Fun but still glitching*

Problems with battery saver mode, sometimes coming out of the mode causes the screen to freeze. A smoother battle system would be great. Also pokestops sometime do not spin nor do they give any items, doesnt turn purple. Please fix these issues.

*update as of MAY 2nd, 2017
My app has been consistently crashing, which in turn renders my go watch useless. Please fix this.

Suggestions: As a Pokémon Go plus watch purchaser, I feel that there should be a separate mode for the plus and when using it. There is no point of purchasing the plus if I cant use it while driving (which keeps me from looking at my phone and actually helps me pay attention), and it helps driver concentrate driving properly.
Also please allow the plus to choose the appropriate PokeBall based on the Pokémon that is in range or allow it to use the great ball after failing to capture the first time.
