Hey guys i have had some issues with my cell phone lately (hd2 tmous).
3-4 times a day i lose my signal completely and the only way to get it back is to restart the device. Sometimes my device even displays
I have tried using different radios as well no luck
that the simcard has been removed, i have tried everything
also it happens whether im at home, school or work, i live in an area that gets great reception so that should not be the problem.
messing with the band to keep it at gsm only
reverted back to auto
removed and replaced sim card
hard reset, new rom, stock rom, i always task29 before new rom as well
does this happen to anyone else, any ideas on what the problem may be?
A factory reset with formatting the memory is on the cards I think

i just received a new sd card and it used to happen with my old formatted one, im not sure that would work? although it wouldnt hurt to see if it happens without the sd card in it.
It happens to me. Maybe a few times a week, though it will regain signal after a minute or few minutes. Sometimes I toggle the phone option off/on. Maybe that helps or maybe not. Rarely do I have to power down the phone, though I have done it a couple of time when I'm in a hurry.
It used to happen more often with the stock ROM from April of this year. Since I've upgraded a couple of times, it's gotten better. Hopefully the latest 3.14 ROM has fixed it some more.
have you complained to tmobile??? Maybe you need a new phone.

Browsing between topics of the H2 this one came to my attention.
I have exact the same issue! I also had it with my htc diamond. I moth ago when I received my HD2 (non branded) I thought it would be over. But no. it keeps losing signal. Freakingly annoying. I called tmobile (Netherlands sins i am from the Netherlands) and they would send me kindly enough a new sim.
But still…. The same issue.
I also did a hard reset, new ROM (cant go back to 1.33) and tried another phone. I gather it is a htc issue and some bad luck.
I didn’t had the error sim removed.
ok so i went about half a day with the sd card out and when i woke up this morning no signal again.
I gave t-mobile a call and explained to them what was going on. I was transferred to a pda/smartphone specialist, although i would say that any xda community member was more knowoledgeable than this rep. Anyway she asked me a couple of questions said there were no known issues and that i will receive a replacement phone and sim in 7 days and to return the old one phone. Hopefully with the new phone and sim i wont have this issue, im guessing they think its a hardware related problem. It bugs me that cheap crappy phones have no problem holding a signal and my top of the line hd2 does but lets hope had a faulty connection or something.

Your problem (most likely) lies with a bad combination of Rom and Radio.
I know you have tried several radios, but you simply missed the compatible one.

apart from my provider having problems every now and then, I have not lost my connection again after flashing the right Radio.

i have tried both the 2.13 stock rom radio and then the stock 3.14 combo both did not work.
resolved
received the new phone 3 days ago, so far have not lost service. It must have been a hardware issue with my phone. im using the same radio rom as the old phone except no signal loss, for anyone who is having the issue it may be worth calling tmobile to exchange your phone for a new/refurbished one.
Let me start off by saying that this issue started back at the beginning of Dec 2015. I've had the phone since winter 2014, and for a year, it was the most amazing phone ever. However, one day as mentioned beginning in dec 2015, the phone began running extremely slow and was restarting frequently. I assumed it was a just a OS issue, and so I did a system factory reset. However, the problem persisted even after a reset and cache clearing. So I called up Samsung, and then told me to send in the phone to get looked at. Since then...I have sent in the phone 4 times to get looked and each time, Samsung has said there is no issue pretty much. I've tried phone with different new batteries, and the same problem still occurs.
The oddest thing that I've noticed with this issue is the phone runs smoothly and flawlessly, when there is no SIM card inserted. But, as soon as I insert my At&T sim card into the phone, all the lagging/restarting issues occur. It's been a frustrating 3 months trying to deal with issue, and i'm at the point where i'm throwing in the towel and calling it quits on trying to fix this phone that costed me so much money.
At&t reps were clueless when I brought this issue to them today, and told me to call samsung....even though samsung says at this point it's a network provider issue and that I bring it to At&t. I've googled this issue and couldn't find anything on this. Posting on here is my last ditch effort, and if anyone knows anything that can, I would very much appreciate it. If not, i'll prob buy a new phone out of pocket.
having the same issue since 2 days after sim change
Hi, I recently switched my carrier and inserted a new sim. Phone worked fine initially but after 1 day it has started working extremely slow. It sometimes does not wake up from sleep even when i press the home button repeatedly. Sometimes it hangs and then gets into bootloop. I factory reset my phone yesterday and the issue resolved initially but when i installed and restored my watsapp messages, the issues started all over again. Now i am thinking of flashing my phone with a different ROM and see if it helps.

thanks dr. geek, keep me posted on how that goes.
Problem persisting even after flashing a new rom
I flashed a 5.1.1 australian ROM downloaded via sammobile. but the phone started hanging again this morning. I am beginning to wonder if its an hardware problem.
I have the same problem ...
Have had my Note 4 since November 2014. And it havebeen working flawless, running rooted and everything Until yesterday when i was just casually using my phone and it started to lag and restart, no difference whatever rom. So i tried for a whole day to get it into official firmware with alot of error messages in the progress about the internal memory etc, i ended up repartitioning, and modifying my PIT-file until i finally got it working. And the same issues did still exist. Now the thing that seemed to work for me was to change battery, now it seems to run again without lagging, or anything. Tho it wont restart properly without restarting twice by itself..

