Can the microSD used for internal memory be upgraded in the LG Optimus F3?

The LG Optimus F3 has 4GB microSD for internal memory.  Out of the 4GB on the internal memory, only 1.9 are available to user and apps tend to fill it up with additional stuff. Since the internal memory is on a removable microSD there is implication that user can trade up. But can the op sys handle it if I put in a bigger card?

    Unfortunately, the internal storage is an SD ROM chip that is soldered to the main board, and cannot easily be replaced by average users. Although Android will call the internal storage "Internal SD", it actually isn't removable, and is misleading.

    There is a way, if you are able to root your phone, to use an external micro SD card for installing and moving apps. Once rooted, you have to format the micro SD card and create two primary partitions. After creating the two primary partitions, you can use apps like Apps2SD III to move installed apps, and even automatically install new apps to the external SD card.

    The internal memory of a phone is usually not user changeable. It is mostly soldered onto the phones circuit board for reasons including the user not losing the operating system duo to a mistake.

    According to LG website the internal memory for the F3 is 1.24GB

    Therefor the microSD card slot you found is for extending the phones memory, supports cards up to 32GB and in your case has already been used to do so.

    You can change the microSD card to another one offering more storage but you will lose whatever is stored on the existing one e.g. apps user data like pictures, music, ...

    Depending on the cards file system you might be able to transfer it's contents to a new microSD e.g. using a computer and a card reader.
