HELP XDA! Phone Reboot's if using 3g Data

Hey,
My AT&T rooted nexus one is still randomly rebooting if I use 3g data. I am in Costa Rica and the 3g is on the 850 band. I also have to add the apn "kolbi3g".
So basically I can use the phone for anything and it works great, but if I add the apn and start using the 3g heavily I will get a reboot, sometimes it will reboot vibrate 7 times and I have to pull the battery. I have tried 2.1 and 2.2 rooted and not also cyanogen 6 all the same problem.
If I do *#*#4636#*#* and select the wcdma only it runs the 3g better but reboots way more, sometimes the instant I place load on the connection. However if I select wcdma "unkown" the 3g works much better I can use it sometimes 30min at a time without a problem.
So any ideas what I could try? Is there a kernel that will up the volt's a bit just help stability? Or anything else I could try? Data roaming is off, I have tried both off and on, no difference that I can tell.
Thanks a lot this is driving me crazy! Just got this phone Sunday too sick to my stomach of the thought I spend $600 on this phone if I can't get 3g to work

How about radio image???
It is currently on baseband 4.06.00.12_7. Is there a more current radio?

I came across this multiple reboot issue on a (locked) Vodafone UK Nexus.
It booted into the OS (lockscreen) and as soon as data connected it looped back to the last couple seconds of the animated Nexus logo.... and again.... and again.
I powered down the unit (battery pull), booted into bootloader (voldown+power) and selected clear storage (voldown,voldown,power) then (volup) to confirm.
This deletes the user data and you have to sign in and set up the phone again but it certainly fixed the issue. My only guess is some user data became corrupt and the kernel panicked and forced a partial reboot.
Give it a try and lemme know.

Just did that (had the phone plugged into wall charger), and the second I got to the home screen it rebooted then vibrated like 6 or seven times. Seems to do it worse when it is plugged in. And now it won't even boot up even after pulling the battery, it vibrates 6-7 times.
I am really worried about this, any other ideas??? I will try anything! Thanks for the help

Update! Now the phone just reboot when I do anything period with it plugged in. Just like posted in another thread on this section!
Please any ideas I am very desperate and very sick to my stomach!

Hmmm very strange.
I'm aware from what you were saying on the other thread that you've got an unlocked bootloader and you're wondering what to do on the warranty front.
If you've really tried different combinations of stock and custom firmware and having the same issue I'm tempted to say its a hardware issue.
Many people have returned their unlocked phones with no comeback from HTC some have reported that they have noticed the unlocked bootloader and have issued a motherboard repair as part of the fix because of this.
Although im unsure of the additional cost (if any) i would definitely recommend going through the warranty repair route with HTC. They won't say no and send you back the same broken phone. And who knows, if its a confirmed hardware issue they may just replace it as a goodwill gesture.

Other than that I don't have any more ideas.
A nexus support thread has a popular answer referring to the clear storage fix.

Just make sure you are definitely clearing the storage FROM THE BOOTLOADER before calling HTC. It is the first thing they will make you do before accepting a return anyway.

Ok thank you so much sir. I am so glad to hear that I may still have a chance at getting it replaced! It was very fullish of me to unlock it, I know, it is just that I figured it was software and could be fixed by unlocking. It is going to cost me $$$ to get this to the States, but that is life. If I still can't get it to work I will call htc and let you know what they say

Little update here. I cleared storage again and just simply disabled data, I have been using the phone for a couple of hours on work without any problems. Next thong I am going yo yty is another friends 3g similar card and see if it still reboots on that sim, if it does then I am calling HTC.
Also still open to any other ideas you guys may have.

[Q] HTC One Screen Problem

Hey guys,
I bought an HTC One about 15 days ago. Within 2-3 days of using it, I started getting problems with the display screen. I suppose this problem was seen by few people who owned the HTC One X but I couldnt find any useful solutions in those formums hence im posting here.
This is what happens:
1. Whenever I receive a call, the screen goes black and doesnot turn on until I hang up the call. This effectively makes the device useless as a phone, as I can't see who is calling and also during call I cannot access the screen.
2. Sometimes, there is a delay with the power button. When I press the power button, the touchscreen becomes responsive but the display doesn't turn on.
The problem is, if I factory reset the device, it starts working perfectly again!! Again after about 2 days it starts the same problems.
So I thought it was a software issue and so, I got s-off and installed the GPE Rom on the device. 7 days passed, no problems. On the 8th day, the same problem occured again. And as earlier, factory resetting solved the problem.
Is this a software issue, hardware issue or something else I dont know about?
I have taken a video of the device malfunctioning, but I don't know if I can post it as an attachment.
Thanks in advance!

upload it on youtube and post the link.
And something else. Make a factory reset again and then don't install any apps. Does the error also occure?

