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?
[Optimus One, P500, V General] leonlmf:
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.
[Optimus One, P500, V General] pedroh:
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.
[Optimus One, P500, V General] rubyannF:
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...
[Optimus One, P500, V General] muff99:
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.
[Optimus One, P500, V General] alyy81:
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!
[Optimus One, P500, V General] ciolnadu:
i have both problems rebooting sd card and disappearing apps :(

i also have v10n
[Optimus One, P500, V General] xtho:
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.
[Optimus One, P500, V General] Jimjams:
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...
[Optimus One, P500, V General] ert69:
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.. :D
[Optimus One, P500, V General] sinilill:
Do custom ROM's also reboot randomly?
[Optimus One, P500, V General] ccdreadcc:
you need atleast a class 4 sd card, im using class 4 16 gb sandisk. Absolutely no problems at all.
[Optimus One, P500, V General] chughgopal:
Did u manage to get class 6??

nt available in most shops of mumbai.
[Optimus One, P500, V General] mervbg:
I think its not a card speed problem. I used 4GB Class 2 card and no problems for about a month. Then i bought a 16GB Class 4 card and 2 reboots in 2 weeks.

Its not that big of a problem because it happens when im not using the phone, but its annoying.

LG fix this!
[Optimus One, P500, V General] diordna2:
you can find a list of compatible sd cards for optimus one here:

http://optimusoneblog.blogspot.com/p/carduri-compatibile.html

its in romanian but you should be able to figure out ...
[Optimus One, P500, V General] krige:
I had this problem too. It didn't happen again when using a new 8GB cl6 SD card.
[Optimus One, P500, V General] muff99:
Could you guys please check if the problems persists if you switch on WLAN? Like, keep WLAN activated all the time, even if you use GPRS/UMTS?

I'm in another forum where one of the people observed that the problem vanished if he kept WIFI on all the time. So far, this really seems to help: Instead of switching it off when I leave my place, I just keep it activated and I havent had any reboots since.
[Optimus One, P500, V General] rafaelwmartins:
Same in Brazil

Like many others, I am experiencing the problem with the SD card. :mad:

(I'm in Brazil.)
[Optimus One, P500, V General] XLR8_2K:
O cartão SD que vem de origem é de baixa qualidade.

The original SD card is low quality...and the Android version?
[Optimus One, P500, V General] rafaelwmartins:
I am running the original version (Android 2.2.1, firmware LG-P500h-V10a, which is the latest officially available in Brazil).

What annoys me is the fact of not knowing exactly what causes the problem: software, hardware, quality of sd card, sd card class... LG's support is terrible! According to them, this problem is not recurring, which I doubt! Just look at the huge amount of complaints over the Internet...

Today I'm going to the store where I bought the phone to switch to another.
[Optimus One, P500, V General] nikhil4186:
I don't think they would replace it. my phone was working fine with class 2 card of 4gb transcend but it does not with class 4 card of 8gb san disk.
[Optimus One, P500, V General] Dr.Alani:
Try a higher class SDHC card..like class 6. And get a well known brand..not the ebay garbage cards.
[Optimus One, P500, V General] dislplin01:
I had it when i first got it but after i rooted and put a custom ROM it stopped
[Optimus One, P500, V General] Vivasanti:
I'm using a SDHC 8 gig class 6 - A data, no problems at all
[Optimus One, P500, V General] rafaelwmartins:
I replaced the phone in the store. I also bought another memory card (8gb, class 2). So far no problem apparently, but it is still early to make sure that everything is ok.
[Optimus One, P500, V General] thisab:
I also bought a LG P500 with same firmware (LG-P500h-V10a Brasil) and I have the same problem. I can replace it, but I'm not sure if that would solve the problem.

PS:. I turned the phone off, and removed the SD card and noticed that there are 9 pins :confused:, instead of the regular 8 for microSD's. This strange additional pin is below pin 6 (GND) and between 6 and 5 (CLK), but closer to 6.

Apparently it is designed to touch the pin 6 on the card, but there could be a problem if it touches the Clock signal and its not just a disconnected pin. The 9th pin is for Data signal in a normal SD.
[Optimus One, P500, V General] nikhil4186:
tyre phone reboots on its own accord so I can't make ot reboot in front of the store keeper etc. what did you tell the store keeper?
[Optimus One, P500, V General] rafaelwmartins:
I simply said that the problem occurs suddenly.

