Why do Samsung Android smartphones often pop up software download tips in the notification bar?

I am very sorry for the inconvenience! Because we can't determine the model of your product, we can't guide the operation path of your product. If the mobile phone suggests that you press *# 1234# to check the model of the mobile phone, or remove the battery to check it on the network access license, you can also check it on the invoice. In order not to delay your normal use of the product, you can also directly call Samsung customer service number: 4008 105858 for consultation after finding out your mobile phone model.

I hope the above will help you, and thank you for your support of Samsung products!
