I have the EXACT same problem. Internet may not be available. Exclamation mark beside the wifi logo. Can use the wifi for all other app except google play store. All my other devices are fine including my very old iphone 4s and my toshiba laptop. Read online about this issue and appaerently it existed for previous samsung phones as well. When will samsung fix this issue. I was almost happy when i left apple and came to samsung.
