Unlocking the Hidden Samsung Code That Can Test Your Phone’s Hardware
A PHONE expert on TikTok has revealed a secret Samsung code that is “really handy” when you’re wanting to test potentially damaged hardware, such as your speakers.
It can be tricky to determine if a speaker, call receiver, or the vibration feature is working as it used to with day-to-day use. But a nifty code can reveal a behind-the-scenes menu that Samsung owners can use to test their hardware and check if it’s faulty.
Testing Samsung Speaker, Receiver, and Other Hardware Features
The hidden code TikToker @Tech_Overwatch revealed is: #0#. Typing this code into to call maker will automatically bring up a new menu for Samsung owners to use, as shown in the video.
“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 other features in the phone.”
Samsung’s Secret Battery Code for Improved Battery Life
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’s 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.
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.
