BUG : My wp7 phone reboots by itself :(

Now my wp7 phone suddenly reboots by itself
Does anybody face the same issue?

That could be due to overheating. Which device do you own? HTC?

mine kept restarting yesterday. The thing that fixed mine was taking out my SIM card and inserting it again. I think it came loose.

Did you replace the sdcard?

What devices are y'all using?!?!
I have a Focus and it's fine.

I'm using the LG Optimus 7.
I had no problems the first 2 weeks. Now it's becoming more and more frequent.
I heard that some HTC had the same issue. So I guess it's maybe rather OS-related than hardware-related.

Cool. Just saw you're living in Davis Does the Graduate still exist?

I got samsung focus and no problems with reboots. I haven't installed any extra SD cards yet (where the issue is mostly noted)

I have the Focus as well and no reboots here

I have an HD7. My sim card is crazy old, it has caused problems for me before.
This was the first and only time I have had anything weird happen with the HD7. But since it was my sim card's fault, it isn't a big deal.

I have an HD7 also, using the original sim card from the last 3 years and mine phone is working perfectly. No auto-rebooting at all.

got 1 reboot with lg optimus in 1 month.

Well, today i was wondering why my LG restarted itself for no reason.
It seems i'm not alone :-/

Haha, yeah my gf and I keep meaning to stop by there.

I have a Samsung Focus....16 GB SanDisk class 2 card installed. Mine is also rebooting itself for no reason and doing so with increasing frequency. Is the consensus that this is a software issue or should I get a replacement device?

i would suggest to remove the microSD card and try using the phone for a few days without a microSD card. see if it's working accordingly without it?

the only thing that sux with that is you lose that sd card I think. Can the phone reformat the card (I know nothing else can yet)?

Do you have weather bug installed? I was having no reboot problems after a weeks use, then I installed Weatherbug and had 2 reboots in 2 days. Uninstalled weather bug 3 days agon and not one reboot since

Only happened once (that I've noticed) - on a HTC Mozart.
I've got Waether bug installed as well (and it was playing up yesterday - seemed to be stuck on 'Tuesday'
Weather bug is OK again this morning, so I'll monitor this.....

worry about getting your phone working first, after this, we'll work on the sd card ok?

Xperia S SIM card issue

Hello. I'm new to this forum and I hope s.o. can help me. I bought xperia S but it seems that it has an issue with the sim card. The phone is not locked to any operator, it works fine most of the time but the problem is that sometimes the phone says SIM card is removed or no sim card, so I have to restart it. Sometimes I have to reboot ~10 times to get it work. When it says sim card is discarded, and I really discard it, it says SIM card removed, restarting.. and vs when sim is plugged while phone is turned on. It seems that the phone itself knows when there's a sim card inside. The sim card is working fine, tried it in another phone, everything went fine. Usually this problem happens when the phone gets hot (while playing games or capturing video, etc..). I don't think it's because of the sim slot but who knows.. Tried phone repairing and updated with latest firmware, but no success. The phone is not rooted. It seems to be a hardware problem, any suggestions?

Sending it for repair may be your final option.

Yes, I know that but it will take about a month to fix it and I am not sure if they can fix it either.. It's a second hand phone, maybe the first owner tried to root it or did something wrong while updating or sth? Because it's not logical to work excellent and undetect the SIM when I start more applications and the phone gets hot. How can I reflash it to stock ROM so if there's anything wrong in the file system to be fixed? Someone here had exactly the same issue but my sim card is brand new, 2 weeks old and working fine in other phones. EEK!

Take it back to the shop you bought it from and ask for a replacement?

I have the same problem. For me it helps, I use only the back button and than it`s ok for me.

Oh! Me too.
I think there have a problem in SIM card. But now i know that all of the people cause this problem. So this may be because of Handset. How can i Repair ??

How did it go?
I have the exact same problem, and seems a lot of people are getting it on new sony phones. I have an xperia S too. Did you found a solution? Thanks,

[Q]Sim card removed. Restarting.

