Phone Display Not Activate When Receiving a Call

• /e/ version: /e/OS 0.18-20210827132306
• Device model(s): Teracube 2e for Canada
• Device rooted: yes

Summary

On September 28, 2021, I received two calls, but I was not able to accept the calls as the display did not activate to enable acceptance or rejection. However, the ring tone and vibration activated.

Subsequently, I phone myself from another phone and the same experience repeated itself.

Via Telegram channel, I was recommended to report this bug.

The problem

Steps to reproduce

1. Receive call
2. Phone ring tone and vibration activates.
3. Neither with unlocked or locked display does the screen to accept or decline the call arise.

What is the current behavior?

As described above

What is the expected correct behavior?

Ideally all three should activate upon receipt of call: (1) ring tone, (2) vibration and (3) screen to allow acceptance/declining of call
