Hi.
1. My HP Sprocket Plus is blinking red and yellow very fast on the charging indicator when it is charging.
2. I can only turn it on when it is charging and it prints blank. When I remove the cable from charging, it can't be turned on.
3. When sprocket is charged, it reflected as 100% battery but when remove it says 0%.
Hope this issue can be solve.
