Google Pixel 4a troubleshooting

Published specification

What is true of this model and changes how you fix it

• Hardware — Google support tech-specs page
  5.81-inch OLED display, 3,140mAh battery, 6GB RAM, Snapdragon 730G, 128GB storage — no 5G radio, smallest battery in this group.
• Tier — older value (Snapdragon, NOT Tensor)
  A small pre-Tensor value Pixel with a Snapdragon 730G, past its update window. No Tensor AI. Stock Android. Age and chip generation, not faults. A physical rear fingerprint sensor (more reliable than the later under-display ones).
• No Tensor AI / updates ended
  Newer Tensor-only features are unavailable, and guaranteed updates have ended.
• Age
  An older battery may be weak; a replacement helps if you keep using it.
• Updates
  The Pixel 4a stopped receiving major updates after a certain date, so check Settings, System, System update to see what is available. Security matters, so keep the phone up to date.
• Battery and storage
  A phone of this age can have a worn battery. Check Settings, Battery for usage. Free storage by moving photos to Google Photos.
• Battery and performance
  A phone of this age may have a worn battery. If it dies quickly, check Settings, Battery, Battery usage and consider a battery replacement. Close apps you do not use.
• Backups and resets
  Back up with Google One before any reset. A factory reset from Settings, System, Reset options erases data. Use it only if other steps fail.
• Support and trade-in
  Google's support site lists the software status and repair options for the Pixel 4a. If the phone is past its update period, consider the security risk. Back up before a repair or a trade-in, and sign out of your Google account.
• Camera and storage
  The Pixel 4a has a single rear camera that relies on software. Free storage matters for the camera: keep several gigabytes free. Google Photos can back up and free space on the phone. If the camera app crashes, clear its cache from Settings, Apps.
• Updates and security
  The phone's update period has ended, so check Settings, System, System update for any remaining security patch, and be careful with apps from outside the store. Use a strong screen lock and keep a backup.
• Battery care
  Avoid leaving the phone in the sun or in a hot car, and keep its charge between about 20 and 80 percent when you can. Use the Adaptive Battery setting, which learns which apps you use.
