Z2 Freezes after SIM card change - Xperia Z2 Q&A, Help & Troubleshooting

I don't know if anyone has ever experienced this issue, and it seems rather strange to me. It is the second time my Sony Xperia Z2 dies (just within a week) so I am fairly certain the reason (or the trigger) is when I pull out the SIM card tray without powering down my phone for a SIM card change. As soon as the SIM card tray is pulled out, my phone detects a change or SIM card and it automatically reboot and once the device is restarted, it starts freezing on startup, and the phone is basically unusable.
Last time I had to flash the stock rom over and wiped everything, does anyone know if there are any other way around so I don't have to wipe my phone clean and go through the pain to reset everything again?
Update: It seems that the SD card is the issue instead. After I restart without the SD card, the phone seems to work fine, but most of my apps are moved to SD card, so is there any way I can solve this? Once I plug the SD card back in, the phone freezes almost immediately. I checked my SD card by plugging to my PC and it seems to be error free.

Do you have es file explorer installed?
I had an issue with that my phone would freeze at startup but uninstalling it would fix the issue

Peculiar DAMAGED SD CARD problem.

I've read upon the DAMAGED SD CARD problem with android, but most of the phone becomes virtually unusable, mine says it's damaged but market works, and I can install apps to phone memory, even with APPS2SD enabled. If I try and copy my files to the computer, it stops halfway with 'perimeter incorrect', glad I did a backup like 1 week ago. Funny thing is, in recovery the SD card is fine, I can make backups, I even tried to repair SD Ext Partition, no luck.
Its probably Android thinking it's damaged without it really being so. Totally confused since I warning/error is on the ongoing notification. Also when I go into the SD card & phone storage shows information as unavailable and SD information widgets can't read it either. I don't mind formatting and copying everything over, but it kinda works, but android thinks it's corrupted or something. Very weird. Also I did nothing out of the ordinary, but with computers or machines random errors can occur. I had the partition in place for a 3 weeks now, installed MCR 3.1 couple of weeks ago and using it pretty much like this, but since the WIFI hanged (kept saying it's turning off but being stuck) I rebooted and the message came up.
Is it possible to fix it how it is? Or shall I just re-format and copy everything again. I'm just worried it may happen again.

LG P500 reboots and sd card

Hello,
I'm a new owner of a phone with android, since a month ago. The problem with my phone is that some time ago it started rebooting about 2 times per day (in some cases rebooting even I'm not touching it)
I tried removing almost all applications and didn't work (the first app was task killer since I read that's not needed).
One thing that may be helping the phone rebooting itself is that some times I see this notification: "SD card removed unexpectedly".
I have a 8gb class 2 card. But I tried with a 4gb class 4 card and same message appear. I tried formating both cards and didn't work.
Anyone can please help?
Best regards,
Pedro
and my P500 do a restart the card SD (2GB, which was from the market) and probably due to the firmware of the LG (it has a .10 b) so I expect the update from LG that fixes the problem

thousands of us are facing this problem. LG are idiots to have released the phone with such a glaring defect.
But also thousands of us doesn't have any problems with this. It's really strange and you can not say, that LG is idiots - maybe everything works before on testing. Maybe some factory failed in collecting, maybe some wrong series of components... maybe.... who knows.
One think is true - they should face up to problems and not do, that nothing happened.
So the only thing that I can do, is wait for an software update from LG? (perhaps android 2.3 resolve it?)

I doubt whether this is related to software, since other phones don't face this issue. The phone has crashed several times at the end of a call, and I couldn't even press the disconnect button. When the phone doesn't even be stable and do the basic phone features properly, nothing else matters.
I also had this problem.
SanDisk 8GB cl2: reboot 2-3 times daily. Best 1% / hour battery.
SanDisk 2GB cl2: remount frequently. 1% / hour battery.
Original card that came 2GB(Samsung?):NO reboot,NO remount, 2% / 8 hours (night) battery!!!
My sd card didn't remove but the device some times start a reboot, and after a few seconds it enter on the phone (after the text ANDROID when i can see the desktop), when the phone signs he's mounting the sd, the phone goes on reset again and do this for several times, and i can't acess to the device. Some times he works normally.
I tryied to start the device without the sd but when he resets he still reset even without sd, so i don't think this isn't a sd question.
Some one else have this problem?
I update to the v10b by lg suite yesterday. I dont have the random reboot problem anymore for the last 24 hr. and I play pocket legend and like ever 2 hours the phone must reboot with the v10a. Now I am very happy with the v10b. no reboot for the game playing but i felt the graphic is little bit slower than v10a. and I am also factory reset my phone after update. So I can tell is it because the firmware or some software on the card or the root causing the reboot. But I am sure I am a happy pocket legends player. I am also using my old nokia 8g class 4 sd card with the original sd back up.
After I update to v10n, I've been runing android whitout rebooting and unmounting for about 125 hours (and growing).
I can say the software solved the problem because im using same card and I didn't factory either the phone or card.
My software version is already v10b by default but I'm still experiencing this "sd card removed" problem plus my phone also reboots it self rarely...
I've read threads about this problem and they recommend updating the software to v10e...
I contacted LG about this: It seems that the reboot bug is SIM-card related. Here in germany, Eplus (and their retailers) SIM-cards seem to be affected.
hi after updating to 2.2.1 v10n i dont have sd card error and reboots that often but sometimes i cant see the apps installed on the sd card. has anyone noticed this too? after remounting the sd card i can again see the apps and can access them but it keeps on appearing and its quite annoying! plz help!
i have both problems rebooting sd card and disappearing apps
i also have v10n

Based on my experience, I'd say the reboot is triggered by the unexpected sd card removal after moving apps to the sd card. Until I've seen some working prove, I'd assume the idea with SIM-cards is just another theory.

