My new ringtone had unexpected result that no matter how high I set the volume, when someone calls it plays at the right volume only for about 1, maybe 2 seconds, then it drops much below 50% - visually estimated from volume slider I'd say somewhere around 25% - and I have to set it back after the call or risk missing it. Unfortunately I hate the default ringtones, so I've kept mine. I've never had or seen, or even hard about this kind of problem, but it would seem like a badly thought, possibly undocumented, feature gone bad. My phone and the system version are: Huawei Y560-L01 Android 5.1.1 EMUI 3.1 Lite - In case this has something to do with it - I have no idea what it is, expect that my friend told me it's some new system of Huawei that alters the underlying Android system; and as it's also listed within system info view. I made the ringtone by downloading a YouTube video, converting it to MP3 with Switch Free, then clipping it to start at chorus - the program used for latter didn't have such option, so no normalization or other changes to the audio were applied - I can't figure any reasonable explanation why my ringtone itself would cause the system to do that, but just in case it matters. Please, could anyone offer an explanation and perhaps a fix, even just a guess? I'd be most thankful.
