Hello friends:
My wife has the model SM-P605 with Android 5.11 with firmware of Spain PHE: P605XXU1EQB2.
Now, he tells me that Twitter messages have not been updated for some time. I look at Twitter Version and it's 5.22. I want to update it on Google Play, and it does not appears because it is System Application on this Tablet. I downloaded the current Twitter but it does not let me install it: "Not installed" (I suppose it's because of a signature problem).
I delete the data and cache of the application, and it is not work, andnow I do not get any conversation.
I have updated to the last fimware that there is in Sammobile, that is the one of France: P605XXU1EQD1: I do not notice any change, and it does not solve twitter problem either.
Another solution, not the Hard reset?

Thanks in advance
