I have telus samsung galaxy s2x with android jellybean 4.1.2 (non rooted).
When going on play store I got an error about authentication needed. So I did uninstall updates from application manager (as described in this answer). Now the play store app got replaced with com.android.vending
, which is like the old "market" app.
That app seems to crash frequently. How can I restore the new play store app again?
