As the Samsung Galaxy S8 nears its launch, those who already have a Samsung Galaxy S7 would wonder if it would be a good idea to upgrade to the upcoming model. Samsung did a good job with the Samsung Galaxy S7, but the opposite is true for the Galaxy Note 7. A Samsung Galaxy S8 vs S7 comparison is needed for those that have the latter.

One big difference between Samsung Galaxy S8 and S7 is the new voice assistant, 'Bixby' according to Forbes. It is going to be interesting to see how Google reacts now that Samsung decided to have its new flagship phone have a voice assistant.

In a Samsung Galaxy S8 vs S7 comparison, the camera remains to be the deciding factor. According to Recombu, the Galaxy S7's is still one of the best smartphone cameras in the market today and tech fans are expecting a huge leap from the Galaxy S8. Rumors point to the S8 having a dual-lens back camera but it is still not a sure if it will work together or separately.

As for the battery life in the Samsung Galaxy S8 vs S7 battle, it is no secret that the S7 is one of the slowest 2016 flagship phones when it comes to battery recharging because Samsung's 'Adaptive Fast Charging' has not been impressive. Other phones like the OnePlus 3 can be charged much faster so fans hope this is one area Samsung focuses on in the Galaxy S8.

For the screen in the Samsung Galaxy S8 vs S7 comparison, the S7 has a stunning 5.1-inch Quad HD Screen. It is expected the Galaxy S8 will sport something similar despite talks of a 4K panel being introduced by Samsung.
