Hi all.

I've been able to record in 1080p resolution at 120 fps through app called Ultracorder. As a bonus is encodes in H.265 codec which promises half of the byte rate when compared to the H.264 with similar quality.
Not sure if possible in free app (you can try) but I've been using paid version which after latest update allows to change fps and surprisingly I can set 240 fps (although it looks like 120 fps with doubling of the frames to reach 240).
Video looks super smooth and crisp when played at 25% speed.
No luck with higher resolutions, only 30 fps available

Looks like the 120fps on FHD is legit as there's notable difference when slowing down the vids on 60fps and 120fps. But the quality is still kind of bad lol. BTW Thanks.

Shame this phone is 2 generations ahead of my Nexus 6p but my Nexus 6p can do 240fps slow motion but the V30 appears incapable

I believe the stock camera app is recording 240fps at 720p. But in a very very bad quality and cannot zoom. (Quality is worse than the sony recording 960fps)

Thanks for your post, I downloaded Ultracorder as well and made a video comparision between slow motion modes which I uploaded on Youtube and I´m not allowed to post because I have <10posts.

The internal slow motion camera always records on 720p 240fps with no options of changing the framerate, but you can choose the normal and wide angle lens. The wide angle lens footage looks worse than normal lens though.

In the Ultracorder App you can also choose 1080p with 120fps with the normal lens. It works fine and enhances the quality a little bit.
You can also choose 1080p 240fps but if you record with that setting, you get a file with 160fps and dropped frames. I thought maybe the memory write speed was too low, so I also tried recording it on my Sandisk Extreme MicroSD with the same result of 160fps.

In Ultracorder you can max. choose 30fps with the wide angle lens.

Are you sure this is true because my Nexus 6p actually gives you an option to choose 240 for slo more and it looks a lot smoother than the V30 slo mo. I'm pretty sure V30 only shoots in 120fps

Yes, the footage is 240fps you can choose the playback rates
1/2
1/4
1/8
directly in the LG V30´s media player while
1/8* 240fps= 30fps playback rate
Also I inspected the file in windows and it was 240fps. My V30 runs on Android 8.0 security patch 1.9.18 I just received it yesterday
240 fps (Bilder/Sekunde)

I realized why. Shooting in regular camera produces 240fps while shooting in wide angle mode only does 120. I'd been shooting slo mo in wide angle only.

And for some reason the new GCam (and the mods based on GCam v6.1) kinda ends up recording 1080p240 instead of 720p240 when you set it to 1/8th slow motions speed.... Even though i ONLY have a 720p240 entry in the media profiles, otherwise only 1080p120...
Playing that video then (which is generally already pretty damn dark) is also kinda laggy, so either camera or SoC arent capable of that

Could our lack of 1080p240 possibly be due to a hardware issue such as the write speed of the storage medium in use, or the method of connecting the camera to the SOC? I was thinking largely of these being essentially a computer at it's core, and if the storage devices aren't on a fast enough bus, it could lead to dropped frames. My other thought is if the camera is connected to a slower bus, then it would result in frames being dropped due to not being able to get the data transferred off the camera fast enough. Essentially a lack of bandwidth issue...
