Google uses this robot to check for lags on Android phones
Ever since the beginning days of Android, there was always concern about the platform lagging. Most reviews from that era show the reviewer flipping back between home pages to check for "lag" on the screen. Even today, with Android handsets coming to market with more powerful hardware and constantly updated software, there are still times when complaints are made about the screen stuttering.

According to Googler Fran├žois Beaufort, the company uses a robot built by a Finnish company called OptoFidelity to "measure end-to-end latency of Android and Chrome OS devices." As you can see from the video below, the robot continually taps the screen to measure how the display responds. Beaufort posted about the robot on his Google+ page.

Both hardware and software issues can be responsible for problems detected by the robot. And while there are still occasional lags, the platform has come a long way in becoming a lot smoother. And in the future, perhaps all lags will be eliminated on Android. Machines like the OptoFidelity are one reason for optimism.

Yes, because there are so many Android devices to check, what with it being the most popular mobile OS in the world by a factor of over four.

I dont think it's a popularity contest, it's more of a numbers game... "men arent the strogenst when many, the strongest are the few, and among legions there's always one man that can win a battle "...

Lag shouldn't be a problem in phones like the Note 4, S6, the Nexus 6, or any phone that has a more than capable chip. Obviously with the exception of the 810 which was a dud and the lollipop issues.

Just because you say so doesn't mean the android phones you listed lag that bad. I'm more than certain every phone OS lags to some degree but iPhone users pretend their iPhone never lags despite the rather light weight OS

This should be installed in stores like BestBuy... you come in with a complaint for something lagging - it should find what causes it... period. Problem solved...

I thought you were recommending a device to improve the laggy and allow customer service at Best Buy. For a second, I really thought you were on to something.

It would only find lagging. finding lag sources is a painstaking long process.

I love it how this article puts talking marks around "lag" to quote the slang used around the tech word, but then casually uses "lags" in the headline as an adjective as if that was grammatically correct.

My S6 edge lags but is it a problem or affects my daily usage? Nope... I hate trolls who complain about 0.5 seconds of lag and complains to the whole world as if their phone is unusable and doesn't work anymore. These people needs to grow up...
