[G2 Q&A, Help & Troubleshooting] XxZombiePikachu:
you bought your question to the right place so first the lag:

-it honestly depends on how much stuff you put on your phone and the kind of use I have had my device totally stock for about a month now and have not experienced any lag, before that I was on a custom rom for about a week 0 lag and before that I had gone to complete stock in late February to get on kk and for those months 0 lag I have had my g2 since last year late October(switching roms on a monthly basis October was stock/November was aeonflex 4.2/December was aosp I test drove different aosp roms every couple of days/January back to aeonflex 4.2) and have never had any lag issues

-if you root you can install custom kernels with features like touch boost which makes the cpu jump to a higher ghz for clean smooth, scrolling/etc

-gaming on my g2 has been pretty good so far since I don't switch roms all that much I can keep my games and data no problem and the g2 does very good on stock:

-Emulators

--Dolphin(mainly for gamecube games) this is the most demanding emulator in existence it demands a lot of cpu power and I can manage for a good hour any more than that is overkill on pretty much any current device and some device can't go more than 30 minutes

--Daedalus(N64 emulator) play it for a couple of hours full speed no problems

GBA/GBC/ETC any of those non demanding emulator can be played for hours, I don't have any ps1 games in my collection which is the reason I have yet to get the ps1 emulator but I am sure it handles that too

-Games

--GTA Liberty City/Vice City/San Andreas not an issue can play for atleast too hours without issues on low brightness of ocurse

--Need for speed currently I started playing the most wanted and have not gone more than an hour

--Dead Space the game has a high brightness which cannot be changed(playing with phone brightness at 0 and the it looks like you have full brightness) no more than an hour because of the brightness phone heats up pretty quickly

--Dungeon Hunter 4 back in January I played this game all the time and have to say you could go for a couple of hours with small 10-15 minute breaks in between and didn't suffer any issues

right now I have about 50-65 apps and I don't ever reach the 100 apps point(debloated of course) but my phone is always low on memory because of the gamecube games I carry around(about 1.5gb each) and I have zero lag on my device if want any other details maybe on a specific game(free of course) just let me know

edit: the dolphin emulator is the most demanding app I can think of in existence, currently there isn't a single cpu out there that can play every gamecube game at 100% let alone wii games(we are hoping this changes with intels new cpu the devils canyon XD) which is the reason I always include it when reviewing gaming on the g2, I am a huge PC gamer/Console gamer from old school to new school(except the xbox one/ps4 since they are not in my budget currently) and I know when a device is good for gaming since this is one of the priorities I have when looking for a phone, if you are interested in a gaming tablet than Q3/Q4 this year is a good one thanks to Nvidia Tegra K1
