’s decision to bring its Android Chrome divisions together under Sundar chai should result in greater work between the two platforms, but chai first needs to rein in the fast exping operating system bring some order to the business, analysts said dnesday.

chai, who currently runs the Chrome team, assumed leadership of Android on dnesday when said current Android head Rubin would be stepping aside.

“The success of Android has transformed the wireless industry right along side of Apple ione,” said ff Kagan, an Atlanta-based telecommunications analyst, via email. “That is an incredible transformation, much of ’s success can be attributed to Rubin.”

“That’s why it’s so curious that he is leaving,” said Kagan. “ may never know the real reasons Rubin is stepping aside. This is a very deming job maybe he is simply burned out. The smartphone sector is one of ’s most shining stars. It continues to grow change rapidly.”

Carolina Milanesi, a research vice president at Gartner, said she too was initially surprised when she saw the news, but then decided that it makes sense.

“It’s about the next phase of Android,” she said. “Basically, Ruben’s job is done. The platform is successful now it’s about the ecosystem finding a better way to monetize.”

Android accounted for two-thirds of all smartphone shipments in 2012, according to Gartner, but not all of those phones were created equal.

A number of different versions of the Android OS exist phone makers don’t always install the latest version on new devices. Further, since OS updates are left to phone makers not , phones don’t always stay up to date with the latest version.

New version of Android expected soon

That’s about to get more complicated. Key me e, the next version of Android, is expected to debut at an upcoming conference take Android to version 5, while many phones are still running a version 2.x operating system.

“He needs to stop the proliferation chaos get on a schedule for delivery updates,” said Ted Schadler, vice president principal analyst at Forrester Research, when asked if he had any advice for chai.

The different versions make life difficult for application developers, so chai needs to create an environment where app builders have confidence over the future direction of Android, said Schadler.

There are a couple of other tasks in front of chai, he said.

“He needs to reach out much more aggressively to key OEMs, that’s not just the obvious ones like Samsung but others like Dell Hto make sure they are part of how the platform advances. And he needs to focus on privacy security. [] needs to allow at the OS level an ecosystem of things like mobile device management enterprise level security. Right now it’s just an overlay,” he said.

Unite Android Chrome

Beyond Android, chai is also expected to work on bringing together mobile the company’s Chrome OS.

“In the next few years we will see the Android Chrome segments come together,” said Kagan. “Yesterday was all about separate devices, but tomorrow they all operate together under the cloud. Tomorrow is very different also very rapidly growing changing.”

Analysts say sts to gain if it can bring the two platforms together.

“The benefits are huge,” said Ray ng, principal analyst CEO at Constellation Research, of such a combination. “A common advertising platform, write-once-deploy-anywhere apps, integration advantages in search, ads context delivery, making location-based services much easier.”

As for Rubin, his next step at is unclear. In a blog post announcing the change, rry ge said Rubin would “start a new chapter at .”

“To be clear, Rubin did a great job evangelizing getting Android to where it is,” said ng. “He’s got other great opportunities ahead of him.”
