iPhone 6+ playing up

[jamin00]

Gave my 2 year old iPhone 6+ to my daughter when I got the 7+ but now its doing random things and keeps playing up.

The biggest issue is all of a sudden it acts like someone is touching the screen as random stuff opens up and the screens swipes etc.

Any ideas, tried a hard reset a couple of times and it seems to resolve it for a day or so but its not ideal for her.

Anyone come across this before or is it fubared or is it an Apple job and they can fix?

Sounds like liquid damage.
Hardware related.
Bring it to Apple.

What charge cords are you using. My daughters was doing some strange things and I discovered she was using a cheap power supply and cord. She switched back to Apple products and the problem was gone.
