When I try to write code in the free code camp editor the cursor behaves strangely, it duplicates itself and it writes the same thing in two different places at the same time. Also it doesn’t alow me to errase anything , I think it has something to do with the autoconpletion. I tried with gboard and hawei swipe keyboards and with google chrome and firefox in android 7.
If you are using a mobile device, the default keyboard does not always play well with the freeCodeCamp editor. I recommend you read the article on using a mobile device to view some tips - most importantly, check out the coding keyboards listed as they interface with the editor well.
The recomended keyboard worked well for me, thanks
