How do I get my iPhone 4s to turn on?
My iPhone 4s was acting a bit glitchy, like it does sometimes because it's about 2 years old, and so I turned it off with assistive touch. I pressed the home button to go on it a few minutes later and the screen remained black. Siri was talking for awhile but she stopped working a few hours later. I want to be able to get into the phone and access things like my photos and contacts, which I don't believe I backed up on iCloud. I know I should've but I guess I learned the hard way. My lock button does not work so I cannot hook it up to iTunes and put it into recovery mode. The man at my local Apple Store didn't really look at it much and just told me to get an upgrade. Is there any way I can power the phone on and get into it? Thank you.
iPhone 4S, iOS 9.0.1
