I've attached the APK that I tried to revert to if anyone is interested. I'm trying really hard here, but I'm about to give up and cancel my premium subscription. I also noticed that even though I installed the earlier version, it looks like Spotify updated itself to version 4.3, rendering that fix useless. Back to the main eq screen, it says "Normal" but there's no "disable" function? Clicked on the "details button and nothing there that says "turn me off". It says "Equalizer" and "Open the control panel" then I get a notice that I should disable it if I experience difficulties, but how? I looked at Sound effects panel, everything's OFF. I read turning the EQ off might help, but when I go to the settings, it's not readily apparent to me where the on/off switch is for the EQ. I've tried uninstalling Spotify, and then reinstalling the newest version, the older versions from APK 2.8 (I think?), tried uninstalling the volume booster and just playing Spotify without it (back to square one, an it produced predictable low volume), then reinstalled the volume booster (same headaches). Why does it seem to work for my phone and other music players, but not Spotify? What is the official line on using Spotify with volume booster apps (specifically Speaker Boost Pro for Android)? This takes a couple of minutes and is aggravating. Then I can't get the volume booster to work, unless I restart the phone and then reopen my Bluetooth connection and reopen Spotify again. FX Sound Booster, which was previously known as DFX Audio Enhancer is the Ultimate volume booster for your PC. Also, the volume will randomly drop, even when I don't change the currently playing song to a new one. Yet another namesake of an app that we talked about above, this app is more simple compared to other offerings out there. Then the volume reverts back to inaudible levels. 7) Volume Booster by Vintage Audio Tools. Starting a song with the Speaker Boot will work, as long as I DON'T change the song. The thing is, it works fine for bluetooth audio (I can hear the clicks of my phone over the speakers as I navigate thru the apps) and it works fine with Soundcloud. So I downloaded a volume booster called Speaker Boost Pro. When I tried to use Spotify, the volume was inaudible on my bluetooth speakers. I have a Samsung Galaxy S6 Edge- just bought in October. Why would I continue to pay $120 a year for something that doesn't work right? I have signed up for Spotify premium for a while now, but am seriously thinking about just dumping the whole thing if I can't get this to work properly.
