‘S Lag’ a Complaint for International Galaxy S4 Owners With Exynos 5 Octa CPU

It looks like users of the international version of the Samsung Galaxy S4 that ships with the company’s powerful Exynos 5 Octa ARM processors are bemoaning the undocumented feature of the handset, mockingly referred to as ‘S Lag’ where the flagship phone would just stall. In early benchmarks, we’ve read that the Exynos 5 Octa is a speedy and efficient processor that’s powerful and bests the HTC One, a phone that ships with the same Snapdragon 600 processor made by rival Qualcomm that’s used by Samsung in the U.S. and U.K. editions of the Galaxy S4. Elsewhere in the world, though, Samsung is using the more powerful Exynos 5 Octa, which sounds good on paper and in theory.

However, it seems that early adopters of the Exynos 5 Octa-equipped Galaxy S4 are turning to forums and social media to complain about the ¬†processor’s lag when switching between tasks.¬†Phonedog‘s Aaron Baker has pointed this out in one of his video reviews of the phone when comparing the international and the U.S. versions, though Baker says it’s mostly not as bad as it sounds.

One Twitter user, Ramon Trotman, took to Twitter to complain about the lag.


“Samsung forgot to market it’s most prominent feature, S Lag,” Trotman says. “The feature that makes your 8 core 2 week old phone lag while doing nothing”

Considering the overall zippy performance of the Exynos processor, this news is really surprising given that benchmarks show that the Exynos beats out rivals.

When consumers in the U.S. and U.K. were concerned that they may have gotten the short end of the stick with the Snapdragon 600-equipped Galaxy S4 variants, Samsung head J.K. Shin told users that most people won’t notice the difference between the two CPUs and that in the end it doesn’t really matter. Shin defended his company’s decision saying that it was a supply issue, noting that the company couldn’t produce enough of its own Exynos 5 Octa chips for the global Galaxy S4 roll out, so it relied on Qualcomm in select regions to provide processing power.

Given outcries of lag–which can be noticeable when launching the camera or switching between apps–it looks like the U.S. and the U.K. lucked out with what appears to be a better experience right now.

Hopefully, a future software update will remedy the issue on the international Galaxy S4 and any lags or speed problems will get rectified.

This isn’t the first issue that’s plaguing the latest round flagship releases. We’ve recently discovered that there be an Antennagate issue with the rival HTC One.
