LG Optimus G (AT&T & Sprint) Review

LG Optimus G (AT&T & Sprint) Review
Starting with the Sprint version, its calling quality is a mixed bag. Even though its earpiece is strong and loud enough to make voices audible, there’s a bit of hollowness with voices. Unfortunately though, our callers mention having a hard time comprehending our voice on their end of the line, as it sounds rather muffled in tone. Switching to the speakerphone, its volume is good, but there’s a small amount of squeakiness heard at the highest volume. AT&T’s version fare better with its overall quality, since voices on both ends of the line are clear and distinct in tone – though, the same squeakiness persists with its speakerphone.

During our time using both devices, we didn’t experience any dramatic shifts in signal strength, nor any dropped calls in the greater Philadelphia area. Interestingly, the AT&T version maintains a signal strength of -73 dBm in high coverage areas – while the Sprint version is at the -95 dBm mark in medium coverage spots.


Carrying along a 2,100 mAh battery, it’s undeniable that it’s not as beefy as compared to some other offerings, but regardless of that, it’s able to provide us with an average battery life. Relying on HSPA+ connections with the AT&T version and old-school 3G EV-DO connections on the Sprint variant, we’re able to handsomely edge out a single day of normal usage on a fully charged battery. By the end of the day, we find it at the 30-percent mark. However, when it comes to 4G LTE connectivity, you can expect the results to diminish substantially. Even though we didn’t get a chance to try it out, the LG Optimus G also offers an Eco Mode that optimizes the CPU control to extend the battery life.


For the first time in a long time, it’s quite possible that LG’s fortunes might turn around for the better thanks to the LG Optimus G, especially when it’s packing that dreamy combination of a mighty quad-core processor and 4G LTE connectivity. To sweeten the pot even more, both AT&T and Sprint intend to sell this beauty for $199.99 with a 2-year contract – thus, presenting it as an admirable option for those looking to get a premier smartphone.

On paper, there’s a lot to like about this muscle-filled handset, as its performance is just excellent, but it’s missing out on being a balanced performer in all aspects to firmly woo us over. Sure, it’s one fast acting device and boasts one snazzy looking display, but it misses the mark in taking photos/video and call quality. And even though we appreciate LG’s efforts in enhancing its custom UI, which is easily its best offering to date, it doesn’t completely trump what its rivals have to offer. To tell you the truth, as much as we like to acknowledge the new features with the experience, we find a handful of them to not be as practical in actual every day usage.

For a moment, the LG Optimus G is going to be the strongest kid in town, with a quad-core CPU, 4G LTE connectivity, 2 GB of RAM and what not. However, as we all know, its exclusivity is going to be short lived, as there are already a handful of smartphones waiting in the bushes that’ll feature the same lovely hardware goodies – and possibly more! Gee golly Optimus G! LG surely has a viable competitor with this one, but it remains to be seen if it'll be strong enough to successfully compete with the top offerings by Samsung and HTC.

lg always comes out with the first of everything in mobile phone but always lose to samsung in the end. maybe they need to improve their marketing strategy instead of always trying to be the first in everything.

The reason is they just wait and see what other OEMs offer and then come up with a better specs with a tag "Being first"... They even conducted a survey here by comparing their new device with more than half year old S III and one X. They are always late in to the party... the problem is specs isn't everything. Its the whole user experience that we get with the phone... They should play their own game here after... Anyway great review as usual...

Let's review their accomplishments (at least for the U.S. market):
FIrst dual core phone.
First quad core phone.
First phone with a 720p display
First (to market) screen-dominated-design touchscreen phone(original Prada).
First with a 3D camera and display

What are they lagging in, exactly?

First does not mean good. The first dual-core G2x had a ton of hardware problems. The first 3D display was a gimmick that ahd no useful functions and the phone itself was big and heavy and mediocre. First 720p display was still running Gingerbread (or maybe even Froyo) and couldn't utilize it properly, and the other aspects of the phone were meh as well. These firsts are only ONE aspect of the phone, and if you fail at all the others, you might have an advantage in that one area, but the rest just drags you down to mediocrity.

first doesn't mean anything. look at iphone, the only first it had was the apple logo, but why is it selling well?

the real story is how LG executes it.
if LG messes up on marketting, or there are numerous bugs, glitches, crashes, none of the features would matter.

LG really, and finally, put everything they have into a product.
The result?
Best phone on Earth right now

Hope they used a different camera module on the Nexus cause it doesn't perform very well on the Optimus G

I will be very happy, when they use same camara module on nexus 4 cause camera was always weakness on nexus devices and this one isnt best but decent and that's still 3 time better than on last SG nexus.

at least we got the better performer 8 mp camera. for what it seems, that's the only department where the Nexus 4 will not be on par with the competition. perfectly fine by me.

The Nexus 4. 9.5/10

Probably a 9.5 if it's the same reviewer. I would dock the Optimus G down a full point just for the custom UI, but that's gone with the Nexus.

I knew LG won't be doing good even if they were working on a new camera sensor. I commented and everyone didn't agree...and here it is.
Well, at least 9 was expected but i don't know why, going through the review wasn't exciting at all. Blame it on the pre-release hype??

I know what you mean I expected a better camera at the least, everything else is great but they should have made an equal or better camera than Samsung if they wanna edge em out, specs are great but I expect issues with this product

I'm not quite understanding why the benchmarks are so different, if it's the same phone.

I'm not saying it is a bad phone. Hell, who am i to say the phone is crap? The specs are a kill!
I wrote negatively on the camera because in the past, there was an article about LG working on a new camera sensor for the G here in PA. If they were working on it, the result here is not worth what i read then.

why is it so hard to get a good QUAD core phone on t-mobile?

well I am going to give the Huawei Ascend D1 XL U9510E a try.

lets see how that works out!

$199.99 for a phone with spec like this sounds almost like a steal.
But sad reality is that LG products will never outsell Apple or Samsung.
