20+ Best Hidden Android Secret Codes in 2022 (Latest Codes)

Hello Dear Friends Welcome to Gadgetcrispin today in this article we are talking about 20+ Best Hidden Android Secret Codes in 2022 (Latest Codes). Phones don’t have a single master pin to unlock them as each is different to the phone according to what the person makes it when they set it up.

Often times they can have a SIM pin that is default to 0000 or 1234 but that is the SIM cards pin and can be changed by the user. You would clear up more space by either setting the SD card as “Internal” storage, if your device will allow it, or moving all photos, videos, music, etc., (not apps) to the SD card.
