Remove hardware & software fetures from aosp android

For Remove Hardware features check following files in android source :
 
1. Check the device.mk file for your device(Like : device/<vendor>/<device>.mk)
2. Check the common.mk file for your device(Like : device/<vendor>/common/common.mk)
 
 
There both files is probably a line like the following:
 
PRODUCT_COPY_FILES += \
frameworks/native/data/etc/android.hardware.location.gps.xml:system/etc/permissions/android.hardware.location.gps.xml \
 
Remove this line to make sure that the GPS permission file is not copied into the filesystem. For an existing filesystem, delete this file from the /system/etc/permissions directory and reboot.
Similar lines are to be removed to disable Bluetooth, Wi-Fi/Wi-Fi Direct etc.
 
 
3. also in android source for all handheld device have file permission files & software system features
/frameworks/native/data/etc/handheld_core_hardware.xml

devices/<vendor>/<device>/BoardConfig.mk
devices/<vendor>/<device>/<device>.mk
