Because I'll have new apps downloaded, passwords will be changed for certain apps. The person who is accessing has also told me they can still get in my phone.
They have prior. It's been deleted. I've searched through out my phone for any more but can't find any. I can change the pin right before bed and in the morning my phone will have been gone through.
That tells me your gmail account has been hacked. You need to factory reset the phone. On a computer, you need to get on gmail, and change the password. Then, set your phone up again using the new password. Make it a secure password. 12 characters; letters both caps and lower case, numbers, and special characters. You also need to login to your carrier account and change that password.
