Mi3W TouchScreen issue

[DutchMan_1990]

From yesterday I was having a strange issue with my Mi3w, I'm using this phone for a very long time. I have noticed that, a small part of the screen is not responsive. If I want to swipe my lock screen up, then a certain point the touch does not respond. more over the device is not also responding if I reboot my device al least 3 min, after that the screen become responsive again, with recovery mode the issue is there, it does response after couple of minutes. I'm not quite sure what the issue. It's not a ROM issue I guess because I've flashed a MIUI 7 ROM and it's the same issue. Could it be possible that the LCD connector got loosened up somehow?

You wont even believe what i had been going thru
I had the same issue on my mi3 due to which i made a decision to test out a custom rom.
it was little strange for me n let me explain :
While i was using Miui ROM , My phone started going into "Button Non-responsive" mode
While trying to find the cause i realized it was sue to heating on near just above area right in center where board is placed
Non button responsive mode means : Recents app will open, I can still use screen but i cannot use any buttons (hardware/Software based)
I am currently on RR current version : i still get recents open up or G Shortcut open the menu but i can use button (Thanks Custom Roms)

Did you recently faced any liquid/wetting issue on phone ?, if not, still get the phone opened up & get the cleaned up.
Try changing the protection glass or smthing installed or use it naked
Try touching your phone to metal rod where you can static discharge

Cannot comment much as yu are facing issues in receovery too but still try & report

No liquid damage that is for 100% sure. Check the screen test snapshot from here. http://tinypic.com/m/jgs5zb/1 Between those two line touch is not responsive. As I have mentioned that Device is in non responsive mode after reboot and even in recovery mode after couple of minutes. One reapair guys said that the digitizer has doomed. You wont believe the quoted price from 1 of 3 service center here in kolkata 5800 INR, 2 of 3 said, they don't have the parts and company stopped sending the item, please get the work done via local technician, 3 of 3 said, quoted price is around 6800 INR. My best bet is Ebay. BTW do you still have the issue?

Well I do have the issue but my phone is working fine otherwise
buy from Ebay & it should cost you around 1500-1800 only including fittings.
Try it & i might buy a new screen+digitizer too !!!
