The Picture Password feature is available on BlackBerry 10 as well as Android Priv and DTEK60 devices. It will allow you to unlock your device using a unique number and picture combination. It’s a simple to use, as all you do is move a grid to align a number over a specific secret location on a picture. You choose the number, secret location and picture.
Why would you use Picture Password? You are out and about and don’t want anyone to shoulder surf you and easily guess the PIN or password you enter to unlock your screen. By using Picture Password, it is difficult for another person to guess your picture password, even if the person is watching you unlock your screen.
To be able to use Picture Password, you will first need to set up a screen lock that uses either a password or a PIN. Enter your Picture Password incorrectly more than five times, your device will prompt you to enter the password or PIN to unlock the screen.
NOTE: Whenever you restart your Android device you will not be able to use Picture Password to unlock your device. You will have to use either your password or PIN to start your device.
Adoptable external storage provides support to designate your external microSD storage card as internal storage. Only HTC, Lenovo and the BlackBerry DTEK60 provide this Android Marshmallow only feature.
It’s worth noting that if you decide to format your microSD card for internal storage, it will format as EXT4* and encrypt it, so it will only be accessible on your device, as the SD card will no longer be visible.
Follow these simple steps to enable your microSD card for internal storage:
- Settings > Storage & USB
- Tap > SD card (this will under ‘Portable storage’)
- Tap > Menu (top right three vertical dots) > Settings
- You can choose to Eject, Format or Format on internal
- Choose > Format on internal
The microSD will be formatted to make it secure. After formatting, your SD card will only work on your device. It will also erase all data currently stored on the microSD card. To avoid losing any of your data, you should now consider backing it up.
- Tap > ERASE & FORMAT – depending on the type and size of card, formatting shouldn’t take long.
If you receive the following message while formatting:
You open your Android App for the first time and are interrupted by a screen overlay message – a feature called ‘Draw over other apps’. What does this screen overlay message mean? This actually allows part of an App to display over the top of other Apps.
Facebook Messenger is one such App that uses a screen overlay. Apps need your permission to use screen overlays as sometimes they can cause problems, or could trick you into granting it permission to do something you might not want. If you are using Android Marshmallow and you have just installed an App and are greeted with the following dialogue:
“Screen overlay detected. To change this permission setting, you first have to turn off the screen overlay in Settings > Apps” – Click on OPEN SETTINGS
You should now see a list of Apps that use the ’Draw over other apps’ feature. You can tap on any App that is listed to turn off the screen overlay permission.
Updated: Controlling your root settings is very important, especially as it opens your Android device up to the threat of malware. if you are familiar with rooting you will know that you can tweak and modify the way your Android software and hardware behaves. Granting apps root allows you to have vastly more control of your device and apps than without.
You should though be very aware that allowing your Android device to have root access does come with an element of security and privacy risk. Given the risk, SuperSU is often used by modders to control Android root settings on a per app basis.
What is SuperSU? SuperSU allows for advanced management of Superuser access rights for all the apps on your device that need root. It’s that simple!
I’m going to assume you already have a rooted device and that you have an intermediary knowledge of device rooting using SuperSU developed by ChainfireXDA. SuperSU allows for advanced management of Superuser access rights for all the apps on your device that need root.
Here is a quick guide using SuperSU v2.78 SR1, on how to control your Android smartphone root settings:
Updated: If you use an Android device and regularly download and install apps from the Google Play Store, you may have noticed that some apps require device admin rights to be disabled before you can “Force stop” or “uninstall” an app. Device admin allows developers to create security-aware apps that are mainly useful for enterprise settings. These settings (or policies as they are referred too) may stop a user from installing or uninstalling an app for example.
I’ve started noticing quite a few Android mobile security apps are employing device admin rights to their consumer apps. The main reason for doing this is that the AV vendors want to lock down their app in the event some malware looks to disable or remove their security app, but it is also to with defining a generic security standard for mobile security app development.
Glancing through developer forums it’s clear to see (and I’m one of these) that not being able to kill an app because it is using up large amounts of CPU or RAM time, isn’t that useful to us end -users. Apps and operating systems do have memory leakage and probably always will from time to time. So, how do you disable device admin rights for a particular app so that you can enable ‘Force stop’; ‘Uninstall’; ‘Clear data’; ‘Clear cache’; and ‘Clear defaults’ from within App Manager? It’s actually very simple folks:
