Replying to Placement of phone...

So I'm making this to get help so my phones decide not to break on me anymore. I have yet to figure out the best place to put my phone while I'm riding. I've tried my jacket pocket, my pants pocket, shorts under-neith the snow pants and my phone just seems to not work after. It has held up so far this year but once again it broke on me. It gets wet or something and just starts flipping out. Any suggestions, I was thinking about a plastic baggy? Not totally sure but could use some help.Thanks.
