BluetoothOPP.apk - NO, this application organizes file transfer between devices. In case of deletion, you lose the ability to transfer and receive files, as well as work with a Bluetooth headset.

BluetoothTestMode.apk - YES, this apk is designed to test your Bluetooth, which is available through the service code * # * # 197328640 # * # *. Deletion is possible, but in some cases the system tests the BT to determine the duration of the data transfer. After deletion, there may be problems when transferring files, fading when playing music through a BT headset, etc.

DownloadProvider.apk - NO. Provides download files manually and from Marekt.

DrmProvider.apk - NO. Theoretically, you can not remove it. This will lead to the inability to play DRM-protected files, such as ringing tones and sounds messages. I reflect on the fact that if I did not have to play-protected files, then in principle it can be removed. However, we must bear in mind that you will not be able to play any DRM-protected file. This apk takes a lot of memory and is always working in the background. This is one of the worst apk-nis, which does not provide any functionality, but simply protects the standard Samsung sounds from editing and copying.
