Somehow my problem has been rectified. For those looking for a history of my problems, I pre-ordered the Xs max from Verizon, and received it on 9-21. Shortly afterwards, maybe on the 23rd, I noticed low-volume from my max during playback of my music, YouTube, and apps that contained dialogue, and quickly found out that the earphone speaker was not working, although a reboot, or a off and on cycle got it working again. I talked with Apple a couple of times, they did their usual testing, but since I do not have AppleCare they were not inclined to replace my phone easily. So I stated my problem to Verizon, and had a new Xs max within two days, I can’t say enough about Verizon’s top tier insurance, and this is a few times in the last couple of years that I have received a new iPhone from them, after some problems arose. I received my new max iOS 12.0.1 was already out, so I updated, a day or two later my problem persisted, no earphone speaker sound. iOS 12.1 comes out, I update, a couple days later my speaker goes out, this may have happened one more time, but the bottom line is my earphone speaker has not gone out in roughly 10 or 12 days. The only thing I have done different is use my Bluetooth a couple of times, and I switched it off after I was done. I have not turned Bluetooth on in about a week. I know someone mentioned turning Bluetooth on and off fixed their problem, that’s why I mentioned it. Why are some still having problems after the iOS 12.1 update? I’m not sure, and for the first couple days after that particular update I was also, then my problem seems to have been resolved. I would expect that if it was going to happen on my max again, it would’ve happened by now. If it goes out again I’ll report it, but so far so good.
