So, I have been working with the S60 phone for a couple of weeks now. I wanted a rugged phone that could survive a few drops, was water resistant, had a pretty big battery, had a loud and clear speaker especially for the speakerphone, good reception, a bright screen and was not too big. This phone meets all of these criteria (presumably, in the case of ruggedness, as I have not tested this, I bought a full case anyway).I would have preferred a bigger battery (like the S41, 5000 mAH), but the battery lasts a couple of days if not used extensively, maybe 3 days per charge when just idling (no bluetooth or WIFI), so minimally acceptable. It does fall short when used for navigating on Google Maps, so I need to keep a charger in the cars for this purpose. I retrofitted my last phone (Samsung S4) with a monster 7500 mAH battery, that was great. Can't do that here, can't get to the battery.The FLIR is impressive, not that I am any expert in FLIR technology. I have found many uses for it already--while this is "low resolution" FLIR, and the FLIR software available from their website does not recognise the files, it is still quite useful. I can see through the walls and ceiling in my old house and see missing insulation! I found insulation leaks in my heating system. I can easily see where the dog has walked 3 minutes after she leaves the area. I used it to find thermal leaks in my heater duct insulation. Study the thermal gradient in my refrigerator, 45 degrees on top, 29 on bottom, don't put lettuce down there! I checked out the heat distribution from a new hot air register I installed in the house, see photo. Very cool.As reported by many, the regular camera is pretty mediocre, certainly poor relative to expensive ordinary phones these days. It is not unusable, as many say, but it is not at all impressive. Color balance is way off when used indoors, and the software offers no EFFECTIVE way to adjust this as best I can tell.Of course you can do this in Photoshop later, but a hassle. If you are shooting outdoors in the daylight to document things, it will be mostly fine, but other than that, not so good. It works OK for macro shots, which I used with my prior phone, if you download the Microscope app. It is slow to focus and take the image. Maybe a better app will improve the usability of the camera. So if you just need to document things on the job site, or take photos of the kids at the amusement park, it will be fine. But if you expect a lot from your camera, you may be disappointed.Note that I do not play games on my phone, so I have no basis to judge that. It runs fine with all of the apps I had on my old phone.I knew going in that the camera was marginal, so I am not disappointed. Same with the non-removable, marginally sized battery. So overall I am quite satisfied with this purchase. I hope that the next generation addresses the camera and battery size issues, because other than these it is a great phone. A better camera with some real controls and software and at least 5000 mAH and it would be perfect!
