Are you selling a phone? A factory reset is not enough!

Are you selling a phone? A factory reset is not enough!

A real drama has emerged on the internet after Avast! tested several used smart devices and managed to "dig out" deleted private information.

Namely, experts from the Avast company bought 20 used phones with a factory reset, to delete all the data, but they managed to get most of the information and content that was in those devices.

How to?

In fact, there is no wisdom, there are a bunch of free tools with which you can restore all files in a few clicks. You may have used them to recover accidentally deleted images, documents, and other important files. This is possible because when you delete a file it is actually still in memory but the information about its existence has been deleted. So another file can be recorded over it, and only then does it disappear.

Every smart device that has the option to reset to factory settings, to delete files faster, uses the classic delete method so that all these files actually remains in the device. You can restore all of these files later with the Recover Deleted Files tool.

How to?

What do people do?

Those who know about this, and who find it interesting, buy a used phone and "dig up" private information from the owner. Of course, if the owner does not know that resetting the phone does not delete the information completely, he can get into an awkward situation.

Since you now know that this is possible, you will do a thorough deletion of data from the phone BEFORE resetting to factory settings. The method is known as "wipe drive".

Data recovery tools are e.g. Undelete DiskDigger and the like.

How to completely delete data from the phone before selling it?

How to change IMEI number on Android phone?

By Administrator
IMEI is an abbreviation of "international mobile equipment identity" and each mobile phone should have a unique IMEI number. You cannot change this number with the operator, but you can temporarily change it on your device. It allows the operator to accurately identify your device and thus enable/disable network services. Also, you can use the possibility of changing the IMEI number, at least for a short time, if you know exactly what you want, but I leave those ideas to you because this is an educational article.

The Internet on mobile devices is becoming more popular and has more and more users. As mobile internet expands, so do mobile browsers. Although the devices themselves already have built-in basic internet browsers, new browsers are constantly appearing. The reason is that each of the programs brings something new and useful. For example, Opera Mini is most popular on older phone models that use Java applications, while on Android platforms Chrome , Firefox ,  Dolphin , and xScope are more represented.