Im new to XDA forums and hence the site does not allow me to post URLS. However I have uploaded the video to youtube.
If you put 'HTC One screen problem Aniruddha Joshi ' in the youtube search box, you will find my video.
Im sorry I couldnt think of any other way
I did not install anything out of the ordinary. Just updated the existing google apps and installed facebook, twitter and whatsapp! No crazy apks or unknown apps.
Also, once I factory reset the phone, it starts working perfectly and there is no way to know the time after which it starts giving problems again. Once it was 3 hours, once it was a week.
So I don't have any way to check if some app is causing the problems.

after seeing your video, I am even more confused. I really don't know what could cause this problem. But the fact, that I didn't have this issue and almost no other person too, makes me think about a hardware defect. But the randomness and that it only occures after several days don't support this theory. So the only thing we can do about his is basic troubleshooting.
- 1) Try to flash Cyanogenmod and try this mod for several days
- 2) Try another Rom, for example: Omni Rom
- 3) Try to use a different Kernel for GPE stock.
- 4) Use a RUU that matches for you
Sorry, I don't have any other ideas left! But after this troubleshooting we may get new information or gain some knowledge that allows us to determine the cause of this error more exactly!

Try flashing a Sense ROM, like ARHD or MaximusHD?

The original device shipped with sense Rom. I flashed GPE to check if it was a software fault. But no luck. It gave the same problem although significantly later(about a week after I flashed it).
One more thing, I hope this gives some more information..
One time, I had rooted the device and installed a custom recovery. The phone was then working perfectly for about 4-5 days. and then later when I went ahead and unrooted the device, it immediately started giving problems. So I rooted it again hoping that the problem will go away, but no luck...the problem persisted. So, I had no option than to factory reset again, at which point it started working perfectly again.
This is all so bizarre, I have never seen something like this happen
This is just a theory, but is it possible that there is a problem with the hardware which gets triggered only on certain conditions, like some interrupt, or flag or something like that?
So until those conditions are not met, the device runs perfectly, and when they are, it starts giving issues.
Thats all i can think of as the reason.

well its clearly something youre installing if it is occuring after a few days, a root app which controls your sensor or brightness probably, do you have apps of that nature?

No I rooted the device but did not install any root apps...i unrooted the device to install the GPE Rom(not necessary i know, but it seemed like a proper way) and found that it started giving problems immediately. Can non-root regular apps also cause such problems? I had installed only a limited number of apps anyway, updated the pre installed apps, facebook, twitter, whatsapp, some games..thats it..nothing wierd..

Might be a Screen-Off max. frequency issue. Like the phone gets only 500Mhz in sleep mode at maximum. Which is to low for an incoming call. Could you install a app like Android Tuner or Trickster Mod to check your Screen-Off Max frequency. If it`s that low, set it to ~1000Mhz.

That is very stange indeed. As I don't know any other causes for this error than:
Underclocked CPU or/and GPU on screen off
Root application that controls the brightness
Hardware issue(But what would cause this???)
I can only advice you:
Since you are S OFF, take a RUU, and follow this guide and ****ing set back your device back to stock! Don't root it! Don't use custom kernels. Don't install any strange apps that may control your display brightness. SERIOUSLY! Don't install an app that controls brighness even if it works on a friends phone! Just don't!
And if you still get this issue: It is a hardware issue! If you followed step by step the instruction and if you did everything I told you to do, it HAS to be a hardware issue! The fact that the error didn't appear on GPE that fast is caused by the lower performance requierement by GPE! So I seriously have doubt that this issue is caused by a hardware defect. But it isn't impossible for sure. I just have the impression that you changed some system files and you didn't know what you were doing. This is NOT against you, but it seems to be a reasonable possibility because a factory doens't reset the /system partiton.
P.S.
I'd be very kind if you hit the thanks button since we, the community, are really trying to help you.

I will definitely follow your guide and try to troubleshoot the problem. I hope its not some hardware defect and I dont have to send the device to HTC. I've heard those guys are poor at customer service
Thanks a lot, you've been a great help!
Btw, I was trying to find that Thanks button since the first day, I just couldn't figure out where it was. I just did.
Thanks again

Yup try installing kernel and custom rom.
Remove the case and try ( i know this is stupid thing but can give it a try)

[Q] Radio shuts off for ten seconds after every call

I'm running 4.3 rooted on ML2, stock ROM. Within the last week I started experiencing a strange problem - after every single phone call made or received, I lose all network connection for about ten seconds. I get the circle with the line through it. Going into settings shows actual connection drop, not just the icon. Then, the connection reappears. I've made no modifications since rooting it in April, nor do I recall removing or freezing any apps any time recently. Powering down and/or removing the battery has done nothing to help.
Any ideas what would cause this? I can't find any threads here, or through a google search, discussing this problem. Any help is appreciated.
Update - same problems when running in safe mode.

