I have a couple of Optimus G Pro Questions
1. Is the device too large to put in your front pocket? Please be honest....
Depends on your pockets, but I'd have to say, in general, "no". At least not in jeans pockets if you plan on sitting down. This is an unapologetically large phone. The bezel is all but nonexistent, but the screen is frikkin' huge, and "you canna change the laws of physics, Captain!"
While thin, it's still a 3-inch-by-6-inch phone. I use an old neoprene pouch holster that I used to carry my PalmPilot 3 around in, and even it is too small for the velcro closure to hold, so I have a rubber band around it to hold it shut. Redneck chic.
2. How has LG's update history been. Do you honesty think this device will get 4.2? or even 5.0 (KLP)?
It's possible we will, but I'd call it somewhat unlikely, particularly on the carrier version. Look how long it's been since the Value Pack came out, and AT&T is just now releasing that. Even if LG releases 4.2 or some Key Lime Goodies, it may never reach carriers. It's a very functional phone all the same, and I never plan on a non-Nexus phone getting a major update.
3. Has anyone...found a way to get the qslide or the brightness bar...from the notification bar?
Yes, apparently with root this is possible. I don't root. But I have come to love qslide and particularly the ease of brightness adjustment. Your mileage, opinion, and willingness to root may vary.
