Army recruits the Apple iPhone 6s to replace 'poor performing' Android46
This source says that the Android OS freezes and has to be restarted too many times. This is said to waste too much valuable time. By contrast, the unnamed tipster says the iPhone is faster and smoother than Android. He says that when it comes to the iPhone, "The graphics are clear, unbelievable."
The Android Tactical Assault Kit. (ATAC), the iPhone Tactical Assault Kit which is replacing it, and the NETT Warrior (which uses an unnamed Samsung branded phone) all are handsets that connect to a networked radio. Icons on the screen allow unit leaders to track the locations of their soldiers. They also allow users to view video feeds from drones.
The Android models being replaced are unknown, although 9to5Mac suggests that it could be the original Samsung Galaxy Note from 2011. That would explain why the Army's SOC is complaining about the poor performance of their Android phones compared to the iPhone 6s.
Soldiers have taken iOS to the battlefield before. Back in 2010, the Apple iPod touch was sent to users in Iraq and Afghanistan with language modules for Iraqi Arabic, Kurdish, Dari, and Pashto pre-installed.
