Is my Samsung Galaxy A15 5G original?
Short answer: A real Samsung Galaxy A15 5G has the MediaTek Dimensity 6100+, 4, 6 or 8 GB of RAM, 64 GB, 128 GB or 256 GB of storage, a 6.5-inch AMOLED screen (1080 x 2340, up to 90 Hz) and a 5000 mAh battery. Its model code is SM-A156B, SM-A156E, SM-A156M, SM-A156U, SM-A156U1, SM-A156W, SM-A1560 (and other SM-A156... versions). A copy can show the right name, but it cannot change the processor, the real storage or the screen.

How to check a used Samsung Galaxy A15 5G
- Read the model code. Open Settings, About phone, Model number. It must say SM-A156B, SM-A156E, SM-A156M, SM-A156U, SM-A156U1, SM-A156W, SM-A1560 (and other SM-A156... versions). Copies often copy this name too, so this is only the first check.
- Check the processor. It must be the MediaTek Dimensity 6100+. 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.
- Do the black screen test. The real Samsung Galaxy A15 5G has an AMOLED screen: open the black colour of the screen test in a dark room. It must be completely black. A grey glow means an LCD, which this model never had.
- 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.
- Prove the storage. Settings shows 64 GB, 128 GB or 256 GB on a real Samsung Galaxy A15 5G. Copies can show any number; only writing data and reading it back proves the real size (how to check fake storage).
- Check the battery. The real battery holds 5000 mAh when new. See how to check battery health.
- Test the rest. Dial *#0*#: on many Galaxy phones it opens a test menu for the screen colours, touch grid, speaker, vibration and sensors (some versions block it). Samsung Members, Phone diagnostics, is the official alternative.
Knowfone checks a used Samsung Galaxy A15 5G against these exact specs in about 7 minutes: the processor, memory, storage, screen and cameras, then every other part, and answers: good to buy, buy only at a lower price, or don't buy. Free for Android.
