iPhone 6 Volume
i have an iPhone 6 and when I am listening to music the volume will randomly decrease. The volume bar still reads it is at max volume but it will be very low. It randomly will go back to normal. Sometimes when I get a text it will make the volume go back up but it keeps decreasing out of no where and it is gerting very frustrating. There is no volume limit on in my settings and there's isn't anything out of the ordinary based off of my past iPhones. Does anyone know what it could be or how to fix this?
