Motorola Moto Z and Moto G4 will get security updates, but probably not monthly
Motorola today issued a statement regarding security updates for its Moto Z family of smartphones (including the Moto Z, Moto Z Force, Moto Z Droid Edition, and Moto Z Force Droid Edition). Last week, we told you that the Moto Z would receive monthly security updates, but it looks like these won't actually be monthly.
According to Ars Techinca, Motorola stated that "it's difficult" to roll out software security updates on a monthly basis for all its handsets, and it's more convenient to include them in OS upgrades, or in scheduled maintenance releases. While Motorola assures us that the Moto Z, as well as the Moto G4 series (recently launched in the US), will receive security updates, it simply can't commit to delivering them month by month. Well, we can't say we're surprised: ever since Google started its monthly Android security update program last year, Motorola constantly failed to be on time with these updates.
