This tutorial will list out all the available secret codes of Samsung Galaxy M33 SM-M336B. This budget friendly phone is released on April 8th, 2022.
A brief intro to Galaxy M33 specs
The Samsung Galaxy M33 is a wallet friendly Android Smartphone with pretty decent specs of the time. The only negative thing I can see is the inferior display. It holds a 6.6 inches TFT LCD display in the place of AMOLED one.
When it comes to storage and RAM it has two options to choose, 128GB 6GB RAM & 128GB 8GB RAM. The chipset is Samsung’s own Exynos 1280 (5 nm) and Mali-G68 GPU. On the contrary to premium phones it holds a dedicated microSD slot.
The Galaxy M33 has two battery options to choose like;
- Li-Ion 5000 mAh for International version
- Li-Ion 6000 mAh for India
For Galaxy M33 we get colour options like Green, Blue and Brown.

What are secret codes?
Secret codes are hidden codes on your Galaxy M33 which will help you to configure, to get information or to test an inbuilt hardware functionality which is not possible normally. It’s always risky to play with secret codes without knowing what it will do to your phone, so be cautious.
Please note that these codes may not work on carrier locked phones unless their bootloader is unlocked. Also some codes may not work after some software/security update. So don’t panic when some codes are not working.
