Hi,
I had my phone some days in my bag on the beach, so some little bit of sand came in little spots such as behind the volume button. I guess this is maybe why my micro usb input doesn’t work properly anymore.
Since this night, it totally shut down. The only form of activity I saw was when I pressed the volume up and the power button and the phone was connected with my laptop - then a black screen came where I could “chose” between three modes. The arrow jumped itself to the different options and it was not possible to select one.
I tried battery charging but as the micro usb is a bit broken this is also not easy.
Thanks for your help!
