New Delhi, Apr 13 (IANS): With the promise of “a new smartphone every month”, Bengaluru-based consumer technology company CREO on Wednesday launched its first smartphone "Mark 1" that runs on an indigenously-made operating system (OS).

The 4G-enabled device, priced at Rs.19,999, runs on the company's proprietary stock Android-based operating system called FUEL OS.

The smartphone device with in-house developed hardware and software will soon be available on the company's website creosense.com and with e-tailer Flipkart.

"In our endeavour to make smartphone that is more than just the sum of great specifications, we have built FUEL -- an operating system that will give a new phone experience every month with features that deliver on both -- performance and functionality,” Sai Srinivas, CEO and co-founder of CREO, said in a statement.

The Mark 1 comes with a sleek metal body protected by Corning Gorilla Glass 3 on both sides with 2.5D curves.

It comes in a gun-metal black colour with a 5.5-inch Quad HD display, 21-megapixel rear camera and an 8-megapixel front camera.

The device is powered by 1.95 GHz True Quad Core Helio X10 processor with 3 GB RAM and 3100mAh battery.

Mark 1 has a 32GB on-board memory which can be expanded upto 128GB and supports duel SIM.

Apart from a unique operating system, the smartphone has compelling features like "Retriever" -- an app that never lets you lose your phone -- and "Echo" -- a voice-based answering machine system completely independent of carriers and devices.

It also has "Sense" -- a universal phone search that finds what you are looking for when you double tap on the home button.

The device comes with multiple camera modes like Live-photo, 3D selfie, slo-mo videos and Time lapse, among other features.
