I have an LG Optimus M. It says the SD card is not installed. I have 2 of them. I reformatted both and it's still saying that. My computer recognizes both SD cards but not my phone.

Hi Everyone,
I had the same problem, and fixed it by very gently bending the Micro SD pins up a little. See the picture below, remove battery first, get a very small screw driver or other implement and one at a time bend each of the 8 pins up slightly, you do not have to bend them much so be very careful. Make sure none of the pins are touching when finished. So the cause of the fault in my LG Optimus GT540 phone was the pins had flattened and were not contacting the contacts on the Micro SD Card well enough. Which is a bit of a design fault really because my original card stopped working because of this and ended up fried. I done the fix above when the new card I bought and checked that it worked on my computer, but when I put it in my phone would come up with the message SD Card removed.
I have an LG Optimus - 1_12_2012_9_02_18_am.jpg
Hope this helps!

Remove The SD memory card Then re insert it againe and remove it then re insert it...
Do that several times 5 to 10 times,then check if your mobile has found it.
The memory base of your mobile on the board has some rust or dirt,thats why you keep remove the SD and re insert,to try to the dirt while you are removing and inserting

Phone does not recognize sd card

Make sure that the SD card itself is not bad.

If you know the card works, try to see if the device will let you reformat the card in the device, if it does not see the card at all you may have to reformat it in a computer - doing in the device is the preferred method though. If you do need to do it in a computer you will need to find out if the card should be in the FAT32 or NTFS format.

How do i change my internal memory settings for LG optimus e400?

Internal memory is different than SD card memory. You only have 800MB free on your phone's harddrive, you still have 1GB of space unused on your SD card. Today's apps are large, some are even 1GB big! I would go and purchase at least a 16GB card for your phone. They are around 10 bucks now a days. Then on your phone, go to your settings and select the big apps, there should be an option to move them over to the SD card.

I have a lg optimous. What does it mean when it keeps say yor sd card has unexpectedly been removed. It does this like 5 times a day.

What i did to fix it was i took out my battery fr a few minutes then put it back in and turned it on and didnt touch any of the buttons for a few minutes and it stopped doing that hope it helps (: Was this answer helpful
it's either an issue with a batch of SD cards that shipped with the phones (in which case user a different SD card) or it's an issue with the formatting of the SD card as shipped (in which case, reformat the existing SD card)

How can i set one of my songs as my notifications tone on my LG optimus black (p970) phone ? need help asap please!

This is a feature not available by default you may download a third party application that does exactly that (and then some).
I recommend "Ringdroid.
1. Launch the Market application
2. Search for "Ringdroid"
3. Download and Install the app to begin using it.
4. Launch the app and begin browsing the songs on your SD card that you'd like to set as your ringtone.
5. Edit the Song and Save it. After saving your edit, you will be asked to set it to a specific contact or as your default ringer.
