Samsung has received reports regarding the error.
Information posted on the company's forums indicates that Samsung has been informed of this issue, but the company has yet to provide any specific details on how to rectify the problem for users.
As per details shared on the forums, Samsung's management stated: 'We have received reports of the issue, and the software that users can send to us will assist in narrowing down the problem and finding quicker solutions.'
If the error was introduced in the March 2018 update, the simplest way to avoid it is by not installing the new security patch (if users haven't already installed it).
Currently, there are numerous mobile network packages supporting missed call registration, enabling subscribers to be notified of missed calls when their phones are inactive or when they are engaged in other calls. You can subscribe to missed call notifications from Viettel, Vina, or Mobi networks.
To avoid purchasing counterfeit or low-quality Samsung S9 devices in the market, which is also a direct cause of missed call notification blocking, thorough examination before purchase is necessary. Especially, applying the Samsung S9 IMEI check method we've shared ensures transaction safety, without consuming too much time.
