I don't know why but there is a network problem in all samsung phones, while opening instagram, youtube, chrome, it keeps buffering.

I have noticed few things after one ui update, that some apps like playstore, YouTube, chrome, Instagram and many others are taking much time to open, or the network is fluctuating very much, is there anyone else facing these issues? If you know the ...

Firstly there is a transparent background, but after the update the background becomes black of apps screen so anyone know how to get that transparent effect back?

What is that recording feature? I didn't understand that

Why i haven't received any notifications of 4.1 update on my phone, if i didn't check samsung members then i will not be able to know about this update, has everyone got notification?
