The Hardware Issue I Ran Into
During my testing, I ran into an intermittent issue where the TFT screen would occasionally turn completely grey. A power cycle would temporarily bring it back, but the problem returned during further use. I also experienced some unusual behaviour from the multifunction knob.
I contacted EPOMAKER support through Discord before the case moved to the after-sales email team. The email team already had the relevant context and video evidence, so I did not have to repeatedly explain the issue from scratch.
After reviewing the videos and troubleshooting information, the case was escalated to engineering. EPOMAKER's V1.11 firmware was intended to address the screen issue, but on my unit it introduced additional problems with the Fn key and backlight behaviour, so I reverted to Version 10.
After roughly two weeks of testing and communication, EPOMAKER confirmed the hardware issue and issued a free replacement. In my case, the support process was straightforward, and I appreciated that the team reviewed the evidence and ultimately resolved the problem without unnecessary repeated troubleshooting.
