Hi,

I'm new to this community anyone got problem on camera of V40 at Android 10? seems mine when I open it freeze for 10-15seconds then its fine but when I change to video the camera freeze again. But switching to front cam doesnt have the issue. Any solutions for this? btw my version is LM-V409N (korean variant) and I tried clearing cache, data, reset app preferences even factory reset.

Just checked and no problem, the stock camera app opens and is ready in less than a second. The current rom I have on my (originally) at&t model is the korean open 409N also.

Maybe check the lg sites for a newer (or even older) version of the camera app? If it's not the app, and everything is pretty much stock, it may unfortunately be a hardware issue...

I think you've misunderstood. I'm not suggesting you change the firmware (I have the exact same firmware you do (well I have 30d and u have 30e - a security update), and no problem with camera app).

I was suggesting you try a different version of the CAMERA APP. LG makes changes to the camera app and makes the *.apk available to download, you'll have to search for LG camera app to find it.

It does seem very unusual you'd be experiencing such a lag when opening the camera app though. You'd almost have to bet that something else you've installed (not stock) that is causing the delay.

Well, in the interest of helping you narrow it down, I can tell you I just used lgup to install the latest korean open kdz (the one you're on, 30e). My camera app opens as it always has with other roms, in less than a second.

so, anyway, I think you can rule out it being anything to do with the specific rom...

thank you currently downgraded to pie but seems the problem exist. It's a camera hardware fault.

I had a verizon V40 and the camera went to crap with the A10 upgrade. Viewfinder was laggy, very similar to what you describe. Also, I think it was telephoto that would show parallel lines across any bright \ white objects. This was a stock rom, stock cam app, and the problem continued after multiple factory resets. Found it hard to believe it was a hardware issue, as it happened immediately after the A10 upgrade. I second year promised the phone...while I did get a brand new phone, it was the US unlocked version. So, as you know, that means no advanced calling (video) within the verizon dialer app and no vvmail.

Found that this GCam mod works. Install the app, then copy the XML (you have to remove the ".txt" at the end, xda wont let me upload it otherwise) to "/internal storage/GCam/Configs/" (make the folders) and then open the app, double-tap the black space to the right of the shutter button, then choose "restore". The app should then work perfectly, with all the cameras available, and no lag in the viewfinder.
