Possible cause of reboots / hard locks? - T-Mobile LG G2x

I could be off on this one, but I'm curious if anyone else has had a similar experience to mine.
My phone locks up or restarts multiple times a day. I figured it was a hardware issue, and I've already got a replacement on the way. However, I noticed that when I removed my 32GB sdcard and placed it back in my old phone, that the G2X stopped freezing and rebooting. I placed the 32GB card back in, and the rebooting resumed.
I'm curious if there's a chance that the G2X doesn't play nice with certain brands/sizes/speeds of sdcards. Has anyone else noticed this same trend?
I'm using a Sandisk 32GB C2 card. Works great on my MT4G (still), worked great on my Epic 4G & Droid 2. Card tests out fine, so I'm curious if this may be the "source" of the bug some users are experiencing. 32GB cards causing an issue? Slower cards? Anyone have any thoughts on this?

My phone has no SD card, and I have had a few freezes and 1 reboot since I got it on 4/20.

I can't put my phone on charger without having to pull the battery to get it to turn back on.

I noticed almost everytime I accessed my 32gb sdcard that 1/2 the time it locked up.... it seems to scan the card way more than was done with my N1. Anyway...I had antivirus installed. Y the one by avg. So I uninstalled it and since I had lookout on my phone Amway...I enabledits antivirus. And it cut down. severly on freezes.
The other thing I noticed is only do your overnight charging with the LG charger that came with your G2x. Or any long term charging I think.
Also... I know this sucks...but if I turn off my phone and turn it back off every morning I do not get reboots or wake up to a dead phone. I saw this mentioned in another thread somewhere and it seems to work. After I hit about 24-48 hours of uptimei get issues.
Well I hope some of this helps.

Having SERIOUS Issues

Last night, while I was reading a text message, my phone rebooted itself. When it came back on, it told me that my memory card was invalid and that I would need to reformat my phone. It gave me two options: Emergency Call and Reboot. I pressed Reboot, and it turned back on normally.
Everything was fine until it rebooted itself yet again. This time, when it came back, none of my apps/games/anything work. The phone is on, but I can't do anything with it. The only apps that open are 3rd party apps that I sideloaded.
I tried connecting to Zune to roll back to a restore point, but all I get is connection errors. I even tried going into my Settings>about>reset your phone. This told me it would reset my phone back to factory settings. After doing this and having it reboot, my phone is still the same. All the apps are still there and not working, and even my custom theme is still there.
Someone please help me.
AT&T Samsung Focus
I just did the hard reset by holding Power+Camera+Volume. It seems to have worked.
Any idea what could have caused this? I mean yeah I did a lot of registry tweaks, probably making it somewhat unstable, but this isn't cool...now I have to re-unlock it, re-force NoDo to install, etc...
EDIT: Well, the factory reset is still...resetting. It's just sitting on the Samsung splash screen not doing anything. I'll report back if it never leaves this screen.
im guessing you are usig a samsung focus? if you are you would have better luck posting is the focus forum but it sounds like you are using or you used an incompatible sd card with it.
check this thread out http://forum.xda-developers.com/showthread.php?t=834144
and im personally using a samsung 16gig sd card bought from ebay seller nikolai1778(or something like that) since december and i havent had any issue so that card is certified. hope that helps
Yes, I am using a Focus, but I have had this card in my device for months and months. It has never given me any issues.
I took the card out, factory reset it again, and it is giving me the same "Storage card not working" message. The card isn't even in my phone anymore.

what size is the sdcard? you probably just now recently used up all the space on the card and thats when you started getting the random reboot and data loss. read the thread i pointed out to you a lot of the issues you are having are documented there and the only known fix is to get a certified sd card or take out that sd card and hard reset the phone.
Again, I took the card out, hard reset it, and it's just stuck on the Samsung screen.
It's an 8 GB Sandisk Class 4

im out of ideas here, thats the 1st time i have heard of that hopefully someone else can help u out. you can try calling or taking your phone to at&t
Yeah, I still have my warranty (I think?). I left it sitting on the Samsung boot screen for about half an hour and it wouldn't budge. Seems to be bricked, although if I just try to turn the phone on normally, it shows the storage card error (without the storage card present). It gets stuck while reformatting.
if you can go to settings/about/reset your phone do it whitout your sd and again with your sd card

