There are multiple complaints on the MacRumors forums suggesting that the camera can take several seconds to load when it's opened, which is a problem for some iPhone 14 Pro owners.
Users are seeing the Camera app take four to five seconds to be activated after the Camera app icon is tapped, with the problem occurring after the camera has been opened. A reader from Macrumors.
I have the same issue with my iPhone 14 Pro (non Max). When restarting the phone and starting the camera app the camera turns on immediately. After closing and opening the camera app it always takes 4 - 5 seconds for the camera to turn on. I've tested other apps using the camera and there it it turns on instantly. I assume this is a SW bug.
If the Camera app is manually closed and reopened, the problem won't occur. It seems to only happen when the Camera app is running in the background, and it isn't a problem that affects all users. The majority of the complaints are from people who use the Pro and Pro Max models.
We ran into an issue with the Camera app that took several seconds to open, but it did not happen every time that we opened the app. The issue is limited to the Camera app and does not affect third-party camera apps when the Camera app is set to video mode.
The issue does not seem to be fixed by the update. Factory resets the device do not provide a permanent fix. Readers of MacRumors speculated that it could be a management issue. A video was shared by a member of the Macrumors forum.
I've just discovered that it may be a RAM management issue with the camera app. When I clear my iPhone 14 Pro's RAM by first enabling Assistive Touch in the Accessibility Settings, then press Volume Up, Volume Down and hold the Power Button until the shutdown menu comes up and then long press the Home Button on the Assistive Touch menu to clear the RAM, the Camera App always launches quickly on the first try. For subsequent camera app launches, however, the app still takes around 5 seconds to open.
Slow loading is not the only problem with the camera. The camera vibrates uncontrollably in some apps. This issue is limited to third party apps.
It is possible that a fix is in the works for the camera issues reported by MacRumors readers. There are a lot of bugs that the new devices seem to be experiencing, and we could soon see an update that addresses those issues.
