input question: On a scale of 1-5 (with 1 being least favorable and 5 being most favorable), how would you rate this review? "Can't exit map I used ametro a lot on my previous phone. Installed it on my new one and imported a bunch of maps. I opened a map and now I can't exit it anymore. I can't get back to the main menu. I tried the back and home button swiping gesturing ... No go. I just end up at my home screen. Checked the site but there is no info on how to use the app. I'd like to go for 5 stars. But that's just not possible for an app I have to reinstall every time I want to switch maps."???
