You can try a factory reset to see what amount you start with but very very few apps need over 1GB. The phone does seem to have a memory card slot. Pop a 32GB in there now.

I recently got a LG Escape 2 smartphone and have cconsistently received a message regarding my storage. 5 of the 8 supposed GB's of storage is being taken up by "system data," leaving me with little memory to download apps, etc. Is there any way to rid of this gigantic system data?
