For all the People having 4.1.2 jelly bean on their lg optimus 4x and facing lagging on their Phone Just follow these instructions. It sure helped my Phone a lot and now works great. Dial at Phone section 3845#*880# and You Will enter a hidden menu. Scroll down menu and enter mlt. Disable mlt. Restart the Phone To accept the settings . for better perfomance Install nova luncher as default Launcher. You Will never have Lag again and it Will gain more ram. It Will use only 600mb ram as the ics version. ENJOy

To brick it, you have to put a lot of effort! :) You'll probably just have to flash kdz file on it and everything will be ok. Go to xda to see how.
This phone is perfect for custom roms and for play with, so learn and be brave, it's unbrickable!

AnonD-154822, 03 Oct 2013My battery was running like a crazy horse, Can you imagine it was lasting 3 hours in 3g use.
... moreso whats was your screen brightness and what were you doing was bluetooth and gps turned on or off did you disable the known bad apps (maps google+ yourube) did you use the seriously shitty facebook apps and so on?
how good or bad was your wifi and 3g signal?
there is a known thing of things you should and
shoulndt do and should test before you blame a phone.
I root it with no pain
There is not other phone with this performance at this price!
don't buy this if you want to put a custom rom on it. it's an absolute pain. i think i just bricked it, but fortunately lg have a recovery tool for that so it might still work. hopefully.

haythem, 28 Sep 2013I want to buy this phone but my problem is phone battery is it good comparing with s3 battery?... morefirst off the temp is a non issue.
battery life is on par with the S3 and if you ask me jb is worse as it uses to much ram but on v10H this phone is just great.

There is your link I assure you, you... morethere is NO point installing another rom its not better at all.
often battery life is worse preformance is worse and it uses more ram then stocl v10 roms.
rooting however is a good thing so you can disable a lot of crap you dont use and use greenigy which should be standaard in android if you ask me.
remorema, 25 Sep 2013I really think that that this is the best phone in the 250€ range; great specs sheet and aweso... morewithout gaming its alright however when you start a game its just sucking it dry.
but this isnt limited to this device hehe my tablet with a much bigger battery is also empty in less then 5 hours.
what you can do to improve battery is when you only use whatsapp is put your 3g on 2g only its fast enough for whatsapp but not for browsing. it is 4 times as power efficient.
other then that just disable maps google plus and dont use the facebook app.
these are poorly written apps that use way to much power.
