It is important to know

The most important factors when choosing a phone are comfort in everyday use and how long you plan to use it. Before buying, check whether the larger screen is suitable for one-handed use and what software support is available for this model.

• A larger screen can be handy for reading and viewing content, but it may not be the most comfortable if you often operate your phone with one hand.
• A lot of storage space is especially useful if you keep photos, videos, and apps directly on your phone; the actual need depends on your habits.
• The memory specs alone don't tell you how long your phone will receive updates. If you plan on using it for many years, check the support for that model before you buy.