NOTE: It appears the problem is really solved. I do not know if the cause was the phone or the memory card, but I think it's just the memory card.
[Optimus One, P500, V General] rafaelwmartins:
It appears the problem is really solved. I do not know if the cause was the phone or the memory card, but I think it's just the memory card. Forget about the pins. If you can, just test with another card with better quality.
[Optimus One, P500, V General] thisab:
Since the day I posted I pushed this pin 9 closer to the 6 and so far I have no problems.

Just for curiosity I moved it a bit to the opposite side. When I tapped on the backside the problem occurred.

I've been reading the reports on Issue 9736 and some people tried different cards to no avail. One solved the problem adding a small paper shim to the card.

I'm not saying this is the cause for every one with the problem, but it is working for me so far.
[Optimus One, P500, V General] rafaelwmartins:
Wow! Interesting...

My phone seems to be perfect now.
[Optimus One, P500, V General] nikhil4186:
can you tell which one is pin 6 and pin 9 and why do we have to do a 69 for the card to work?

did you short them?
[Optimus One, P500, V General] thisab:
If you take a look at the microSD card it has only 8 pins. Now open the SD compartment and take a look at the slot. You will notice it has not 8, but 9 pins. That extra pin is different from the others because its located just below them.

This 'extra' pin seems to be the pin 9 from a regular SD card. But as a microSD doesn't use this pin (in fact pins 8 and 9 are Reserved), so when a card is inserted it's shorted with ground (pin 6).

Looking at the back of the phone, from left to right it's just below the third pin (which is the pin 6). When you put your SD card it shorts both pins (6 and 9).

So what I did was move this pin to the left as much as possible, without shorting them, so when I remove the SD card they won't be shorted. The ones you shouldn't touch follow almost a straight line.

Ps . Sorry that I cant post any link here because I have less than 8 posts. But Google for "microSD pinout" for images. Take a look at where the pin6 on the card touches.
[Optimus One, P500, V General] nikhil4186:
so you mean to say that the extra tiny pin should not make any contact with the sd card contacts. well, we can just use a piece of paper to insulate it from the card, can't we?
[Optimus One, P500, V General] thisab:
I mean that, for some reason, LG decided to short it only when the card is connected. That's why I just moved it to the left.

Edit: But It seems that this slot is in fact a microSD adapter. Since pin 3 and pin 6 on the SD connector side (of the adapter) are connected they could be both ground (pin 6 and 9 in the LG). If this is true you could insulate that pin without a problem.
[Optimus One, P500, V General] nikhil4186:
cool but after updating to v10e my phone has not had this problems.
[Optimus One, P500, V General] IamIrene:
problem solved,which i use back the stock microsd to solve the problem

but the problem for now is,how i format my microsd which i buy and got the restart problem ???

bcoz when i use the microsd that i buy use on phone,it around every 2minute the phone restart itself

so how i format it ?

bcoz i scare when i use it on my phone,it restart again ><
[Optimus One, P500, V General] nikhil4186:
pull down the status bar where you see the download going on. click on the download. It should take you to the market application and to the page where of that app. there you should see the cancel download button.

Alternatively you can go to settings>applications>manage applications>running >Download manager>Force stop. this will force the download to stop. Also kill the market app from task killer or the above method.
[Optimus One, P500, V General] nikhil4186:
You can try to connect the sd card to a pc via another device and delete the .android secure folder.

Or you can just plug in the sd card in the phone, unmount it yourself, then connect it to the computer and erase it.
[Optimus One, P500, V General] IamIrene:
i don't have another device which use microsd

and i got try plug in the microsd which got problem in my phone,and unmount it

but unmount until half,the phone restart again

what should i do T_T
[Optimus One, P500, V General] nikhil4186:
start phone without card (hope the phone does not restart without a card)

go to settings>sd card and mass memory

look for option mount sd card (should be non available since card is not present)

check the option USB mode to mass memory only

With the phone in ON state, plug in the card (stay on the settings page of the phone)

It should mount automatically

once mounted, unmount it!

connect phone to PC via cable

delete the above said folder or format the card.
[Optimus One, P500, V General] IamIrene:
i already follow ur instruction

which tick the usb mass stotage mode,then plug in the microsd which got problem

then it mount and i click unmount

but the phone is restart again,it too fast and i not enuf time to unmount it

what should i do ??
[Optimus One, P500, V General] nikhil4186:
I don't know what else to say. maybe you should try to get a card reader or take it to a friend/shop who can format it.
[Optimus One, P500, V General] Xumit:
Surprisingly, i've never faced these problems.
[Optimus One, P500, V General] nikhil4186:
Lucky you, what SD card are you using with your phone?
[Optimus One, P500, V General] IamIrene:
okay anyway thx for ur explanation :)
[Optimus One, P500, V General] thisab:
After I done the wire thing one week later the phone started the problem again. Damn! I dont know whats going on... It's version 2.2.1.

