After-hours buzz: Qorvo, Comcast, Starbucks & more

Check out the companies making headlines after the bell Tuesday:

Apple supplier Qorvo popped after a report that Apple's new phones would have more storage capacity.

The new iPhones will start at 32GB, not 16GB, The Wall Street Journal reported. Google parent Alphabet, which owns Apple's rival Android platform, saw its shares dip very briefly after hours.

Shares of Comcast slid after the company announced Xfinity's top-watched On Demand programming for the week ending June 26. HBO's "Game of Thrones" topped the list, the company said in a release. It came after reports that Netflix would be coming to Comcast's set-top box.

Energy companies like Diamond Offshore stumbled after U.S. oil settled nearly 5 percent lower. Worries that Britain's exit from the European Union would slow the global economy, paired with persistent signs of abundant supply, weighed on oil, Reuters reported.

Starbucks shares inched higher in light volume, recovering the day's losses after the company announced that it had inadvertently instituted an up to 30 cent price hike earlier than expected. The company has since repaired the glitch.

Tesla Motors shares fell slightly in light volume after a report of a Tesla Model X that crashed in Autopilot mode. The Pennsylvania Turnpike accident came after regulators issued a report on a fatal crash involving Tesla's self-driving setting.

Disclosure: Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
