[flycaster1]

I am trying to improve the performance of my FireTVstick by deleting some apps. Presently, I have three Amazon Video app and only want the best one; however, I need some help in telling which is which. So, let me describe them to you:

1. Rectangular icon, says "Prime Video," version PVFTV-120715, 22.95 MB size
2. Square icon, says "Prime Video," version 4,12,12-Googleplay-arm7a, 121MB size
3. Square icon, says "Video," version FireTv,270.48801, 72.74MB size

Thanks.
