通知的卷设置和铃声在垃圾邮件通话后继续开启 -- notifications 领域 和 7.0-nougat 领域 和 htc 领域 android 相关 的问题

Currently running android 7 on an HTC 10, and constantly having spam callers reach my number all day.

Normally when I'm working I have my ringtone and notification volume set to vibrate only. However, whenever a spam or scam caller reaches my number (I don't pick up), the volume for my notifications and ringtone goes back up after the call is declined, so the next scam call blasts my phone at a high volume while I'm working. I've tried blocking the numbers, but these scammers keep calling from different numbers and my phone keeps blasting sounds loudly in the workplace everytime it happens after the first! What can I do about this, or is there a setting that I have not checked?

Never mind, turned out to be the CallBlocker app causing the volume to go back up. Uninstalled that and installed Truecaller instead.