Hi, i doubt it to be a battery issue. Anyways, i would really appreciate if u post an update again after 1-2 days. i just want to confirm it before spending money on a new battery.

Hey yeah, well. you're right. I only got up to 3 hour use before same problems started to occur again. I have officially given up now tho, it must be a hardware failure. Im going to send it in.
its the EMMC chip bug

I am also getting a black screen sometimes before booting which says "ddi EMMC error". I think my nand chip is corrupted. Is any one of u getting the similar error?? Also flashing my phone with a PIT file can solve the issue ??

Im getting the same, i guess you could try it. But from what ive read it seems like the only fix is for samsung to exchange your phone, or change motherboard.
Good luck with samsung fixing it. I sent it in 4 times and each they responded "no problem found". I gave up and bought a moto e.

Yesterday i flashed my phone again, this time with a PIT file and repartitioning checked. Eveything went fine but the phone went into recovery booting bootoop initially but started on its own after a few bootloops. It worked fine for sometime, but when i entered my samsung account and it started to restore my msgs, call logs and apps, after 1 hour or so it started to freeze all over again. I am starting to think that some app could be a reason too. Now i will flash again and keep using it without restoring my old phone and installing only a few essential apps and see what happens

I also installed an app from the play store EMMC brickbug check but it says that my NAND chip is sane (fine i guess)
Same happens to to my note 4 snapdragon phe.
Any updates ? Did anyone got it back fixed from Samsung?
Good luck
My T-mobile Note 4 started experiencing this same issue last week. Is this a coincidence or something more? For everyone with the same issue, has your phone been slightly warmer at the top?
I purchased a new Anker battery to see if that will resolve the issue and will test it when it comes. But I think the emmc is starting to go bad? It seems to work fine without a SIM card inserted also.
I just received from samsung that they need to replace the motherboard, and of course the warranty isnt covering up since i rooted it. And they're going to want 540 USD from me to do that. Sigh, last phone i bought from samsung for sure.
Hey xda techies and guru's, i need some major desperate help here...
This is going to be a long read, but its for the sake of understanding and what exactly is happening, I hope you read on and hopefully have an idea as to what's going on.
So i've been a Rogers customer for the past 7 years, i've been using the Galaxy S3 for 4 of those years using the same SIM card. Just recently, I decided to upgrade and purchased a Galaxy S5. I put my new sim card in the S5 and everything was working flawlessly for about 2 months and then one morning I was sending some texts out, and didn't receive any all day so i checked my texts and realized they did not send. I then tried to make a call and got a message stating "not registered on network". So being the troubleshooting/techy guy i think i am, i go to google and start trying every solution out there. I got so desperate at wanting to fix this issue i had eventually factory reset, and even stock rom flashed the phone...but nothing i tried or did seemed to fix this issue. I put my sim card back in my S3 and it seemed to work just fine, so I figured nothing was wrong with the sim card, it had to be the S5...so here i am out of solutions to try, i randomly grab my brothers sim card from his phone and put it in my S5, and to my surprise it worked! so i thought that maybe the sim card was actually at fault. so i go to my nearest rogers store and get a new sim card, low and behold it's fixed!!!
...a week later, my phone decides to repeat the same ordeal. "not registered on network", so i go back to rogers and get a new sim card again, seems like it fixed the issue once again. and then a week later, same thing happens yet again. at this point...my phone has a temporary fix, but is way to unreliable as i have no idea when this starts happening and can miss very important phone calls or texts. So now this happens again the other night, and i put the sim into my S3 for a couple hours, make some calls and then for the heck of it decide to try it in my S5 again, and it worked! but it worked for maybe 16 hours until repeating the same thing. so i pop it back into my S3 make some test calls, and put it back into my S5 and now it's working again...for how long, i have no idea...fact is it's unreliable and i hate always having to check my phone in paranoia that this may happen again.
what do you guys think is the problem here? Rogers is willing to help me get it serviced for free. but i feel like they won't find the issue with the time they are given with it...
desperate need of help/advice. thanks!
so this is the second S7e and second SIM that I have been having this issue with. The phone will lose connection to the mobile network and the ONLY way to recover is to reboot phone. Reset Network Settings doesn't do anything. Toggle airplane mode doesn't do anything. Search for Network Operators doesn't do anything. I have a third phone on the way - but has anyone around here heard of or experienced similar? Am I missing something that I should be doing to correct this?
Thanks in advance
I too have this problem. Got a replacement refurbished phone under warranty and the phone has this problem

