Hi, I have an ATSC tv tuner for my phone and tablets, but the app is no longer on the play store; I managed to find the app, and it opens, but it hangs on the second screen, and I can't move forward.The newest device I can get it to work on runs Android 7.I don't even know what to look for to modify the apk, but I really don't want to have to buy a new tuner...Any help would be appreciated.