I tried everything, even other cards of different brands and class. It reboots without any reason and disconnects the card. Only rebooting it makes the SD connect again.

I guess I'll just try to exchange for another phone in the store. This problem renders the phone unusable and no one has a definitive solution. Maybe Samsung Galaxy 551?
[Optimus One, P500, V General] nikhil4186:
There is a definitive solution. Just update your firmware to v2.2.2 v10e. Because this problem has been fixed in this firmware update along with many other bugs.
[Optimus One, P500, V General] mcwong644:
had the same problem after replacing the stock 2gb card to 4gb. changed it again but problem persisted, ie. un-mounting the SD card and rebooting without warning. Then I uninstalled some apps that the vendor downloaded to the phone, I think Apps2SD, Taskkiller, Go Launcher were some of the apps uninstalled . No more reboots or SD card unmounted ever since. So I really suspect some incompatibility issues causing the SD card to disconnect, of course a poor quality SD card would also contribute to the problem. Try to remove those apps and monitor.

Another app uninstalled is Astro file manager. I decided to see if that was the reason. Now I have ES file explorer, Adao, Explorer, and AndroZip installed and no reboots occurred
[Optimus One, P500, V General] gusmao100:
In my case it only restarts if I move apps to sdcard, if I pass no app to sdcard does not restart it, someone could help me with this proplema?:(
[Optimus One, P500, V General] xtho:
As it was noted above, update your phone's firmware.
[Optimus One, P500, V General] Sergej97:
The solution of unexpected rebooting and switching off.

The root of unexpected swithcing off and restarting problems is in urelaible SD card slot.

I have "swithing off" problem even in the first day after buying, and before installation any application.

In the first time I think it is because of "chinese garbage" sd card.

After I bought reliable hight speed SD card from Transend 8gb/ class 10 problem still reproduced.

After that I do hard reset, and even after that problem had been reproduced.

Final I realize that problem is in SD card, since it can have different thickness (dimension).

The solution of problem is in putting some piece of paper on SD card, and press SD card to pin with more force.

My Optimus is working 3 days without problem, and unexpected rebooting!!!

Have a nice day, and sorry for my english.

p.s also I have a latest firmware V20d.
[G2 and Desire Z General] PatrickHuey:
that when my screen is closed and the keyboard is hidden, where ever i touch on the screen the screen and the entire top part of the phone moves when i touch the screen. its like my screen isnt tight. im not talking about the hindge opening, because obvioulsy what horse has been beaten to a pulp, but the screen itself. i apologize for the rant, but i just want to see if anyone else has the hate as well. only thing wrong with the phone!
[G2 and Desire Z General] Vandam500:
I do not have this problem. You probably have a defective unit.
[G2 and Desire Z General] PatrickHuey:
your screen isnt loose just a tad? i might just be over thinking it. i mean i just can feel the the screen just move a little when i type on it.
[G2 and Desire Z General] rohit275:
I too have never had this issue...you should take a look into that.
[G2 and Desire Z General] dadewy:
Just pushed on my screen MUCH harder than I would in normal use and it didn't so much as budge. Think you might have a bad device.
[G2 and Desire Z General] wileykat:
Yep me too,.... My hinge is definitely loose but there is no movement whatsoever when the device is shut.

Warranty!!!
[G2 and Desire Z General] FrenicX:
Mine does that too. My wife's does not and my original one which I warrenteed already didn't either. But my replacement does.

The plastic casing must be slightly warped enough to misalign the little bumpers.
[G2 and Desire Z General] Dazmck90:
Yea I have this to, really annoying. I had one of those clip on cases on my phone for a while , it might have been that which made it loose.
[G2 and Desire Z General] DrBarrell:
It depends on which way you are holding it when you push on it, if you hold it perpendicular for example it has this issue.
[G2 and Desire Z General] OoTLink:
Mine will rock sideways if you try (and if you're tapping around on screen you MIGHT feel the gap on the left side change), it's not all that much though - and the 3 G2s I've used were all like that.
[G2 and Desire Z General] PatrickHuey:
yeah, thats what i mean. like the way the hinge was made, it doesnt quite sit the phone flat on the keyboard piece. im glad i see other peoples g2s have it as well and im not the only one. its mainly when the phone is in portrait and the top left part of the screen is touch it rocks just a tad.
[G2 and Desire Z General] androidcues:
My condolences to all who have these petty little problems..and i mean that..no sarcasm at all here...

Even with that...and the ballyhooed hinge hysteria...

