@Sander I removed and re-bridged whatsapp and messages are already decrypted so, it worked! Big thanks for the support

@Lakotaubp Thanks for the info! I did the installation and, even at indicator-power installation told me I' m on the last version so no update, after rebooting the flash light worked if switching on from the battery switch. Does not work neither from the camera (flash) nor from the torch appplication.
Thanks for the trick! That' s another improvement! Just video recording and playback missing to me to be perfect
