Hi everyone ! I just bought  new OSMO mobile.  Battery status indicator still showing red light after 7 hours of charging. I have no idea what to do

That happened to me a few times. After disconnecting  charging cable and reconnecting, it turned green.

It seems that the communication between the battery and the handle is abnormal,  please try to wipe the copper sheet inside the battery compartment with 95% alcohol and cotton swab. Let the alcohol air dry. If it does not work, wipe the battery contact with alcohol and cotton swab.
