This section describes the process of setting up a new tablet. These basic instructions would apply to any tablet, Android or even Apple devices. However, instructions are modeled off the OS Android 8.1.0. If using a different OS, the order of procedures or location of needed files or applications may differ.
The tablet models that have been tested and are actively used with TabSINT are:
- Samsung Galaxy Tab E (SM-T377A)
- Samsung Galaxy Tab A (SM-T380NZKEXAR)*
* This tablet has a USB-C charging port. However, the similar 2019 8.0" Tab A (SM-T290NZSAXAR) has a Micro-USB charging port. The 2019 8.0" Tab A w/ S Pen, 2019 10.1" Tab A, and 2020 8.4" Tab A all have USB-C charging ports.
When a tablet is first turned on, it is required to go through the Android start-up procedure. The following has been customary for setting up a tablet for research or development purposes. Modifying for one's personal use circumstance will not affect it's ability to interact effectively with TabSINT.

Clean and Clear apps
New tablets arrive with many pre-installed apps. These are unnecessary for our applications and clutter up the screen, slow down tablet, and are burdensome with notifications. Don't worry about cleaning up too much. Apps can always be re-installed or turned back on.
- Tap and Hold an icon on the home page until the Remove option appears, then drag and drop the app icon on the Remove icon. Do this for ALL icons on the home screen.
- Scroll to view the remaining apps.
- Arrange applications on the page. There are some applications that Android will not allow to be deleted. Stack those in a Not Used folder.
