1. The endurance is really amazing. It is charged almost once a month. At most, two times is enough. 2. Appearance design is also a work of conscience. 3. Good hand feel, including key feedback and overall grip. 4. The interface is simple, with rich shell colors, but it does not seem outdated.

1. The phone book function is too cumbersome. You can only find people one by one. 3. Telecom and dual cards are not supported. 4. The input method is maddening...... 5. The keyboard unlocking and manual locking are not perfect, and the phone is often mistakenly answered or called when it is in the bag.

Perfect backup. I hope that some detailed problems can be solved later.
