FAQ
Buy GlobalROM or GlobalVersion?
Detailed response

How to distinguish the real global version from the interlinked Chinese?
list of symptoms

How to determine RU version when buying?
On the RU version there is no side of the red sticker "Global Version" and the back of the box is all in Russian

How are you doing with autonomy?
3070 mAh is not a fountain, but enough for a day. Energy consumption is highly dependent on the usage scenario.

How many hours does the screen have a battery?
5-7 hours, depending on the brightness.

What is there with the roll-off of 4G Internet?
On firmware below 10.2.9.0 often there was a spontaneous shutdown of the Internet (all-inclusive, but the traffic does not go).
1 treatment option (temporary): switch to flight mode and back.
2 treatment option (more radical): forcibly switching from 4G to 3G.
Starting with firmware 10.2.9.0 uses a new modem, fixed the problem.

Does the phone eSIM?
Not. In our phone no eSIM chip.

Does your phone have a notification LED?
True, the LED is really not. Instead, there are AOD (Always On Display) notifications.

Why are there no notification icons in the top bar? They appear and disappear ...
So conceived in MIUI. All notifications are in the blind.

What's up with PWM?
He is. Flicker of the screen is not visible. Individual susceptibility, from complete immunity to eye fatigue in half an hour.

Is it possible to get rid of PWM?
Currently we are working on DC dimming (already available in developer firmware). To whom it is strongly necessary - there is a crutch:OLED Saver
UPD: available some Anti-flicker Mode, is activated through*#*#3225#*#* in the native dialer. In the opinion of the positive effect is.

Does the recording of telephone conversations work without dancing with a tambourine?
Yes, it works out of the box. This is a MIUI chip and bans 9 Android does not hinder it.

Does the protective glass interfere with the fingerprint scanner?
No, it does not interfere. Optical scanner. With very cheap and low-quality glass options are possible ...

Is the sound in wired headphones missing?
Yes it is.In detail.
There is a suspicion (1, 2) that Telegram is to blame, in the settings you need to disablevoice recording when approaching.
It is also one of the reasons the blademay beinclusion dabltapom screen.
Solution number 1: use a bluetooth headset / headset.
Solution number 2: connect your favorite wired headphones via USB DAC (example).
Solution number 3: connect your favorite wired headphones through a bluetooth receiver (example).
Solution No. 4 (not verified):patchunder magisk to fix this bug, and some more.

Why does not the aptX codec for my blutuz headphones? Opt aptX Developer settings, but still flies in the basic SBC
Your headphones do not really support aptX. If supported, the appropriate mode to be activated automatically.
In the setting of the developer can be successful only switch between those codecs that support the headphone / headset.
There are headphones, on which the manufacturer forgot to activate APTX blutuz chip configuration, as well as those in which the declared support aptX - originally pure fraud.

Why does not the AAC codec for my blutuz headset? Opt AAS Developer settings, but still flies in the basic SBC
The first possible cause of a similar description to the above stories aptX.
The second reason: Xiaomi supports AAC AAC only for headsets, which are included in a "white" list.

Does the fingerprint scanner work well?
The scanner is not perfect. Sometimes you have to wait 1-2 seconds for it to work. Very sensitive to placing a finger on the screen.
Life hacking: add one and the same finger 2-3 times to improve the operation of the scanner (as different fingerprints).

What is there for the blue bar on the screen?
Some copies at the bottom of the screen have a narrow blue stripe (1 mm wide, a couple of cm long), it can be seen on a black background in the bright sun.A photothis strip. The reason is certainly incorrect assembly of the phone.

Is the display fading?
So far, there have been no complaints. I see no cause for concern.

Does AOD notification work fine?
Work, but not for all applications.In detail.Inferiority can be eliminatedcrutch
Fulllistapplications that operate AOD notification MIUI 11

How to enable / disable NFC from the curtain?
What for? Without unlocking the screen no money from the account not write off, NFC chip negligible power consumption.UPD: On firmware 10.3.1.0, a switch appeared in the blind.

