I’ve got one of these mice:
It is a Logitech V470 Bluetooth mouse and it is about two years old.
Unfortunately, recently the left mouse button decided to not perform any single clicks anymore. Instead only double and triple clicks were possible. This was very annoying.
I decided not to throw it in the trash but try to repair it.
The Dingoo is a really nice device, but unfortunately the MiniSD slot on my Dingoo got broken after a few days. As I did not want to send the Dingoo back and wait a month or so for a replacement, I decided to open it and check if it is repairable.
As you can see in the picture one of the pins in the SD slot has been bent badly. I was able to bend it back such that I could insert my MiniSD card and make it temporarily work again. There is no way of removing it without destroying the slot, though.
Two ideas how to solve that problem came to my mind. Either I could replace the whole slot if I find some place where I can buy a compatible slot that I could solder in as a replacement or I could try to solder a MiniSD-to-MicroSD adapter on top of the broken MiniSD slot. That way I would have a Dingoo with a MicroSD slot, which wouldn’t be too bad. If you know a place where to buy replacement slots or if you know if there are MiniSD-to-MicroSD adapters where one can remove the micro sd card without removing if from the MiniSD slot, please let me know.
