G Flex vs G Flex 2

The original G Flex was ahead of its time when it launched in 2014. The huge smartphone has a screen curved from top to bottom, hugging your face when on a call. Various things made it a failure, but LG is having a second crack with the appropriately named G Flex 2 (above, right). Here's how the G Flex 2 compares to the original.

We've based this comparison on our G Flex review, and our hands-on time with the G Flex 2. And here's what we know about the G Flex 2's price and launch date

LG G Flex vs LG G Flex 2: design and screen

The new G Flex 2 has a smaller 5.5in screen with a higher 1920x1080 resolution. This is arguably a better decision than the 6in, 1280x720 of the original. It gives a pixel density of 403ppi - essentially the same as the iPhone 6 Plus.

The new smartphone uses the same POLED display technology as the original, but we've not had enough hands-on time to come to a conclusion about whether LG has solved the image retention issues we saw on the G Flex.

As for the curve, it has the same 700mm radius, but in LG's words, the G Flex 2 "harmoniously incorporates a symphony of curves ranging from a radius of 400mm to 700mm across the front, back, sides and top-to-bottom edges. The dynamically curved layers deliver a sleeker and more dynamic look to G Flex 2".

Here are the two phones, side on, with the G Flex 2 on the right.

G Flex vs G Flex 2

Here's how the two phones compare in terms of size and weight:

G Flex: 160.5 mm x 81.6 mm x 7.9-8.7 mm, 177g

G Flex 2: 149.1 x 75.3 x 7.1-9.4 mm, 152g

In terms of design, the G Flex 2 retains the rear-mounted 'control deck' so beloved of LG. The G Flex 2 looks a lot like the LG G3 from the back, and both the G Flex and G Flex 2 have a single rear-mounted speaker.

LG G Flex vs LG G Flex 2: self-healing back cover

One area where the G Flex was ahead of the competition was the self-healing coating on the back cover. This is improved on the G Flex 2 and minor scratches disappear in seconds rather than minutes. It's quite a sight to see this in action, which we did at CES 2015.

For those who prefer not to hide their smartphone in a case it's great news, and with the glossy grey and red colour options you'll probably want to show them off.

LG G Flex vs LG G Flex 2: hardware

Another highlight of the G Flex 2 is the Snapdragon 810 processor, making it the first officially announced smartphone to feature Qualcomm's new 64-bit chip. (Here we explain the difference between 32-bit and 64-bit chips). Depending on country, the phone will have either 2 or 3GB of RAM (2GB in the UK), and 16 or 32GB of internal storage.  

There's also a microSD card slot which LG's UK website states supports up to 128GB of storage.

By contrast, the original G Flex had no card slot - storage was limited to the 32GB of on-board memory.

Both phones have 802.11ac Wi-Fi, NFC, GPS and IR blasters, but although the rear cover is removable, neither phone allows you to remove the battery. Interestingly, LG has dropped the capacity to 3000mAh for the G Flex 2, but we haven't yet had time to test battery life: improvements in processor power consumption may mean the new model lasts longer than the old.

Thanks to the new chipset, the G Flex 2 supports fast charging, and is said to charge from empty to 50 percent in 40 minutes.

LG G Flex vs LG G Flex 2: cameras

The on-paper specs show that the two phones have the same megapixels front and rear, but the G Flex 2 gets the G3's 13Mp camera complete with laser autofocus and optical image stabilisation. The G3 takes great photos and video, so although we've not yet tested out the G Flex 2, it's bound to offer the same quality.

The rear camera also has the G3's dual-tone LED flash, which helps to make skin tones look more natural in low light.

G Flex vs G Flex 2

As you'd expect from a brand new Android phone, the G Flex 2 ships with Lollipop, and LG adds its own tweaks to the interface. One of the most useful is the ability to swipe down from the top of the screen when the phone is off to check the time and notifications, which LG calls Glance View.

Of course, G Flex 2 owners will also benefit from Lollipop's other new features including user profiles, a dedicated battery saver mode and more. Read our full Android Lollipop review for more details.
