Today, the OS system built by BlackBerry Layer officially stopped operating, and all BlackBerry mobile phones equipped with the system could not be used, telephones could not be dialed; text messages could not be received, and even emergency alarms and emergency calls could not be dialed, and some special programs could not be used.
For BlackBerry users, if they use Models such as BlackBerry KeyOne, Key2 and Key2 LE, running Android, they can still be used, but these phones have stopped updating, and the official will no longer push new versions and fix all bugs.
In 2010, the king of the mobile phone market, BlackBerry, withdrew from the market.
