sim... restore from week old backup...
If this HSDPA thing solves my problem.. i will buy someone a beer.
Well I have just 'tested' the 'random' reboot at one of the spots that it would normally reboot, and no reboot (although I've never experienced the infinite reboot, mine would usually reboot once, than maybe a second time, but I'm confident to say that it was due to the HSDPA/HSUPA setting which is really funny cause for the past 3 months I've been waiting for someone to post a thread on the topic)
But yes, it would seem that even if you're in the states and will never get to use it, leave HSDPA/HSUPA enabled (or if someone feels like doing further testing to find out if it's just HSDPA or HSUPA that causes this issue, or both)
Well done all around!

USA Touch HD Users-Beware!
For what it's worth, turning HSDPA back on totally fixed the reboot problem. It has not happened a single time since doing that.
For anyone doing a thread search to troubleshoot this problem it is under:
Settings - Connections - Advanced Network - HSDPA tab
If you were so inclined, as I was, to turn it off thinking it might save battery life or something, don't do it! Low network signal strength will cause it to reboot.

Gordo
Yes re-enabling HSDPA/HSUPA solves the problem. I started a thread on this last week when I first got my HD:

And here goes some others with the same problem:

I love this site!!
I've been having the same problem and it makes sense now, everytime I phone would reboot I had almost no service. I don't know why I didn't notice the pattern.
So, my brother and I have been running MoDaCo 1.1 core for a couple days now.
My phone has stopped connecting to the mobile network. All it says when I try to connect is "Standby for connecting to mobile network" with a green checkbox. I also notice now when I select the checkbox to connect it turns green instantly and shows that standby message. Before it would take a couple seconds to connect and turn green.
I have tried changing the mode of operation and it still doesn't want to connect. There is no 1x or EVDO in the notification bar. Wifi and GPS still work fine.
My brother's phone is still working fine. I have no idea what the problem can be.
Anybody else having this problem with MoDaCo 1.1?
I think that it has something to do with airplane mode. I enabled airplane mode yesterday, then turned it off. I didn't realize my data wasn't working after that since I don't use it while I'm at home. I am not sure if that is exactly the problem, just trying to think about how it could have stopped working.
I've noticed mine will do this at random on the MoDaCo 1.1 ROM. Every now and then I'll look at my phone and realize my EV symbol at the top is gone and I have no network connection. When this happens both the option in Settings and the small on/off widget on one of my home screens say it's still turned on. If I turn it off and back on, then I just get the "Standby for connecting to mobile network" message too. The only way I've found to get it to work again is to reboot the phone.
FYI this same problem happens to me with the stock ROM, even when it wasn't rooted. I've noticed it only happens when you turn airplane mode on, and then off.
Hmmm...I never touch airplane mode and I never saw this happen once in the month that I had the phone with the stock ROM. Maybe my problem is unrelated then.
Even when I reboot my phone it still doesn't work. I have tried messing around with the widgets turning things on and off multiple times and still nothing can get it working again.
I just went back to an old nandroid backup from before I put MoDaCo 1.1 on the phone and it seems to be working again. I'm going to put 1.1 on again. I'll use it for a while and try to recreate the problem to figure out exactly what it is.
Sprint/HTC has to fix that. it's a bug.
Guys,
I updated my tab a few days ago. Now the market looks different but unfortunately I'm facing another irritating problem which I have no clue how to solve.
Every time that I turn off the tab, and let it be idle for 10 minutes, when I turn it back on, the WiFi icon will show no bars - which translates into no internet connectivity. That happens while the WiFi button is still pressed (green in the pop-up menu). In order for the device to connect to the net I need to turn the WiFi OFF and than ON and it works.
I checked the WiFi sleep configuration and they are set to "never turn it off" I also rebooted the device but with no change.
Please let me know what to do... as this thing sometimes just drives me crazy.
Thanks.

Flash a custom rom bro. Otherwise you are stuck with Samsung's awesome bugs. If you don't want to flash a custom rom there isn't really much you can do about it considering you're not rooted. What did you update to? KMP???
I did the regular Samsung update -the latest one that was released a couple of says ago. The problem with rooting is losing the coverage I have for insuring the device... which I'm reluctant to do. I'm sure it has a solution somewhere...
Yes I confirm.
This "reconnect" issue is being discussed on many forums with no solutions yet. (except custom ROM)
Hello,
First of all, I have never rooted my cell phone, so I guess I am still using the original ROM? I have no idea how to change a ROM, how to root a cellphone, or how to even see what mine is, just so you know. This is why I created a new thread, the other ones solutions always reffered to "change your Rom" etc.
I currently possess a HTC/T-Mobile MyTouch 4G. The issue that I'm having is the following: Everytime I try to turn my Wi-Fi on, it takes a little while, turns on for a couple seconds and then turns itself off, without any command. And it keeps going on this cycle: turning on and off (it is so fast that it cannot even recognize any saved networks, and the wifi icon does not even show up in the upper bar), until I rapidly and manually click, when it is "on", to turn off. Then it stops the cycle, with the WiFi turned off. This means that I cannot use my wireless connection, and it has been lasting for more than 2 months by now. I can access 3G normally. I have tried to "soft format" the cellphone, but it has changed nothing. (By soft format, I mean the format option included on the phone. It formatted everything, deleted my contacts, apps, themes, configurations and etc, but it was made from within the phone). Also, when it is "on", and when I click in the "Wi-Fi settings" bar, it shows nothing and it freezes the phone for a while, some seconds. Then it turns to the "off" state and returns me to the previous page automatically.
The problem aparently appeared from nowhere, I have not made a single change in anything other than installing applications. I have had an issue regarding its battery, though, which made me substitute the battery. The problem also seemed to appear with the battery issue, but it is still occuring, even though I have substituted the battery.
I thank you very much in advance, and look forward for help and a solution.
Best regards.

My First android phone was a Motorola MB200. The WiFi never worked. Tried soft reset, flashing the stock Firmware via Pc and using wifi fixing appsbut it never worked.
Until i rooted and flashed cyanogenmod.
The Wifi miraclously started working.
Until now, i dont know why the stock rom couldnt fix that issue.
To cut things short, you could give rooting a try and it might fix your issue.
