Google will launch its below-$100 new Android One smartphones in Bangladesh soon.

Sundar Pichai, who heads Google's Android and Chrome units, told reporters at a launching ceremony of three new Android One smartphones in New Delhi on Monday.

Google says it plans to roll out the Android One in Bangladesh, Pakistan, Indonesia, Philippines and Sri Lanka in the coming months. Android One smartphones will be available in the above South Asian countries by the end of 2014.

In India, prices for the Android One would start from Indian 6,399 rupees.

All three newly-launched Google Android One dual-sim smartphones in India have a 4.5-inch, 854x480 resolution IPS display, MediaTek processor with 1.3GHz quad-core Cortex-A7 CPU and Mali 400 MP2 GPU, 1GB RAM, 4GB storage space which can be expanded up to 32 GB, microSD card slot, 5 megapixel rear camera, 2 megapixel front camera, FM radio, and replaceable 1,700mAh battery.

The best thing about these phones is that they all run stock version of Android, 4.4.4 KitKat.

Android One smartphones will get automatic software updates from Google.

Google also has done partnership with Airtel, India's biggest mobile carrier. Users on Airtel will be able to download Android updates for free (that is, without being charged for data downloads) for the first six months. Airtel users will also be able to download up to 200MB worth of apps from the Google Play Store every month, which won't be counted towards their mobile data.

Pichai said eventual software upgrades on the Android One phones would come directly from Google. This gives the company better control of the operating system and ensures users get a consistent service.

Another interesting feature is that Android One users will be able to download and watch YouTube videos offline, something not yet available on any Android device.
