Rollme s08 screen flickering and gets black

You are completely right. O pushed the buttons while i was seating in my surfboard, waiting the waves to come…
But let me tell you i use another watches, not smartwatches while i surf, and i push the buttons, and i have no problem with that. For instance i use decathlon 10 ATM, that costs 18 euros, for years, but i cant receive calls☺️… Thanks again!
