It Will Work On All Samsung Mobile Phones..
What’s so particular about this company? Just that the chips they manufacture are really cheap, and that they’re incorporated inside most cheap Android devices. MediaTek is also the company that manufactures chips for almost all dual-SIM devices.
MTK Engineering Mode is an app that lets you activate a series of extra options on your Samsung device. In other words, it lets you do more with devices from Tecno, Infinix, Elephone, Oppo, Chuwi, etc…..
So if you need MTK Engineering App then first find out your phones technical specification wheather your phone has mediatek chips or not. If you have not mediatek chips on your phone then MTK Engineering apps will not work and *#*#3646633#*#* code also not work.
