OnePlus backtracks on the "Jelly effect" again. (Update: not really)

UPDATE: OnePlus has reached out to us to clarify that the statement in the tweet was not official. The tweet has since been removed to avoid confusion.

One of the few controversies that have emerged around the time users began to receive their OnePlus 5 devices is the so-called "jelly effect". Long story short — when you scroll up and down on some pages, such as your settings or a website in Chrome or whatever else, the display doesn't look like it refreshes evenly and the animation "wobbles" instead of scrolling smoothly and consistently.

Is it a big issue? That's certainly debatable. But it can sure get a bit confusing if you try to follow OnePlus' response on the matter. First, it was looking into the problem, then it claimed that the issue is only reported by a small number of users, is natural and not a concern. Hours after that, the company tweeted out that it'll be fixing the "jelly effect" via a future software update. Now, that last one raised some eyebrows, since it's theorized that the problem is caused by a hardware design mishap — the fact that the display panel is, apparently, installed upside down in order to make internal components fit.

We're not sure how plausible that theory is, seeing as not all OnePlus 5 have the issue. However, we're also not sure if it's fixable via a software update since the company has now deleted the tweet that said it's working on a fix and has, yet again, backtracked to calling it a natural phenomenon. The latest tweet from OnePlus support goes like this:

Yes, "persistence of vision" is a thing — it's the phenomenon which lets you see a light trail after a swinging lightbulb in a dark area. It's also the culprit behind why the "rubber pencil trick" is a thing — wiggling a pen between your fingers and observing it at the right angle makes it look like it's bending when in reality, it isn't. Basically, the stream from your eyes to your brain comes with a tiny delay, which causes all of these phenomena to occur.

On to OnePlus' latest explanation — we have a couple of gripes here. First, if it was caused purely by Persistence of vision, the "Jelly effect" wouldn't be observable on a slow-motion video. Second, by that logic, we should see the "Jelly effect" on every smartphone, not just some OnePlus 5 units.

Considering that the OnePlus 5 is a pretty solid phone for a very good price, we would say that a display being a bit wonky (only) when you are scrolling up or down on it is not really a huge deal. But how that issue is handled is a bit... baffling?

I'm sure OnePlus will address it in a future upgrade, but it really isn't an issue unless you are really OCD. Only thing that would make it an issue is if the distortion remains when you are not scrolling. If the page looks normal when static (not scrolling), no big deal.

So, basically, it's the user's fault, sais One Plus. Well, it's indeed the user's fault for buying Chinese crap from a company that mounted the display upside down just because they tried to copy the iPhone. How stupid is this, really ?

OnePlus claiming that jelly scrolling is "normal" when the screen is intentionally installed inverted is like Zeiss Optics claiming micropsia is normal when they invert the ocular and the objective lenses in binoculars.

Now, I'm certainly not THAT tech savvy but isn't it an easy fix...? Just re-calibrate the gyroscope and make the phone 'think' that it's upside down while it's actually 'downside up'...? Am I missing something...? Oh well, eh? G'Day!™

Fraud company, cheating on benchmarks, falsely calling their products flagship killer and terrible marketing schemes. Just die already OP.

I think OnePlus is setting itself up for it's worst year if it continues down this path of errors and missteps. I wouldn't be surprised if this is their worst sales year after this debacle. A good company should admit the error and learn from it (i.e. Samsung after the battery situation, Blackberry Mobile after the screen adhesive problem, etc.)

The fix is easy: release a firmware update that turns the image upside down, and always use the phone upside down, and thus the display will be correctly positioned :))

"and always use the phone upside down" that way, the home button will be above the screen *genius*

I'm wondering...if it were "normal" as they claim, would we not notice the effect far more often with other phones? Has that been the case?

I've learned to completely ignore OnePlus phones released in odd years. Every year after a success with them, they f**k up.

Manufacturing mistakes happen. They suck, and companies should do everything to avoid them, but sometimes it happens. It's all about how a company handles the situation after the fact that really matters. Definitely not a direct comparison, but look at how Samsung handled the Note 7 issue. They fumbled along the way, but they did take ownership and accountability of it at the end of the day. And this is coming from somebody who's no huge Samsung fan. They did their best to do right by their customers (for the most part). This confusing mess of communication from OnePlus is just bad. They need to own this and not try to continually pass the buck along. It's not even the issue itself that turns me off to their product, it's how they communicate with and treat their customers that ensure that I will stay away from the OnePlus 5.

It's been that way with Oppo/OnePlus since the beginning. Remember the yellow stain issue with the first few batches of OnePlus One's? They first said it was because they set the color temperature of the screen to a warmer color, thus the yellow tint. Then several sites did a little digging, checked the color temperature, changed it to a more blue tint and the yellow showed up on either the top or the bottom of the display mostly. Then, people started trying to figure out what it was. It was discovered that the supplier of the screens didn't let them cure properly, in Oppo's attempt to move product, and the glue hadn't cured between the display, and the glass. I had the issue on the bottom of my screen, fixed it via using exposure to direct sunlight & using a UV light. Oppo, well, Peter of OnePlus finally admitted that "some" user may of had the issue. OnePlus also said the OnePlus One would have stereo speakers, but, it had twin mono speakers, among a ton of software bug fixes. OnePlus 2 suffered a bunch of problems, from the overheating 810 chip, to no NFC, to a usb port that was claimed to be a usb C port, but was a usb C CONNECTOR. This "never settle" company settles way too much. Their customer service is next to zero. Hey, if you can get one after they've been bug fixed, say a couple months after release they aren't a "bad" phone, but, their #1 thing about getting a higher end phone for a cheap price is out the window since they broke the $500 dollar mark with the 5. Granted it's cheaper than say an iPhone/Galaxy, but, there are many sub 500 dollar phones these days, that perform just as well, without the untruth/distortions from Oppo/OnePlus.

I was hoping OnePlus would say "You're scrolling it wrong!" Disappointed with their flip-flopping...

OP justification is funny at times. They seem imature regarding such an issue ! I am keeping an eye on both of my OP5 units just in case I notice the Jelly effect ..... blob.blob.blob

What's wrong with jelly scrolling? I thought it was considered cool when the stuff on your screen bounced, squished and stretched back in the day. /s

The slow motion video observation is a red herring. A digital video can make the effect appear in the video even when it wasn't actually there. For examples of that sort of thing, look at videos of spinning propellers. Digital displays (and digital imaging devices in cameras), are scanned, usually left to right and then top to bottom. If the frame to be displayed or captured changes over time during a single scan, the portions that are refreshed later will show/capture a later state of the changing image and the entire image will not be time-consistent with itself. In this case, because the OP5 display panel is upside down, it gets refreshed in the opposite direction (bottom to top, probably). With the digital camera scanning in one direction while the OP5 display refreshes in the opposite direction, the time-inconsistency of the resulting video is doubled. Turn the camera upside down and take the same video again, and you'll see a very different effect. All displays that scan to refresh exhibit this jelly effect (unless they have software that intentionally distorts the animations to counteract the refresh effect). Our eyes are accustomed to this effect when the scanning happens in the "normal" direction (top to bottom). But when the scanning happens in the opposite direction, we notice it. To prove this to myself, I turned my Galaxy Note 3 upside down, and it exhibited a noticeable jelly effect on scrolling animations. (It's running Lineage OS and I enabled 180 degree rotation.) Right side up, I couldn't see a jelly effect.
