amir, 30 Jun 2013Hi everybody
Help me please.
I bought this phone about a ... moreThe first caller id issue seems to be brought up on rare ocations on the net but by people with all different phones so this is most likely not a issue with your phone but ith a app on your phone or a bug in the fsoftware.
the only possible way to try and see if this is true is making a backup with the build in backup app (make a seperate backup of your contacts) and do a factory reset.
after the reset restore your contacts and have people call you to test it.
if you have any alle that has anything to do with contacts get rid of it and test before the factory reset.
second sounds unlikely to be a hardware issue seeing your not holding it so once more im lokking at a app that might be responsible for this.
ad for battery life this most definitly is a app issue and have bin talked about a lot here.
start with removing all battery monitors wakelock monotors and taks killers/managers you installed.
then disable mapps, google streetview and google+ and delete facebook app if you have in installed.
its a bad app i tested it again after months 1 day ago and lost 30% of my battery to it so deleted it again.
also disable sync in options (you only need to sync after you make changes to your phone like adding contacts in whatsapp or caller contacts and you can do this manualy by clocking on it in that list.
make sure your bluetooth and gps are off and make sure location services are disabled (if not apps may be allowed to enable gps shortly to see your location).
disable 3g when you have wifi and disable wifi when you go outdoors and dont have wifi.
with all that disabled you should se a significant improvement in battery life.
manual management of the phone is a hassle at first and you will make mistakes and curse because you have no internet at times (because you forgot to turn it on) but the benefits are greater then the hassle.
if you could post some stats (screen on time + total time active without gaming) per full charge we can tell you if this is in the normal range.
good luck in solving your problems.

core disable, 30 Jun 2013I've got the same battery problem. I'm considering install ... morehi i prefer quadgearbox it just disables the 2 cores and leaves the other 2 running on 1.5ghz.
this keeps everything smooth and stil you have a gain in batterylife.
the problem from not being able to turn the 2 cores back on lies within some android apps but is easy to get arruond.
the problem excists because some apps keep the cores awake for to long this means as the cores are actrive you cannot swotch the other 2 cores on as a ap is active.
if you really want or need to (which i cant immagine) turn the 2 cores back on just reboot and disable all apps trou application manager> active apps and turn on the 2 cores.
or just tap the turn back on button a few times it will turn back on ive done it many times to test.
the only disadvantage is you cannot downclock the cores but in my opinion downclocking is bad.
the higher mhz the cores run themore power they consume and to my knowledge the power preformance ration isnt linear.
this means that if at 500 mhz the core uses 1 watt on 1500 mhz the core doesnt use 3 watts but more like 3.5 watts (dont know the exact numberts its a example).
this makes having 2 cores active the wiser choice because you can run 2 cores @750mhz for the same task and use less power.
unless you ofcourse underclock a LOT like a 800 mhz cap on both cores then its usefull but im not sure the phone stays smooth then.

Hi everybody
Help me please.
I bought this phone about a month ago.
I have some problems with it now.
First, sometimes when someone calls me even though their names are already saved in my contacts, names don't show up! And you can see just the number. But when I look the call logs(history)I can see their names.
Second is since my phone hit on the ground(but it wasn't serious and it was covered with protector)sometimes when I'm not using it light turns on and the lock screen appears and again it turns off!! I just look at it without any single touch. I thought it might be because of antena or network going off and on so I put it on the flight mode but it kept happening again.
also I'm not pleased with battery life.
I"ll appreciate any help in advanced. Let me know please if you know the reasons and whether they are fixable or ...

I've got the same battery problem. I'm considering install app to manage the core.
LGGearBox or quadgearbox, which one is better. I found someone saying they can't get other cores back when disabled, and others talking about even factory reset the core speed wouldn't return to normal. will these damage the cpu? or brick the phone?
I really hope you can give me some experts advices.
Thank you guys.

