Complaints have been mounting over display and audio issues with Google's Pixel 2 and Pixel 2 XL, launched just three weeks ago.
Consumers have reported a screen burn-in problem with the Pixel 2 XL, which refers to embedded functions leaving a ghost-like image on the display.
In addition to the Pixel 2 XL display issue, there have been numerous reports of high-pitched noises and strange clicking sounds occurring during calls on the Pixel 2.
"The demand for Pixel 2 and Pixel 2 XL has exceeded our expectations, and we're thrilled with the positive reaction to our new phones, both from the reviewers who have tried and tested our devices thoroughly and from consumers who are switching to Pixel," said Mario Queiroz, vice president, product management at Pixel. "We take all reports of issues very seriously, and our engineers investigate quickly.
The company will provide updates as soon as it has conclusive data, he said.
The Pixel 2 XL uses pOLED screens, which can display a leftover image when fixed backgrounds or pictures remain on them for a long period of time, said Rob Enderle, principal analyst at the Enderle Group.
Anyone who has a pOLED device "should be using active backgrounds and make sure no one image remains on the phone for an extended period of time," he told TechNewsWorld.
"Some games do have fixed grids, suggesting long-time game players need to watch this as well," Enderle added.
