It looks like global smartphone makers are betting on bigger screens in 2015 and Google cannot be far behind.
Google's next flagship Nexus phone could be a huge 5.9-inch model called "Shamu".
According to media reports, Motorola is currently collaborating on a new device with Google.
The device is in test phase now and should be released in November this year.
The new model will also have a fingerprint sensor.
With Chinese maker HTC testing a 9-inch Nexus tablet, code named "Volantis", this new development means that Google has two Nexus devices up its sleeve now, reports added.
The hardware and screen size of the final Google product could change based on test results.
