Why does the green light of Samsung I93 prompt light keep flashing? Then I turned it off and I couldn't turn it on. .

according to your description, I suggest you:

1. press and hold the power button on the right side for 8-1 seconds to start the phone.

2. press and hold the menu button on the lower left corner while restarting the phone to enter the safe mode of the phone, and then check whether it can be started normally.

3. If the problem still exists, I suggest you bring the three-guarantee certificate of the phone and send it to the nearest Samsung service center for testing. Please visit the service center for details: < page=SERVICE.LOCATION& Cid = cn _ PPC _ support _ service _ repairnet _ 12522

I hope I can help you. Welcome to ask questions on Samsung platform. Have a nice day!
