Thanks to its terrific camera and mid-range price point, Google's new Pixel 3a and 3a XL smartphones have been fairly well-received by the public, however, that hasn't been the case for all users.

According to numerous reports on Reddit, some users have started to experience random shutdowns from both the Pixel 3a and 3a XL, with a hard reboot (sometimes requiring the user to hold the power button for up to 30 seconds) being the only way to bring the phone back, as reported by Android Police.
