All models in the line Galaxy J have long lost official support. The reasons are standard for budget smartphones:

  • 📉 Outdated chipsets. Exynos 3470/7570 processors (in J2/J3) do not support new Google APIs.
  • 🌍 Regional features. In some countries (for example, India) updates took longer to come out than in Europe.

Latest security patch for most models Galaxy J was released in 2019–2020. This means that:
