Samsung is going to announce its next flagship smartphone, the Galaxy S IV, this Thursday.

This is a really big moment for Samsung. It has successfully transitioned from being some boring phone maker to one of the premier brands in the world.

The S IV could be its peak, or it could be the next step on the path to world domination. It all depends on how good the phone is.

Since you're probably curious about what Samsung has in store, we've summed up just about everything you need to know about the phone in this post. And watch the accompanying video for more analysis.

The screen is going to be really big

Samsung is planning to make the screen 5-inches. (Measured diagonally.) Its last flagship phone, the Galaxy S III was 4.8-inches measured diagonally. It doesn't sound like a big difference, but it is.

Is the screen going to be too big?

We can't answer this right now, but a 5-inch screen is really big. It's almost comical to make phone calls with a giant phone. But, Samsung sold a fair amount of the 5-inch Galaxy Note, so it thinks people want the bigger screen. Plus, we're mostly using our smartphones as computers so, bigger can be better.

It will be plastic with aluminum sides

A lot of people were hoping Samsung would splurge and use better materials for its new phone. According to various reports, the case will be plastic, which feels cheap compared to the iPhone or HTC's latest phone. Samsung is doing it because it's lighter, easier to make, and costs less.

It will probably be much boxier than the previous Galaxy phone

These leaked images of cases for the S IV suggest Samsung is going with a boxier look as compared to the S III.

Will it have a home button?

A leaked image of what the S IV is supposed to look like shows no home button for the phone. It's possible Samsung ditches the home button and makes the bottom part of the phone touch sensitive.

The screen is going to be LCD, not AMOLED, maybe ...

Samsung is the leading OLED display maker, but Samsung-focused blog Sam Mobile says its going with a LCD display for the S IV. Sam Mobile says it was struggling to make full HD AMOLED displays. However, Pocket Lint reported that it will have an AMOLED display. What's the difference? Samsung's AMOLED screen looks great, we're not sure what would happen with an LCD screen, but we assume it won't be bad.

It will probably be on all carriers

One the things that makes Samsung unique from other Android phone sellers is that it starts selling its phones on all carriers all at once in the U.S. We expect the same will happen with the S4.
