Hey ak1,
Thanks for your post.
Please note, AmpliTube for SAPA (Samsung Professional Audio) will require a SAPA compatible device. Unfortunately, Lenovo and LG devices will not offer SAPA.
Please also note, the AmpliTube UA app is designed solely for use with the iRig UA. This is because of the iRig UA unit's built-in DSP chip. This chip acts as the 'brain' of AmpliTube UA and without this chip, the AmpliTube UA app will not exit DEMO mode.
Read more on the iRig UA hereIf your device does not seem to be compatible with AmpliTube For Samsung Professional Audio, and you own an iRig device that is compatible with Android devices, you can use this iRig with any of the following apps.
*This device will also work with any device which accepts audio input from your device's headset jack or USB port (Depending on the iRig being used.):
