It is important to know

When choosing, it makes sense to weigh the robust design and practical memory configuration against the way you will use it. If you are buying a phone for several years, also pay attention to the duration of software support, as it cannot be inferred from other features.

• The memory configuration is well-matched to using multiple apps and storing content, but it doesn't by itself tell you how the phone will perform with demanding games or intensive multitasking.
• For longer-term use, check how long the manufacturer provides system and security updates before purchasing.