Is this not the greatest phone ever made? For real? Sure..its no Dream snappy impenetrable...but its still a suhhhhhhhweeeeet phone.

[G2 and Desire Z General] ScooterG:
Sarcasm noted...

For a phone with such great build quality/feel, something like the OP's problem (and mine) is fairly annoying. This feels like an executive class phone...for the first few weeks. It is a sweet phone/device. Too bad it's not perfect like my Vibrant, errr Nexus S, err.... Still waiting for the "perfect" phone. :p
[G2 and Desire Z General] OoTLink:
lol :D

I was hanging out on Slickdeals and saw all the G2 love (yes, people really loved getting their phone free on cyber monday).. then a thread came up for the HTC shift.. and all the sprint guys were bashing it.

:D:D

It's the same damn phone. :D

Still makes me laugh.
[G2 and Desire Z General] DrBarrell:
Best phone I have ever owned without a doubt, not a huge fan of the Z hinge but without it the keyboard wouldn't be so flush and ergonomic, its a small price to pay for superior user-friendliness :-)
[G2 and Desire Z General] snoopdobb:
I have to agree with all the DZ/G2 love here. It's a fantastic phone. Aside from VERY minor issues with the hinge tightness (though, there seems to be some 'hardware hackers' working on that! :), this phone is as close to perfect as I can imagine. I *love* having a hardware keyboard, and it's waaay better than the G1. (Though a ctrl/alt key would be nice for ssh sessions!).

Why would a phone need it? Wouldn't battery life just suck?

Sent from the key to my world.
[General Topics] ErOR22:
Sure, if you want a portable console lol.

The response speed would be great thought, and camera will be able to record in full HD without trouble. But, the software will need to be programmed to take advantage of the dual-core processor.

As for the battery, not necessary. The cpu will throttle back its speed a lot, and a dual-core might be able to drop really low and remain fully operational which will require less battery. Also the new dual-core cpu nanometer architecture would most probably be lower which means better battery consumption but at full load (like when playing graphically intensive games) battery probably won't last long. Still thought, new battery technology will need to be manufactured soon to keep up with this new phone technology. Next you'll see are dual-gpu phones lol :D

I'm waiting for the 2011 CES to see if anything dual-core will be announced before dropping $800 on a phone as I would love such a device, just for fun.
[General Topics] ceg1792:
CES is just next week right?

They've already announced one phone to run it, I just think technology is getting crazy with portability. My computer still has a 1.6ghz processor, these new phones will undoubtedly surpass my poor system. Ha.

Sent from the key to my world.
[General Topics] vbetts:
One thing that the makers of the chips take into consideration, is power usage. And it's easy to see that too. I'll use desktop cpus and laptop cpus for example. Intel and AMD's 6 core designed both have a TDP of under 125W. Old single core pentiums had a TDP higher than that, and were much bigger in nm range. Laptop cpus now only use at the most, 1/4 the tdp of a desktop cpu.(Not as fast though)

Other than that, right now I can bet that there is no multi-threaded apps available, and is Android really able to take advantage of a multi-core system? Probably not on it's own.
[General Topics] ErOR22:
HAPPY NEW YEAR people!!

Yeah, CES is just next week. I know they announced some phone but I would like to know when they are coming so I know if I should buy the best thing right now or not.

I wouldn't have a clue if Android can handle multicore processors but maybe the new Honeycomb version of Android will enable this? If this is the case then maybe this phones will come March/April....sigh

And yeah, TDP of this chips will be lower then current chips. I bet they are working hard to make the best use of the battery.

A multi core cpu does not necessarily use more power than a single core cpu; it's mostly dependent on the architecture.

[General Topics] Akulamenuri:
I think there is a definite need for Dual-Core Processors in phones. Gaming is making a mainstream shift from dedicated handheld gaming consoles to Smartphones. In order for developers to make more robust and graphically appealing games, they are going to need more processing power. Another point is that Dual-Core Processors will help browser rendering speeds. With HSPA+, WiMax, and LTE we are getting some serious downlink on our devices. But if you notice, a smartphone getting 3mbps down and one getting 10 mbps down renders a webpage at the same speed. Right now the processor bottlenecks webpage rendering, not our data connection. With these faster processors it helps eliminate the bottleneck to provide a gratifying web experience to the end-user.
[General Topics] vbetts:
It'll help if the application has multi-thread support. But if the app can only use 1 core/thread, then that's where dual core is useless. Also gaming isn't the main focus of Smartphones, there's probably a huge minority of people using their Smartphones as a serious gaming machine compared to people who are using their smartphone for work, talk, text, or other multimedia.
