How to fix auto brightness on Redmi 4A

Frederick Jerome — Sun, 01 Apr 2018 16:07:13 +0000

Hello, guys! It’s been a while since our last post. I came here today to share the method on how to fix and calibrate screen auto brightness on Xiaomi Redmi 4A and Redmi 3S devices. This method should work for other similar Xiaomi smartphones. It’s highly recommended to calibrate the settings in a day-light.

Calibrate screen auto brightness and proximity sensor on Xiaomi smartphones

Ok, so let’s begin with the method. I’ll try to describe each step as clear as possible:

Turn off your smartphone.
Press and hold “Volume Up” button, keep holding it and press “Power” button at the same time.
Release both buttons after short vibration signal.
At this point you should see a special menu on the screen. Most probably it will be on a Chinese language.
To change the menu language, find and tap on “中文” button, it is located in the right bottom column, near the “download模式” button.
Now we will proceed with auto brightness calibration. Find and tap on “Sensor test” > “Proximity sensor”. If the touch screen isn’t working use the “Volume” buttons to navigate and press “Power” to enter.
Now it is necessary to place the phone horizontally on any flat surface. The light sensor should be opened, even better if you can also wipe it with a cloth.
Make sure that there’s no bright light on the phone.
Now press “Calibration” button.
After calibration process is completed, you’ll see “Successfully” message on the screen.
Now you can reboot into system and test your new settings.

This actually helped me to fix the sensor on my own Redmi 4X. Did this guide worked for you? Ask questions and share your results as well as other methods in the comments below.

Make Redmi 3S Prime Take Fingerprint Selfies

Hiram K. — Mon, 13 Nov 2017 23:25:06 +0000

The Xiaomi Redmi 3S Prime is a slightly powerful version of the Redmi 3 and 3S. One of Prime’s distinguishing features is that it gets a fingerprint sensor.

It’s a budget phone all right. Yet it has 3GB RAM and 32 GB of internal memory. Its processing power comes from a Snapdragon 430 CPU and an Adreno 505 GPU.

Also included is a 4,100mAh battery that can see you through a day of intensive use.

A metal unibody design houses the phone’s 5” HD display. The rear sports a 13 MP camera with LED flash (while the one in the front is a 5 MP shooter).

Thanks to the phone’s ergonomics, you can reach the fingerprint scanner that sits in the rear-center with an index finger.

But the fingerprint scanner’s easy accessibility has its cons.

See, when you brush a finger against the sensor, the phone does some unexpected things. For instance, it may start selecting text on the display.

Luckily, there’s an explanation for this weird behavior. Whenever you press the sensor, the Redmi 3S Prime registers a DPAD_CENTER KeyEvent.

In simple terms, a KeyEvent is what tells the software that a user has pressed or released a key somewhere. In this case, the fingerprint sensor is the ‘key.’

Since we can listen in to what the fingerprint scanner is doing, we might as well make it a bit more useful. We will turn it into a selfie button!

First Things, First:

Your Redmi 3S Prime must have an unlocked bootloader. As well as, root access. (If it does not, refer to this excellent guide on how to root the Xiaomi Redmi 3S. It will work on the Prime too.)
You will also need an explorer that can browse system files. You could install MiXplorer or ES File Explorer for this.
There will be some file editing involved. So you should have a text editor like QuickEdit installed.

With that out of the way, make a NANDroid backup because what we are going to do next will modify your system files. And it may result in unintended consequences—like loss of data, or worse.

How to Make Redmi 3S Prime Take Fingerprint Selfies

Before we start, first confirm whether your phone’s fingerprint sensor sends KeyEvent on pressing.

You will have to install the KeyEvent Display app for this. Then give it root access permission.

Open it and press the fingerprint scanner. It should show these lines of code:

^*KeyDown: action=0 code=27 repeat=0 meta=0 scancode=353 mFlags=8 label=‘’ chars=‘null’ number=‘’

^*KeyUp: action=1 code=27 repeat=0 meta=0 scancode=353 mFlags=8 label=‘’ chars=‘null’ number=‘’

If it reads “scancode = 353”, then you are good to go. If shows something different, take note of it. That’s what we will use in the next steps.

Using your root explorer app, navigate to the file: /system/usr/keylayout/Generic.kl
Open the file using a text editor and scroll down to the key 353 (or the code you made note of above).
Deactivate the key by adding “#” at the line’s beginning
Insert a new line reading: “key 353 CAMERA”
Save the file and restart your phone

Long-press the fingerprint scanner to test if takes selfies.

