Heads-Up Notification Duration?

[me7tarfeek]

Good day all,
Is there a way to increase the duration of the heads-notification? Currently, it shows for around 5 seconds and I want to make it 10 second before it disapear.

Gravity on xposed does that, but the module couses problems to my phones as it is not fully compatible with Samsung devices.

I am currently on Dr.Ketan orea rom for N950F.

Thanks
