It is important to know

When choosing, pay attention to the size of the phone and how you will hold and use it most often. A lot of space for files is useful, but in itself it says nothing about the quality of photos or video recording.

• If you keep a lot of apps and files on your phone, a large capacity can reduce the need to constantly delete content.
• The larger format may be less convenient when used with one hand; consider whether this type of operation suits you before purchasing.

In practice

🟢 Many locally stored files

Suitable – a large capacity is useful if you want to have a larger collection of apps, photos, or other files on your phone.

🟡 One-handed use

Suitable with limitations - the larger format can be less convenient to operate with one hand, so how you usually hold the phone is important.

Answers to frequently asked questions

Does large storage capacity also mean better photo quality?

No. It only tells you how much space is available for files; it doesn't tell you anything about the quality of your photos or videos.
