The process is much easier on mobile devices than on computers. The safest way to delete an Android phone before selling it or sharing it with others is to do so with a commercial design of Android data. Even if you reset your factory phone and a hacker has access to a professional data recovery tool, you can restore and misuse all deleted data from your phone. Imagine that you have private pictures or confidential data such as news, contacts, documents, etc. They are exposed to spammers or hackers, so they will definitely destroy their reputation completely.
To restore your data after resetting your phone, you must enter security information. When you enter the information, it appears that you or someone you trust has restarted. Make sure you keep everything you want, as everything is deleted by a factory reset. The steps are similar for most Android devices, but here are the two most common.
Go to Settings again, then to Security and activate the phone . A warning screen indicates that the process takes some time and cannot be undone without resetting your phone or tablet. You must also enter your PIN or password before you can continue.
Even if someone wants to restore data using one of the data recovery tools, they must first provide a specific key to decrypt the data. If 5.0 Lollipop or higher is running on the phone or tablet, you can have active Android meid vs imei device protection or factory reset protection. This feature makes the phone unusable for a new owner when it is restarted because you cannot activate it without entering a previously used Google account and password.
A factory restart is very similar on most Android devices. These are the steps for some of the most popular manufacturers. Malware can infect your secondary devices such as your printer without you knowing it. This device can re-infect your computer if it reconnects, even after you have completed the factory restart.
