What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the operating system is written as “Andriod 16”, while the manufacturer information ties iOS transfer availability to Android 17 or later and One UI 9 or later. Expandable storage is described as up to 128 GB in product details but up to 2 TB in manufacturer information. The listing gives dimensions as 16.4 x 7.8 x 0.8 centimetres, while promotional copy calls the frame 7.7mm. Verify the selected model’s software, microSD limit and physical measurements before purchase. The listed water resistance is not permanent, and the manufacturer says the phone is not recommended for beach or pool use.
