Thank you for the information, I noticed that the SD card you are using is not a recommended card.
To isolate the issue further, would you be able to test this with a recommended card?
I have just tested a Samsung Note 9 (GoPro app on 5.1.1) and was able to trim videos without errors.
Also, we are releasing an update(GoPro app for Android) to address the crashing/connection issues.
Please continue check our website for information.
