Encryption android phone or tablet before sale

Hello friends, I know I can title may seem strange but I promise it is very fair. Before selling a phone or tablet, they need careful cleaning treatment, I do not mean the physical cleaning but cleaning the internal memory so that data can no longer be recovered.
From any phone can recover data even if they have been reset and apparently have no data.
Those who follow our site know very well that Deleted data can be recovered almost completely, especially if the fish is not rewritten memory. A cell is like any other storage medium, the data do not disappear completely deleted data that came in hand to others, surely we can do more harm.
The phone have private conversations, private photos, bank data, sms, data logging on different websites, forums or online stores passwords on facebook, twitter, google, yahoo and many-many more.
The safest cleaning method of the phone is its encryption before resetting to factory condition. In this tutorial you will see how to do this. Please pay attention to what was said in the tutorial. Under no circumstances should you interrupt the process.
For those who want to learn more Understanding encryption, we have some tutorials dedicated to this subject, which is now more topical than ever, in the context of interception of international communications.
AxCrypt, program, fast and very safe encryption of files or documents
Cryptophane, fast file encryption program
TrueCrypt, creation of encrypted containers for safekeeping data on hard or stick

  • Please, make a tutorial about what we need to know and be careful before buying a second-hand phone, with android or ios ... for example: how we realize that an iphone is neverlock and what to do we look before we buy it and many other important things .. (I really want to buy an iphone)
    I think it would be a pretty interesting tutorial for many of us ... (especially since Adrian got his iphone, and promised to do a tutorial like this ....)
    Thanks much and continued success!

  • Cristi can you recommend a program to transfer data from PC to phone.
    I used Snapp but has many bugs.
    Can you help me please nice !!!

  • Hello,
    After executing encryption, files added later (pictures, text files, etc.) will become encrypted by default, or can be recovered with specialized software, even after resetting the phone and bring it to its original configuration, the factory?

    • After activating encryption, all put in the phone and even the pictures that you make, will be encrypted.

      • Cristi welcome
        Pretty please enlighten me on me, I asked Microsoft account login code ????
        and that would be two days and then I close it?
        that code ??? where ???
        please answer me
        thank you

    • If you use the USB data cable that came with the phone, you do not need special software to transfer files from phone to PC and vice versa. Once you install the necessary drivers (which you can find on the official website of the manufacturer) when you connect your phone / tablet PC storing it (internal memory) and SD card (if there is one in your phone / tablet) will appear in My Computer . You'll be able to access the same way you access a USB stick that I connected to PC
      Each manufacturer offers a software suite that allows file management between PC and phone / tablet. Nokia PC Suite Nokia there for you LG PC Suite LG, Samsung of Samsung Kies

      • hi Adrian, an annual s4 Samsung GT-i9500 and when I put it in recovery or download mode

      • Hello George,

        If you want to not have ads in youtube android application, you can install XPosed Installer. Then go to this application on Youtube AdAway download and search there, and install.
        To activate it you have to reboot the smartphone, but be careful, on some devices it causes Bootloop.

        I, for example, I had bootloop.

        Success!

  • Greetings

    I have a big request for you VideoTutorial team. Looking on at 22 and still have not found the time 03 see that there was, and here I searched but could not find what I'm looking for and even pay for such a tutorial at the moment and hope to click.

    So, what is it about. I want to put another soundtrack on a video, and also have the option to sync the sound on the video. If you caught the series made on YouTube by Satan Cartoons ... For example, I made a video file from a certain cartoon a few minutes ago and it has the original sound, and I want to remove the original sound and come up with the new audio (but I repeat, so that I can somehow synchronize it with the video).

    If you think you can do a tutorial on this, let me know, actually let me know and if you can, to know if you are digging on the net and tomorrow night.

    Thank you for your time spent reading this email and I hope you can help me.

    All the best,
    Iulian

    PS I tried to send it via the contact form, but does not send the message.

    • Camtasia Studio is a function of narration, upload video file while running talk microphone. It's perfect for translation and dubbing.
      But I think you know it, you can not sit an audio track over the video that if it is not perfectly synchronized.

    • Some time ago I did exactly what tu.Softul out details just did not remember it but I think it is Ashampoo-Movie-Studio.sau of the software from NCH VideoPad Video Editor.

  • Hello! I come with a question: I have a samsung phone that since I bought it (from the store) I have installed a lot of Custom ROMs .... the question comes now, instead of encrypting it, I can't reinstall the original ROM ? But if I do that, can the files on Custom ROMs still be recovered?