Well, this seems to have been a local network problem, as the issue has magically disappeared. Nothing exciting to report.

Remove SIM card and clean?

Yep - did every trick in the book. Even reflashed via Odin to be sure I didn't have a corrupted radio file. It just started working again. I"ve seen the same problem reported in other parts of the country, apparently the result of something AT&T was doing to the network.

Some issues I've had (2 days in)

Love the device, but this one is going in for an exchange. Not sure if it will resolve the issues I had, but my phone was behaving badly. I unlocked and rooted it about 10 minutes after I got it, using the Chainfire method here..
1) WiFi reception is awesome, except it drops the connection constantly! I have an entry level commercial AP (Unifi) and the thing is awesome. All kinds of devices connected to it, but this Moto can't stay connected. From the logs on the controller, it appears to be switching channels constantly. Wifi goes from all bars to bars with x to off.
2) Reboot results in bootloop. On more than one occasion, I had to reset the device multiple times to get it to boot. This morning, I could not get it to complete a boot at all. I've since reflashed the Tmo stock ROM.
3) Lookout randomly comes back! Froze it with TiBu, stop and disable in app manager... nothing kills it! Reason 1 for root!
The WiFi issue is a killer. Again, I am going to take this one in and exchange it for another and hopefully the WiFi issue is gone. I think I'll need to restrain myself from rooting until I pass the exchange date.

I had similar issues what i did was flash the stock boot img then do a factory reset and reroot and everything is good now

Thanks! I will give that a shot before I take it in.

I've been back on stock with unlocked bootloader for a day and change, and I still get WiFi drops. It seems to happen more with BT on, but they certainly haven't gone away. I've changed a bunch of things on my AP to try and eliminate them too, but it hasn't helped much. I may try disabling the A/C radio (which fixes it for some), but that's hardly an answer. I am starting to think that this is a Nougat or a Qualcomm issue.

Seems like a hardware issue. If it was a software issue then it would affect more than just you. So far you are the only person on various forms I go to having issues.

I actually have this issue with another device too , so I think it's either an Android, AP or a Qualcomm thing. Some have said turning off the A/C/N radio helps, but that's not a "solution."

Question S21ultra camera issue and reboot

I'm having random restarts with the s21 ultra, seems the phone is having an error in the background and restarts to avoid freezing or something.
I checked all the auto-restart options are off. The restarts really happen randomly, sometimes im watching a youtube video, sometimes chatting on whatsapp, and it happens almost once/twice a week.
But what i noticed lately, mostly its when an app is using the camera. Sometimes i try to launch the stock camera app and it doesn't launch (writes a quick note that its unable or something) and the phone reboots.
Any solution of what to do? I keep entering the members app after the phone restarted and send the crash log to Samsung but until now I have the same problem and no fix.
Its really unacceptable, i have paid alot for this phone, i got the 512GB with 16GB ram and in the end the phone crashes when opening the stock camera app. Really will never buy Samsung ever again

First, you need to track down the source of the problem.
I wouldn't even let WhatsApp run on my phone... it's nothing but trouble.
Try clearing the system cache.
Clear cam data.
Because it's rebooting you can't see what was running/cache last.
This is abnormal behavior and may indicate malware.
Look at 3rd party apps you have installed for starters.

Where can he go to see what apps caused the crash -- isn't there something in the Android system that allows him to see that?

Do a return/RMA before time runs out? It could be a hardware issue.

If it hadn't rebooted it would show as a running or cache app in Device Care or Developer options.
After reboot that's all cleared pretty sure the cache is too but you can double check.

I would try to get the device replaced by Samsung as soon as possible if I had the option rather than trying to troubleshoot it. This is abnormal behaviour, maybe software, maybe hardware but if I can get the device replaced, I'd choose that as the first option.
I had a similar issue with my brand new HTC Desire S (ages ago) and foolishly tried to solve the problem by trying software hacks, almost tripped the security flag and missed the DOA claim window trying to sort it out myself. Fortunately came to my senses and took it to the service centre and got a replacement on the same day.
If that's not an option for you, then we can all huddle together here and try to figure this out.
And by the way, don't hate on Samsung because your device isn't performing well. Sometimes this happens with complex electronic devices. That's what the warranty is for. If they don't honour the warranty, then we can all swear at them with abandon. Calm down and contact the service centre.

