Having an unwanted notification can be annoying Spiderriko but we are here to help. You can delete that unwanted message by pressing the right soft key to choose messages on your main screen. Highlight the message you want to remove, select delete then select ok. Please let us know if this information is helpful.
Same problem of not being able to dismiss the failed sent message notification. Will not let me see which messages failed, and can not dismiss the notification. Will dismiss for a minute then pops back up. Have tried powering down, and turning back on.
Thank you for trying this! Please verify that your phone has the most recent operating system installed for us, okay?
