Are you sure that your smartphone is connected to the internet? Check your browser and see if you can get online to www.amazon.com.
If you are connected to the internet, and you cannot download books from the play store, you may not have an Amazon account established.
Sorry. I confused this question with another one. What I meant to say was that you may not have a Google account established. Do you have a gmail address?
I do not have a solution to your problem. You can try performing a factory reset. You can back up your personal data first. This is a last resort. If it does not resolve the problem, you should return the phone where you purchased it, because this would indicate that it has a defective operating system.
If you need assistance backing up your phone and doing the factory reset, please let me know. or, if you still want a refund, I will contact customer service on your behalf.
Fine. Thank you for giving me an opportunity to be of service.
I apologize, but i am unable to refer your question to Customer Service. You will have to contact them yourself.
