There is no proximity sensor, did I understand correctly?

[12gauge12]

TanyaJJ,
There is no familiar sensor on top. But during a conversation, when the smartphone is near the ear, the screen turns off in most cases.

12gauge12,I checked on two phones - it does not turn off and does not go out. On Sat I'll take the third one, I wonder if it will work there.

I did not work at the beginning either. It turned out that you need to firmly lean the smartphone against the face. Apparently the shutdown occurs when you touch the display, but it does not work perfectly.

The sensor is, I checked the program. It works when you touch the screen.

Only it is rather not a sensor, but a certain setting.

12gauge12,
Well, I do not know, the sensor boxing program says that the sensor.

[Google2]

in the protective glass there is a hole under the sensor to the right of the speaker hole, the speaker is still the same: mellow:

the screen turns off if the sensor is closed + touching the top of the screen

Can anyone know what a more capacious battery will do?

Glass in DNS bought? There are simply no sensors near the speaker, and the smartphone during a call is only disconnected from touching the screen. Later I will analyze the device and try to prove that the so-called proximity sensor in our device is only a software setting.

[technoid79]

Yes, there really is no proximity sensor. The screen during the conversation is disconnected from two touches.

How to decipher the Chinese recovery? I went and did not understand anything. There is information about him somewhere. I did not find it myself.

[technoid79]

This is not a recovery, but some kind of test mode. The entrance to the recovery is carried out with the shutdown and volume buttons down, but the combination is not clear yet. I stupidly bust these buttons out there.

[dates]

where is pca in brackets etc? I understood correctly?

[technoid79]

Test mode - all in hieroglyphs, recovery, as usual in English.

[dates]

technoid79,
How to enter the recovery?

[technoid79]

I wrote. Power buttons and volume minus. Only in what sequence to press, it is not very clear, at random. It is not always possible to enter the first time.

[dates]

technoid79,
Yes, it turned out to go into the recovery. in the test mode about which you say the last item reset to factory.
