Possible reason for low volume

[deviant.ones]

I noticed alot of people saying they have the stock screen protector on and that is what I did for the first 3-4 days until I noticed that there wasn't a cutout for the speaker. I removed mine and the volume has at lease doubled. It is stupid but alot of people don't think about little things like that and most people choose to leave on the stock protectors until they find a better one but for this phone you should take it off or attempt to cut out the whole that needs to be where the speaker is. I used my InvisibleShield off my mogul and with a tiny bit of trimming it is fitting perfect and works great and now my Pro is obnoxiously loud with the audiopara3 done.
