[Q] game to test phone
So I'm looking for a phone for my mom. So I went to the store, took a look at the phones and they all seemed to perform well (like mine when I tried it at the store) but I don't want to take it home, install a game and have lag while playing it. So is there a game I can install at the store and see how well the performance of the phone is? I know that wont factor in real life use but I'm assuming if it can run a cpu/gpu intensive game, then it can handle the other minor things she will do on it with no lag.
