title: Does Samsung S4 support BLE application?
body: <p>Recently I received a Samsung S4 with android 4.2.2 and now I am trying to install BLE apk for testing some things.
  I would like to know is there any BLE apk available for android 4.2.2?
  I downloaded an apk from the following site but does not work, maybe it just supports by android 4.3.
