TCL SIGNA - Power Up in Safe Mode

Here's how to boot your SIGNA into Safe Mode to help determine if an app is causing it to freeze, reset or run slowly.
Safe Mode puts your phone in a diagnostic state (returned to default settings) so you can determine if a third-party app is causing your device to freeze, reset or run slow.
An alternate method is available if the device can be powered on and is responsive.
  1. With the device powered off, press and hold the
    Power button
     until the 'TCL' logo appears then release.
    Volume and power buttons
  2. Approximately 2-3 seconds after the 'TCL' logo appears on-screen, press and hold the
    Volume down button
    .
    If pressed too soon, device won't boot into Safe Mode.
  3. Continue to hold the
    Volume down button
     until 'Safe mode' appears in the lower-left of the screen then release.
    This may take up to 45 seconds.
