Got my Pro 5 and loving it but wanted to best way to tweak the Vibrate for new messages and email as its kind of weak?

Also how can I just have the one inbox for texts? The personal and notices box is confusing?

And finally why can’t meizu allow you to assign a default sim toneach contact rather than 1 sim for calls and 1 sim for data. Moto do it so why can’t meizu?
