I bought a 16 GB SD-card for my LG Optimus me P350. There was a game, that I tried to buy (it was jus one dollor, but there was allways a problem with paying), so I found another version of that on the internet and downloaded to my PC and copied it to my Phone's SD card. But now I can not find my SD-Card on the phone to install the game. How can I find it? Thank in advance for any kind of help.
