We do not have back protectors for every device and apologize for the inconvenience.
If you are using a bumper, we would suggest you purchase one as not all impacts happen on the screen or the sides. However, we rarely hear of any screen shattering from a rear impact.
If you are not concerned about scratches on the back of your device, you can rest assured that the front screen protector and bumper together provides plenty of protection for daily usage as the bezel on the back can protect your phone from direct impact on a flat surface.
We know that many of our customers prefer to use our bumper without anything on the back so they can feel the back of the phone. It offers a feeling of even less bulk.
