Pixel 4 users hear popping sounds on video playback; another issue affects the Pixel 4 XL's camera

The Google Pixel 4 series was released last Thursday and for some buyers, it is bringing back some unwelcome memories. You might recall that when the Pixel 2 and Pixel 2 XL launched back in 2017, both phones had a number of issues right away. The Pixel 2 XL screen suffered from burn-in that left "ghost images" of the navigational controls at the bottom of the phone. While no software update could fix that issue, the Pixel 2 had its own issues that were manageable. The model was known for the strange ticking and high-frequency sounds that users would hear on phone calls.
Once again the latest Pixel models are making strange noises
The expert's post also said that Google would like to hear from those with a Pixel 4 model that has exhibited this issue. This can be done via the Send feedback option found in the Google Camera app's settings, and by contacting Google's Pixel team directly at Settings > About phone > Send feedback about this device. Keep in mind that this affliction doesn't affect all units.
Meanwhile, another issue has arisen according to a Reddit user with the handle nalrodriguez. This problem is affecting the camera on the Pixel 4 XL, more specifically the camera's algorithm related to white balance correction. As a result, indoor lighting is coming out wrong with red lighting looking yellow and purple lighting coming out blue. The post also noted that this problem has surfaced on three different Pixel 4 XL units. Also, it doesn't seem to affect the Pixel 3 camera or RAW images. This could mean that processing related to the HDR+ feature is at fault; this could be another problem fixable via a software update.
It does seem as though Pixel 4 and Pixel 4 XL users are awaiting a number of different software updates. Besides one to eliminate the popping noise on videos, there could be one to adjust the white balance adjustment on the camera. Then there is the update that will allow users to demand that their eyes be open in order for Face unlock to unlock their phone. Lastly, another update will allow Pixel 4 users to refresh their screen at 90Hz even when the display brightness is set at under 75%.
All new phones can benefit from software updates after their initial release dates, and nothing will ever arrive half baked like the BlackBerry Storm 9530. But the Pixel 4 launch did nothing to change the Pixel's reputation for launching with some annoying issues.
