my first android phone, best bang for the buck
this is my first android, and I love it, despite the software issues with Stock LG firmware, whether ICS or JB. P.S. my baseband is v20c (UAE).
Quick note, which may cost you seconds of your time and perhaps solve all your issues before jumping to other, custom ROMs. Have you disabled MLT from the hidden menu? (many users reported that it solves the lags)
Open Dialer -> Dial: 3845#*880# -> MLT (all the way at the bottom of the list) -> disable
I tried it on JB (4.1.2) and it definitely helped with the lags.
But then few days later, I decided I wanna play with Kitkat 4.4.4, and I went for the most customization-rich ROM: Beanstalk
, and also added the stock LG camera app from JB
. Why? because it is faster and the focus is a little better I think. The only thing that doesn't work in it is that if you switch to front-facing camera, it is just a full green screen. However, the camera app that comes in beanstalk doesn't have this problem with front-facing camera. And, you get to have both camera apps installed, so you can switch and compare quality.
The only trick to get the last build of Beanstalk (4.4.4007 , 14/07/14) booting was to also flash iodak v10 kernel immediately after the BS ROM. Then of course gapps (google apps).
Only issue or bug I noticed is you get an error message about DSP manager crashing when playing music, but the music plays afterwards. This is a known issue and should be fixed in later releases.
Alternatively, if you prefer simplicity over customizations, and rock solid stability over latest/bleeding-edge releases, you could go with the stable version of CyanogenMod 10.1.3
Hope I helped.
