I don't know why I suddenly went in and out** and didn't record, all kinds of settings didn't work, and then I suddenly found a problem, and the time ran to 2008! Set the date to sync automatically, and your phone will prompt Do Not Disturb to turn on, then turn Do Not Disturb off! Everything went smoothly and the call logs were normal

If you have a call history problem, look at the time and see if Do Not Disturb is set up correctly!

This should be a minor bug

First of all, describe my Mi2, which I bought in March last year, and recently suddenly hit ** without sound, or there was no sound for a while, intermittently, it's really troublesome. After the three clearances are good for a while, there will be such a problem again, call customer service to send it to test, look at the invoice, it is March 27, 2013, just after the warranty period of half a month, I go.

After a few days of browsing the forum, a brother said that the solution caused me to guess, that is, to pat the head of the mobile phone with your hand, it will be fine, I guess that the microphone is loose. Come to think of it, it's over the warranty period anyway, so it's better to take it apart and take a look. After disassembling it, it turns out that the microphone of the Xiaomi Mi 2 is in contact with the motherboard with elastic contacts, and is not soldered to the motherboard.

If the assembly process is not up to par and the gap is too large, it will lead to poor contact between the microphone and the motherboard, or after a long time, the contact will oxidize, which will also lead to poor contact, so that the call will be unstable.

The solution is very simple, take an eraser to wipe the metal contacts, reinstall it, and then pat the head of the phone a few times with your hand, and it's OK. So far, I haven't had any more problems with my Mi 2 calls.

The above is just my personal method, I hope it will work for you as well.
