Radio randomly goes off

Hi,
Wondering if anyone is experiencing this issue.
Got the uk version of galaxy nexus, GT-I9250 ordered from an online store from the us. Only within the first 24 hours I experienced a time where I suddenly lost my 3g.. the signal bar shows no service. Only way to get back is to reboot phone.
After it happened few times and doing some testing, it turns out the radio just shuts down. Going to settings, about then status shows radio off. Going to the secret menu that gets accessed by typing a nmber also says radio is off. There is a button to turn radio on.. but it does nothing.
Tried factory reset, .didn't install any apps. Still issue occurred. Also noticed at random time before the total radio sshutdown, I do lose 3g few a minute then comes back.
See my screen captures showing issue attached.
The preferred network type when the radio works is shown as GSM/CDMA auto. During issue its unknown as shown in capture. Changing from unknown to gsm/cdma auto after failure does nothing.
Of course ttried to turm 3g on/off.... airplane mode on/off.. nothing works except a reboot.
I am on Kk1 radio. I didn't try kk6 as i didn't want to touch the phone in anyway to void warranty. my buddy has same phone but doesn't experience iissue. Same phone, same carrier, same city.
Any thoughts?

Maybe exchange it for a new one? My only advice

Have you tried running logcat to see if there are any logs to suggest whats crashing your radio?

Mine done exactly the same as yours and I am with Orange UK who stated I have a faulty sim card and are sending one out in the post to me so hopefully if that resolves mine you can also ask for a replacement sim card as well.
P.S I found that speediest.net knocks wireless/radio off sometimes and also wireless on mine can totally freeze as well so hoping this will be fixed asap by google.

I have same issue - loosing signal completely just with no reason very often. Turn phone off/on - works fine. I have brand new sim card and phone from Handtec, Vodafone UK.

Ditto for me as well. Purchased from Expansys, second round. It will move between 3G and H then shut off. Happened once so far. I'm using a MicroSIM with an adapter, both worked fine and are new.
I'll be watching this very closely. Someone with a Google account can post this to bring it to their attention?
Happened a second time but came back on. Attached a screen shot.

It does happen where the signal is lost, then comes back. That could happen few times before it goes down and then never comes back up at all. I used a program called signal alert to tell me when. It happens. I found that during the day signal is fully lost a number of times but it comes backafter less than a minute. at some point its lost and doesn't come back and only reboot fixes.
Bmstrong, the capture u showed me shows you lost data, but it seems you still have voice. Look at the screen I posted, u can see no bars what so ever in my signal meter.
When the issue occurs, its random, so by the time I find out and i ran alogcat, I would have missed it. Alogcat only shows me few minutrs before. However, I kept looking at alogcat after the fact and there was nothing that i could see that explains this.
I did try another sim while the trouble is occurring and no use.
I have requested rma from where I bought it and just waiting for authorization. Will share my experience with it and the store after.
Thanks,

Bmstrong, go to settings and about, then status to see if it says radio off. If it doesn't then it either your really lost 3g..maybe coverage or a different issue. In my case radio says its off and never comes back.

sorry to post a little off topic. but how do you see the first screen in the OP's post?

I'm getting this issue too, does anyone have any more information or has resolved this?
When going into the phone info screen does pressing "turn on radio" work for anyone? I have to do a reboot before I get signal back.

[Q] Anyone having network issues, radio problems?

