If they run out of memory then you need the next bigger phone. That's why the iPhone comes in different sizes. Or you manage what you have. If you have some other phone you should always reveal that in the post as Android memory management is too hard on most folk. That is, slipping in a memory card doesn't "just work."
If the Facebook game needs an app version, always tell the author they need to do that.
I love my facebook games (terrible I know!) and not all the ones I like have google play apps. I am looking for the best solution to play and update facebook games on the go while staying with family or camping or just watching tv on the couch. The second big need is to play movies and the third is google play style apps.
My phone constantly runs out of memory for the apps I do install so good memory size is important.
Can I get this from a tablet or would a cross be better like the surface pro? I have done my head in with the various options and would appreciate help!
