I have an Android application on Android Market, but some users are complaining about an error shown when the installation starts, just after the download:

One of them sent me a video of this error showing up, and I could see that this error is not caused by the application, but probably in the verification of permission/features process.
As far as I know, this error is just happening on Motorola Droid/Milestone devices running Eclair, it doesn’t happen with Froyo. Unfortunately, I don’t have access to any device like this one in order to run logcat and check what’s going on.
Here are my permission/features on AndroidManifest.xml:
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.location" />
<uses-feature android:name="android.hardware.telephony" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I finally found out what’s happening by getting a Droid device and running logcat:
E/PackageManager( 1280): Package com.mycompany.myapp requires unavailable feature android.hardware.telephony; failing!
Motorola Droid devices running Eclair are not able to install applications that declare
in their manifest. It’s very strange, though, because the Android Market should hide it from these devices. This is probably a bug caused by the changes made to the Eclair by Motorola, since it doesn’t happen with other devices running Eclair, neither with the same Droid running Froyo.
