If you bought this with a promo, the promo may expire by the time you get the phone and they may not give you the promo. This is one way they appear to get out of fulfilling promos.
After updating my Galaxy Z flip phone, the battery got extremely hot while talking on the phone, the phone restarting by itself and when I fold the phone to watch videos the sound stops working. All of these happened the next day after I updated my phone.
