accelerometer dont work after dropping
I got an iPhone 5 to repair after dropping. The problem was in next: in any position Safari (and other apps) rotate to landscape mode. Data Collection (app from App Store) shows state of sensors (Accelerometer, Gyroscope and Compass). The program shows that X and Y axis are stick. in internet I found that iPhone 5 use LIS331DLH, we soldered new chip. But it did not help. Data Collection showed that sensors dont answer any datas. Studying data-sheet of LIS331DLH showed that it has slave address 0x32. Original chip has address 0x3a. Using logical analyzer we saved data exchange between cpu and accelerometer (u18). Log data showed that exchanging data stopped on reading slave address of new chip. The question is: Whether Apple use special edition of LIS331DLH or in fact another chip? Or maybe is it possible to program chip before soldering?
p.s. symbols on original accelerometer chip are 2229/DSH/
symbols on new accelerometer chip (LIS331DLH) are 8247/33dh/
Ist dies eine gute Frage?
