David,
Thank you for answering my message. The “Basemap Selector” option was selected. Something I found out today. The map (AFC Field) was opened in ArcGIS on a Motorola RAZR Maxx. The “Basemap Selector” (three dots at the bottom middle) was present and functioned correctly. My phone is a Samsung Galaxy 5S and the “Basemap Selector” does not work on it. The Maxx is older and I suspect the operating system is different from the Samsung. So, I think it may be an operating system issue. The people in my agency who use ArcGIS have a Motorola RAZR Maxx, Ultra, or Droid Maxx except for one person. We can get by unless more Samsungs are purchased. However, if you know why Samsungs do not allow the “Basemap Selector”, then please let me know. Thanks again. Jim
