Is there a possibility to send a private mail for this kind of information ?
I have never sent any video as is is impossible to. As these are intermittent issues. It does not prevent and so I cannot prepare to get in troubles...
BANGGOOD answered me I have to go in a local repair store. What can they do ? I am sure it is a software issue and need updates.
A local store may restore factory settings ans send an invoice.
What to do ?
