If your lcd is fine no need to sell out 5k for whole unit...
Just go into any reputed repairing shop and they will change it digitizer for max 1500..
Got one replaced more then a year ago price that time was 4.8k. Spending 8k on nexus 4 is not worth u can buy a used one for 5/6k or buy the display from Ali/eBay.com they are cheep there.Sorry I might be digging a very old post.
But my nexus 4 screen is not responding at few places. Screen is not cracked. It seems 100% fine. But touch problem.
When I approached service centre they are saying display needs to be replaced and it costs around 8300 INR.
Just wanted help from you whether it is worth the amount which I am spending?? Or I have to ask for replacement of specific parts which costs me less?
