[Q] Completely lost my signal/radio. Advice anyone? - T-Mobile Samsung Galaxy Note 8 Questions & Answers

Out of nowhere my signal just disappeared. No bars. Just an x inside the area. I can't search for networks, find networks, choose networks. Nothing. I restart the phone, and it works for about a minute, then it's gone again. Strangest thing I've ever seen. I've toggled airplane mode, restarted the phone multiple times. I've reset network settings. I'm at a loss. Not rooted. Nothing out of the ordinary. About to hard reset and see what happens.
Any one have anything similar happen? Complete first for me since I've ever had a mobile phone.

And sure enough, a hard reset did the trick. Such a pain waiting on the restore. At least it wasn't something I had to send it back to Samsung.

phone restarts continuosly

Hi,
School just started today and we have wireless at school, so i tried to connect to the wifi with credentials and so forth.
I have Proven Rom 1.08 and all the other reg stuff on it. Did nothing wrong at all, but soon after trying to connect to the wireless network, the phone restarted and now its in a continuous loop of restarting. It doesnt stop, I have soft resetted the phone multiple times. I dont want to hard reset it right now since I havent backed up anything. Please help me. I dont know what else to do. I have also removed the battery and put it back after a few mins to push me luck.
P.s. When the phone starts, the first screen, The ATT world phone screen comes on, the phone vibrates, and then a blank screen, and the phone restarts.
Well,
I went with the hard reset, removed my mem card and sim. The phone seems to work as before, but I hope I havent stumbled upon an issue that could appear again.

More wi-fi problems

Got an AT&T Titan today.
It seems to have wi-fi problems. I've connected it to my wi-fi network but frequently the phone refuses to *re-*connect to it. It can see the wi-fi access point and shows it with full signal strength but "forgets" to reconnect. When I tap on the connection in the list in wi-fi settings it will usually connect but sometimes will put up the popup saying that it could not connect.
I do not have this issue with any other device on the network (and I have many). I suspect that this related to the issue being reported on the other thread in this forum, that the phone starts to prefer 3G over wi-fi even when wi-fi is connected. There's a similar issue with the Radar.
Anyone find a way to work around this, maybe with some magic settings on the wi-fi access point?
Edit: maybe my AP? I'm trying a different one to compare.
Exactly the same problem here.. Wifi is unstable as hell, when it's been on for some house.. You never know if and when it's gonna connect again.. HTC drivers
No problems with WiFi here. My connection is always stable even when switching to other networks.

Update: I've done a few things with my wi-fi AP and at least one of these measures seems to have helped, as I've not seen the problem since:
* Turned off 802.11b/g/n, turned on 802.11g only
* Turned off QoS
* Changed wi-fi channel to 5
* Added a second AP also set to 802.11g only (same SSID, channel 8)
According to the phone's wi-fi signal strength display I shouldn't have needed the second AP, but with it I definitely have a much stronger signal all over my house. BandWidth shows a speed bump from ~5M to around ~10M.
So maybe the Titan is very sensitive to signal strength? Or doesn't like 802.11n. Or maybe it just doesn't like the Belkin router I have.
I'll be trying this at work tomorrow to get even more data points. I use this thing on GoPhone and so non-reliable wi-fi --> the Titan is going back.
This seems to be a common bug. Mine is doing the same. It can be helped by disabling the data connection in mobile settings while you want to use the WiFi. Not a solution, more of a workaround but it bodes well for a software fix I'd guess.
I think this phone's wi-fi is working but is extremely sensitive to fringe wi-fi signal and/or channel interference.
Since I added a second AP in my house and adjusted the channels to avoid conflicts with the neighbors (using a wi-fi analyzer on a tablet), I have not seen this at home.
At work I've only seen this happen once, and it was near a doorway (where the wi-fi signal presumably is at its weakest in the building).
Mine seems to have developed this problem after installing the latest update from HTC (still on 7720). This happens even with the 3G turned off..
Hopefully it will be fixed in the next update because it is quite annoying!
hard reset makes a difference
so i spent a bit of time with htc support. they recommended hard resetting as others had warned me. in the end i got so fed up with it i tried it and actually the phone is much better on wifi right now. i totally cleared out zune too and reset everything i could think of. one thing i had on before was wireless sync. decided not to bother this time. no idea if it's the culprit but are you guys having problems using wireless sync by any chance?

I have also been experiencing the same issue with the AT&T titan. My old Focus works great. I know that HTC had some problems with the using spoofed MAC addresses and maybe the fix has something to do with it. HTC is a great company, but it seems to take them a few versions to get their code clean.
I manually pushed 7440 to my phone and I am not sure if it is related, but I have not experienced the WIFI issue since. The patch does not mention anything about WIFI and since it is likely a driver issue, probably a wild goose chase, but...

