Phone doesn't reliably charge

Charge phone, use outdoors ... I have new-in-June moto play *. I like a lot of things about it, but I'm already noticing precursors to the problems of my old Motorola phone that made the phone utterly unreliable within ** months. Specifically, the charge cable does not charge the phone reliably (if I touch the screen or any button while it is charging, the phone stops charging until I carefully plug it in again, and sometimes it stops charging while plugged in with no apparent stimulus) and the screen has (currently minor) issues when outside in high humidity and direct sunlight. (The screen issues are currently very small, like turning on Bluetooth or the top drag down bar not functioning, but my old g** got to the point where it would click rapidly on the screen independently in direct sunlight to the point that I watched it freak out and uninstall one of my apps, so I'm rather sensitive to the issue.) Are there means to fix these issues? Might it be a problem with the individual phone? I have the warranty on the phone -- is there something I can do with that to make sure I have a reliable phone?**Sidenotes: my old phone still functioned properly indoors, and only became unusable outside. Humidity seemed to correlate with problems, but moreso was heat and direct sunlight on the screen -- I could get more functional time out if the phone by keeping it in my shadow. Your phones are very good otherwise -- please figure out this bug so it doesn't ruin the phone for people!

Can I make the phone charge properly? And ensure the screen doesn't get bad?
