Android: how to change or delete the PIN code of your smartphone

Do you want to know how to change the PIN code of your Android smartphone? In this quick tutorial, we explain how to do it in a few simple steps, but also how to delete or reactivate this code if necessary.

There is an increasing tendency to neglect the SIM card code. So either we deactivate it or we leave it with the default PIN code (generally 0000 or 1234). The problem with this code is that when you enter incorrect codes too many times, you will need to ask your operator for a PUK unlock code. But in some cases, the presence of this code can represent additional security. We therefore explain how to change it, deactivate it and reactivate it.SUMMARY
