How to check a used Tecno Spark 20

1. Read the model code. Open Settings, About phone, Model. It must say TECNO KJ5, TECNO KJ5n, TECNO KJ5s. Copies often copy this name too, so this is only the first check.
2. Check the processor. It must be the MediaTek Helio G85. Copies run on a cheaper chip and sometimes rename it, so look at the number of cores and the graphics chip too. The Knowfone app does this for you and compares every part with this exact model.
3. Check the screen. The real Tecno Spark 20 has an LCD at 720 x 1612 pixels. Run the screen colour test for dots, lines and stains.
4. Measure the refresh rate. Set Settings, Display to the highest refresh rate, then run the refresh rate test with a finger moving on the screen. The real phone reaches about 90 Hz.
5. Prove the storage. Settings shows 128 GB or 256 GB on a real Tecno Spark 20. Copies can show any number; only writing data and reading it back proves the real size (how to check fake storage).
6. Check the battery. The real battery holds 5000 mAh when new. See how to check battery health.
7. Test the rest. Most Tecno and Infinix models have no public test code (see phone test codes by brand). Our online phone test checks the screen, touch, speakers, microphone, cameras and sensors on any phone without a code.