Is it safe to keep the included NFC?
Yes. I recommend reading a goodan articleabout safety GPay payments and the possibility of hidden cards debited from the "left" terminal. Contactless payment systems are adequately protected. Despite the theoretical possibility of fraud, in practice it turns out to be unprofitable and extremely difficult feasible.

What is the sound of the speaker?
A great! Loud and bass.

Bad sound conversational dynamics?
The sound is normal, but sometimes it becomes spontaneously deaf and gurgling, and after a few seconds it is normal again. The problem is purely software: during a phone call, the smartphone somehow switches to the HR (Half Rate) codec and back ...In detail

Why are the speaker holes only on the left side? So it should be?
The speaker is shifted to the left, so the holes are only on the left side. On the right is the proximity sensor.

In the area of ​​the camera something rattles with a light tapping. This is normal?
This is a camera autofocus lens, a completely normal phenomenon.

Why does not the NFC for payment in public transport and in some bank terminals?
Change "SIM wallet" to "HCE wallet" in Settings - additional functions - NFC - position of the security element.

Why is the World card not working?
Because GPay works only with payment systems Visa and Mastecard.
For payment card Peace through NFC install the applicationMirpay

Why is a card constantly untied in GPay?
One possible reason is application cloning. When cloning applications, Google services are also cloned, and GPay does not like it.Decision

Why does not GPay?
In order to operate the payment, shall comply with such conditions:
1. Global / European / Russian version of the phone with the appropriate official firmware
2. Locked (nerazblokirovanny) loader
3. No clones applications
If all these three conditions are not met, the payment is not guaranteed.
On Global ROM (ie pereshito Chinese with unlocked bootloader) NFC В«out of the box" is not working, you need to put a patch for GPAY.
card details, in particular the name, surname of the owner, in the application must be entered exactly the same way as printed on the map.

Why is my contactless VISA / Mastercard does not work in Google Pay?
Not every contactless card works with Google Pay.
To work with your card GPay the issuing bank should be an agreement with Google.

Popularly about PWM, DC Dimming, OLED Saver, Anti-Flicker Mode
Try all "on the fingers" to explain ....

What is PWM?
PWM = Pulse Width Modulation. She PWM (Pulse-width modulation). Method of controlling the current / voltage in the load by alternately cycling on and off. Example of fingers: the LED with a nominal luminous flux of 100 lumens at a current of 1 A cyclically include 1 ms, 2 ms, then turn off. Our vision averages all these on and off, as a result of seeing what is tantamount to flow 100 * 1 / (1 + 2) = 30 lumens. By adjusting the ratio of the length of ON and OFF states get brightness adjustment. In this case, the switching frequency is constant, it is the switching frequency.
The advantage of this approach: the highest power efficiency (power switch is either fully open or fully closed state, thus the energy loss is minimized), no color distortion.
Flaw flicker in the case of LEDs.
1st solution lack: good (multi-stage) LC filter, but it is relatively cumbersome for smartphone used in TVs and monitors
2nd solution disadvantages: to increase the frequency units kHz.
Third decision of lack of: Anti-Flicker Mode.

What is the ripple?
The ratio of the difference and maks.yarkosti min.yarkosti to the average luminance. It can be from 0 to 200%. In the case of PWM and the total absence filter min.yarkost zero and obtain koef.pulsatsy equal to 200%. The smallest and simplest filter prevents the increased frequency to drop to zero emission of the LED, so koef.pulsatsy usually significantly less than 200%.

Do PWM harmful?
Sanitary standards (SNIP)rationkoef.pulsatsy artificial lighting at a level no higher than 20%. Common sense dictates that if there are health standards, the flicker caused by the PWM, is harmful to health.

