I’ve been on chat and the phone with T-Mobile Customer Service for at least 2 hours now.
My Samsung Note 9 randomly switches from the correct (central) time zone to eastern time zone as described in this post below from 3 years ago. Obviously this problem has not been solved as the post indicates.
T-mobile wants to attribute it to my phone being a samsung, but excluding myself, there are at least six other individuals at my place of work that this is happening to (all on the t-mobile network) with different phone models.
If anyone out there has a solution to this, please share!
