iPhone 6s constantly freezing

[spesifikbrush]

I've bought an iPhone 6s last week, to complete my Apple ecosystem. I've been using it with no issues till today. I am on iOS 11.0.3

It started with freezing on the black lock screen, I had to do a hard reset. Right after restarting my phone, it froze on the black screen again. After an hour, it stuttered for a moment, then froze while I was swiping on the home screen.

It is very annoying. Is that a common issue?

Hmm, that shouldn't be common. Did you buy it new from Apple? Did you restore from backup?
Worst come to worst, set up appointment with a genius.

No it is not common. Try wiping out your phone and starting it over as a new iPhone. Most problems go away after that.
