I just got a Samsung galaxy s9 and the app icon badges is switched on in settings however i cannot see any unread notifications on my icons.
Software version: 8.0.0 G960FXXU1ARBA
Open Gmail click on the 3 buttons in the upper right corner, click on open accounts, click on the account, then click on remove account .When you sign back in you will be prompted to re enter your information
the S9 is very clearly not allowing badge notifications (number count) for email, messages and whatsapp WITHOUT allowing pop up noticfications for the entire message. It keeps defaulting back despite turning the notifications off. this forced notification also accumulates as you receive more messages and blocks up half your screen whether you are busy in another app or not. It is very frustrating! I had no problems with the S6 OR S8 but this S9 is playing up.
This is definitely a flaw and has been reported to Samsung by me. I will be seeing a Product Technician from Samsung on Friday to take him through the problem.
