The rolling ball of Blackberry 83 10 can only be used as the direction key, which cannot be confirmed. What's the problem? thank you

Mine has done the same thing, but occasionally it is better, maybe it is caused by software. You can try ALT key+punctuation, which is also possible in Baidu input method mode. Generally, press and hold the ALT key to enter punctuation marks, which will be displayed at any time, proving that there is something wrong with your motherboard.

In the second case, if you can't enter ALT key or only enter a punctuation mark, I suggest you brush the computer. Update a higher system, or a lower system version, try it.

In addition: the buttons below the BlackBerry trackball are integrated on the motherboard. If it is broken, please press enter.

If it is repaired, it is difficult to find accessories.

Never copy, please adopt.