Did you pay the $20? I didnt want to pay the 20 so i sent the device to samsung. Should get it back friday or monday. The issue is definitely phone related. Im using a verizon s7 now and no issues like that arose. I even tried new sim.. My father is having same issue t-mobile s7 edge
Yes i had to pay 20. And it's disappointing I am having this issue with the replacement phone. I am having this problem on the U firmware as well.

I've suffered the same issue from time-to-time and just do a restart....annoying as hell to be honest
Are you guys always in the same location when this is happening or is it just whenever and wherever? Or is it happening a one certain place where cell signal isn't that great? I had this same issue BUT only in my house so I had to get a network range extender from t-mobile to use at home.
This happens to me all the time. It's so annoying. At work, in the car, at home--it doesn't matter where I am. Have reset firmware multiple times and even rolled back once too. I think it has to do with the latest software because I never had this issue before the Fall/Winter. Hopefully Nougat fixes this!

I happens randomly in different places. For me i lose complete signal, and then only get back signal without data. I have to restart when this happens to get back data. Annoying as hell !

I am having the same problem, this will be my 3rd phone 4th sim. I wish I knew how to fix it
I would try flashing different radios/modems, its worth a shot. Maybe try flashing the "U" firmware radios.
Nougat will fix it
My wife and I had the same issue on our tmobile s7 edge ... we got the 7.0 beta and now the issue is gone .... I bet it's radio and software related ... 7.0 will be out by the end of the month hope that helps...
I had this issue with my phone, and it was a huge pain. The biggest concern: I didn't know when my phone was off network (voice, data, etc.). The fix, for me, was simple: a new SIM card.
You may have an issue from a rejected permission on an app.
Had the same issue before but I did a hard reset and realised that I changed permissions on an app that wasn't written for 6.1.

I hope so! Been waiting for that before I try anything drastic, even though this issue is a huge pain in the ass. I'm glad others have come out of hiding to express their concerns with it as well. I thought I was the only one for the longest time having this issue.

Many of us have tried new SIM cards, but it's worth a shot if it's still not working consistently after Nougat is released.

My and my friend's phones are both running pure 100% OEM Tmo stock without any apps disabled or touched at all and we have this issue and have done multiple resets. Pretty sure it's an actual hardware defect, or hopefully just a software one with the modem/radio.

I was thinking about going that route. But I wasnt sure what condition the phone would be. How was you condition?
I sent mine to samsung and the things they replaced is the Coaxle cable "antenna" replaced 3 of them. I have been using the s7 from verizon on the U firmware so havent seen if it is fixed.

I received a refurb. Other than this problem, the phone is alright. I noticed this problem on receiving the phone it was running on T firmware. Then I switched to U firmware and radio but no difference. I called customer support yesterday, they said to go to a retail store to get the phone replaced. My worry is going through this process again and if I receive a bad device again what to do? After all refurb phones are like playing Russian roulette!

I just had this start happening on mine... I really wish they would release nougat already. It is ridiculous they won't post an Odin flashable version of the release candidate if it does indeed fix the issue.
I also think its a specific tower configuration that is causing the issue that the radio can not understand. (Maybe 3xCA). Its happening in the same areas every time.
I just started having this problem in the past month. All at once I've been getting BT sometimes turning off, mobile networks failing to reconnect after I visit a no/low signal area (such as after a plane trip when the phone was in airplane mode). I've also seen wifi mode fight my attempts to turn it back on sometimes - toggling itself on and off a couple of times per second until I poke at enough settings to stop it. When BT turns itself off I have trouble turning it back on, sometimes it just goes back on, sometimes it refuses after a number of tries and if I wait an hour it goes back on just fine.
The folks at a BB Samsung kiosk said they could reflash it if I wanted to go that route, but that the nougat release would be out soon so it might be better to just wait for that. Has anyone had a Samsung rep re-image their phone to try to solve this?

If you were able to fix without a reboot you didn't have the same issue as this.

