(I originally posted this on reddit here: My experiences using both a Nexus 4 and an LG Optimus G but wanted to hear everyone's thoughts here too)
I recently used both a Nexus 4 (in a T-Mobile store) and an LG Optimus G (in a Sprint store) within 20 minutes of each other and here's my experiences:
(I used the Nexus 4 first, the LG Optimus G second)
Nexus 4
After reading the reviews I was surprised (and disappointed) to discover there was a fair amount of lag. It was the usual "Android" lag:
- Pinch to zoom in a browser had lag
- Scrolling in Chrome had some lag
- Popping up multi-tasking overlay had lag
- About 20% of the time going back to home screen had some lag
- Taking a picture in the camera app had lag
- Getting the camera controls to popup (and then moving your finger to select one) had lag before they turned blue
None of the lag was showstopping but it did not feel like a next-generation phone as the reviews had indicated. It felt like a Galaxy S3 with ICS.
Photosphere was amazing. Even indoors (in the T-Mobile store) it was able to stitch the image seamlessly (I followed people's suggestions to rotate around the camera lens).
The phone looks amazing and is surprisingly thin (thinner than it looks in the reviews). It feels good in your hand.
In a speedtest (I ran it 4 times) I got between 1.7-2.1mbps down and 1.5-2.2 up, but that's T-Mobile not the phone. (The store claimed they had HSPA+ 42)
LG Optimus G
The fastest phone I have ever used. I was very surprised. I'm including the iPhone 5 in that assessment. There was ZERO lag in anything I did on the phone. Switching home screens, bringing up the app drawer, starting the camera, pinch-to-zoom. NOTHING could stop this phone.
Unfortunately, it's a huge, blocky phone that, while light, doesn't feel comfortable in your hand like the Nexus 4. It felt thinner than the Nexus 4 though I'm not sure if it really was.
Speedtests gave me 700K-1.4mbps down, 650K-900K up. (Sprint claimed there was LTE in the area but only if I took it outside the store)
Camera was not very good. For a phone that has a 13 megapixel camera, I couldn't figure out why the pictures were no better than on the Nexus 4's 8-megpixel. Very disappointing. And the reviews were right that the auto-focus just kept sputtering.
But that speed! I have only used one phone in my life that came close - the iPhone 5. While I'm not a fan of LG's theme on Android (I prefer stock), this phone ran like a next generation phone. I'm still in shock at how fast it was...and confused. Since the Nexus 4 comes from the same hardware and is a combined effort between Google and LG, and is Google's flagship phone, why is the Nexus 4 drastically slower?
Please write with your experiences with these two phones as well, I want to know if these were isolated results.
