Before assuming it's a hardware fault, I'd check whether the issue can be reproduced after a restart, in Safe Mode, or after updating to the latest firmware. Many UMIDIGI issues turn out to be software or configuration related rather than permanent hardware failures.
It may also help to record when the problem occurs and how long it takes before appearing. A time-based approach often reveals patterns that are easy to miss. For example, if the issue consistently appears after 15–20 minutes of use, charging, or screen-on time, that information can significantly narrow down the cause. In that sense, a calculateur de temps is useful because it helps track intervals and durations objectively instead of relying on memory, making troubleshooting much more efficient. |
