Continuing to what
@Tefzors suggested, I went through one post of oppo watch where in the comments they were discussing about using app cloner to change the display size of the app and then sideloading it to the watch, will it be possible on GW4? there are some apps that I'd like and i guess many other would like to use with a better view. Has anyone tried this?
Edit: I tried it with files go app, usually we need to change the dpi to get rid of that popup when we first start the app but I cloned the app with display size of 75% and it was showing the continue button without any other step, I don't know how the app looked on 100%(after we get rid of the popup) but on 75% it is looking pretty good. So you might as well give a try and if necessary add it to your OP.
