I can confirm 128gb Sandisk 80mb/s microSD working for a short time whenever it feels like it. then it disappears and shows up with a yellow exclamation mark in device manager (device could not be started, error code 10). NTFS and exFAT both equally problematic. my 64GB Samsung EVO 80mb/s works fine.
Any news on a firmware update for this? It should be fixable since it works for a short time.
How do we best contact Chuwi about this?
