I downloaded ardunio droid, as well as acfew other apps that claim to be able to upload to the uno board.
When i do this it says not detected, even when i also plug in tge 9v barrel jack for power.
The OTG cable i have is the type of usb just before the newer type C end, so im usung an adapter to turn the end into type C.
My phone is a android galaxy 8+
Dont want to order an OTG cable with type end as default if my phone itself is the issue.
I have a Galaxy Note 8 (yet...) and Arduino Droid works like a charm.
Make sure your mobile has OTG function and it should work.
And don't forget to check the app permissions
I found the issue basically my OTG cord was how many USB that is pretty much the same as the type C but with those angled edges instead of round, using the little paste that converted it from the mini to the type C in between the phone and OTG was the cause, I dug out my old tablet that didn't need the converter and it worked fine however Arduino Droid it's not installable on how old that tablet was so I went and bought a brand new OTG type c and it works fine now however I still cannot get it to detect the board but it is being powered at least I saw a post saying some Android devices need to have a USB hub in between the OTG and phone to get the board to detect I'm going out to buy one of those today to see.
