I have a lg ally that was actually a old phone of my mom's until i can get my upgrade. I tried updating the software but it says I don't have enough memory space. I have a micro sd card in it and it's formatted but how do i know if it's saving things to my card or my phone?? which does it need to be saving to and how do i do it?? I am so confused! I also don't have a user guide to this phone either.
