I'm trying to sign into my Amazon account to get my Apps back from Target and other places on my phone and I just changed my password on my account so it should be right but it won't let me in

Hey Clemente, thank you for the question. If you want to reset the echo device password, you may need to change the password of the amazon account you used to make purchases from the amazon e-commerce site. Reset it by clicking on the forgot password button on the amazon site then follow the instructions.
I hope this will solve your problem.

GO TO SETTINGS GO TO APPS RUNNING APPS OR ALL AND LOOK FOR EMAIL THER YOU WILL HAVE AN OPTION TO DISABLE FORCE STOP AND BIT FURTHER DOWN ON SCREEN CLEAR CACHE AND RESET DATA. SO CLEAR DATA AND CACHE THEN FORCE STOP IT. THEN GO BACK TO YA EMAIL AND TRY SETUP UP EMAIL ACCOUNT THIS SHOULD DO THE TRICK FOR YOU. IF NOT GIVE ME A SHOUT.

Not sure what you mean by "unblock your Samsung"? If you mean it simply wont log into your Google account you might have to do a backup of your phone then do a factory reset and set the phone back up from scratch.

i would contact amazon because this is related to your account security

Problem
You see the following error code and message when you try to sign in to Xbox Live:

Account does not exist.
Status Code: 8015D002

This may mean there's a problem with your account. For example, the security information for your account may need to be updated.

Solutions
Solution 1: Did you recently sign up for two-step verification?
If you recently turned on two-step verification, you may not know how to sign in to apps or devices that don't accept security codes. Some apps (like the mail apps on some smartphones) and devices (like the Xbox 360) can't prompt you to enter a security proof when you try to sign in. If you get an incorrect-password error with an app or device, you'll need to create a unique app password to sign in. After you sign in with your app password, you're all set to use that app or device. You'll use this new app password to sign in to your device instead of using your Microsoft account password.
You'll need to create and sign in with an app password once for each app or device that can't prompt you for a security proof.

1. Sign in to your Microsoft account.
2. Under Password and security info, tap or click Edit security info.
   If you're prompted for a security proof, enter it and tap or click Submit.
3. Under App passwords, tap or click Create a new app password.
   A new app password is generated and appears on your screen.
4. When you're prompted for your Microsoft account password on your Xbox console, enter the app password that you created online.After you sign in with your app password, you're all set to use that app or device. You will use this new app password to sign in to your device instead of your Microsoft account password.
   

Solution 2: Verify your Microsoft account security informationFollow these steps:

1. Visit Microsoft account.
   Note If you forgot your password or can't sign in using your password, reset your password.
2. Click Edit security info.
3. Verify your security information. For example, verify the Phone number, Alternate email address, and Security question information.
4. Sign out of your Microsoft account and then sign in again.
5. Try to sign in to Xbox Live again.
