Rear light failure indicator problem

[T-Mu]

So couple days ago, my rear light failure indicator and handbrake light went on. I checked all the bulbs from rear and all of them were working. Yes also brake lights, I checked. And here's the weird part. The rear light failure indicator goes on always when I connect my phone into my car charger and when I take it off, the light goes off as well, but the handbrake light wont. So what could be the problem here, it looks like pretty hard to find.
