Not Getting Notification for Text/Email during Sleep Mode
 

Hello,

I recently purchased this phone and was receiving the notifications for text and email fine during sleep mode until i decided to add some that I found online. now I don't get my text/email notifications until I take the phone out of sleep. Once I noticed this occurance I changed the sound back to one that came on the phone and now I receive the notices fine. I would however like to use one of my own instead of the boring ones on the phone. Is there a way to fix this issue? Is there anyone else this is happening to?

If you can help me I would really appreciate it many thanks for readings :)