I guess I wasn't clear about that as I have several problems that are probably related, but behave a little differently.
BT dropping - can usually turn it back on, but sometimes it refuses. Usually don't need to reboot to fix this.
Wifi dropping - often have trouble turning it back on and have seen the widget toggle off and on repeatedly by itself. Sometimes have to reboot to fix that.
Mobile Network data (and voice sometimes) dropping - usually have to reboot. I think I may have recovered that once without a reboot, but the other few times it's happened in the past month since it started I have rebooted and that fixed it in all but one of the reboots - one time I rebooted and still had to fiddle with it a bit after the reboot before it came back. That may have been because I played too much with the network settings before the reboot and so had to undo that damage after the reboot. But, definitely rebooting is a fairly reliable step in fixing this problem.
All 3 started happening around the same time which is why I thought it was a software issue (I remember a small update a little over a month ago, but forget the details of it). It's nice to hear that others also have the mobile network problem, but if that is isolated in those cases then maybe I'm not seeing exactly the same problem. But, it is clear that rebooting is almost always required to get my mobile network data back so that again suggests that at least that part is the same as what this thread is discussing.
In looking at the T-Mobile updates page for the S7 Edge I see that the version I have (G935TUVU4APK1) was updated in early November - which tracks when I started having problems, and it includes a fix for "Domestic data roaming improvements", which definitely sounds like they may have played with the radios.
I am so ready for the Nougat update...
I've tried everything to get my phone to get network working again. I've re-flashed old and newer images, got a new sim, messed with the APN settings and I just can't get it to work since yesterday.
When it started, my phone was sitting on charge. It was working just fine before I had put it down for 30 minutes. Upon checking for any messages I saw it wasn't getting any service so I restarted the device and was greeted with the 7.1.2 july update installer. Waited for it to finish and once fully back onto the home screen for a few minutes service still never came back. Turned it off and on a few times and turned airplane mode on and off few times still never came back. Turned it off for the night till today when I started playing with it more, factory reset, flashed 6.0, 7.1.2 june, 7.1.2 july, O beta 3 and none of it was getting the network to work.
Went and got a new sim, guy at the store also tried a floor sim and none of them were working but both my old and new sim do work just fine in a backup phone. The 6P reads there is a sim in and it knows its AT&T, but it won't pick up signal at all.
Any help with this? There really isn't much on this topic, but I do see a sim card no installed issue which my phone knows there is a sim card in it.
that happened to a nexus 6p i bought from a guy off craigslist. at first it worked with tmobile and metro pcs then after a few weeks it stopped working but i had switched to cricket anyway and it worked on cricket but not on tmobile or metro, so then i checked imei and it was black listed,.... being that it was a BYOD it wasnt bound to any network so i was like why would it be blacklisted... didnt make sense but i stayed with cricket and to this day it works..

I just checked to see if it was blacklisted and its good. Google & Huawei won't service it due to it being out of warranty so rn its pretty much a dead phone for me. Is there is any tests I can run to see if the network radios are working or even turned on?
I had this exact same problem a few months ago with my other 6P. Thankfully it was right before my warranty ran out so i was able to get a replacement, but as far as I know, there isn't much you can do with it network wise.
@MadBullBunny could it maybe be the antenna inside? If you've tried other carrier Sims and flashed different radios what else I wonder. Since it's not working maybe worth a peak if your comfortable opening her up.

I really didn't want to go that far and I rather just dump it on craigslist for $250 if its just an issue with at&t. is there some sort of test to see if the antennas are working?
have you try resetting your network settings? this has happen to me right after a update and resetting the network settings fixed it for me. i'm on project fi.

Dude... Not trying to be rude, but really?
Anyway I've been waiting for a response back from google. Huawei pretty much told me tough luck since I didn't have warranty left on it. Told google that I was pretty much shoved out by them and argued that a phone not even 2 years old can't get serviced by a multi billion dollar company is pretty embarrassing. Supposedly its being routed up but I was told that a couple days ago when it was going to take 24-48 hours to get back. Right now I'm trying last ditch effort to drain the battery completely and stick it in some rice to possibly suck any possible moisture out that maybe my butt sweat caused. If this doesn't work I'm going to go to other service's stores and ask to try their sims in the phone out.
Fun tip: My phone is been running in boot mode for almost an hour after it turning off from android os for battery being dead. I've been doing random stuff in boot mode trying to make it die completely and it doesn't want too.
So being back and fourth with google for almost a week I was pretty much told tough luck buddy. It fathoms me that a company who created the android OS doesn't even have a service center or require its manufacturers to provide a service center for phones that aren't even more than 2 years old.
My nexus 6p is posted on craigslist and I've bought myself a s8+. so word of warning to you all who buy any google product or from them, just don't. If you have any issues you'll just get a run around. I've had to tell my issue to google at least 20 times and they still didn't care and kept trying to push me to hauwei when neither of them wanted to help.