4X HD User, 29 Jun 2013Yes, battery drains faster even if we dont use phone, when ... more2/3% per minute is absurd i get 4 hours use time out of my phone which means no more then 0.41 % per minute and i mostly use it for whatsapp or browsing.
i do have 2 cores dusabled but that only gave me 45 minutes extra at best.
you can download the app to disable 2 cores here :
https://play.google.com/store/apps/details?id=com.domenukk&hl=nl
youl barely notice a difference in preformance.
but the main thing to do is manage your phone dont be lazy.
-manualy close apps before going to bed (slide them away and close them under applications)
-slide apps and close them when you dont use them for extended time.
-if you use apps in the morningto drive to work or whatever when you arrive take the time to disable it in apps again maps is a BAD app only activate when needed but best is to download a alternative like synergic.
-dont download apps with adds go for alternatives or the paid versions, apps with adds download net adds all the time if they run in the background which nog only uses your 3g limit but also soaks energy.
-dont wait for the screen to time out press the button if you put it away.
-get rid of the stock browser and use chrome (do NOT update to the latest version of 22 may tho its bugged for tegra3 devices google messed up.
-get rid of the facebook app and make aa shortcut on your desktop the facebook app drains battery you wont get notifications but the battery gain can be great.
-if you have cache cleaners get rid of them cache prevents you from having to reload data and recalculate it which saves not only 3g data but also cpu time which = battery life.
-get rid of task killers they are useless and evil they kill apps that android boots up automaticly again anyway which results in used battery life for loading the app used battery life for killing the app and this goes on in a circle.
-dont use battery/wakelock analizers permanently they are evil battery drainers as they monitor the battery constantly the apps constantly uses resources.
-get rid of apps that stay active in the background if they dont need to (mostly games).
-if you dont care about goole+ disable it its a battery drainer.
if you do all this and do it correctly you will greatly extend the battery life but as said it comes with compromises.
if you want to use some of these apps realize it costs battery life.
the final solution is buy a mobile battery pack if you but a 10.000 mah pac you can charge your battery 4 times a day from the pack giving you even in worst case scenarios 8 / 10 hours use time.

Anonymous, 29 Jun 2013i think the Nvidia Tegra 3 is so badly designed. i disable ... more15-20% in 10 min is IMPOSSIBLE period.
the tegra 3 design is just fine its just a fact that quad cores eat a lot of power tey are afterall quad cores they should use 4x more then a single core.
but you get preformance in return.
chats the choice you made when buying this phone if you need superious battery life buy a old xperia arc 1ghz single core they last quite a bit longer but they will lag and stutter all over the place and cant handle the pretty HD screen smoothly.
everything comes with compromises power usage is the compromise of current qquad cores and this is unlikely to change anytime soon ad the new a15 cores only suck up more and more power at higher mhz.
but if you use 15 or even 20% in 10 minutes id do a hard reset and get rid of some crap as something is wrong. even when gaming 2 hours should be possible which means no more then 8.3% drain per 10 min.

i think the Nvidia Tegra 3 is so badly designed. i disable the some preloaded apps. when screen off, the cpu switch to the fifth core, battery usually 0.5-1% per hour. however when running some app even surfing the internet when screen set to 20% brightness, sys monitor show tegra fired 4 cores up and eat battery like hell. 10mins 15-20% battery is gone.
my note 2 with bigger screen, and set @ 50% brightness, surfing net. 10mins usually less then 5% battery is consumed. sys monitor shows only 1 or 2 core is used.

diogo, 27 Jun 2013I've gone back to ICS.
My problems with the JB update were... moresadly it seems lg choose to boot up with everything preloaded. not my choice sadly.
id prefer to boot with as little as possible and make us choose what should start on boot but no dev seems to agree as its still not possible in any rom even tho android is capable of it.

Your phone might be thinking the Memory Card is being removed.
Try adding the mp3 you want to the ringtone folder in the phone memory. should work,
I removed the MC to try to update the phone (had a problem while trying to update, but, gonna try again later, as soon as I'm answered at XDA if I have to do factory resets or not), when I turned it on again, my BF\s ringtone was saved due to being stored on thehpone, but my general ringtone returned to LG original, even if the MC was back on the phone.

I've gone back to ICS.
My problems with the JB update were:
.Really bad battery duration.
.phone slow as hell.
.erratic in some functions such as lock/unlock screen.
.it overheats even more (just by having the screen on).
.more RAM consumption. (it's funny cause I also have a note 2 with JB and it consumes less ram than this phone with the same JB, and believe me the note 2 has a lot of functions)
I experienced all of this only with stock apps installed.
