VU Meter with Black outs

Hi,
my VU meter has black outs almost every 10 seconds. Although music is constantly playing the VU meters turn to the left for no reason for a tenth of a second as there would be a scratch. How can this be fixed?
Thanks
Steffen

Hello @Steffi

First try Factory Reset!
Rose device—Settings----System Settings----Factory Reset

Does this only happen on the VU meter screen? Or does it appear on all screens when playing music?
Can I get this symptom in a video?
Please send the video to eunseong96@citech.kr e-mail address.
