    It seems like a prompt is asking for your approval. – esQmo_ May 16 '17 at 20:25
  • What @esQmo_ said is right; lots of Chinese phones implement such extra "security" measures to prevent USB-sourced malicious installs. – Andy Yan May 17 '17 at 0:29

For LeTv Le 2, Go to Settings > Fingerprint & Password > Other Security Options > Install apps in background , Set this options to Yes.
