iphone 6 freezing

My iPhone6 16GB keeps freezing. Some days it will be completely normal.

But every morning, i will have to either restart my phone by pressing the Home & Lock button for a few seconds then i will wait for the Apple Logo to appear.

Even then, the issue is not resolved. So my only choice is to restart it again.

I have tried all the solutions provided on the internet. I have "Reset All Settings", 4 times now. I have had a chat with the Apple Support Team before and they told me to "Erase All Content and Settings" on my phone. I have restored my phone via iTunes. I truly did everything i could with the phone. It is really troublesome and problematic to have a phone which keeps freezing. Its like my phone does not detect my fingers or anything whenever it wants. This probably is a hardware problem. I don't know.

I think the only thing left for me to do is to bring it in to any Apple Store for services. And replace it with a new one. Sigh

The problem is, i have no Apple Store near my area (Mansoura, Egypt). The closest store is 2 and a half hours away.

Help me please.
