recently my S.O dropped and smashed her Nexus 4 for the second time. i have succesfully replaced 3 nexus 4 screens so far and so i am very familiar with the internals. however, this time as i removed the battery, i noticed that something fell out, upon further inspection i realised that two of the four golden pins in the battery socket (shown in the picture included) had fallen out and are nowhere to be found.

subsequently the phone now will not power on whatsoever.

My question is, can i buy these pins online, if so where. and if not is there anyone who could repair this for me?

All feedback is appreciated. :)

I wanted to temporarily revive my ancient Nexus 4, but the battery is completely dead from what I can tell ... it will shortly come up with the charging sign on the screen when connected to power, then the red LED will blink forever, sometimes it will turn off eventually, but the battery doesn't seem to take any charge.

There's no point in shelling out some 20-30€ for a new battery, so I thought about just soldering on power to the phone (or the battery cable/connector). I see a V- and V+ mark on the battery lead, not sure if it's the 1st and 3rd lead, or 1st and 4th (which is it?) ... can I just put 3.8V on the +/- leads to get it to power up?

Is there any way to recover what I have on the phone at all? Better yet, is there anyway to repair the screen? I will even go as far as purchasing a new phone, removing the main board from my original N4 and placing it in the new one if it would work.

EDIT: Figured I should update and thank anyone who's responded. The utility mentioned bellow is amazing. However, unless the phone has USB debugging enabled, there isn't much hope. As far has I know the N4 stock cannot function as a USB host. So for now, my N4 sits idle on a self until I decide to replace the screen. It's just amazing...four small cracks towards the top, and the touch screen is simply dead. I have an HTC One S where over 70% of the display is completely shattered, and shards are missing as well...and it still functions perfectly. Thanks everyone for the insight...and remember to turn usb debugging on : (

I should note that I got the new display from ebay and while it certainly is new, I assume it's not an original part. I also noticed that my old unit had some sort of shielding on top of the chip that is right above the digitizer connector, my new unit does not have this shielding...

Any help would be appreciated!

always optimizing the apps and auto powering off

I'd like to know if super-glueing the pin back on will fix the phone, allowing it to charge.

I use one of those USB amperage meters and I only see 0.01A current draw from there.

I guess this one is caused by faulty battery?

I am a bit annoying. The use of my Nexus 4 is limited because of low memory capacity (8 Go). Otherwise this phone works very well and I would like not change it just because of low storage capacity.

Isn't there really any solution to increase the storage capacity of Nexus 4?

Looking for some advise,

Thanks

i am looking for an adapter to go from the two power contacts of a cell phone vibrator (nexus 4) motor into two wires, which i will use to activate the remote starter in my car from the contacts of the cell phone when my cell vibrate. i reason that many people already solved this problem to use their cell phones to activate things in their cars or in their homes. do you happen to know where to purchase or how to make such adapter? i do not want to weld wires to the very tiny contacts of the cell phone where the vibrator motors sits because it will very likely burn them.

thanks.

This is my first post here

Since 2 months my Nexus 4 is suffering of ghost-touches like ghost-clicks and periods when it does not react when I touch it.

I'd like to replace the affected parts and I've read that it could be caused because of damaged battery or screen.

I've bought a new battery, but I do not know if I should replace just the LCD display, the touch screen, the digitizer or them all.

Could someone please help me?

PS: an eCommerce link would be appreciated ;)

Thank you very much.

Lately my nexus 4 has been randomly losing signal, i can't seem to get 3g connecton in some places where i used to. The Wi Fi also appears to be weaker.

Besides that, the power button is also now harder to press and i takes quite a lot of tries to get it locked.

I have tried restarting it, turning on/off both the wifi and the data connection and also i tried reinstalling the latest version of Android Lollipop. The phone has always been running on stock android.

Thank you!
