I attempted to install Open Heavens daily devotional on my Tecno S7 phone. It keeps telling me 'You have no devices'. What does this mean and what do I do?

Hi! You can try to restore factory settings, but remember to back up important files. If the problem still exists, you can take your phone to our Carlcare Service Center, our colleagues there will help you solve the problem. And if you need us to send you the contact information of our service center, pls tell us the city, state and country you're living in now. Thank you!
