Some who just bought the new Samsung Galaxy S9+ and S9 are already posting about problems with their touchscreen, spots where there's no sensitivity — better known as dead zones because the phone can't tell what you want it to do.

People are posting on Reddit and on Samsung's own community boards that parts of their phone's screen aren't reacting to touch — from the top of the screen to the bottom. It's different for different people.

Owners are trying different fixes, including putting the phone back to factory reset and also increasing the phone's sensitivity, first noted by Android Police.

Samsung released both the Galaxy S9 and S9+ on March 16, last week. And during our review of the Galaxy S9+, we did not experience any of the touchscreen problems some users are noting today. In fact, we like the smartphone for its camera — particularly in low-light settings —and an updated fingerprint reader.

But often glitches only affect a small number of smartphones, and can depend on a variety of factors such as where specific parts are made, like the touchscreen, for example.

Whether this is a hardware or software issue is not yet known. Samsung, however, has encouraged users to get in touch with the company's customer services team to report the issue.
