Is it me or most online reviews suck on phones?

I have been looking at a few phones, and most of them suck real bad..They don't show you around the phones UI..Like how the camera,messaging,phone, dialer etc..A person like me likes to see how well the UI looks on a phone before making a decision. AND THE MOST IMPORTANT OF ALL PART OF THE REVIEW THEY NEVER EVER SHOW IS..The back speaker..TO me thats really important..They don't test out the sound in the video at all.
