What it means now that support ends
- 🔓 Security risk grows monthly. New vulnerabilities are discovered constantly; on an unsupported phone they are never fixed. Banking, payments, email, and password apps become progressively riskier.
- 📱 Apps drop off. Developers raise their minimum OS requirements over time — first you lose updates to apps, then the apps themselves.
- 💸 Resale value falls fast.The market prices support: once a phone leaves a manufacturer's update list, its used value drops sharply and keeps falling.
