Issue for the Samsung GalaxyS9+

Touchscreen Issue:

About a week after the release of the devices, users started experiencing an issue in the touchscreen, where it would fail to register input in any particular area of the screen, even after a factory reset. This was termed as "dead zones" by the users. Samsung has responded by issuing a statement that they were looking into a limited number of reports of Samsung Galaxy S9 and Samsung Galaxy S9+ touchscreen responsiveness issues.

Battery life issue:

Many users with the Exynos variant of the phone experienced super battery life. Analysts discovered that the four Samsung-designed cores had been poorly tuned, resulting in decreased battery life. This issue, however, has been addressed in part with the release of the August 2018 update.

Black crush issue:

Some users of the Samsung Galaxy S9 have reported the so-called "Black Crush" issues, where the display has issues displaying different shades of dark colors. Samsung has responded with a statement that they are aware of "a limited number of reports of Samsung Galaxy S9 and Samsung Galaxy  S9+ displaying dark colors differently than intended in certain instances" but has not provided an official fix for it yet.

Exynos 9810 performance:

In previous Samsung Galaxy S phones, the Exynos processor performed similar to the Snapdragon version. In the S9, the Exynos 9810 performed relatively slowlycompared to the Snapdragon 845. This was not very evident in synthetic benchmarks, but more so in benchmarks that simulated real world performance.
