context sevices has stopped topic

Hello

I have a rooted samsung galaxy tab S / 8.4 with Kit Kat 4.4.2

I have read various similar posts regarding the same issues and have tried various ways to remove or rectifiy the error message that appears onscreen. 'Unfortunately context services has stopped'.

I have cleared the dalvik cache from within lucky patcher.

I have wiped the cache partition from within the recovery mode.

I have cleared the settings / storage / general / cached data and the actual context service app itself.

I have read other posts referring to renaming the context service apk, so it will not run, yet where is it located?.

Or have read that if you access the system/priv-app folder and replace the context service apk with another version of the same file.

Ive tried to access the system/priv-app folder via the root explorer program, but it deosnt find the folder.

Can anyone shed any light on why this error message appears and how to remedy it?

Thanks for reading
