Chosen Solution

Sometimes when I boot my iPhone 6 Plus, it shows the apple logo and then it goes off, shows the apple logo again and so on… Sometimes it starts after a few attemps and other times I have to force a reboot a few times with Power and Home Button to get it working again. When it starts successfully everything works fine. What could the issue be?

I have the same problem my phone goes to a freeziny mode and none of the bottoms work so I have to simontainiously push both home and power a few times until it starts working wish really gets scary I only had the phone for two years and this happened every time
