abhishekgautam_WCB13iwk2J I am also facing issues while recording videos in 4K at 30 fps on my 3A Pro. The video either becomes laggy or freezes intermittently during recording. I kindly request the Nothing team to investigate and rectify this issue at the earliest.

srpsinu Has your phone performance improved after using it a few days with 4.0 update? Thank you.

jr6nothing nos4 is smoother and more responsive than 3.2…

If you’ve no issues with nos3.2 there are almost no chances that your device will encounter any issue after nos4 update….

Keep in mind that people only come here/get vocal when they’ve problem with their device… so try to not rely on community/forum posts too much ..
