Android Auto warns Android 10 drivers of a cutoff Google has yet to confirm

A driver plugs an older Galaxy into the car and gets a notification that Android Auto will "soon stop working on this phone" ^[1]. According to 9to5Google, the notification comes without any additional context ^[1].

The cable matters here. Wireless Auto already requires Android 11, while wired Auto still accepts Android 9 Pie ^[3]. An Android 10 phone therefore connects by wire or not at all ^[17]. TechRepublic says the warning could mean Android 11 becomes the minimum for both modes ^[4]. That would raise the wired floor by two versions and catch Android 9 phones as well ^[18]. 9to5Google addresses its advice to Android 9 Pie owners too ^[10].

What users on these phones actually do is keep a handset that still works. TechRepublic notes that a phone can stay perfectly usable after its operating system stops receiving major upgrades, while apps and connected services raise their minimums around it ^[16]. 9to5Google's writer argues that the phones named in the Reddit reports offer experiences no longer available on most modern Android devices ^[13]. I think the story platform teams tell themselves about people below a version floor is that they never got around to updating. These look like people who chose to keep their phones. Auto is what they use behind the wheel, for navigation, calls, messages and media, in TechRepublic's list ^[15].

The two outlets split on what to do. "If you're an affected Android 9 Pie or Android 10 user and you need Android Auto support for your car, I would suggest starting to shop around for a replacement device running at least Android 11," 9to5Google's writer wrote ^[10]. Part of that case is price: the writer sees no obvious end to smartphone price hikes ^[14]. TechRepublic wrote that "Android 10 users do not need to replace their phones based on the warning alone" ^[11]. Its first step is checking whether the manufacturer still offers an update to Android 11 or later ^[12].

Both are right, for different phones. Sort each phone on two lines: whether its maker still offers Android 11, and whether the driver relies on Auto every day. A phone that can update needs software in either case, since TechRepublic notes an Android 10 device is not necessarily stuck there ^[12]. A phone that cannot update and rarely sees a car can wait for Google, as TechRepublic advises ^[11]. The one cell that justifies spending money before Google says anything is a phone stuck on Android 10 or 9 Pie, held by someone who drives with Auto daily. 9to5Google's shop-now advice fits that cell ^[10]. The tradeoff is that the notification could still be a bug, according to TechRepublic, in which case the early purchase was not needed to keep Auto ^[7].
