Remember those glory days when phones still had buttons? Before the selfie stick era. I used my phone to send SMS messages and call people. Browse the internet using WAP. Send a hi-def 320x240px picture now and then using MMS. The only pieces of software I had to deal with were the pre-installed stock applications (renamed to “apps” by Apple in 2008). All other internet activities had to be done on a computer.
Today, the phone is a touch screen that allow you to interact with apps. Everything is done through apps. We use them to buy tickets, share pictures with grandparents, access our bank account, post a picture of today’s dinner. So what happens when your favorite app stops working all of a sudden? How do you troubleshoot it?
