Cheap glass/ screen replacement topic

Is it just me or does this device have the cheapest glass out of any device youve ever owned? Honestly I feel like blowing on the screen will cause some erosion and scratching. I have around 20 huge scratches while using a case and protecting the thing with my life after 1 months use. Anyone else have this problem? Also is just the front glass replaceable or does the entire screen and digitizer have to be replaced also.

Thanks
