Karbonn is expected to be among the first ones to launch newer Android One devices in the country.

"Smartphone penetration in India still remains low and we believe there is still a huge scope. We will look at bringing in a device by December-end," Karbonn Mobiles Executive Director Shashin Devsare told.

India is the first country where US-based firm's Android One devices have been launched. Similarly, Spice is also looking at unveiling its second Android One smartphone in the January-March quarter of next year, its Chairman and Group CEO Dilip Modi said.

"Our intent is to offer consumers a wide variety of products packed with features across various price points. We already have one of the most affordable smartphones with Firefox and we will continue to bring affordable devices to the market," he added.

Google is rolling out the programme, which aims to bring affordable smartphone to the masses, across other markets like Indonesia, Philippines, Pakistan, Bangladesh, Nepal and Sri Lanka will follow in the coming months.

It has also included new partners including Acer, Alcatal OneTouch, HTC, Asus and Lenovo, along with Indian brands like Xolo, Lava and Intex to bring in devices with various specifications across price points.

By associating with Google as part of the Android one ecosystem, Intex will offer customers an enhanced experience, something unique in terms of design, pricing and functionality, Intex Business Head (Mobile) Sanjay Kalirona said.

"We are actively working on bringing out the device to the market. It takes about 3-4 months for any final product to be made available in the market," Kalirona said but declined to comment on when the device would hit the market.

However, sources said Intex could unveil its device by January next year.

Analysts feel Android One will lead a fiercer competition in the mid-range smartphone market with firms offering better experience at price points in the range of Rs 6,000-10,000.

While the initial launch of the Android One handsets was done in partnership with eCommerce firms Snapdeal, Amazon and Flipkart, the handset makers would sell them through brick and mortar stores as well, which will further fuel competition.

According to research firm IDC, Micromax, Karbonn and Lava (top 5 vendors among total shipment as well as smartphone sales) together accounted for over 30 per cent of the market (in both cases).
