Though the condition was not totally out of hand because most part of the touch screen was functional. So for temporary workaround I installed Handy Soft Keys, an android app which lets you have pie menu on the screen to simulate Home, Back and Recent Operations.
But ergonomically it was pretty annoying and time consuming. So I finally decided to find Nexus 4 repair center. I found it in a near by Mall. But discovering their fees (around $170) made me realize that I will have to repair it myself.
So I started with -
The problem was a short circuited Digitizer.
I only needed to replace the digitizer. But it is a complicated process of separating the digitizer from the LCD and gluing the new one again with working LCD. So I thought of getting the pre-assembled unit of digitizer and LCD and replacing it myself.
Repair - Prerequisites
- Ordered Digitizer + LCD assembly and the Tool Kit from eBay. Tool kit must have T5 Torx Screwdriver, Philips #00 Screwdriver and a Spudger
- Ordered adhesive tape from eBay
If you are doing this for the first time then I would suggest to have someone around you who can help you keep your calm because it needs lot of patience to disassemble and assemble the phone. I took guidance from the Youtube video and huge encouragement & help from my Wife to fix the phone.
Important step is to properly glue the assembly to chasis.
To fix the Volume Rocker Issue simply use a screw driver to bring the spring back to its original shape so that it connects with the circuit end points on pressing. It generally stops working as it gets compressed due to the impact of falling on the volume button inhibiting it to make connection properly.
- I tried saving the LCD from breaking but it was so tightly glued together that I had to break it.
- Few screws were very tight so one has to be careful while opening them because if you try too hard you might end up damaging the grooves of the screws and it might not open in the end. If something bad has already happened use 1 point bigger screw driver and instead of moving the screwdriver, try rotating the screen and keep the screwdriver stationary. (Totally my wife's Idea! Yes it worked!)
- Don't loose hope even if few things don't work out the way you have imagined.
