Dark video problem fix - best workaround

[Aleksey]

For permanent fix dark video do following:

You find any short videofile (15-25 sec) (.mp4 work perfect). Change his name to bootvideo and place it in

Code:

\system\etc

directory
Set permisson 644 (rw-r-r)

In file

Code:

\system\build.prop

find string service.bootvideo=0 and change it to service.bootvideo=1
Reboot

Every reboot you will se this video and after system startup no problem with dark video at all.

You can find sample file in attach.

Great work , and thank you so much for posting this. I know many users suffering from the Dark Video Bug will benefit from you sharing this. I would like to add this to my FAQ - of course I will give you the necessary credit.

But do you think you could explain a couple of things , for those among us that dont know how to:

1) "Set permisson 644 (rw-r-r)" - How do we do this? , what tools do we use?
2) "find string service.bootvideo=0 and change it to service.bootvideo=1" - aain , which tool do we use todo this..

Thank in advance

In A1 box there is a file explorer called "root browser". It has root access and has advanced options. I suppose A95X has the same app pre- installed.
Use this.

Long press tapping the file (long press OK or long press left click if having a mouse) will open an advanced options menu.
There you choose "permissions" and you can set the "permisson 644 (rw-r-r)"

Press to open the file build.prop and choose "open as" and it will pop up a menu, choosing open with "RB text editor" you can edit the file.

*when changing permissions on a file you have to reboot so to take effect. In this mod you have anyway to reboot but assuming you added a keylayout.kl file or other and you changed the permission then you have to reboot to make the new permission active.

Many thanks for this Spiros..

Here is the solution of dark screen problem. You have to install SCREEN ADJUSTER and set contrast around -50. Also don't forget to turn on autorun in the settings (swipe from status bar). The only problem is that this app blocks install button (when you try to install any app). But if you are an experienced user and you have Xposed installed try also to install NoOverlayWarning module to disable this warning.

Jazzman_84, bootvideo solution is much better - work fine, don't block install button, don't need any Xposed modules.

Use app Root browser from stock firmware.
Set 644 permission:
   
   

Changing build.prop with RB text editor:

For me bootvideo solution is not good because the contrast becomes badly calibrated. Black color becomes grey. The picture is too bright. Download some test pictures for calibration display contrast and you will see what I mean.
