I think I have every feature turned on, but the only features I can find are (as I mentioned before) travel, weather, sports and finance. It has full access to my web browsing, search and location, and GPS is always on. I get nothing except traffic and weather (and neither are as good as I need or get from other apps), and I don't follow American Football or Soccer, so the sports teams are irrelevant. It has never mentioned a restaurant, a museum, an event, a petrol station or anything else for that matter. It is disappointingly shy.
Have you asked it for restaurants in the arera or types of restaurants like "seafood"? Have you asked for the nearest gas station. I was lost and the gas light came on and I asked for ther nearest gas station and it pulled it up. When in the country this saved me from having a nice walk. With the gps turned on I say places of interest and it gives me listings of places withing 20 miles. I was in Central Park and hear music and asked whats going on and it pulled up a free concert in the Park which I had no idea was happening and enjoyed going to that event.
I think you just have to ask reasonable questions. Like the where is the nearest gas station, navigate to XYZ, Places of interest, where's a a good place to eat., what's todays NBA schedule. Navigate to the nearest Home Depot., Best Buy, "supermarket of choice". O.K Google Set the alarm for 6 a.m. Also remember If you don't ask about things relevant to what you like how is it suppose to figure this out.
I dare you to make sure the settings of voice interaction and all features are turned on and then ask it to navigate to the nearest gas station, or the places of interest, or where is the nearest Walmart. I really fail to see how this works for me and every one that I show how to set it up results happen. I think it still needs a little help but for the most part it is a very good feature to have especially when home address, work address, and cards are set up. When asking things like I mentioned it works very well.
I just asked the square root of pi it answered me with the square root of pi.
Gmail may have a play in some things However; getting nearset gas station locations or asking it to navigate to nearest locations, or finding places of interest has "nothing" to do with Gmail.lol
