Two reasons
1. Maybe another language been added before

2. Previous owner did root the device

Solutions

1 . Delete system cache through recovery mode

2. A full reset will definitely help

3 . Connect to pc using smart switch and check for updates

4. Take out Sim card and set airplane mode on then restart

Anyway. Backup any important data first
