[AT&T LG Optimus G] blitz9826:
5.1.1 CM12.1 Unofficial, Watchdog Kenel Panics (green screens)

long post, so if you want the meat of the story scroll down!

hi guys, i'm an avid user of the e970 and i found this marvelous forum to be one of the most useful resources ever. freegee, lgnpst for when i bricked my phone, cm11, cm12, solid geeb kernel, validus, and now cm12.1 unofficial; it's all there. i'm certainly enjoying the experience that this device paired with this community has to offer.

first i'd like to thank the developers, and i'm seriously appreciating the active development on 12.1. i just finished using validus and while it was a much more solid experience than the short-lived cm12, android 5.0 was still killing me in terms of battery life. 5.1 certainly fixed that up though.

i want to second a few observations that are being made, which are the green-screen happenings. i want to mention something in particular though:

when i first flashed 12.1 unofficial i didn't have the recommended gapps at the time, so i flashed the minimal gapps for 5.0 (just to get wheels rolling per se). sure enough, it was a crazy experience. com.google.<insert service name here> was crashing repeatedly, often causing loss of functionality or green-screens. in a day i'd get anywhere between 4 and 7 green-screens (this was for three days, i'm talking about the 4/21 release). i re-wiped and formatted /system and re-installed 4/21 cm12.1, along with the recommended gapps this time.

NOW i'm having far fewer crashes, far fewer slow-downs and stutters; overall a much more lean experience. i also want to especially thank the developer for one thing: THANK YOU, for giving me back HSPA+ speeds on my att jb radio. validus and cm12 for some reason wouldn't give me HSPA speeds, just slow HSPA speeds that would take forever to peak at 200, 250 K/s (averaging around 70 to 140 K/s). now i can enjoy speeds up to 900 K/s (i'll run a speed test when a more stable release comes out)

so, is it gapps or a kernel issue? newer gapps reduced a lot of problems (though that's a given). also i'd like to point out another error: wi-fi. the mac address keeps changing upon reboot, namely the last three hex values. the first three are always 00:11:22. this wouldn't bother a lot of everyday users, but my workplaces utilizes mac filtering (only way around it is to use the battery-intensive 3g option instead, and i have terrible 3g reception at work where i sit; OUTSIDE my office, i get great reception, but it's bloody hot here x.x)

in any event, if someone could help me out or give me some advice that'd be great.

to summarize:

5.0 gapps + cm12.1 = lots of watchdog events

5.1 gapps + cm12.1 = a lot LESS watchdog events, still happening though

wi-fi mac address gets randomly generated at reboot

phone doesn't get detected by the computer on usb unless you leave it plugged in and do a soft reboot (advanced reboot option; common in most cm12.x instances with default kernels; solid geeb was better, and cm11 was flawless pretty much)

using built-in kernel

att jb radio

clockworksmod touch recovery, the last one (6.0.1.8 i think? it's the last one on their website)

4 gig micro sd card is in the slot, if that makes a difference

one more note: i'm having far fewer crashes on this new install maybe because there are only google related apps (other than whatsapp which i installed right away). future planned apps to be installed:

adobe acrobat

battlenet authenticator

es file explorer

facebook messenger

titanium backup

mx player

aedict japanese dictionary

busybox

greenify

orpheus music player

qr code reader

skype

supersu

terminal emulator

any increase in instability henceforth i'll let you know. also for anyone NOT having greenscreens on the e970, do you have whatsapp? if NO, interesting. if YES, still interesting, but please what version? mine's not the latest (yet)
