The screen damaged severely and touch stopped responding but there is no sign of crack or any kind of LCD display malfunctioning so I decided to repair it and change the DIGITIZER by myself but after watching touch screen (digitizer) repairing videos on youtube I got little confused because in most of the videos I have seen even the screen got severely damaged they were still working but mine is not so I'm wondering even if I purchase a digitizer and install it on my phone but if it might not work then.
So my question is should I purchase a new DIGITIZER available on ebay and repair it by self as its easy to repair it at home? or should I go and repair it from SONY service center or local mobile repair shop but there are two threats:
1). If I go to SONY service center they will charge high (Because for an old phone I don't want to spend more money).
2). If i go to local repair shop they might not use a good quality digitizer which could lead to issues soon or affect overall touch experience.
