I am exploring the possibility of using my phone as the main navigation device for touring. The phone (Pixel 2) is IP67-rated and I was planning to use it without any additional waterproofing, just attached to a Quad Lock handlebar mount.
I am now wondering whether serious rain is going to kill it or at least render temporarily unusable (touchscreen issues come to mind)?
Since I don't really want to find out the hard way, I thought I'd ask here in case any of you have relevant experience.
For comparison, my Edge 810 is IPX7 and has been fine in all sorts of conditions.
As an alternative to putting my main phone at risk, I am contemplating getting a cheap IP68-rated rugged phone (like BV5800 Pro). Not really sure whether it's likely to fair better (higher ingress protection rating) or worse (presumably cheaper construction).
P. S. Having looked into this further, I came across MIL-STD-810G. There are quite a few devices that advertise this, but I am not sure how much attention to pay to it (given that it's self-certification just like IP ratings are)?
P. P. S. There are phones that are specifically advertised as being operable with wet or gloved fingers (for example CAT S41). Not sure whether this in any way relates to MIL-STD-810G, or how much attention to pay to it. Would love your input.
