Install missing contacts (or People) on Android Tablet

We had an Android 4 tablet which did not have Contacts or People on it. This is what I did to sync the contacts with the Google account.

It appears that often the manufacturers of tablets don't install People because it's heavily linked with the Dialer app so it just gets missed. Even though you can choose to sync contacts under Account settings, there is no way to access them. After much searching, this is what I did to get it syncing and have all the contacts back on the Tablet:

Go to Google Play Store, search for True Contacts App, by Ondřej Pšenčík  install it and Voilà, all your contacts sycnchronised with your Google account.

Recover missing SIM toolkit icon on Android if it has disappeared

My SIM toolkit suddenly disappeared and after try a number of options, this is what worked for me on an SGII, Android 4.2.2

Enable SIM lock - (make sure you know the default SIM lock code before you do this, check with your operator)
Reboot phone.

That's it.
Apparently on some phones it can reappear by enabling flight mode and disabling it but that didn't work for me.

Hope it helps. Let me know if you found any other ways of getting it back.
