Why can't I get pictures off of an 8gb but I can off of a 2gb chip?

The LG620g works with microSD cards, 2GB or smaller. It will not work with higher capacity microSDHC cards.

The LG620g works with microSD cards. Your 4GB card is actually a microSDHC card. While it fits into the slot, it's electronically incompatible and will not work in this phone. You need to use microSD cards, 2GB and smaller.

The box may say you can use a card up to 8GB but since it can only use SD cards (not SDHC), the box seems to be in conflict with reality. Besides, the camera is only a 4 megapixel camera so you will be able to take hundreds of pictures with a 2GB card.

The problem is that your Digital Picture Frame is only compatible with SD cards, not SDHC cards. You bought a larger card for your Digital Picture Frame, not noticing that it was SDHC (or not knowing that it mattered). The new card doesn't work, not because it or the Digital Picture Frame is broken, but because it's not compatible.

Cards up to 2Gb are generally SD.
Cards of 4Gb are generally SDHC.
Cards over 8Gb have to be SDHC.

(There are exceptions. Sometimes, manufacturers make 4Gb SDHC cards but some have errors; they disable half of the chip and sell it as 2Gb, but it's still SDHC. 4Gb cards are almost always SDHC because they're cheaper, but 4Gb SD cards do exist. They are so rare that I've even seen a guru on this site claim they don't. I did own one once, but it was very expensive and turned out to be so unreliable that I had to return it. I don't recommend looking for one, because of the problems.)

Your solution is to go find a 2Gb card, and be extra sure that it doesn't say "SDHC" on it.

Problem: More than 2GB of RAM is installed, yet the 32-bit OS only sees 2GB.

Cause: Memory remapping is enabled.

Solution: Enter Computer Setup (F10) and disable memory remapping: Advanced > Chipset/Memory.

i think you put it back again your 2GB micro chip, its not necessarily to put 8GB, it will not work.. Your sansa e250 is design for 2GB only, your not an inventor to do that... your only a user, if you something stupid on that, its your own risk but for me its not necessary, your not contented with that.. All you have to do buy a new one which a lot more than 2GB and up, right!... Don't be so pathetic to do that things, even the company don't want really to change even the micro chip inside.. They were not selling for that kind of MP3 player... if might be then they will loss profit on their product, youve been pirate on it... hope you understand the situation...

from what i understand, you can only use a 2gb micro sc card, otherwise the games will not play.

No you can't. I tried a 2gb chip and it was too big. But 1gb works just fine and it holds LOTS of pics, the only time I filled the chip was a 2 week vacation to Europe. So just carry several with you.

Start deleting pictures base on how good they are, importance and priority. Then by trial and error delete 50 pictures, download; 100 ... 200. Finally it download ... after 10-15 seconds wait. Total pictures deleted 1700 out of 4200. So there is a limitation on this type of camera with a 2GB chip, you have to stop taking pictures and change camera
chip when the total count reach 2500 + or - 50 pictures.

The chip may be locked - consult the documentation for details. Also, that card is too big for the e260 to read - 2GB or less.
