Figured it out, finally. A new sound profile app I downloaded was erasing the starred contacts every night at 11pm.when it automatically activated a night mode I had set up.
Hello I am Corcanoe, the developer of
Sound Profile (Volume control) app.
Sound Profile is able to have different volume profiles for different situations. In each of those profiles the user can set the volumes for calls and notifications, and optionally set the Do Not Disturb to be automatically activated or deactivated when one of those profiles is activated. Also, the user is able to set in each of those profiles which of his/her contacts will be starred (favorite) or not.
The idea is to have, for example, a Profile Night where everything is silent except if my kid or my old grandpa calls or texts me (my kid and my grandfather will be the starred contacts in this case). Another example would be to have a Meeting profile to use at work, where everything is silent except if my coworkers, or my kid's school calls (my coworkers and my kid's school will be the starred ones in this case).
So, as you can see, Sound Profile can (optionally) modify which of your contacts are starred and which not.
If you do not need this feature just follow these simple steps:
If you need specific help just contact me this way:
Open Sound Profile >> menu > Edit profiles >> Select the one to edit >> Scroll to the section "Starred contacts", tap on it and be sure it is switched off (which is the default value by the way).
In case you want to specify some contacts to be starred for that specific profile then switch it on and select the desired contacts.
Keep in mind that the starred or non starred contacts will remain that way until you activate another profile which modifies them. As I said before, not all profiles must have the same contacts defined as starred. It is your choice.