I take it back. Just got home and the problem still exists.

The problem persisted for me too after 7740. Still behaving at the moment after the hard reset. Fingers crossed it stays that way.
Guys the definite solution to all connectivity issues, marketplace and sharing issues can be rectified by hard reset. I know in absence of back up apps it might not be the best option for some. But guys that has solved my ever I going issue with marketplace downloads. Also I realised real performance update that came along with 7740 update only after the hard reset. It took me an hour to re add all my 8 accounts, sync back my photos and music and re add my 131 apps but in the end I am problem free and super smooth since last 29 hours. Oh and if you do a hard reset then don't add windows live ID during phone set up. Do it without id and when it loaded, restart phone. After one restart add live account manually. I think that saves some sort of log file corruption.

Hard reset does not solve the w-fi issue being discussed on this thread.
The Titan is very sensitive to signal strength and sometimes refuses to reconnect wi-fi because if that.
My WiFi password key index was set to 2. But I cannot figure out how to make this happen on my Titan (maybe all WP7 device is the same). Yes I can change the key index to 1 on AP but that means I have to reset all WiFi enabled devices.
Any suggestions? Thanks.
I've had my AT&T Titan for a couple of days and am definitely having this issue. My wi-fi connection does not hold, and when I look at my phone it is often searching to connect back to the wi-fi network. It always connects, but it doesn't seem to hold the connection. Which means it must also be draining battery? I switched from the Focus, and I never had this issue with the Focus on the same wi-fi networks. I am running OS version 7.10.7720.68. I'm not seeing any solutions here, am I missing one?
Wifi issue
Have the same problem Love the phone but this is worrisome. Heres the response from HTC rep:
We are sorry to hear that you are having wi-fi issues with your Titan.
This is not an issue that is currently under analysis for this device; therefore, please try to resolve the issue by performing the resets of your device.
Soft -
Pulling the battery out is generally referred to as a 'soft reset'. Please turn phone off, remove/replace battery and then turn phone back on. If this does not correct the issue, then please ensure that your personal information such as contacts and photos have been backed up in preparation for a factory reset. Resetting the phone deletes all data, including downloaded applications, and resets the phone back to its initial state — the state before you turned on the phone for the first time.
Factory -
Performing a factory reset via settings:
Tap Settings -> about phone.
Tap reset your phone, and then tap yes.
Performing a factory reset using phone buttons:
If you cannot turn on your phone or access the phone settings, you can still perform a factory reset by using the buttons on the phone.
With the phone turned off, press and hold the VOLUME UP and DOWN buttons, and then briefly press the POWER button.
Wait for the screen to show the instructions on how to do the factory reset, and then release the VOLUME UP and DOWN buttons.
Follow the instructions to factory reset your phone.

What I think is that I have spent countless hours downloading, installing and setting up all the apps I had on my Focus, and I'm still not done, and I really don't want to do that all again less than a week later.
Tried the hard reset. No luck.
Got another HTC response advising that I remove any cases I may have on the phone. Has anybody had any luck with wireless G v. N?

Tried a wireless G router. No better. I've noticed that when I get it working its just a matter of time before WiFi data stops.

accidentally clicked on turn off radio.

help. i entered the access code *#*#4636#*#* on my karbonn a9+, then accidentally clicked on turn off radio.
i tried to turn it back on but it just goes haywire. it turns on and off and on and off. now i can't get any gsm or any signal on my sim1.
i get a signal when i'm using my sim2 slot, however, i want to use both.
i was fiddling with the phone information for the networks because i am frequently having signal dropouts, and now this. any help would be appreciated.
have u tried factory reset?
before i factory reset, just a quick question.
does factory reset affect the gsm settings? like for example directly to what i stupidly did?
i really appreciate the suggestion, but as you said, it's a guess. i don't want to make matters worse, so i want to play safe and not lose my personal data.

