I have written a program for Bar code scanner application it works fine in the Samsung Galaxy S551 but it didn’t detect the bar code in the Samsung Galaxy Y.I compared both the devices and found it that might be due to Android version compatibility.I build application for Android 2.2 and tried to ran it on the Samsung Galaxy Y so again I build application for Android 2.3, I got the same result.Samsung Galaxy Y still didn’t detect the bar code…
The Samsung Galaxy Y has no auto-focus on its camera. This prevents it to get a sharp picture of a bar code and in this way it cannot read it.
I do not know for sure if this is a hardware limitation but I think it is.
