Use of codes
Many of these codes work on both android and iOS devices and so, if you happen to have both devices, go ahead and explore on both devices.
However, there are also manufacturer-specific codes and these are the ones mostly used by repair people in service centers to diagnose issues with the phones.
App developers also use these codes for quick checks and troubleshooting phones in case any issues arise.
Pros of codes
- They allow you to test if any of the phone’s components such as the screen, speaker, and camera are not functioning properly. This comes in handy when you are buying a used phone and want to assess its condition.
- Enables you to view the International Mobile Equipment Identity (IMEI) and phone serial number without having to unlock the phone. Useful when your phone needs to be network unlocked and the IMEI is required to get the unlock code.
- Allows you to easily check the phone specifications all in one place: displays both the software and hardware information.
Cons of codes
- The battery check could fully drain the battery or worse still weaken it altogether. You might want to avoid this lest you buy a new battery.
- You might end up rooting your phone since you have access to its internal workings and this can void your warranty.
Final thoughts
As much as experimenting with these codes might be exciting, one should be cautious because they can lead to some irreversible changes to your phone.
Fortunately, the ones shared in this article are the “safe” ones to use so worry not about any phone trouble.