[GT-P7500R (P4)] Tab 10.1 3G stopped working after airplane mode. (CM10.1 Nightly)

I updated to the latest nightly (9/22) to try and relieve this problem to no avail. I've been running CM Nightlies on my P4 since they've been available. I always manually download them since, for whatever reason, Rom Manager seems to detect my device as the P4-wifi. I assure you the 3G (HSPA) modem works. I have a SIM slot, with SIM that has activated service (UMTS/HSPA). My cell phone is on the same networks and it picks up signal from my carrier fine.
With that out of the way; My issue:
Two days ago, I was leaving my house to visit family, and I wasn't going to bring my charger for my Tab, so I put the device in airplane mode to conserve battery. In hindsight, I should have just asked the device to power off, but that's besides the point. When I tried turning off Airplane mode, the cellular network did not become available again; this situation has not changed since.
What I've done: Rebooted the device after switching out of airplane mode, re-entered airplane mode and left it again, updated to the latest CM. I've opened my tab and reseated the connections for SIM and antenna (at least, the connections I can reseat, I have), I've also completely disconnected power by unplugging the battery and reconnecting it. Additionally, I got into some of the hidden menus and verified that WCDMA, which, I believe is the underlying tech for the local HSPA connection, is preferred to the cell radio.
Looking at the device, if I ask it to check for mobile networks, the list comes back blank. The network status shows "UNKNOWN:0" and the lockscreen shows "NO SERVICE." instead of "NO SIM" (which is what it shows when I remove the SIM). From what I can tell the radio has shut off and will not come back on.
Throughout all this Wifi still works perfectly, so the device isn't useless, however, I'm planning to sell this device and I would like it to be as fully functional as possible when I hand it off to it's next owner, so getting this solved is very important to me. Any and all suggestions are appreciated and I'm basically willing to try anything at this point. I feel as though I've tried everything short of a factory reset, which I'm not sure if that would help (I've even wiped cache and dalvik).
In case it's relevant, I'm in Canada, carrier is Telus.
Thanks for reading.
EDIT: I've just finished restoring the device to Stock 4.0.4 (I've used this stock image before when I had issues with the device and confirmed it is fully functional) and I am still having trouble. this points to either a carrier issue or a hardware issue. I will be calling the carrier in the morning, despite believing that this isn't the case. any suggestions on what could be the problem are still welcome, I'm willing to try just about anything at this point.
@Mystik
Back in the CM 4.1.2 days on the e4gt...we had a similiar problem. Now, I don't have you're device. But when this problem arose in the epic. We had a work around where we would turn airplane mode on and power off the device. Then power the device back up. When that didn't work we had to flash a modem, then flash back to the one we wanted.
Also, make sure after you turn off airplane mode.. that the mobile data under settings/more is enabled... sometimes it will not re-enable itself.
Let me know if this works.. if not I would be happy to help you search up a fix..

LTE Data Flashing on/off

Just encountered a little problem today. From the beginning: My Note 3 was rooted/TWRP'd running Vision X 3.0. Gave my wife my new G3 and took the Note 3 back. When I wiped her data in TWRP and restored a backup (same ROM) the 4GLTE icon started flashing on and off. I wiped complete again, installed a new ROM and did the same. Then I Odin'd to the new update. Same issue. I did encounter an issue with switching the phones earlier in the day. I had to get Sprint to do it via chat due to the Note 3 not being deactivated/reactivated correctly when I tried through the site. So I am guessing it could be a bad SIM card or they muffed something during activation. It will at times stop flashing and give me full LTE, but if I reboot or shut the phone off/back on it starts flashing again and the phone gets warm. It will sometimes stop/start if I mess with Connections Optimizer too, either checking or unchecking. Appears to be trying to connect to LTE but something is preventing it from locking on. I would appreciate it if anyone that has run into this before can give me some ideas. I do have a service center in town, and will go in the AM if I cannot find a solution anywhere else. I have never encountered this before.
Also in settings for data, Mobile State flashed between Connected/Disconnected and Mobile Network Type flashes between LTE/Unknown along with the LTE icon in status bar.
Tried killing data and all that. Airplane mode etc.. Sprint service center says it may happen when updating and will calm down in a couple of days..I don't think it was the update since I didn't update until after it started.
Also failed to mention when I switch to CDMA only in Data settings it will stay on 3G and doesn't flash. Has to be an LTE issue. And it is not the towers in the area because the G3 is fine.
Since it's broke anyway, going to Odin NC5 and see what happens. Tried freezing Connections Optimizer and flashing a new Kernel but didn't work either.
EDIT: Nope. That didn't work either. Ugh
Apparently it was a Sprint issue. Had to let it ride for a day or so and now back to normal. LTE is good again. Was an issue on their end when something went wrong during the phone swap.
Had this same problem with my Galaxy Grand Prime and rebooted in safe mode and it stopped. Safe mode disables all 3rd party apps. It is a 3rd party app causing the problem. I had to turn phone off, turn back on and hold volume down button after seeing Samsung logo popup, then wait for the safe mode to appear in lower left corner and release the button. Flashing stopped after that. Turned safe mode off and its still good so far. Hope this helps someone!!
