Mr Android

I just love Android. The love I have for any device that has Android as its operating system knows no bound. Keep following my gists all the time on this websites and other platforms you will get to see me. :)


  1. I put anti-theft luck and when I changed the sim, it require code or that I don’t remember. I want it unlocked.

    1. Since you can’t remember its unlock code, then you need to uninstall the app. Most times antitheft security apps send your sign up details to your email so check your email. If you didn’t see it then recover the unlock code.

  2. The icon that enable you switch front and back camera has disappeared in my Techno-J7 android phone. It is now only showing front camera and I can’t use it to snap people again except myself. How can I recover that icon so that I can use my camera to take pictures?

  3. My tecno j7 front camera icon disappeared and the sim is detected but the network is not available
    If I put the sim in other phones, it work perfectly
    Please help me

  4. why is this happen to my phone tecno h5, if i diel a call then my secreen will sleep what will be the solition?

    1. Hi,
      I believe this has to do with your sensor settings. Most devices are set that way, try not to cover the top section of your device when making a call. The screen should stay on of not take the deice to a Carl Care center for further assistance.
