Im just curious. i have a galaxy s7 and that thing likes to update every 2 weeks, so no problem with the operating system there. using an otg adapter that came with the phone, along with a printer cable (which im reading is working for others with older lollipop) it originally connected but the only thing that worked was music playback through the smp (spider v30) i updated the amp itself through my computer and now it wont connect or even play music at all. i since updated to ever version of the software on the amp through the computer and am having no luck at all. does not make sense to have to buy older tablets and what not.
thanks line 6 for not using wireless/bluetooth technology thats been around for years, or adding a cable(s) with the amp that probably cost you 37 cents.
