The technology put inside today's smartphones is becoming more and more advanced. Two excellent options are the Samsung Galaxy S6 and the LG G4, according to Extreme Tech.

Comparing the two smartphones, the first difference can be seen in screen size: The LG G4 offers a 5.5-inch screen while the Samsung Galaxy S6 is just a 5.1-inch display.

The displays are not created equally though. Samsung's Super AMOLED display provides a 2560 x 1440 resolution and 577 pixels per-inch (PPI). That display is the sharpest currently offered on any flagship smartphone. The LG G4 has the bigger 5.5-inch screen, but it is not an AMOLED display. Instead it uses an LCD display. This leads to 538 PPI and colors that are sometimes too cool. The AMOLED display looks better and displays higher quality images. 

The processor used in the LG G4 is the older Qualcomm Snapdragon 808. Since there were problems with the Snapdragon 810 overheating, LG decided to go with the Snapdragon 808, which is six cores instead of eight. Samsung decided to go away from Qualcomm all together and create their own eight-core Exynos 7420 processor. The Galaxy S6 processor might work a little faster on heavy workloads, but just like the Snapdragon 810, it can get quite hot as well. The LG G4's Snapdragon 808 stays much cooler when it has a heavy workload, and its performance is not that much less than the Galaxy S6.

Both phones will start off with 32 GB of storage and 3 GB of RAM. Samsung wants customers who want more storage to buy a phone with more storage space, thus spending more money. LG offers a much better value by featuring a microSD slot that allows for more storage space to be added.

LG already had a great camera in the LG G3, but the LG G4 is its best camera yet. With the f/1.8 aperture lens, LG's pictures taken in low light turn out great. Samsung's Galaxy S6 produces excellent HDR images, but the LG G4 wins with its wide aperture lens and laser autofocus system.

It's a close call when it comes to these two smartphones. With the microSD capabilities, the LG G4 is the better value. The Samsung Galaxy S6 does offer the more powerful processor, but as storage space goes up, the price does as well, leading to a very expensive smartphone.
