I think you guys need to get over this analyzing everything a girl does, its confusing and pointless; and if you plan on approaching a girl it shouldn't matter what she's doing or looking at, go approach. No one here is in a girls mind to tell you what it means when she is looking at her phone. You could of giving her the creepy vibe so she is using her phone as an escape, she could of thought you were attractive and got nervous so she looked at her phone, or she could simply be receiving a text message.
There are a million of reasons why she could be possibly doing whatever, but you'll never know unless you go approach. Stop analyzing and take action PLEASE