What is DC Dimming?
Direct Current Dimming (literally: dimming DC). luminance adjustment method based on the linear adjusting the current through the LED (LCD backlight matrix or individually OLED pixel). EXAMPLE fingers on the same LED if it stabilized constant current feed and thus to change its value from 0 to 1 we get A smooth adjustment of its light flux from 0 to 100 lumens (excluding nonlinear function of the current flow).
In old-kind LCD matrices and their variations latest DC Dimming - linear technology backlighting current does besides the gamma correction is not related directly to the pixel driver.
The OLED panels harder ... Either driver (DAC) sets the brightness voltage driver directly display pixels (strictly speaking is the DAC reference voltage pixels) or elevated DAC word length used in the driver - the same result.
The advantage of this method: no flicker / pulsations.
Disadvantage: more complex hardware implementation, the energy losses in the linear regulator current (e.g., at 50% brightness the regulator lost exactly the same as the display goes to glow).

How Does OLED Saver / Anti-Flicker Mode?
Looking ahead to say that in fact OLED Saver and Anti-Flicker Mode from Xiaomi - the same thing.measurementconfirm this.
To begin with we shall understand, that (as) we see. Each pixel of the image - the sum of the red (R, Red), green (G, Green) and blue (B, Blue) color. In the 24-bit image, each of the R, G, B components is coded by 8 bits. That is, for each of the colors have 256 levels from 0 to 255 (call itL - Level). All color components 0 - have black color, all at 255 - white. Now add here brightness (Let's call it B - Brightness) display, from 0% to 100% (from 0 to 1 times). As a result, we will see the display work B * L . How is it that works OLED Saver? And this is where the magic begins! OLED Saver processes the image: recalculates the level of each pixel, the new level is equal to the same .... B * L . But it is necessary to physically display brightness to maximum to provide a full scope of adjustment "virtual" brightness.

Example of fingers: the image in which blue pixels "walk" from 0 to 255, and the brightness of 10%.
In normal Shimei displayed 0 ... 255, the display flickers (the brightness is changing from 0 to 100%, our brain flicker averages so that we see the brightness is 10 times smaller - 10% - our brain sees from 0 to 25.5 ( 255/10).
With the included OLED Saver appears on the display is not 0 ... 255 and 0 ... 25, the brightness is constantly 100% - our brain sees from 0 to 25 (note, rounded).

Advantage OLED Saver / Anti-Flicker Mode: no flicker (or is minimized)
Disadvantage: color distortion and narrowing dynamic range.

Why using OLED Saver / Anti-Flicker Mode distorted color reproduction?
When disconnected OLED Saver / Anti-Flicker Mode pixel driver operates with full scale - levels from 0 to 255, and at this range the inclusion narrows and shifts toward lower values. For example, the brightness levels of 10% are from 0 to 25. Plus, the calculation result of new levels have to be rounded. Plus at low values ​​of the nonlinearity affects light LEDs.

And not the same these your DC Dimming / OLED Saver / Anti-Flicker Mode?
Not! This DC Dimming - ithardware decision. OLED Saver / Anti-Flicker - software "crutch" with the attendant disadvantages.
But what is the OLED Saver / Anti-Flicker - not DC Dimming, if the intensity of each pixel is regulated by the linear driver? (The driver that the transistor instead of the computer, which "seal" between the operating system and device)
Yes, if not a "but."
When the full (initially provided) DC Dimming on OLED display driver (D) sets the brightness voltage driver directly display pixels (strictly speaking is the DAC reference voltage source pixels). That is, with respect to the individual pixel are connected in series, two DACs - pixel driver and driver dc dimming. The total capacity is the sum of two-bit DAC.
And in case of OLED Saver / Anti Flicker - DAC only one - this DAC pixel driver, the magnitude of its output is trimmed predetermined brightness.

there is still cool theme about contactless payments. at Apple know there is such a topic, if you want to pay through the Pay Apple then you do not have to unlock your phone, just by double-clicking the button opens the Pay Apple and all you pay. like that would have a similar theme was on MI9se. Android-it is necessary to look for the very Google Pay application to go into it and then pay. I think can come to realize the-screen using the scanner.

Well MI 9, they have a special a button it is possible to display and launch Google Pay and, in principle, rules.

and may have some simple ways which do not know))) ie that would not specifically look for Google Pay application, allegedly from the Quick Launch.
