Xiaomi have been very good at releasing firmware updates to improve the functionality of the Fimi Palm.
While firmware updates generally make things better they can also make things worse. I updated my Fimi Palm to the v1122.02 firmware and then tried out a USB-C lav mic. The audio was terrible and I was about to write off the lav mic in a review. However, responding to a comment, I recognised the person who left a comment. They’d made a few comments about the Fimi Palm on my videos. Out of interest I checked out their videos. They had a short video comparing the v1122.02 firmware to the v1122.05 firmware. The difference was the audio recording had gone back to acceptable.
So before I did the review of the USB-C lav mic, I updated my firmware to v1122.05. It transformed the recording and restored the Fimi Palm to it’s former glory.
It was lucky that I checked out the firmware video, or I would have written off a good product in error.
