Err_404NotFound_

It seems that the 4a Pro is getting 4K 60FPS support for the video camera now.

However, the Phone 3a series supports the 4K 60FPS due to the Snapdragon 7s Gen 3 chip supporting it. So please Nothing, add 4K 60FPS to the 3a series!

EDIT: 3a Series and Phone 4a do not support 4K 60FPS video due to the Qualcomm Snapdragon chip not officially supporting the video feature, unlike the 4a Pro and 3, which have near-flagship chips.

ZihaoZhang Sorry about that. My mistake, thinking about 7 Gen 3.

I’ve updated and I see that the 4a Pro now supports 4K 60fps recording.

However, it’s only a partial update because, once again, you have to select either the main sensor or the telephoto lens before starting the recording. You can’t switch from the main sensor to the telephoto lens while recording has already started.

When can we expect the update for the Phone 2?
