Google Keeps Asking for My Password on My Phone

While using my Google account on my phone, I am experiencing ongoing frustration because the system keeps asking for my password repeatedly. Even after I successfully sign in, I am prompted to enter my password again shortly afterward, which is extremely disruptive when using Google Play and other Google services.

I have even taken my phone to repair shops in an attempt to resolve the issue, but none of them were able to provide a permanent solution. After logging into my account once, I expect my account to remain signed in on my phone without constantly requesting my password.

I request that this repeated password prompt issue be properly investigated and that my account be made usable in a way that remains secure but does not require me to re-enter my password every time.
