Bluebird EF550

The Bluebird EF550 Touch Mobile Computer is an innovative full-touch device aimed at enhancing enterprise productivity. The device has a touchscreen display big enough to easily see data, while still maintaining a svelte form factor that won’t get in the way. It’s powered by an octa-core Snapdragon 660 processor, sports a decent 13MP main camera plus a 5MP front-facing camera, and has decent internal storage and battery capacities. The rugged device has TankSmith certification for successfully-completed drop tests, keypad and button durability tests, and both temperature and humidity tests.
