I still can't understand how this phone is so far under the radar. Granted I haven't used one so I don't know first hand but every review I've seen has given it a great review yet if you don't follow forums you wouldn't even know the phone existed. I'm really excited to get my hands on it. Did you use custom roms or stock? Also how does it compare to the S3 and Note 2 in terms of speed, battery life, software features, and stability? Those are my most recent Android phones.
Yeah, it amazes me that it's been such an underrated phone, because I found it to be a beast.
I used the stock ROM (in conjunction with Nova Prime) and just rooted it so I could install some apps that need it (Titanium Backup, adblockers, etc.). As far as speed goes, it's probably the fastest phone I've ever used...fluid, no stutters at all, things just happen instantly. It's MUCH quicker than my S3 was and even a little faster than my Note 2. Battery life, for me anyway, was the really big (pleasant) surprise. I found that it got REALLY good battery life. I usually keep the brightness around 50% and the screen on the OG is the brightest screen I've ever seen. Seriously, at 100% it's insanely bright. I was getting, on average, 4.5-5 hours of screen-on time, which is what I was getting on my rooted stock S3. It's hard to compare it to the Note 2 since the Note has such a huge battery, but I'd say in terms of screen-on time to battery size, it's on par.
One thing I've heard people say is how LG did a nice job with the software and I would agree with that. It's fairly close to stock JB, with just a few tweaks here and there. One of the really nice things you can do right out of the box is the notification toggles...you can actually reorder them and change which ones show up there. I love my Samsung phones, but why they don't implement this, I have no idea. It's a little tricky to find at first, but simply drop down your notification window and slide the icons all the way to the right. Then you'll see an "Edit" button...tap this and you can then change them up. Pretty nice!
Stability-wise I had no problems at all. When I first upgraded it to JB from ICS, I had a couple of weird reboots or freezes, but after JB settled in, I never had another issue. This was in the first couple of days, but like I said, after that, it was flawless.
I really think you'll enjoy it. The size is perfect and the fact that it has LTE and SD card support is a great plus.
*edit* I forgot to add this. I was so impressed by the OG that I'm currently sitting on my upgrade with AT&T to see what the OG2 has to offer. Rumors are, it's going to be a massive phone spec-wise (5.2" screen, Snapdragon 800, 1.9ghz, 13mp camera). It might be out by August, so I'm just going to wait and see, but if it's anything like the OG, I'll probably get it.
BTW, the camera isn't as bad as people make it out to be. While it's not as great as the Note 2 or S3 camera, it does take nice pictures.
