The Pixel 4a and 4a (5G) smartphones integrate many smart features, such as the latest Google Assistant or a smart battery that learns which apps are used most frequently and limits battery usage for less important ones. The camera automatically corrects colour and light thanks to HDR+ and also offers functions like portrait mode, top shot, night vision with astrophotography and fused video stabilisation. The Titan M security chip protects passwords, Google Pay and login data.
