Developers are rushing to fix all the bugs, giving Jo圜on Droid the potential to become the best alternative to physical controllers out there. Still, it's amongst the first ones that do what it does. This app still has a lot of room for improvement, both in its compatibility with devices and performance as a controller. At the moment, it takes a while to load, suffers from delays in inputs, and can't read some files at all. This feature has also yet to become as smooth as possible. These include the Super Nintendo, Super Famicom, and the Virtual Boy. It not only works as a PS3 emulator but also as an emulator for other consoles as well. One of the most particular features of Jo圜on Droid is the support for the Switch Amiibo function, which allows for the integration of interactive cards and figures to work with game titles, such as Animal Crossing. BizHawk is undoubtedly one of the most popular PS3 emulators available.
In this case, the developers encourage users to let them know via email or Discord so they could debug it further.
On some devices, it may not support all the features. The app is relatively new as such, you may experience lagging or bugs with this app at times. Primarily, you'll need to have Android 9.0 or higher, as well as a Bluetooth HID profile. In this stage of the development, Jo圜on Droid is still a highly demanding app, at least if you want to run it smoothly.
