Samsung. 1. What is the difference between raw electricity and group electricity?

1. Samsung's original battery, like the fuselage, will have a smell similar to sandalwood (the author thinks it seems more accurate to call it a plastic smell), and there is no such smell in group electricity and fake electricity;

2. The original battery has the words 1-1 1-2 in the groove combined with the mobile phone, the digital height is between 1-2 mm, and the digital color is shiny. There is generally no number at the groove of group electricity and false electricity, and even if there is, the height of the number will be significantly greater than 2 mm;

3. The surface of Samsung's original battery has been matte, and the feel is smooth and delicate; However, the matte finish on the surface of the assembled battery feels very jerky;

4. The "CE" symbol on the label of Samsung's original battery is higher than the height of the trash can graphic symbol on its right. The three protruding teeth at the bottom of the original battery are composed of a flat surface and a curved surface, and the plane and the curved surface are clearly defined, and the surface of the teeth is rougher than the inner surface of the battery, similar to orange peel. The teeth of the group electricity are much smoother, and the surface of the teeth is smooth and bright;

If your phone can be unlocked with your fingerprint, but you forgot your backup password when you set it up to unlock your fingerprint, please do as follows:

4. If the phone has not restarted, then, press Volume + and select Reboot System Now;

5. OK, the phone is restarted, and the partner can already use it;

Precautions: Attention! This method will erase the data, so consider it carefully! But it's simple and effective, and it should be no problem for those who can back up.

Factory reset resolved.
