Smartphone Secret Code (Social media)

Tech News: Smartphones have become a part of our lives today, but when they slow down or the camera doesn't work properly, we immediately rush to the service center. Sometimes this problem can be solved only by software or hardware testing — that too without handing over the phone to an expert! Surprisingly, there is a hidden system in your phone itself that can reveal every problem.

If you are a smartphone user and often wonder why the phone is hanging repeatedly, why the screen is blinking, or why the battery suddenly runs out, then now you will get the answer to this from your phone itself. And for this, no app is needed, nor any technical knowledge. You just need to know some special dial codes.

Samsung users: Your phone will speak for itself

If you have a Samsung smartphone, just dial #0#—and a secret testing menu will open. In this, you can check the display color, touch response, camera, sound, vibration, and many other sensors. This feature can give you a live report card of the internal condition of your phone. Yes, note that if Auto Blocker is on, it will be necessary to turn it off first.

Solution for Oppo, Realme, Vivo and OnePlus users

For testing in these brands, dial #808# (Oppo, Realme, OnePlus) and #558# or ##7777## in Vivo. This opens the service mode in which you can check the functioning of the camera, mic, screen brightness, sound, network, and sensors. Now you can decide for yourself why the phone is slow or why the battery suddenly drops.

Xiaomi, Redmi and Poco users are also not far behind

For test mode in these brands, dial ##6484## or ##4636##. This code helps in testing every part of the phone—like the screen, camera, vibration, sound, or network. This is an easy way to understand the problems of your phone without the help of any tech expert.

Special codes for Infinix, Tecno and Motorola users

Entering #9646633# in Infinix and Tecno phones opens MTK Engineer Mode, in which you can check network, audio, headset, signal, and much more. For Motorola users, the ##2486##* code opens the phone's system diagnostic tool.

Now be smart, check your smartphone yourself

Through these hidden codes, you can know the reality of the phone, and that too without spending a single rupee. Now you will not have to stand in line again and again, nor will you have to depend on the service engineer. The real way to use a smartphone is to become a smart user!
