Compatibility
If you are planning a bulk purchase of devices our recommendation is to buy one device and try out the user experience for yourself before placing a large order.
MINIMUM SYSTEM AND VERSION REQUIREMENTS
Processor, RAM, screen resolution, storage, battery life and the general age of a device will affect the overall user experience. Generally speaking, the better the processor and more RAM you can get will give you a better user experience over time.
As usual, please always check for updates.
If you plan to update the iOS version for multiple devices then we would recommend updating on one device first to check that the resources on the device post update are adequate to smoothly operate Evidence for Learning.
Firewall Settings
