Machine model: millet MIX2

Malfunction: the phone starts slowly.

Maintenance process:

I received a Xiaomi MIX2. The fault description shows that the mobile phone falls behind, the mobile phone starts slowly, the speaker has no sound, and it can’t record.

The speaker has no sound and cannot record. These two faults appear at the same time, which proves that the audio chip of the motherboard is definitely abnormal. The slow startup of the mobile phone should be caused by the audio chip.

Moreover, the mobile phone was caused by falling. It must be the virtual soldering of the audio chip.

Dismantle the machine, take out the motherboard, and directly replant the audio chip.