I don't think that is the problem. From what rmcgraw has described, it sounds like the phone is bricked, with or without the card installed. I don't think this is something that is a user-serviceable problem. My guess is that the phone needs to be replaced.
Yeah, I can't even get into the phone to go to the settings. As I had said, I tried hard resetting from the settings menu twice, to no avail. I have no idea why this happened, it was completely out of the blue. Hadn't changed any registry values that day or installed any new apps. At the time it happened, I had my phone plugged into my PC to charge and I was reading a text message.
I'm leaving for the AT&T store right now, I'll let you know how it goes.
Well, after about an hour of standing in the AT&T store on the phone with the warranty department (they couldn't even do anything in the store to help me), they told me they had no idea what was wrong and that they'd send me a replacement. I have to send my original phone back to them obviously, and if they determine that it's my fault, I have to pay $410. Oh yeah, and I have to wait a week for my phone.
I am having the same problem with my surround. Got my first one warrantied out because it was bricked at the HTC splash screen after getting the memory card error. Now my second surround is giving the error every couple of days and has needed a hard reset for the same reason you mentioned. I haven't done anything to my phone. No jailbreaking or whatever. And both have the original sd cards.

Maybe your computer over volted in some way and the memory card ( not the removable one, the internal one) got damaged. I know that when I plug my Samsung focus into an Apple usbwall adapter that the touchscreen doesn't work (capacitive buttons do tho?) and it may reboot its self. I assume this happens because the Apple charger releases an incorrect voltage to the phone- ie; more or less than the phone needs and it causes the device to stop working properly. Never had any lasting effects on my phone, but I just can't use an Apple USB adapter

UPDATE
Received my new Focus on Monday. Everything was fine until a couple of days ago. Just so you know, I did NOT re-install my 8 GB Sandisk Class 4 microSD, and I did NOT unlock my new device. Everything is stock on it, except for the apps I've installed.
Now back to the issues: It started crashing randomly a couple of days ago. It would do it when I plugged my phone in, as I entered apps, and sometimes just completely out of the blue. Yesterday, I got the "Storage card isn't working" error, even though a storage card has NEVER been in this device. That error actually froze, the phone re-booted itself, and has been working normally since. This is how the my other Focus was acting before it bricked.
So, my question: Is it the battery or my SIM card (those were taken from the other device)?

If i had to guess is the battery .....
This may be completely unrelated, but I found it interesting...
I had installed the "Drive On" GPS app on my old device. I didn't like it so I never used it. I had made a list of all of my installed apps right before my phone bricked to reference for when I got a new one. When I got my new Focus, I did not install Drive On.
After I started having problems with my new device, I noticed that Drive On had appeared in my app list without me installing it. However, it wouldn't open. I uninstalled it and my phone hasn't crashed since. I haven't gotten the storage card error since then, either. In fact, my phone has been running flawlessly and maybe even better than before.
I could be crazy, but Drive On seemed to be a rogue, phone bricking app that I will never install again.
Phone was acting up again last night.
5-7 crashes/reboots, and I got the "Storage card not working" message again.
It's strange how these problems seems to come in waves. The phone will work perfectly for days straight, then will go crazy and have tons of reboots and errors within half an hour, and then will go back to working perfectly fine for a while.
I want this to stop.
Ugh, it just restarted itself and is now showing the "Let's get started" screen, as if it formatted itself. I took the battery out and I'll try to boot it back up in a few...
Why am I having such bad luck with these phones?
EDIT: Yep, the memory is completely wiped and everything is back to stock. All I did was plug my phone in because the battery was about to die. Every single one of these problems has occurred while the battery was extremely low and the icon would stay at the top of the screen reminding me to charge it. As soon as I plug it in while on low battery, the problems begin.

A day after re-formatting itself, my phone suddenly fully re-installed (by itself) Drive On again. It opens and runs. I uninstalled it again. It is the only app that keeps reappearing after I have issues with my phone.

[Q] Problems registering with network [SOLVED]

I have been having problems with my phone recently. I was previously running stock 2.1 rooted on Wind mobile. It had been working fine since I bought it in Dec 2010.
I seem to recall leaving my phone unplugged for a short amount of time (like a couple hours) and then when I picked it up the battery had been completely drained (while idle). I plugged it in and started it up after a bit and the battery was suddenly running super hot, and it would reboot quickly after starting. The only time it stayed on long enough to check the temperature I saw 57c. I left it to charge and came back and the battery temperature seemed to be normal again.
However now since then I have been having a lot of trouble registering to the Wind network. Half the time it is showing as roaming, or cannot connect at all. Sometimes, like as I am typing this, it will show that I am connected to the home zone. I can make calls now, but I cannot receive any. I have flashed the phone to CM7.2, and initially the phone worked but the next day it started having the registration problem again.
I tried the SIM card on another phone and it worked. Anyone have any suggestions?
Or you got fryed your phone module.. or fryed sim card.
First of all i'll recommend to replace or try another sim.
Just a little update...
It seems to have been working better in the past week, I could connect properly 90% of the time, but couldn't sent any text messages.
I went to replace my SIM card at the store, they gave me a new one and now it seems to be working 100% fine. So I guess the sim card was the problem.
Something to note is that the sim card was the original one I got when I signed up, and my permanent normal number wasn't on the card, only the temporary one assigned to me for the first day. So that may have been causing the problems I started having.

