MTK Engineering Mode APK app has been around for a while now. It is an app that is specially designed for phones powered by MediaTek processors.

Most affordable phones in the market today, are powered by MediaTek processors. Likes of Tecno, Infinix, Gionee and others are powered by MediaTek processors. Phones from bigger players like Samsung, HTC, Pixel and others are often powered by snapdragon processors.

Sometime back, precisely a couple of years ago, glo bis was in vogue. At the time, the only measure for android phones to enjoy being able to use GLO BIS (Glo blackberry plan), was to change the android phone IMEI to that of a blackberry.

For most MTK powered devices at the time, changing IMEI was as easy as using the MTK engineering mode app. Till date, this app is still very useful in getting that functionality done. However, this isn’t the case for every MTK powered android phone now.

If you happen to own an MTK powered android smartphone, having MTK engineering mode can be a necessity. Especially if you are more of an advanced user than a basic user.

mtk engineer mode secret codes

To sort-off give you an heads-up, i will be introducing you to the MTK engineering mode app. Thereafter, I’d be sharing some secret codes which are valid for android powers powered by MediaTek processors via the MTK engineering app.

Introduction To MTK Engineering Mode APK App

Although i already shared what the app pretty much entails, I’d like to share with you, some of the functionalities you can perform using the app. If you want an insight before deciding on whether or not to download the app, you should also read on.

To begin, the app is available on the Google play store and can be downloaded HERE.

Open launching the app for the first time, you are faced with 3 options; Android settings, MTK settings and Samsung Settings.

MTK engineering Mode settings

Choosing the Android settings for most devices, won’t take you anyway. Instead, you’d continually be displayed an error.

MTK Settings Mode

Choosing the MTK settings on the other hand, takes you to the Engineer mode. Here, you can test some telephony functions, connectivity options, hardware testing, location, log and debugging, and others.

Under the telephony option, you’d get to find the Antenna Test, AMR-WB on/off, BandMode, SimRecoveryTestTool, CFU, BIP, IMS, LTE Information, AT Command Tool, Misc Feature Config, Modem Test, Network Selecting, NetworkInfo, GPRS, HSPA Info and a host of others.

The Band Mode typically allows you control the GSM network reception for specific sims. By default, you should leave all the options here checked.

In most cases, you shouldn’t toy with any of the options in this category except of course, you know exactly what you are doing.

Under the connectivity tab, you’d find the bluetooth, CDS information, FM receiver, WiFi CTIA and GattProfile. Just as the name implies, this session controls everything that has to do with connectivity on the device.

The CDS (Common Data Service) is often the session where you can check the CDS information, Wi-Fi and Radio information, Network Utility and a host of others.

Under the Hardware testing tab, you can test and edit the Audio settings, edit the camera settings, Test the touchscreen feature, edit the USB functions, sensors and others. Feel free to play around other settings tab available on the app.

Samsung Settings

The third option being Samsung Settings is all often not available in most MTK powered devices. Tapping that option, you’d often be faced with an error message.
