I was forced to install a mandatory update (Droid version 9, Kernel version 3.18.91-16068741) for my Samsung Galaxy J7 around 2 weeks ago. Since then, there have been six (6) incidents where my phone rings EVEN IF MY RINGTONE IS SET TO MUTE. Is this a bug with the new update or did the change break a setting? As a last resort, how do I downgrade?

  • Does it always happens or from time to time? Jul 31, 2019 at 21:21
  • It seems to happen randomly.

  • If you were updating from android 8 to 9 than in that case factory reset might be a good option, anyway in case of any update it might be a good to do a factory reset if it causes any problems. Aug 1, 2019 at 14:41
  • Ugh...Did a factory reset yesterday and it just went off now. That didn't work :(

  • Did you restore a backup? Does the issue happen with a selected caller? Might be a case of some whitelisted contact that should be allowed to bypass silent mode?

Try using do not disturb, that usually helps by going to Settings > Sounds and notifications and check that the following are selected to how you want. There are two options:

  • Volume: To adjust the volume level for music and videos, system sounds, call ringtones, and notifications.

  • Do not disturb: Mute incoming call and notification sounds, except for allowed exceptions.

For the Do not Disturb option, check that you are not leaving an exception for incoming calls before enabling because that could be one of the problems too.

Also, as a last resort like you said, you can also flash your phone using this well-explained guide by clicking the link here (don't mind the title, the process of flashing can either upgrade(which you don't want) or downgrade(which, of course, you want) ) which will provide all the resources you need to properly flash your phone.

REMEMBER: I am not responsible if you brick your phone if you follow these instructions incorrectly. MAKE SURE you select your correct device along with the correct ROM you want to use on the SamMobile website, meaning, since you want to downgrade, select a firmware other than the 9.0 Pie firmware, so an older one like one back in 2017. If you don't know how to use Odin, follow this link which will provide you with instructions of how to use it.

ALSO NOTE: To avoid the stress of you permanently bricking your phone, install a custom recovery like TWRP, which will make life easier when you have to deal with a bricked phone.

I hope these instructions were helpful and wish you the best of luck.