I am on my second International HTC one X and both devices would lose the carrier signal quit often... I would either go to airplane mode, or turn the network off and on and it would grab it again. Sometimes it would be good for the day and other times, I would have to do it a few times....
I wanted to think it was my carrier having issues (MTS in Winnipeg MB Canada)... however, this has never happened on my many other devices. Now I wake up today and turn on the mobile data, after awhile... it does not connect, under settings it says disconnected because service is unavailable. I tried reboots, restart, airplane mode, checking apn settings.... on my last reboot, it says No signal/emergency calls only.
So now I am fearing a hardware issue (but I find it odd it happens on both my one xs).
I love this device and aside from this potentially huge issue.... I have no complaints, so I will ask here and see if you guys have any solid input.. before I contact htc!
I also popped my sim in and out, as of right now...
Thx in advance.
**update: it almost seems like putting wifi on, knocks out my carrier signal.... after an hour of doing the above things, I turned off wifi, went to airplane mode and now my signal and data is there (it makes no sense) and it is quite a hassle

The weirder part is, it seems to only be in the morning.... once I am up and running, I do not seem to have many issues through out the day, but If I put wifi on long enough... It goes to no signal/eventually....
If I do not put on wifi, it either does not drop.... or I am not noticing.

I've just begun having network problems but I'm not sure it's related to your situation. I'm in Australia on the Optus network.
It happened suddenly yesterday. Service completely cuts out for extended periods. It will occasionally come back on for a short while (long enough to download all my sms) but will then cut out again. When the signal does briefly come back in, the signal strength is decent: it's an all-or-nothing proposition.
Did you manage to resolve your situation? Would be interested to know what resolved it for you.
I've had this phone since early April when it was released here and the is the first issue I've had with it. I haven't done anything new to my phone in the past week so I'm finding this strange. I'm running Leedroid 4.0.0 but I've had that installed for weeks without issue. I'm worried it could be a hardware issue.
I'm going to try reflashing it tonight to see if it's a software issue.

[Q] Lumia 900 weird issues

I just got a Lumia 900 white and i have noticed the following issues.
The Lumia restarts on its own. It has restarted twice since i got it.
Weird purple screen in low light condition
Rattling sound when phone vibrates. Not like the usual vibrate
Would not connect to a specific router whereas all my other devices can. It can still connect to other routers though
I am running OS version: 7.10.8773.98 and firmware revision number: 2715.1601.8773.12141 which i assume is the latest (tango).
Should i be facing all these issues? I googled around a bit and i found that these issues were previously addressed with updates.
To note, it's an unlocked phone. I can use it with any carriers i want to.
Is there anyway i can re-install tango? I am assuming it's a software issue.
Help please?

Mine never restarted on its own.
I still have the purple screen problem pending a firmware update.
The vibration sound in this phone is like that. All models sound like this.
Never had trouble connecting to any wifi access point/router.

I am having rebooting issues. I think I've narrowed it down to low signal issues. My office is in the basement floor behind the elevators so I'm constantly in and out of signal. I fluctuate between 1-2 bars of 4G or LTE and no signal at all. If I have no signal, it will not reconnect unless I switch it to airplane mode and back. On a few occasions, it has rebooted on me only when I'm at my office. I have contacted Nokia customer support and they wanted me to send it in under warranty. I told them that was useless and that my replacement would have the same issue and told them to try to reproduce the issue with their QA/Dev teams. No response yet.

Mine has shut down twice now for no apparent reason, Always after using Nokia Drive, It was a real pain to start the phone back up too, Had to hold power button for a while, I did think it may be down to signal drops as when travelling the phone has to switch a fair bit I imagine, The phone did get a bit hot so maybe overheating as on both occasions the weather was very warm especially in the car.

no reboot, no purple screen, no ratteling sounds...
but WP7 have some issues with connecting to AP or routers set above chenel 10 (if you are not using automatic). my home router and AP were set at 11 and 12 and my HD 7 could never get connected... and when i changed to lower then 10 it was fine... so now my AP and routers are always set this way.

I have had my phone shut itself down three times now for no obvious reason. That's a bit of a worrying issue if you're on call for work and need people to be able to contact you at any time.

The phone restarting by itself is definitely a weird issue. I never had that happen to me before.
The only weird thing I encountered was the touch screen stopped responding. So I locked the phone and then unlocked it and it worked.
The issues you guys are bringing up here should definitely be covered by Nokia.

