The boys are Google have a good thing going with the HTC fellas. Google is offering up to 50GB of free additional storage on Google Drive for two years on a limited number of HTC models, including the HTC One and HTC One Max, with Sense 5 and up. Developer Editions of the HTC One are ineligible because of their unlocked bootloaders.
To take advantage of the offer, you’ll have to launch the Google Drive app on your device and then hit the redeem button. The offer is valid until January 1, 2016.