Be mad at Samsung for many things. Not this. Their QA isn't that bad and also head-to-head with Apple's, statistically speaking. Wait till you see what Pixels have been doing, LOL.

And by the way, don't hate on Samsung because your device isn't performing well. Sometimes this happens with complex electronic devices. That's what the warranty is for. If they don't honour the warranty, then we can all swear at them with abandon. Calm down and contact the service centre.

It may be hardware or firmware. Or completely self inflicted.
If you can return it, I would do so.
When buying an Android always go for one with an SD card slot; use it as the data drive and the OS/apps go on the internal memory. Makes life and reloads much easier... and faster.
I always build my computers with data drives, even did it with my laptop. Among other things it helps to protect your data. In almost all OS crash and burns, the data drives remain intact. Nonetheless you back up the data drives to at least 2 hdds that are physically and electronically isolated from each other.

I would try to get the device replaced by Samsung as soon as possible if I had the option rather than trying to troubleshoot it. This is abnormal behaviour, maybe software, maybe hardware but if I can get the device replaced, I'd choose that as the first option.
I had a similar issue with my brand new HTC Desire S (ages ago) and foolishly tried to solve the problem by trying software hacks, almost tripped the security flag and missed the DOA claim window trying to sort it out myself. Fortunately came to my senses and took it to the service centre and got a replacement on the same day.

I am not really sure what their warranty policy in KSA is. Will go to them in person and check what they will offer after making a backup of my data. But I expect they do not allow to get replacement (i have the device since about 4 months now) but this problem was not happening the first 2-3 months. But i haven't installed a single new application (so we cant say it may be a new 3rd party app)

Instead *****in you need to track it down...
I wouldn't even let WhatsApp run on my phone... it's nothing but trouble.
Try clearing the system cache.
Clear cam data.
Because it's rebooting you can't see what was running/cache last.
This is abnormal behavior and may indicate malware.
Look at 3rd party apps you have installed for starters.

I do not have many 3rd party apps for starters (less than 20) and i have the same exact apps on my other honor 10 phone which dont have this problem at all, so i believe its not from a 3rd party app.
Clearing cache and cam data are the first things ive done, and the same issue reoccurs.
Im posting this not for *****in but for users to give me ideas of what to do since im frustrated and i have done all the 'quick fixes' i could think of with no success.
If there is a way i can view the crash log, then that might be helpful...

Only way to be certain is to ask them I guess.
Do you get the standard 1 year warranty in KSA? Or is it different?
I don't think there is any harm in asking. if they can diagnose the issue, they may be able to repair it at least, if not give you a replacement.

We get 24 months warranty by samsung here, but I am not sure if they allow replacements in their warranty. I've had previous bad experience where they kept trying to 'repair' the device and same problem came again (long time ago- over 5 years so maybe things have changed).

Wow! That's double the warranty coverage offered to us here in India.
If you think it's a software issue, and don't think Samsung will be of much help, then start with a factory reset. If that doesnt solve it, clean flash fresh firmware. If still no joy, then mostly it's going to be a hardware issue. Whatever you do, don't root or trip the e-fuse in any way if you want to have any hopes of claiming warranty in the future.

Hey
I also had this problem.. My phone would keep restarting while watching any type of video and/or using any app that used the camera. The phone screen would almost become "glitchy" with green lines and restart.
I even had an official Samsung partner come repair my phone at my home. He replaced the motherboard and the battery, but sadly this didn't fix the problem.
Lucky I was still within my 14 days with my phone network to get it replaced.

I'm having random restarts with the s21 ultra, seems the phone is having an error in the background and restarts to avoid freezing or something.
I checked all the auto-restart options are off. The restarts really happen randomly, sometimes im watching a youtube video, sometimes chatting on whatsapp, and it happens almost once/twice a week.
But what i noticed lately, mostly its when an app is using the camera. Sometimes i try to launch the stock camera app and it doesn't launch (writes a quick note that its unable or something) and the phone reboots.
Any solution of what to do? I keep entering the members app after the phone restarted and send the crash log to Samsung but until now I have the same problem and no fix.
Its really unacceptable, i have paid alot for this phone, i got the 512GB with 16GB ram and in the end the phone crashes when opening the stock camera app. Really will never buy Samsung ever again

t's all because the device used is problematic or the application has an error?
