With the announcement of the LG G Flex 2 at the LG Press Conference, we finally saw the launch of a device with Qualcomm’s Snapdragon 810 SoC. While the SoC is one notable improvement from the previous G Flex, we see a great deal of improvement in almost all areas. One of the most immediate improvements is the new OLED display when compared against the previous G Flex. There are a great deal of other improvements, which can be seen in the spec sheet below.

As one can see, while there are a lot of elements shared with the LG G3, there are a number of areas where we see notable improvements that differentiate the G Flex 2 from the G3. The size of the phone has also decreased, as LG claims that people didn’t like the sheer size of the previous LG G Flex.

LG has also changed the design of the G Flex 2 to be more similar to the LG G3 with its brushed metal finish, although the self-healing polymer dictated a glossy finish with a brushed design beneath the finish. The self-healing polymer itself has been notably improved, healing over seconds instead of minutes like the original LG G Flex. LG has also introduced Dura-Guard glass, which is said to improve drop resistance when compared to Corning Gorilla Glass.

In practice, this combines to make the LG G Flex 2 into a rather interesting phone. Unfortunately, it seems that all of the phones available for demonstration were running non-final software. This meant that it wasn’t possible for us to properly benchmark the device, and there seemed to be more lag in the UI than the LG G3 or Nexus 5. In addition, these demo phones were running in poor conditions for benchmarks, as maximum brightness was constantly reduced due to thermal throttling.

Despite these issues, the G Flex 2 was still an interesting device to try. While I haven’t used the original LG G Flex extensively, I noticed that the 1080p display on the G Flex 2 behaved differently from the 1080p display on the Galaxy S5. Although the G Flex 2 doesn’t have the odd ghosting effects present on the Galaxy S5, the G Flex 2 does have noticeable mura or some sort of texture to the display. Given the demo conditions, it’s difficult to discern whether or not the display is RGB stripe or some form of PenTile.

Outside of the display, the UI brought our first experiences with LG’s UI when layered on top of Android 5.0. Unfortunately, the UI seems to be quite similar to the G3’s UI on Android 4.4, even though there are noticeable changes in areas like the notification drawer and multitasking menu. It may be that we will be left waiting until the LG G4 to see a redesign of the UI to fit with the new design guidelines. At any rate, the camera remains identical to the LG G3, with the same Sony IMX135 sensor, optics, laser AF, and OIS+. The UI remains largely similar here as well, and it seems that there remains a noticeable amount of shutter lag similar to the LG G3. On the bright side, the G Flex 2’s camera remains quick to focus and the OIS is incredibly stable when compared to most solutions I’ve tried. Overall, despite some issues the LG G Flex 2 seems to be a promising device.

    So the modem is discrete ? Usually you specify when it's integrated and not even sure anymore how they call the modem in SD810, used to be 9x35 but ,maybe they upgraded the name.
  • Penti - Friday, January 9, 2015 - link

    The modem/baseband is integrated just as the name suggests. It lists MSM8994, and I also don't know of an 810 SoC without modem. MSM means Mobile Station Modem, their model name for pure application processors is APQ, like the 805 is. https://www.qualcomm.com/products/snapdragon/proce...

    The modem is integrated as denoted by the MSM designation in the SoC. The 9x45 reference is the IP block in the SoC.
  • richworks - Friday, January 9, 2015 - link

    The 9x45 is the RF transceiver chip which is independent of the SoC
  • JoshHo - Friday, January 9, 2015 - link

    The referenced modem is not a transceiver. The transceiver is most likely the WTR3925.

    Thanks, you always mention when listing the connectivity that it's iP block (when it is), this time you didn't and the integrated modem in the SD810 used to be called MDM9x35 so that was confusing.
    I thought maybe they are not using the integrated one for so odd reason.
  • Penti - Saturday, January 10, 2015 - link

    The discrete version i.e. MDM9x35 doesn't support 3x20MHz carrier aggregation. MDM9x45 is pretty recently announced and is a Cat 10 device. So the IP-block that makes up the modem is somewhere between those two products.

    - MDM9x45 is Qualcomm's 5th generation discrete baseband processor. It's Cat 10 since it supports Carrier Aggregation on the Uplink as well.

    -Snapdragon 810 integrated IP Stack is basically MDM9x45, minus that Carrier Aggregation on the Uplink which makes it Category 9.

    They're both capable of aggregating up to three 20MHz Component Carriers on the Downlink for the maximum aggregate capacity of 450Mbps.

    You are thinking of the 801/805. 810 is and always has been 9x45
  • SydneyBlue120d - Friday, January 9, 2015 - link

    So the Snapdragon 810 issues are all true?