Note – some custom ROMs disable the fingerprint sensor. If that’s your case, you may have to do as follows:

Open a terminal app (like Terminal Emulator) and run this instruction:

grep -rn ‘/system/usr/keylayout’ -e ‘353’

Remember to use the number that works for your phone, if yours isn’t “353.”

What that instruction does is list all files that have a key affecting the fingerprint scanner.

If you some files do appear with the suffix “.kl”—do as follows:

Open each file and scroll to where the sensor’s key appears. (In our case, that would be where find “353.”)
If the key occurs several times, delete those lines and leaving only one. (But if a line starts with “#”—no need messing with it. It’s already inactive.)
Finally, delete any file that has the name “uinput-fpc.kl”

Your Redmi 3S Prime is now ready to take fingerprint selfies.

Have these steps worked for you? Share in the comments below.

Flash TWRP and install Custom ROM on locked bootloader Redmi 3S

Frederick Jerome — Sun, 30 Apr 2017 22:35:12 +0000

In this post you are going to find out how to bypass official unlocking and flash custom recovery and install any custom ROM version on your Xiaomi Redmi 3S or Redmi 3X device. All this without unlocking the bootloader!

How to install TWRP and flash Redmi 3S with locked bootloader

Before doing anything from this guide remember to make backup of your device. Make sure you’re completely understand on how to boot your Redmi 3S / 3X device in EDL and fastboot mode and you know how to use MiFlash. You take all responsibility for your actions!

So what’s the main point of this guide? Just to make things easier! Bypassing official MIUI unlocking is generally much easier than getting the official unlock. You don’t need to request and wait to get unlock permission and the process itself isn’t really complicated than the official unlock. The only thing is that you can’t reinstall TWRP version, that you will flash during this guide.

Required drivers for Redmi 3S and Redmi 3X

Basically all you need is to install the latest version of MiFlash. If you can’t install drivers for different modes, then you can try install them separately:

EDL mode drivers for Redmi 3S: QDLoader+HS-USB+Driver_32-64bit_Setup.zip
Fastboot drivers for Redmi 3S: Android_adb-USB_UnifL_Driver_v1.17.exe

How to enter EDL (download mode) on Redmi 3S and Redmi 3X

When you boot your Redmi 3S device in EDL mode device screen is rather black or turned off. There are two methods on how to boot in EDL mode:

First way is to hold both volume buttons and connect your device to PC.
If your device is in bootloop or hardbricked then try to hold all three buttons for a long time (around 60-90 seconds). First this will lead to reboot, you will get vibration signal, and then device reboot again, now it will be booted in EDL mode.
Another way is to use fastboot mode. Boot your Redmi 3S in fastboot and then type “fastboot oem edl”. Your device will be identified as “Qualcomm HSUSB-Qloader 9008”.
To exit EDL mode just hold the power button for a few seconds.

How to use fastboot mode on Redmi 3S and Redmi 3X

To boot into fastboot mode you need to hold down the volume button and press “Power” to turn your Redmi 3S device. In device manager your phone will be identified as “Android” or “Redmi3S”. You can use fastboot commands to reboot your device in different modes. If you press “Power” button for some time, your device will reboot back into the system.

How to use MiFlash to flash Redmi 3S device

Unpack downloaded ROM in any folder. For example “C:\rom”. In extracted MiFlash ROM version you’ll see “images” directory. Launch MiFlash tool, press “Browse” and select folder with ROM files. Then click “Refresh”, you’ll see COM port of your device. Select “flash all/clean all” mode. Don’t forget about backups! Press “Flash” to start flashing and wait until installation process is completed.

First you must enable the developer options and OEM-unlock in the settings. Then download and flash bootloader patch via MiFlash: RedMi3S_MiFlash_PatchLockedBL.zip (449.6 Kb).

Then boot your device in fastboot mode and execute these two files: doit1.bat and doit2.bat. Download here: RedMi3S_Fastboot_UnlockPatchedBL_specTWRP.zip (21.7 Mb). By doing this you’ll get device with custom TWRP installed. After this you can flash any custom ROMs (including OTA) without unlocking the bootloader on your Xiaomi Redmi 3s device.

Here’s additional information for you:

Start your Redmi 3S in EDL mode.
Flash RedMi3S_MiFlash_PatchLockedBL.zip using MiFlash tool.
Turn off your device and start again in fastboot mode. Attention! You need to start your device in fastboot without booting into the system.
