Why are apps being glitchy?

I was just on my iphone looking at something and my apps that appear on my home screen. When you click them they turn into a shade color. Well I wasn't cocking any app and it turned black by itself and started doing that to other apps also. Is my phone hacked or what is wrong with this thing?

IPhone 6s screen cracked - unresponsive/hypersensitive

Dad got me an iPhone6s 2 weeks ago which fell and cracked yesterday. I noticed after an hour or two that the home button was a bit chipped off and a line went through middle but later on it went to the top - don't know how. Since then, it's been unresponsive/hypersensitive.

I just can't enter the passcode and get access. I pulled the screen protector off (yes, I'm surprised that nothing happened to the screen protector but the screen got damaged and my phone fell on its back not screen).

So yeah I pulled the screen protector off to see if it works - well for a bit it did but after a bit became unresponsive again. Does anyone have any idea how long it would take to sort this problem out? Maybe a few hours/days? And what would the cost be?

I'm really frustrated too that my phone earlier which was an iPhone5 got badly damaged - the cracks were far more worse yet it works perfectly fgs.

Should I buy the Iphone SE?

I'm on a 5s right now. Although rare the 5s sometimes locks up, freezes, etc. Supposedly this was fixed with the SE.

I would get newer like the 6s but the cost is still to much for me. I need a headphone for my hearing aid neck loop anyways.

Besides, why not just get a 7 instead if I could do that? The price is virtually the same.
