Clean everything, run all anti-viruses and restart everything. No need to worry.
I dropped my iphone 4 on my ps4. Everything seems to be working but im paranoid somethings wrong. My iphone also has a rubber otterbox cover on it?
I don't think there is an antivirus on ps4.
Don't worry! The wost thing is theres a scuff on the PS4. If theres a case on the iPhone then it'll be fine & otterbox is a great case company. If it's behaveing funy then go on their tech support :)
