Hi JPL, Sorry to read your issues. As you have done please contact Banggood and discuss the issues. I’ve not personally heard of the problems you describe, possibly someone else has who can assist with the query re the UI. I’d also recommend checking the thread on the BLF A6 troubleshooting BLF A6 FET+7135 Light Troubleshooting and Mod thread. It may include a similar experience. I’ll do some checking too, and advise if I find a similar issue and answer.
