HELP!!!! slide to unlock, screen and all buttons not working
after i took a photo, my iphone 4s suddenly stopped working.. i press the home button then suddenly it was locked and i can't seem to unlock it. "slide to unlock" isn't working also my "power off" button's not working (good thing my assistive touch is acivated) the initial remedy that i thought of was to turn my phone off in order for it to reset...so under "device" button- (assisstive touch), i long press the "lock screen' button to reset my phone but the thing is i can't slide to power off my phone. are there other remedies for me to do in order for it to work again? i cant even answer all my calls now. pls help 😟
your advice/ answers/ suggestions is highly appreciated. thank you so much.
iPhone 4S, iOS 7.0.4