Hello,
Yesterday i got this little beast (c1905) and i have a strange problem that i believe it is hardware related.
When i touch the area of the sim card either with the cover on or off the phone tells "Sim card removed. Restarting." and it is rebooting. The sim card fits well and by observing the area i can't see any fault. It is a little annoying when i use the phone in horizontal mode where sometimes unconsciously i put some pressure in that area.
Is this a known issue or mine is problematic? Anyone faced anything similar?
Any idea how i can solve this?
If i don't find anything that can help me i guess i will have to go back to the store and ask them to fix it or replace it...
Rather than that i really like the phone.
P.S. My sim card is new, i had the normal sim so with the phone i replaced my sim card as well.

I am having the same problem.
i thought because i rooted my device that is why it happened..

yes I'm having the same problem... i don't know why..!!

Phones radio or something is acting up.

Not sure what happened, but I've been using my S4 good. Out of no where it started acting up, freezing on me, etc. It's on latest firmware, 4.4.4 OK3. When i look under about phone, and check "service state", it would randomly say, "in service" then "radio off", "out of service" then go back to "in service". Also had/have a problem (haven't tested it for a good while yet, had old sim in and it gave problems, now using new sim, still did it one time atm.) with the phone saying "sim removed" or etc, like it cant find a sim? (weird part is my old sim works fine with other phones, my phone kept losing sim, sim no found, etc)
Weird, never had it happen, bars would go from 2 to 4-5, then drop to 1-3, or to 0 and go out of service. I did factory reset, but ofc it only went back to OK3 stock, tried to use previous modem that worked for me before problems started happening like NK2 modem, nope...still problems, so I flashed OK3 back for now. If i have good bars, and turn on mobile data, it would go out of service completely until i shut it off, cant use my mobile data. Anyone know what's the problem? Phone right now running with minimal apps installed, if you need more information, just ask. Thank you! in advance.

Used the phone for a day with new sim, still has problems freezing up on calls(screen), says sim removed...device needs to restart, etc. Would Flashing older Firmware to like Nk2 solve this? I havent had problems on older ones, but when i got OTA, used for couple months and having problems now. Service keeps being circle with line thru it, when u try to make a call it would say "cannot connect to network or registered on network", dbm was -113(usually -100-115), and asu was 0, when service cuts off, keeps finding service then loses it all day, finds it, then make few calls, and loses it, keeps searching for it. Would flashing OK3 firmware solve it? Maybe OTA went wrong? Idk...or maybe go back to a stable rom 4.4.2?

Is it possible the sim reader is damaged?

Not sure how it could have been damaged, it was always in a case.(guess i saw a video where a guy said they sometimes go bad on gs4's) Phone already been used for pretty good 1.5-2yrs. Phone freezing up, etc would result in a bad sim reader? Anyway to test that it really is a bad sim reader?(if it did go bad)

Was the sim card used with a sim adapter?
I suggested the possibility of a damaged SIM card reader because of the "sim removed" error message.

The previous sim that was origionally used in GS4, was used with sim adapter in an older phone that needed a standard sim, so this micro sim was was in adapter in an older phone, worked perfectly fine on Gs4(no sim adapter, just the micro sim), i even got a new sim card off ebay and changed over my number to new sim, and still phone is freezing up on calls, using it normally now, the signal would find the Carrier, then would lose it so many times, then tries to find it, then loses thru out the day, it's annoying as hell. Never had the problem of losing signal, having out of service sign(circle with line thru it), had good service everywhere till now. I even did a factory reset, started up phone up new, still problems with "sim removed" device needs to restart time to time, losing and catching signal a lot, or no service. Anyway to test/find out it really is a bad sim card reader? Just don't want to do 100's of things and it's not it. Phone it used for work ofc. Let me know if i should try anything, before buying a sim card reader, if it really is the problem.

How is the sd card reader? Both readers come as a single unit and they are not too expensive on eBay.

