fyi, multi screen function is NOT by samsung, it just copied this from 3rd party dev.  i have been using multi screen long before samsung CLAIMED to have "innovated" it

this is why i really dislike apple in the first place, they copied stuff from other ppl's hard work, doesn't give ANY credit to them, then made a big deal out of it by making itself look good because they "made" this awesome feature.  this is exactly what samsuck is doing right now!

if you charge your phone on daily basis, even stock kernel and rom should be good enough.

quad core technically consume more, so starting with NVidia Tegra 3 (first quad core CPU for mobile), kernel already implement auto_hotplug which allow kernel to decide to use only more core when needed.

qualcomm's S4 pro implement it slightly differently using mpdecision - a userland process that something similar. however, since it's not open source, many custom developers decided to removed that and implement the hotplug.

so, even in stock kernel and ROM, it's not that bad.

all stock ROM are using OnDemand CPU governor. in term of power saving this CPU governor is second only to Powersave and sometimes Conservative. most custom ROM using Interactive which may make the phone more responsible, but cannot match the power saving of OnDemand. (On side note, Interactive CPU Governor may not be best for Nexus 4 or any Jellybean android since Project Butter is more effective than CPU governor. it will automatically boost CPU freq on touch.)

there are other settings such as larger data buffering, low memory killer settings, io scheduler, etc that custom ROM may implement to conserve power, but in my testing, they are soooo minor. so custom ROM offer little in power saving nowadays.

custom kernel offers more nowadays. with custom kernel, you can do under-volting. typically allow your CPU to run at same speed (or higher) at lower voltage. other than that, you also can implement lower lowest brightness etc.

although i m still using Stock ROM (with some customization), i m using a custom kernel for power saving and lower heat. ohh... ya, custom kernel allow me to calibrate Nexus 4 screen too, which LG and Google really do not do justice for the IPS screen.

Scary mate. U use nexus 4 earpiece or 3rd party earpiece??

Seems like LG Service center open during weekday only..According to what written at first post.. my power button seems getting loose already How much to change that at LG Service center?

Someone mention before. Forget how much already, RM50 or 80

I believe many user have problems on their power button. Mine as well. 

Nice phone but not so gd power button. T.T

Damn!! Now my vol down button lose edi, cause i use it as my wake button.

do the have any other batteries. instead of 2100 i mean maybe a little bump up just like what samsung being do.

I don't think they can do that. They have rules and regulation 

I lazy to wait too. And, I don't have any spare phone to use while waiting...

Nexus 4's buttons are lousy. Many users have reported the similar problem.
So, it's not our fault.

Sound impressive...
My Display have some backlight leaking too. Not sure if they'll fix it on the spot or not XD...

haih... I'm going to send it to SC in SG to fix just before warranty expires

I plan to upgrade to Nexus 5 though...
but leaked & potential model suggested it's being manufactured by LG again
not sure if it's a good news

I just made a mockup based on the dimensions given.

Dimension of screen is 66.2mm x 107.2mm
Dimension of body is 68.2mm x 132mm

The screen is placed directly in the middle.



Look at that bezel. 

Anybody have this problem?
11pm had 70%. Wifi off,  data on,  wake up in the morning only 50% left.
Was fine before.  Just noticed it last few weeks.

I only have one complain for it,the camera is too big,other than that everything is good 

I'm not a camera pro, so I'm not going to pretend to be one. But basic logic tells you that the bigger the lens is the more light you can get into your sensor, hence better photos.

A quick Googling I found a few links that might help explain why bigger lens is better...

Does a bigger aperture create better photos

Does a bigger camera lens always produce a better picture?

Are bigger lens in a camera a better thing then small lens?What are the advantages of a bigger lens?

Faster in other areas but still slower when loading odex compare to deodex.

The so-call faster mostly due to bionic/krait optimization. You can do that without customized ROM. I am on stock ROM, can get 25k 24k antutu score on 1.5ghz.

ps: sorry, 24k only.. err.. my point is, it's ok to use deodex ROM for customization, important to many people, but whenever u use it, bare in mind there is a tiny teeny bit of performance hit.

That's why I never like Samsung products,oversized and plastic design,but for the size,they really did a good job on galaxy s4,screen on s4 is amazing too,just the plastic design I dont like

 
Hopefully, Nexus 5 will have the same price as Nexus 4(original price/launching price).
So, it'll be highly affordable.   

I don't know how to flash factory image via cmd,all the details in XDA is too complicated,I normally flash using nexus 4 root tookit

Just saw this article someone shared earlier on ... wou ... i would get these to replace Nexus 4's camera and probably stick with my Nexus 4 longer ! LOL

For Win 7/8, try update the driver for /Portable Devices/Nexus 4 in Device Manager.
Use (Standard MTP Device) ---> MTP USB Device

Win XP, can't help, I also dying seeking for driver.

Tried. Not working either.

[attachmentid=3621652]

EDIT: Gonna try toolkit as I got free time now. Will update later.

Tried many many times already,failed also
If its that simple,I wouldn't have go through the whole night and find a solution
Booting into Recovery,fastboot,or reboot command works for me at nexus 4 root toolkit,the problem is the phone is charging,and PC got sound,just the PC never detect my device,sorry I not gay xD

sad to say,all the method you guys said didn't work well,thanks you guys,I think I will just manually upload files to my Box account one by one

Seriously piss off today,nexus 4 root toolkit can detect through fastboot,but can't flash stock rom and wipe all data,I need to sent to warranty this Friday,what to do
