When children reach the age of needing a phone for communication, parents can consider buying an old phone at a reasonable price. Accordingly, please pay attention to carefully checking the product before giving it to young children for use.
Check the device via IMEI
This is one of the necessary steps to ensure the phone is safe. Open the phone call to display the IMEI range and compare the printed numbers on the SIM. If the two numbers match, it will show that the quality of the device is still good.
Observing the skin outside the phone
You should choose to buy a phone with a new outside phone, without deformed or scratched nails. A phone with many scratches can greatly affect the internal parts and durability when used for a long time.
In particular, pay attention to new screws or whether the screen edges are glue-proof or not is also a way to evaluate the quality of the device.
Testing each function
This is also an important decision to consider buying a phone, be sure to check each feature such as: Screen - need to try increasing or decreasing brightness, keeping an icon and moving around the screen to ensure that no point is paralyzed from the touch;
Voice & Camera - check the outside loudspeaker and microphone to see if the sound is thick, and take a few photos with both front and rear cameras to see if the camera water is clear? Don't forget to try connecting to the Wi-Fi network at and above Bluetooth to ensure the wireless connections are still working well.
Assessing battery health
The phone's battery is also a factor to keep in mind because if the battery is weak, the phone will easily crash. Go to the settings, find the Pin section to see battery status. If the remaining capacity is below 85%, it means the battery configuration is weak and you will have to charge regularly.
Also, don't forget to check the usage information on the device to ensure that the old data has been deleted, and install the phone to the original state.
