Your Galaxy S7's slow-motion video stutters? You are not alone!


The Samsung Galaxy S7 is among the few handsets on the market capable of capturing slow-motion video at 240 frames per second. The exclusive club is joined by the S7 edge, the Google Nexus 6P, and the newest iPhones. While the feature is more than welcome among enthusiastic or budding slo-mo cinematographers, there seems to be a problem that Samsung needs to attend to.

Galaxy S7 owners have been complaining about stuttering issues during slo-mo 240fps recording. Now that the handset is released and more people can report their experience, it has become apparent that the issue is more common in units powered by the Qualcomm Snapdragon 820-processor, which are sold in the United States. The majority of Asian and European markets have their Galaxy S7 powered by Samsung's own Exynos 8890 chipset. Owners of the Samsung Galaxy S7 edge haven't complained of such problems.

Samsung hasn’t officially replied to complaints yet, but is probably investigating the issue. Hopefuly, an update can patch things up. Unfortunately, there's nothing users can do for now, although it is said that those recording videos to external storage should opt for fast, high-quality microSD cards that are able to handle the large data streams generated by high resolution 240fps video.

The issue can be seen in action in the two slo-motion videos inside the gallery below. The stuttering occurs in the slowed-down parts.

I found out, that if the S7 records 240fps for ten minutes, the first four minutes are not that much affected by this horrible and unnecessary bug, which should not ever exist at all. But after that, the last six minutes, and especially the three final minutes of that video (camera excluded from power saving), the lag is so much worse, that even 60fps would look more smoothly. #askTheTechLord

I can not stress, how deeply I hate this bug. If I see 240fps in the specifications, I do not expect a random, disgracefully unnecessary bug to mess up a good moment captured. Even 60fps is better than this horrible bug.

Wow, that's a huge disappointment. Somebody recorded slow motion with an S7 in a very cold envoirnment, and the indicated battery temperature was 14.2’º of celsius. Some frames were repeated and some moments were skipped. That's HORRIBLE.

I've noticed stuttering on my S6 edge while recording in 120 fps... It's probably a software issue, since it's been happening more often ever since the Marshmallow update.

Wow, the 2015 flagships are also affected? I tested it, and that was not the case. Do you mind uploading your video somewhere?

A U3 class 10 card is the best. I have the 64gig PNY and it flies. The slo-mo playback jutter is gone after the T-Mobile update yesterday.

So its was software issue. Love how some moronic fool always say its hardware whitout taking time to look at all the info.

That's what you get if you switch to recording to SD card without a really good card.

This was in reddit 1 month back. https://www.reddit.com/r/GalaxyS7/comments/49u52j/galaxy_s7_slow_motion_video_broken_on_snapdragon/ There were some threads even before where you can find some evidence. https://www.reddit.com/r/GalaxyS7/comments/499gri/galaxy_s7_slow_motion_new_york_city/ Now AA copied it to an article, and PA copies AA and makes another article. What's the point of tech journalism? Everyone completed their 'in-depth' reviews and nobody noticed! That's why I never trust these sites for reviews. All they do publish some junk for clicks.

Were any of them using SD cards? Because this seems like some frames are getting skipped. This is usually due to either small buffer or slow storage.

Exactly. This is what people get for using those slow 128gb micro SD cards.

20. tyrionTheWise unregistered

Update: I did some searching around and it seems like the phone is using CPU for video encoding, instead of codec. As a result, the CPU usage is getting 95% or higher and ultimately it can't keep up resulting in the missing frames. Don't know if that's the case with exynos too. But this is really bad for at least SD 820 based s7 users. I don't even know of Samsung bothered to use the inbuilt codec on the SD. And this also means it may not be fixed in future, or maybe it can't be fixed if the codec block is missing from the chip itself. All in all, this is extremely poor work from Samsung, They shouldn't release two variants if they can't keep them on par. These kind of disrespect and 'f**k you' attitude of Samsung to its customers drives me away from them. If they don't improve, at least I won't buy their phones again, and many others won't too.

samsung should just stick with exynos leave snapdragon to the rest of the oems

Thats quite sad as the built in codec of the SD is like 10 year more advanced than what samsung do using only cpu/software on the exynos. As long as they did not remove the codec block from the chip as Tyrion said they can fix it with a software update. Still we did not experience any stutter when we tested a client SD820 device vs the exynos we have in store so this is strange.

"Thats quite sad as the built in codec of the SD is like 10 year more advanced than what samsung do using only cpu/software on the exynos." You are forgetting that the Exynos has a codec too. And that codec is capable of 1080p@480 fps. The Mali V550 MP8 is a monster. "Still we did not experience any stutter when we tested a client SD820 device vs the exynos we have in store so this is strange." Didn't you say you lived in Canada. So how come your client has Snapdragon. You got caught lying once again. And before you say it was G5, please note that G5 can't shoot 720p @ 240fps. Just stop trying. You are a bad liar. I would say I believe you less now but I don't believe you even a bit, so that isn't possible. It's quite hysterical how bad of a liar you are and your poor attempts at lying.

S7 edge been back order since its came out we only received 3 for the store and 1 demo. So client was tired and gone buy one full price in the US thats why :) what G5 have to do with this news? G5 is faster all around sure but i did not talk about G5 in this news plz stick to the subject. lol yeah beleive what you want if you would be nicer i could easily prove everything i said like i did before with Maherk but as you are an ass i wont waste my time on you. Just stick to the subject next time.

Well it has been reported that the Edge version doesn't suffer from the slow mo frame skipping and both have an identical SD820 chip so maybe they can fix it via an update. By the way, I have the Exynos variant and there are no frame skipping in slow motion recording, I'm even using the not-so-fast Samsung Evo (not evo+) 32GB microSD.

Thats would explain a lots then as we only tested the edge in SD820 format ( client phone buyed in the US full price ) as we only have exynos version in Canada. Well if edge one do it whitout issue and normal S7 stutter then yeah its software issue mostly.