Not really sure, how the sd card reader is...Haven't really used it, as i didnt really need it. I could try and get back to you on that. Yeah, i checked on ebay, they r like 5$ or so, but still the hassle of replacing it, and it's not it. I'll get back to you how sd card works...etc.
Edit: Just tested my brothers Sd card with tons of pictures and videos on it. Put it in my phone, can easily look thru pictures and videos, unmounted couple times, put it in, works fine without any problems. Any ideas?
Also read online about sim error problem, and lots of people are saying it could be a hardware problem, and need to apply pressure to the ribbon of the sd/sim card.
Phone is working fine without the simcard inside, good bars, sometimes it goes low/no bars, or out of service, but still less then it is with a sim inside for some reason.

This is a known issue with the S4. Mine did the exact same thing. I have researched this and tried every fix under the sun, and nothing worked. I even bought a new sim card tray and replaced it. Nothing worked, and I babied this phone. My wife and daughter also have the S4 the same age and theirs are fine. I gave up and bought a new phone. Wish I could give you better news.

So you pretty much saying it's a hardware issue and nothing can be done to solve it? Thought maybe flashing older firmware or something might solve it, perhaps a hiccup in OTA update or the latest patch that could've caused it. Kinda sad to just throw it away when it was working soo good.... =/

OK, one question? How is the inside of your phone that damaged and beat up? Jeez man, take better care of that thing.

It is sad. And if you google the problem, you'll see a lot of S4 owners were mad that Samsung doesn't acknowledge the issue. I think somewhere on this site you'll find this subject covered in full. Some of the fixes work for a short time, but ultimately it is a hardware problem. Some think it's the NFC chip that is right under the tray (supposedly) that heats things up and causes the malfunction. Whatever it is, it has turned my S4 into a infrared remote for my TV, a Chrome caster for Netflix and Hulu, and an iPod Touch!

Rofl....At least you're still putting it to a good use It was a pretty good phone too rofl. Have you tried everything from putting a piece of foam(ear plug) over the ribbon for the sd/sim that lots of people talked about, etc? I guess if there is no real solution, I'll get get a new phone, prolly an iphone or w.e., had an eye on Gs6 Active cuz of long battery, durable, dust/water proof, etc, Gs6 is nice too but I'm in construction, and it's always in my pocket, need something that can last, and you know, keep a good charge while using everyday use like gps, listening to music, etc. What did you go for after your Gs4 stopped on you?

Yes sir, tried them all!
I like a large screen, The S4 was the first phone I owned that had a screen larger than 4". So, I had to go even larger now. I picked up an Nexus 6 when they dropped the price after the 6P came out. My wife and daughter still have their S4's, so I keep up with the latest here for them.

damn shame... i just dropped to 4.4.4 with the NH7 kernal and modem set... still nada. I had a bit of luck with the separating the right side of the phone trick for a bit, but even that doesnt work anymore... I have a note 3 that im using for a daily driver... but i really find its too large for my taste. The s4 was pretty close to the perfect size for me. Prob gonna scoop up an S6 in a couple weeks. Ill keep it around as desk clock prob and a back up for when i drop and smash the s6 to pieces. I swear the wifi and bt were working till i installed the JDCTeam MM build back in december i think. Which made me think it was software related. Ever since then its been doneski... But tbh at this point, everythings pointing to hw issues...

this $#!T is weird...
I admit defeat...

Well, looks like i kept getting the stupid sim card removed often even with w.e solutions i tried to use. Then out of nowhere my usb port stopped working altogether(cant charge my battery now lol). I give up, don't want to waste money into usb port, then something else falls apart rofl. My other Gs4 also worked for 2.5yrs or so, and died. R.I.P Galaxy S4's lol. Don't think they were built to last.

CM 13 SIM Card Issue

Hi, I installed the 8/20 CM 13 release on my S4 using CWM and it will (about 2-3 times a day) not recognize my sim card and tell me to restart. When it does recognize it, everything works well. To get it to recognize it again, I have to power off, pull the sim, power on, then power off again, and restart with the sim in. I searched and read that changing the modem/radio (modem.bin) drivers will usually fix it. Can someone please point me to the correct drivers and install instructions?

