Phone Screen blinks when connected to Bolt

I was connecting my bolt to the cloud using the bolt app in my android phone. After recognizing the bolt wifi and while the app pops up on the message about the frequency of network providers to be 2.4, my phone screen gets bright and dark. Is this normal and should i be concerned? I did not proceed further. Please advise.

@athirap2007 No,there is no need to be concerned.Try reconnecting your device to phone again using a 2.4Ghz network and make sure that your WIFI glows blue and Cloud glows green.Please send a reply if your problem has been solved

Thank you
