White screen, won't turn off!

1. Turn off the phone. When inserting or removing a microSD card with your Samsung Rogue, it is advisable to turn off the phone. Hold down the power button and turn off the Rogue before proceeding.
2. Remove and rotate the microSD card cover out of the way. The cover is located on the right side of the phone (when viewing the screen) toward the bottom.
3. Insert the microSD card into the phone. It is critical to ensure that the "microSD" logo on the card is facing up (same side as screen). Press in the card into the slot until you feel it lock into replace.
4. Replace the card cover to keep dirt and debris out of the device.
5. Reverse the directions to remove the microSD card from the Samsung Rogue. Note that after removing the card cover, you will need to press in on the microSD card to get it to eject from the phone.

The memory card might already be damaged or corrupted. try inserting it in a linux computer, if it still dont recognize it, then it might be damaged forever.

Try inserting your memory card into a different phone, this has seemed to work for several others.

it should work fine. maybe the memory card is faulty.
have you tried the card in anything else to check that it works properly?

i noticed that if you change time of ds..i.e.....put it back a year and that should sort your problem

try cleaning contacts on card with alcohol and retry

try inserting a microSD card when player is turned off then put it on...work most of the times...

Either you are placing it in wrong way or it is corrupt

you need to buy a usb card reader

You need to buy a different kind. i just bought a 4G Microcenter brand and its doing the same thing.
i'd recommend a Sandisk M-2 microSD.
