I've used all LG flagship phones since the LG G2. The LG G2 was one of the only phones that had very small bezels and a big battery at the time of its release. LG, however, failed to keep the momentum with the LG G3 and G4. After their failed attempt at creating a modular phone, LG decided to go back to basics with the LG G6. In my opinion, this is one of the better decisions the company has made in recent memory.
LG deserves major props for the simple and elegant design of the LG G6. The phone looks and feels premium, something the LG G5 failed at. Also, I love that LG did not taper the edges as it made the LG G6 very easy to hold. I used the phone without a case (as I do with all of my phones) for a month I didn't feel like the phone was going to slip out of my hands.
Also, the tiny bezels make it usable with one hand, making it the only other device besides the S8 with a screen this big!
LG is only of the few Android manufacturers that offer a dual camera setup and I must admit that the addition of the wide angle is super nice. There were a lot of times where the wide angle lens helped me get the shot I wanted. The primary camera felt identical to the camera on the G5 and V20. It's not the fastest and it definitely does not produce the best images, but it gets the job done and produces above average results. However, just having the two cameras makes it one of the best phones to have if you're into photography. Also, the software is pretty good! LG is one of the few manufacturers that offer manual video controls.
I like that the front camera is wide as well, something I think all companies should do. By default, it is set to crop mode so I'd strongly suggest changing it to wide to get the best result.
I love the screen on the LG G6. While it is not as good as the latest AMOLED panel on the Samsung Galaxy S8, it is easily in the top 3. The colours are vibrant, text looks amazing, and it has very deep blacks for an IPS display.
I like that LG didn't ditch the headphone jack like HTC, Motorola, and Apple. The phone produces good sound even though LG does not offer the hi-fi DAC in North America.
I also like that LG offers expandable storage. I usually don't like inserting microSD cards, but it is nice to know that I can store more data in my phone if I need it.
Other things I like that don't really deserve further explanation are wireless charging, quick charge 3.0, and always on display.
After using the Google Pixel, which has the same processor as the LG G6, I was pretty confident that performance was not going to be an issue. However, LG did not optimize the LG G6 as well as Google did. The performance of the LG G6 left a lot to be desired. While the phone is not terribly slow, it does lag while performing usual tasks.
In LG's defence, I switched to this phone after using the iPhone 7 Plus for some weeks, which is a beast when it comes to performance. So, I might be overly critical as it seemed super slow compared to the iPhone.
LG has never been great at image processing and the trend continues with the LG G6. Images are very obviously oversatured and oversharpened by the image processor. While it works in some conditions, it looks really bad while shooting landscapes. The sky looks too blue and and objects look oversharpened.
While the battery life isn't bad, it leaves a lot to be desired. The G6 lasted a while if I constantly used the phone, but it barely lasted a full day with mixed use. Most days, I ended with about 15%, which isn't so great. Quickcharge is great to have, but it shouldn't be a reason to put smaller batteries in phones.
The G6 is one of the best "small" phones LG has made since the G2. The phone gets a lot of things right. It looks and feels great, the dual camera setup is amazing, and the display is beautiful to look at. However, the subpar performance, overdone image processing, and battery life prevent this phone from being the best device in the market right now.
I'm glad LG priced the G6 right which lets the phone carve a niche in a saturated industry. If you can't afford the Galaxy S8 and are looking for a phone with an amazing design and display, decent performance, and a headphone jack, look no further. You'll be very happy with the G6.
