Wondering what you can expect from the Samsung Galaxy S4 come 2013? While Samsung has yet to officially announce the device, given the success of the Galaxy S, Galaxy S2 and the Galaxy S3, it’s safe to assume that a Galaxy S4 is in the works, and if the rumors are to be believed, it seems like the Galaxy S4 will ship with an unbreakable screen! This is probably good news to those who drop their phone often, or who are looking for durable devices. This unbreakable display is apparently thanks to Samsung’s use of OLED, where OLED panels are said to be able to replace glass substrates with plastic, and because of that many analysts believe that unbreakable plastic substrate displays are in the works and could debut with the Galaxy S4, or maybe even the Galaxy S5. A few days ago we reported that Samsung’s flexible displays are set to ship in 2013, so perhaps it might be even be related to that. Either way we won’t read too much into this and suggest you do the same, but what do you guys think?
