What is engineering mode on android?

Engineering mode on android is an advanced setting menu on android devices that is accessed by a special USSD code. This hidden mode allows the user to perform several tasks including performing various tests and tweaking the settings.

The menu is not available to access using any settings or app in android. You need to key in the special USSD code on the dialer to access the android engineering mode.

How to Activate Android Engineering mode?

You can either use the USSD code to access the engineering mode on android or use an app to access the menu. The USSD code to access the menu might be different on different android devices.

Also, not all android devices may provide the USSD code to access the engineering mode and you might need to root your android. Here are the methods to access the android engineering mode.

1. Use USSD code to activate Andriod engineering Mode

Accessing engineering mode using USSD code is different from one Android smartphone to another Android smartphone. Also, the settings, and opting you get in this method are limited.

  1. Open Default Dialer app on Android.
  2. Dial *#*#3646633#*# or *#446633#.

2. Use app to activate Andriod engineering Mode(no root)

Another method to access android engineering mode is to use apps. There are several apps on the play store you can install on android to access the engineer mode. But, most of them required a rooted device. We are discussing here a few apps to access engineer mode without root access.

Also, you might need a different app for android devices running on different processors(Snapdragon, Mediatek etc).

Access engineering mode on Snapdragon processor

This method work on almost all device running on a Snapdragon processor. In some cases, it is not possible to access the engineering mode using a USSD code.

In such, follow the steps below to access Android engineering mode on the device running on Snapdragon processors.

  1. Open Play Store and download shortcut master.
  2. Open the app and grant the required permission.

This was a quick method to access android engineer mode on different android devices running on different processors and make. Now, it’s time to explore the use of engineering mode. What are the settings and tweaks users can access?

Uses of Engineering Mode.

Apart from changing settings and performing tests, you can use the engineering menu to perform several other tasks which are listed below.

  1. Change LTE band and other network settings.
  2. Boost device audio.
  3. Customize hardware and camera settings.
  4. Increase WiFi range and signal.
  5. Increase Battery performance.
  6. Customize Bluetooth.
  7. Change MAC address of your device.
  8. Change IMEI code of android device.
  9. CPU management.
  10. Recovery Mode.
  11. Unlock some root features without rooting

1. Change LTE band and other network settings

Increasing network speed is one of the basic reasons android users need to access the engineer mode on their device. Changing the network settings and bands and not only help you to activate the high-speed internet but also lets you switch the band from 2G/3G/VoLTE, enable wi-fi calling and others.

Andriod engineer mode allows you to access these band and networking settings at ease and let you tweak these settings to achieve high-speed internet.

2. Boost device audio

Comes the situation when you feel that your android is not as louder as expected. However, the low sound output on Android smartphones depended on several factors. But, you can also use the android engineering Mode to tweak the default audio settings and boost to audio output up to a certain level.

You can also increase the sound of your microphone and change the tone. By using engineering mode you can change audio settings and cancel background noise as well.

3. Customize hardware and camera settings.

These settings under the engineer mode on android allow you to tweak the default hardware settings to boost the performance of the device. Users can boost hardware acceleration and improve graphics as well.

Also, there are several camera settings available under the engineer menu on the device to tweak the default camera setting like default image format, capture the image is RAW mode for more editing option and may more.

However, the available camera settings under the engineer mode depend on the manufacture and Android OS version the device is running on.

4. Increase WiFi range and signal.

Tweaking the default band of the wi-fi can help you to improve the wifi range and signal strength. The settings os usually not available under the standard-setting.

In such you can use the engineer mode to access the SSD and band settings to tweak and boost the wifi signal and range.

5. Increase Battery performance.

Android devices are battery hunger devices. the apps, bloatware, services running in the background are the huge consumer of batter and other resources.

The android engineer mode allows you to disable, delete and limit these resource-hungry apps and kill the unused apps without even rooting them.

6. Customize Bluetooth.

The engineering mode is also useful to boost the Bluetooth reception strength and quality. The mode allows you to increase performance and perform different tests such as TX-only tests etc.

7. Change MAC address of your device.

MAC address or media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.

This is a unique number of every android device used to identify the device over a network. Usually, there is no option available to change the default MAC on Android.

Using the engineering mode on android you can change the MAC as well. This allows the user to bypass access control lists on servers or routers, either hiding a smartphone on a network or allowing it to impersonate another network device.

8. Change IMEI code of android device.

Every smartphone in the world has a unique identification number called IMEI(International Mobile Equipment Identity). This 15-digit unique number is used to identify the device on the network by the carrier provider.

An improper rooting or anomaly while rooting may cause the device to lose the IMEI number. This may eft the device useless. In such, the engineering mode is used to restore or change the EMI number of the device.

9. CPU management.

By using engineering Mode you can control and view CPU performance. If your device is rooted you can also overclock your CPU. You can view CPU memory utilization, accurate temperature, etc

10. Recovery Mode.

Recovery mode is a runtime environment boot mode on the device where the device is booted in the BIOS mode. This mode helps you to perform different tasks related to rooting, wipe cache, factory restore and other primary tasks.

You can also use the engineer mode to boot the android in Recovery mode as well.

11. Unlock some root features without rooting.

Rooting is a process that allows you to unlock some extra features, remove default apps, uninstall bloatware etc.

But, rooting a device is always risky and it may leave the device dead. Also, rooting the device will void the warranty of the device.

The android engineering mode allows you to assess some root features on the device avoiding the damage of the firmware of the device.

How do I exit engineering mode?

You can exit the engineer node at any point by simply going back on the device. Also, you can restart the device if you are not able to use the back button.
