Android performance varies based on your device specs. The "No Pro Latency" message in the Jamstik+ app may appear if your device is not optimized for Bluetooth MIDI instruments.
Not to fear! The Jamstik WILL still work with these phones & tablets that display this message.
The recommended and preferred experience is on devices that use Android's Pro Latency features. If you do not see any notification when logging into the Jamstik+ Android app, it means that your device DOES make use of Android's optimizations and will be performing as desired. The message only shows when devices do not have Pro Latency.