Does the phone do the same thing when running the latest stock ROM? If it does, there could be a problem with the sim card reader.

No, it doesn't. I thought it was the reader first and replaced it anyway.

This tells me it's a software perform. The phone is running the latest bootloader and modem?

No. That's what I need to know how to update. I loaded CM 13 and that's it. I didn't change the bootloader or modem. Honestly I don't know what a bootloader is.
I have baseband version M919UVUFOK3

If you flashed the latest stock ROM from sammobile.com, the phone would have the latest bootloader and modem installed.
A bootloader is similar to the BIOS of a desktop or laptop computer.

So was i supposed to flash the latest stock rom before installing a custom ROM?

I suggested flashing the latest stock ROM because that is the easiest way to ensure the phone's modem and bootloader are up to date and should be done just before you start flashing custom ROMs. It doesn't have to be done every time you want to flash a custom ROM.

Same here..

Apparently this is a common hardware issue with S4, something to do with the battery fluctuating voltage to the sim card reader, I recently found out from a repair shop, whose only solution was to downgrade to stock. Heck no, I got Nouget and ain't turning back! Mine doesn't ever have an issue while it is charging. I flashed over a dozen different roms, tried using a few different modems (even stock), read somewhere that you can press a thin cardboard against the back of the sim card against the holder, that didn't work, tried to blow air into the holder, didn't work either, used different bootloaders, nope, preyed to god that I would not miss a call while I slept, nada, don't rely on wake up calls! Tried a new battery, that might have worked for abt a week.. but the dreaded "SIm card removed" message returned!! So I had some drinks and it got some too.. and I watched it get thrown at me and skip off a table, felt it burn up in the summers, in my pocket on many occasions, this phone has been through many adventures in the past couple years and still works great, never even cracked the screen! < knock on wood > This phone can take a beating, compared to many other phones I've had. Other than the fact the reception isn't amazing, I really love my S4 model 919, its fast, compact enough, great display, good bat life, but like every phone it has it flaws. I'm sure that they wouldn't purposely f with their phones so once its modded it gives you an annoying random bug that would make you want to buy a newer S.
The question is how long you can endure the pain of rebooting every few hours, so why not upgrade??
Samsung want you to UPGRADE TO NEW IMPROVED S5,S6,S7,S80..!!
UPGRADE OR NEVER LEAVE AC OUTLET!!! hahaha
.. Personally, I probably will buy a S7 soon as it drops price ( I have a really active life) but for now I just deal with it.
>>> I'm more worried about when someone is gonna fix the video camera for Nouget !! Big up to ResurrectionRemix and XDA!! <<<
ps.. I don't ever remove the sim card, just a full reboot is all mine needs. GL

Same issue here..
Just a thing I observe. When my sim card shows is disconnected or sometimes after reboot is even showing that my sim card is not inserted, I cannot turn on my mobile data and the sim card app is missing from app drawer and from application manager.
I really don't know if its a software or hardware issue.
Sometimes I get this error randomly, even when my phone is standing still on a table and I don't use it.

Thanks for the replies. So, I got a new SIM card and it seems to be working much better than before. My old SIM had a huge scratch on it, so I suspect part of the issue might have been that. I've also kept it in balanced power mode, and I noticed it happens more in battery saving mode. I've also been trying to keep it plugged in as much as possible, and I have extra charged batteries I swap in. It will also start working after a reboot and I don't have to pull the battery and card like I described before. I still haven't tried to change the boot loader or modem.
Edit: I'm also having an issue with not being able to download MMS unless I'm on WiFi

Are the apn settings correctly entered?

This is a known issue (not CM related); contact your carrier for a replacement.

Just an update: I'm still having this issue, but have just been living with it and trying to keep the phone charged. It seems to happen less on WiFi and when I'm actively using cellular data. Some apps seem to make it worse. I'm probably going to try a different release.
