Hitting UK retailers for the first time, the waterproof mid-range handset is being offered through a number of networks and high street retailers.
A scaled back sibling to the flagship Sony Xperia Z3, the M4 Aqua pairs a 5-inch, 720p HD display with Qualcomm’s 64-bit Snapdragon 615 processor, 2GB of RAM and 8GB of internal storage – expandable via microSD.
Boasting a modest array of specs, the M4 Aqua adds a 13-megapixel primary camera alongside a secondary, 5-megapixel snapper around front.
A 2400mAh battery lies under the hood, with the phone’s ‘Stamina Mode’ promising two full day’s use on a single charge.
Powered by Android 5.0 Lollipop, the IP68 certified device can withstand being submersed in a metre of water for up to 30 minutes without succumbing to a liquidy demise.
Available in black today – white and the Carphone Warehouse exclusive Coral (pink) option will launch in June – the M4 Aqua can be snapped up on £15.50 per month, 24 month contracts with no up-front fee.
These deals, which include the new iD network, see the handset paired with 150 any network minutes, 5,000 texts and a minimalist 250MB monthly 4G data allowance.
