Replaced screen working properly only when the phone is plugged
I just replaced the top glass digitiser of my HTC Desire 510. It is the first time I do this kind of repair so I can't be 100% sure that it was done perfectly.
I bought the replacement top glass digitiser on eBay (not sure if it is an official one or not)
What's happening is :
- When the phone is plugged in (using the HTC charger which comes with the phone and only in that case), the new digitiser is working fine : no lag, recognising the double touch, etc...
- When the phone is unplugged or plugged in with another charger than the one coming with the phone, the digitiser is working in an erratic way : the straight swap are not recognised straight (I used a "paint" app to test this). After 3 or 4 touches, or if the swap is too long, the digitiser (or the phone itself ?) stops reacting and there is a delay of few seconds before I can get some touch recognised.
Could it be the new digitiser being faulty ? Maybe it is using too much power (which would explain why it is working only when the phone is plugged in), or maybe it is saturating the phone with erratic "touch" information which make it the whole system not usable for few seconds ...
I have searched for this issue but could not find anything on the Internet.
Thank you for your help
EDIT : After many tries, I found out that it seems to be due to the digitiser being too far from the LCD screen. I used the thin double-sided tape provided with the digitiser but I may have not tape it correctly. When I press (from the corners) harder the digitiser onto the phone, it starts working fine (plugged in or unplugged). I guess this solve this issue ...
