“This particular code I really like because you can actually use it to test the hardware parts of your phone to make sure they’re working or not,” the TikToker explained.
“This phone has dual speakers, so if I click on speaker one it starts playing sound from speaker one to be sure that speaker one is still working.
“And if I click on speaker two, it plays the same sound on that speaker to be sure that that speaker is still working.
“If you’re not sure if your earpiece is still working or not, you can tap on receiver and hear the sound it makes to tell you if your receiver or earpiece still works.

“Also, you can test the vibration and test other features in the phone.”
Samsung’s secret battery code
There is also a secret code Samsung owners can punch into their smartphone that instantly boosts their battery, according to another TikTok tech expert.
Prince Tech Official on TikTok revealed the code, which he says can “save” a Samsung device’s battery life in seconds.
The ‘magic’ code Prince Tech describes is this: *#9900#.
It is used to re-calibrate your Android battery – which is essential to keeping your phone battery healthy, and should be done every couple of months.
Prolonged usage of any device can cause its battery to deteriorate, resulting in reduced capacity compared to when it was new.
However, Android doesn’t consider this degradation, leading to inaccurate battery level readings on your device.
A mismatch between the actual battery capacity and the percentage shown on your device can result in your phone dying prematurely.

But calibrating the battery via the Batterystats Reset button can force the Android operating system to take this degradation into account and rectify the displayed battery percentage.