[Q] strange Charging issues only on WeUI/icy glitch

I recently moved to WeUI and have found a strange problem.
my phone will charge when powered off but if it is on it usually will not take charge.
it wont use battery when plugged in but it wont charge either.
at first it seemed to be only when lower than 30 percent but today i plugged it in at 61 percent and three hours later it was at 59 percent. i turned it off for twenty minutes and powered it up at 73 percent and it kept charging. very weird. today i tried going all the way to stock and back to WeUI again but same problem going on.
worked fine on stock and a couple other ICS roms ive tried today but as soon as i go back to WeUI... very annoying.
I have two stock batterys and one extended life 3500mah battery and same thing happens regardless of which battery is in the phone.
also when on WeUI my phone gets very hot. its not the icy glitch kernel because ive been using glitch since version 8 (now 14) with several CM9/ICS based roms which have all been fine.
the hottest part of the phone is the SD card. i dont even have any files on it (its all on the 10 or so gb internal memory) it almost burns your finger when phones been on for a while.
sincerely,
frustrated
--as i mentioned above the sd card was getting hot.
well even with phone off i could put the sd card in and within about 3 seconds it would hot enough to cause a 1st degree burn. after removing the sd card while phone was not charging it miraculously started charging. no idea why. at least phone works good now. also bat life is almost double than before. it must be shorting out is all i can figure. i dont have another sd card to try at the moment but will update when i do.
If nothing is on the SD card, just try taking it out. Then see what is going on. It is odd that that is only happening on one ROM though.

restarts and SD card drop issues

good morning!!
I have the Sensation 4G with a 32 gig Sandisk micro SD card running Revelation Rom (updated to latest version) that has started giving me a significant amount of problems with restarts. I also have a relatively new Anker battery that has easily doubled/tripled the usable time of the phone, and i don't think it is causing the problem.
The problem first started off when i would press the power button and it wouldn't instantly wake up the display. it would take a few seconds then the display would wake up. Restarts would sometimes help with that, but it never really went away. Then it would all of a sudden start dropping my SD card, often in the middle of an app running which would lock it up and it would either restart on its own, or i would have to pull the battery to do so. each time it restarts on its own, it will not mount the SD card. i have to restart it multiple times to get it to mount.
I don't think its the ROM b/c I have been running it for months without issue. The only other software change that was recent was my SU binary was out of date and i updated that. It really feels like a hardware issue to me. like the back of the case is grounding out somehow or it could just be that the phone is 3 years old and at the end of its life. Has anyone else experienced issues like this?
I am unlocked, but with S-ON. i am using the most recent stable version of 4EXT as well
Thanks!

Excessive overheating causing phone to shutdown

Hi all. I'm really hoping that you all can help me out here. I have an At&t LG G3 D850 and I had to replace the SIM/SD card reader on my phone because pins for the SD card reader were bent and would not recognize my SD card, but it recognized my SIM card just fine and I was able to use my phone. I took my phone to a repair shop and they ordered a replacement SIM/SD card reader and replaced it for me on my phone. After they replaced it, my phone began to overheat to the point where I would receive a popup on my phone stating, "High temperature detected. Device will be turned off for your safety if the temperature rises higher. Please use after a while." and then about 30 seconds later, the phone shuts itself off. I've tried a second OEM battery that I have as a backup, I've tried doing a Factory Reset, I've even tried flashing back to stock firmware, but this continues to happen. I installed CPU-Z and found that the temperature of my phone was running at about 127° F. I let my phone cool down over night, with no battery installed and now when I put the battery in and turn the phone on, it boots up and then shuts down with no warnings. I've had this phone since it came out and I've never had any issues with my phone, especially no overheating issues, until I took it to have the SIM/SD card reader replaced. Aside from taking the phone back to the repair shop and demanding they fix it, what can I do to fix this? I know that I can find a replacement board on eBay for like $50, but I don't want to put more money into my phone. Thank you all, your assistance is greatly appreciated.
