Should I replace only the digitizer or the whole LCD?
unfortunately, my LG E975 dropped out of my pocket while entering my car and landed on the threshold exactly in that moment, when I shut the door at full tilt smashing the phone. Of course the glass shattered completely and now the touchscreen is not working. I can still use the hardware keys and the LCD works quite fine, but I just can’t interact anymore with the screen. And if I tap with a bit more pressure on the screen, the LCD shows signs of pressure, too.
To get a better understanding for me in general: There is the LCD, which has no touch functionality and only shows the image. On top of the LCD sits the glass with the digitizer build in. The digitizer registers the fingers on the glass and sends signals over the digitizer flex cable to the processor, which then changes the image on the LCD. Is this correct?
Although my phone is quite old, it runs better than ever before (now with Android 5.1), so I actually don’t want to buy a new phone. I’ve never repaired a phone before, but I like doing things by myself and there are some guides online. Anyways, I have nothing to lose and get the chance to gain experience for other phones in the future.
Now there are two options for me on ebay:
Buying only the glass with the digitizer flex cable (ca. 15€) or buying the glass with a full new LCD (>60€)?
Because the LCD is still working, could I actually just go for the cheap glass to regain the touchscreen functionality?
But does the glass offer always contains a digitizer? I don’t want to get just a useless glass cover for the LCD from a cheap Asian reseller..
How difficult and risky will it be to separate the glass and the LCD?
And could it be possible, that the LCD got still damaged when it got smashed by the door? How can I check this? In this case I will of course replace the whole display..
Many questions, I hope you can help me at least with some! I’m also planning to create a guide for iFixit in this occasion, if the replacement will be successful.
Thanks a lot in advance!
