The Amazon Fire Tablet earns a 7 out of 10 on our repairability scale (10 is the easiest to repair):

The plastic case assembly is held together by clips and no adhesive, and opening only requires prying with an iFixit opening tool.

The digitizer and LCD panel are not fused together.

All of the screws in the device are Phillips screws.

The battery is modular, but it is held in place by somewhat stubborn adhesive.

Removing the digitizer and LCD panel requires fighting through some very resilient adhesive.

Manufacturer does not provide user-accessible repair documentation.
