Again, use the precision knife to create space and insert a triangle tool.
 
Release the clips and pop the ZTE Axon 7 Mini out of its rear case.
 
The fingerprint sensor cable and power and volume buttons cable are still connected to the motherboard, so don’t try to remove it entirely just yet.

Step 10 (ZTE Axon 7 Mini Display Assembly)
 
Peel the Axon 7 Mini interconnect cable and display cable up from the midframe.
 
Begin too free the 5.2” Axon 7 Mini display assembly by using a heat gun to soften the adhesive securing it to the midframe.
