Gcm Doesn't Work On Samsung Tablets

I verified that the app can receive notifications on galaxy nexus tablet (4.2)and samsung galaxy s3 phone(4.1.1), but cannot work on samsung galaxy tab 10.1 (4.0.4) and samsung 7 i

Solution 1:

It started working after I modified the category in the receiver,

from
 <category android:name="com.myapp.example.gcm" />

to
 <category android:name="com.myapp.example" />
