I have to make surgery to my lovely Jolla (Angry Birds Stella) - call speaker was cracling almost all the time. Sadly, after successful replace I found non-working digitizer. All flex cables looks fine and rest of components works as expected.
Nah, why I writing it? When phone display turns off, the notification LED quickly blinks double time with turquoise color. What does it means? Is there any possibility to fix non working digitizer? (uhm, I don't believe it, but for 2 seconds display recognised touches)
UPDATE: I found this: When phone is on charger, touch screen reacts on touches (double tap) without any problem. When phone is turned ON for alarm, touch screen reacts on touches (swipe gestures) without any problem. When phone is turning ON, I'm able to interact with UI for few seconds.
Then nothing... I guess that isn't absolutely hardware problem. Calibration issues? I still didn't tried recovery, so maybe it could help, but I'm not sure, if it helps.
UPDATE: Recovery didn't help.
