This should be looked at from several aspects
1. System: BlackBerry’s system is relatively unique and difficult to get started, but it is very in-depth; Symbian system is easy to get started with, but it is too old. , the operation is incomparable with BlackBerry, especially in multi-tasking and running speed, BlackBerry has an absolute advantage.
2. Workmanship: The workmanship of BlackBerry is very fine, provided that you are not buying a refurbished machine. There is no big difference in workmanship; Nokia's Finnish and European version has the best workmanship, followed by the Asia-Pacific version and Hong Kong version, and the mainland version has the worst workmanship in the world.
3. Software: BlackBerry has less software, most of which are paid software. Symbian has a lot of software, but in fact there are only dozens of practical ones that can meet the needs of basic smartphones.
4. Price: Since BlackBerry is not officially launched in China, the supply of goods comes through informal channels. Some people say that low price is the advantage of BlackBerry. I can tell you responsibly that new BlackBerrys are very expensive and there are very few on the market. It's cheap because it's a refurbished machine. Nokia has them on the market so I won’t introduce them.