Only issue I have is the lumia not syncing contacts to my car's hu...
Sent from my Lumia 900 using Board Express

Yes...
I have had my Lumia 900 for one week, and also had a few a few problems:
1. Two restarts (phone is on, but asks for pin and lock code). Both of which are in a location with very poor/no reception. Both where during the morning (4am and 6am) (can see boot time using a program).
2. Complete discharge, wont initiate charge from computer (think it might have been because I skipped the "red low battery charge phase" (or what we should call it?). Does however charge from a computer if I let it charge with the red battery for a while, then boot it self and after a while it will start charing (with the charge icon blinking.
3. When using the radio in loudspeaker mode, and the screen is locked, after a while (5-10 seconds maybe), it (sometimes) stops, or (sometimes) starts to lag, as if the reception is poor (although the phone hasn't been moved.) pressing the power button, (at slide to unlock) the lag instantly stops. Anyone else wanna test this one? (try a bunch of times, doesn't always happened on mine.)
4. (Pure hardware problem): Rubber gasket between case and USB has been incorrectly paced, and "flaps" in the USB contact. (clearly visible if looking directly into the USB port).
Should I take it back and say I want a new one?
OS Version: 7.10.8773.98
Firmware revision number: 2175.1601.8773.12141

You guys need to exchange for a new phone. My first Lumia 900 had restart issues while idling. The new one doesn't have any reboot problem. My G2X before had reboot problem and screen bleed. I went and exchanged for a new G2X, and problem solved. I will send my Lumia 900 to Nokia for repair as I have another hardware issue. The capacitive buttons aren't very responsive when playing audio through speaker phone.

[Q] Random rebooting and wifi calling dropped calls

Hi,
Anyone know how to fix random rebooting on the SGN3? I have to remove the MicroSD just to get the system to stop then I re-insert it and everything works fine again. This happens maybe every one to 3 days. Phone gets warm fast as well but after it reboots everything is golden.
Also when on wifi calling I get warnings that my connection could be dropped and once it did. The phone says my wifi is unstable but my mac and SGN8 don't have that issue and stay connected. Is these issues that a future update can fix or is this model defective and I need a replacement?
Thanks in advance.

"No Service", cannot turn on mobile power

I have an XZ2 Compact, running latest build available from Sony (Android 10).
My symptoms are pretty much same as [this post](https://www.reddit.com/r/SonyXperia/comments/a1tym6/cellular_radio_power_will_not_turn_on_x_compact/).
Background
I am changing my phone carrier. In the morning I wake up and noticed that a notification that says, "SIM card not provisioned". So I put in my new SIM card, and then the problem appeared.
The problem
On the phone it says "No Service".
If I try to trigger manual carrier selection, it will return an empty list with error immediately, saying that no carrier is available.
If I try to open testing mode (*#*#4636#*#*) it will report that cellular radio power is off. I can click the button to turn it on but it wouldn't actually do anything. Same with the network selection -- it says "Unknown", I tried to force it to "WCDMA Only", but it wouldn't stick -- it would just revert back to "Unknown" if I open testing mode again.

Hi,
did you manage to fix the problem? I'm facing similar issue (radio mobile power turns off and on, sometimes it stays on but not very often). The problem appeared suddenly about two weeks ago (no prior software update, I'm running Android 10).

It seemed to work momentarily if I drain off the battery completely (remember, there probably are still some residual juice even when power drops to 0%). I just let it sit for weeks before trying to turn it on again. And then it would work. At least for a short while. But as long as I reboot it again, it will have the same problem -- i.e. shows no service, but not prompting that e.g. a SIM card is missing.

Hello, im facing the same issue. I just got xz2 (single-sim model) phone for a few days, working without any issue. But after some time, my phone show ‘no service’ even though i have inserted my simcard in it. I even tried flashing many different firmware but cant find a solution. Anyone got the same problem?

I am having this problem too. XZ2 worked fine for a couple of months then randomly a couple of weeks ago I have no signal.
