While this device uses the rk3399 it is also enclosed in a tight package
and cooled through the screen and back case. The default rk3399 thermal
limits can result in a burnt screen.
These lower limits have resulted in the existing burn not expanding and
will hopefully result in future devices not experiencing the issue.