I have the phone from late october and experimented a lot with this problem.
In my case it only happen if I move some apps on the sdcard, if I don't move any apps on the sd card, no reboot happens. Also it seem more frequent when data connection is not "stable".
Some user reported they were able to turn around the problem keeping wifi on all the time, but it is a solution I like
In the last couple of months I used the phone with all the apps on phone memory and never had the problem again...
I got this phone a week ago and it's been rebooting ever since.. I even updated to v10f and now it says something about the SD Card after reboot and the SD card wont work after that.. so I have to reboot manually for the SD card to become active again... this phone is nothing but headache... but I'm still happy with it..
Do custom ROM's also reboot randomly?
you need atleast a class 4 sd card, im using class 4 16 gb sandisk. Absolutely no problems at all.

[Q] Unusual Notification appearing

I had this strange notification appear after I removed a couple of system apps with ROM Toolbox (Thinkfree and Yahoo Finance). When I tap it, nothing happens.
I tried to clear cache and it disappeared for a while, but only to return.
Does anyone know what it means? How to get it to go away would be cool to.
My phone has GR2.0 running.
Try removing your SD card and then boot.
Looks like the phone is not able to read you sd card.
Definitely.. I think it's a SD card problem.. The logo says though..

The phone is definitely reading the SD card, it can access the files and my apps load at start up.
I attempted a couple things. I turned the phone off, took out the SD Card and started it up again, initially the notification wasn't there while it was doing the SD card scan, then it re-appeared again after a duration.
Then I tried doing a factory reset as well as clear cache, this had the same outcome. My next step would be to reinstall the firmware.
Could it mean the SD card is damaged in some way?

External SD Card No Longer Recognized

So basically what happened is I rebooted my phone, and then opened up my music app, and it said that my external SD card folder (where I keep all my music) was missing or unreadable. I checked my file explorer to see what was going on, and I opened up the external SD folder to find that it was empty. I know for a fact that all my files are there, since everything was working fine until I rebooted my phone. This happened once before, and I solved it by plugging the card into my computer and formatting it from there. I could do that again but is there a way to fix the problem altogether? It's annoying to have to format the card every time I reboot my phone.
My phone's not rooted or anything. 100% stock.
Thanks
Use RECUVA to recover any files back up data and factory reset format phone FAT 32 in Windows .

Okay, I'll try that. Thanks
I factory reset my phone this afternoon and for some reason it's still not detecting my card. I tried the card with my brother's S3 and it worked perfectly fine. Is there anyway else that I might be able to fix it??
EDIT: Never mind, I somehow managed to fix it

[Q] Weirdest SD Card Problem - Refuses to mount until inserted into PC

Hi,
I have Galaxy S3 running CM10.1 Siyah Kernel (problem has occured over several months of various CM10.1 nightlies) and I just cannot figure out why the following is happening. Please read the thread carefully because I've ensured that every sentence contains details which should be important clues to the root of the problem.
Sometimes following reboot, the phone completely refuses to read my memory card. In this state, the phone does not give me the Unmount option, but when I remove the memory card directly then it does show the 'Removed SD card in the' notification. Now if I insert it again, it shows 'Preparing SD card' in the notification and this notification doesnt go away by itself (which it should if the mount is successful) and the card does not mount. This situation does not change no matter how many times I repeat the process. After several attempts, I get the ongoing 'Damaged SD Card' notification. Dozens of reboots dont help either.
After loads of trial-and-error's, I have concluded that almost everytime that this issue has occurred was when the memory card was in-use (playing songs etc. Accessing anything off the memory card basically), although on rare occasions it has also occurred when no apps were in use at all. This gets me to believe that the software is failing to properly release some kind of lock on the memory card before rebooting.
Now the only way to get the memory card working again on the cellphone is to put it in my laptop memory card reader, and it can instantly read the memory card. Now if I safely remove the memory card from my laptop and insert it in the S3, then it always mounts on the first go. Now it will work perfectly again, until some completely random time (usually at least 1 week away) when it will start its problem again.
Also note that whenever this problem occurs, Developer Options does not load and crashes.
I want to reiterate that this is not repeatable each time. Even if the conditions are exactly the same (well, as far as I can see as an end user anyway), the problem will very likely just occur in just 1 out of the 50 attempts.
I have already got the memorycard+sim card slot replaced from samsung under warranty. I have also paid extra to buy the SanDisk memory card from SanDisk themselves based in the Czech Republic - so it is extremely unlikely that it is hardware fault.
Can anyone shed some light on this situation? Feel free to ask for any clarifications, I have tried to put as much information as possible.
Thanks
Make a nandroid, flash a stock rom and test again. Format the card using sd formatting tool first.
If that cures it then ask your kernel or rom chef for help.
