Hello, I'm using Samsung Tablet 4, I know it is kind of an old device, but I'm using it anyway. I just suddenly got the locked screen with a message that says, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data. And gave me an option, reset device, where I can't even move forward. I just have no idea how to deal with this problem. I mean, I don't want my data to be erased, they are really, seriously important to me. How can I do with it? What does integrity verification mean? I'm eager for my date to be saved. Please tell me the solution. Thanks ahead of time for your response.
