Can we do anything about the horrible lag in Smart View?

Hi,

I just got my new Samsung UHD Screen and tried screen mirroring my S7 Edge with Smart View to play some Emulator Games. The lag is horrible, it's around one second, unplayable. Is there any alternative or any way to do something about that? Thanks!

Cube i9 Horrible WiFI Speed

Hey Everyone,
I'm getting horrible internet speeds with my Cube i9 (1-2 mbps) while sitting right beside the router. It gets into kilobits if i'm anywhere else in the room. Other WiFi devices are working great. Its using a RTL8723B Wireless n USB 2.0 card and runs Windows 10. I'm really not sure how to fix this problem. I read a lot of reviews before buying this tablet and none mentioned a really slow WiFi being a problem. Have I gotten a defective device? Could anyone help me figure out how to solve this?

Horrible audio over headphone jack. disabled audio "enhacements"

Hello!
I have a rather annoying issue with the headphone jack on my p9000, it is heavily distorted.
When i'm playing music through the headphone jack in my car, the sound is just awfull on this phone!
loud crackling noises and heavy distortion on all volumes, even though the audio "enhacements" that comes out of the box is disabled. I've tried with multiple other phones and cables and i only experience this problem with the elephone p9000.

Is it just me having this problem? if not, any ideas?
