This is the beauty of Android though. There is choice.
If you want a front facing camera, don't buy this phone and get one that does - Moto G? You can't expect a low-budget phone to have all of the features of a high end phone. You do get to pick which features are important to you though.
The only issue I have is how much knowledge the customer has up-front. As a front-facing camera is pretty much the norm, I would expect it to be on all phones unless told otherwise.
I was caught out with this by the Nexus range's lack of FM radio (it is an obsolete technology apparently, albeit one that is infinitely preferable to internet radio outside of major cities and / or any place where more than 2 people congregate). It wasn't enough to stop me going back for another one but I would have felt better knowing in advance (I know I should have read the specs more carefully but it is easier to spot the things that are there than the things that are not).
