Hello. This is my first post on any kind of forum. I must admit I'm not very technology savvy to begin with, So I'll explain the best I can... I was interested in changing the sound of my preset lock screen, so I had watched some youtube video or read something somewhere, telling me to download these couple of apps called "Lock Sound Changer," and "BusyBox," from the Google Play Store. I clicked on something and now whenever I turn my phone's screen on I get this bleeping sound for a lock / unlock screen sound. I can't figure out how to disable it. After downloading different stock screen lock sound apps, I still can't get rid of that sound. the new lock sounds are just played over TOP of that one and it sounds hideous... If ANYONE could help me find a way to disable this, it'd be greatly appreciated. Thank you!
