Samsung Game Optimization Service

A new frequently asked question about Samsung Korea has provided a comprehensive answer regarding CIS. The company also clarified the rationale for having a 10,000 apps list. It also offered a disappointing explanation for the exclusion of benchmark apps from CIS.

Samsung made tech headlines for all the wrong reasons last week when it emerged that the company was throttling games through its Game Optimizing Service (GOS), but not slowing down benchmark apps. In addition, a list of 10,000 apps appeared online that were apparently restricted, most of which weren’t games to begin with.

Now Samsung has published an FAQ about the CIS saga on its Korean support website. In the machine-translated FAQ, the manufacturer reiterates that GOS “optimizes” CPU and GPU performance to avoid excessive heat.

It also reiterates that a software update is coming for the Game Launcher that will bring a performance priority to the Game Booster settings suite, stating that users can expect ~10 frames per second improvement in at least one game.

Interestingly, Samsung claimed that a list of 10,000 apps that surfaced online was not really a list of apps restricted by CIS. Instead, it claimed the list was “to quickly determine whether a newly installed app is a game or not.”

Samsung GOS and benchmark apps

A disappointing turn of events was the fact that benchmark apps weren’t subject to the same restrictive measures, but the company clarified its stance here:

The benchmark tool is not a gaming app and thus does not fall under CIS.

That’s not exactly good reasoning, as benchmark results are often used to measure smartphone performance. So these benchmarks wouldn’t really reflect the real performance experience.

It’s worth noting that OnePlus received a similar level of flak for the OnePlus 9 Pro after it was found to be limiting apps but also cutting out many benchmark apps. In fact, a poll by the Android Authority at the time found that nearly three-quarters of respondents would not buy a phone that would reduce performance for better battery life.

Bypassing CIS and Warranties

Samsung also confirmed that it started blocking CIS bypass in One UI 4.0 last year and stuck with One UI 4.1 last month. The company noted in the FAQ that it is now considering removing these measures so that users can more easily disable GOS again.

In addition, the company also tried to allay concerns that it wouldn’t offer free repairs due to overheating when people used the upcoming performance priority option. It noted that free service would still be offered if the phone was within its warranty period.

Finally, Samsung said other Galaxy phones with CIS (apart from the S22 series) would also receive updated optimization software. Presumably, this means that these phones will also be given a performance priority in the Game Booster.
