Flight Mode
This phone is an absolute beast in performance and features, but I have one frustrating issue: whenever I turn flight mode on or off, the process takes far too long and slows down my experience.

Memory, sound, video & phone size is brilliant.
I bought this a few weeks ago on a great deal. Brilliant phone I love it. The size is great for watching videos and the camera is so good. The memory it can hold is awesome, you don't have to worry about deleting things and running out of space. The sound quality is really good, especially for videos and music. Highly recommended.

camera, battery, and performance
[This review was collected as part of a promotion.] The S25 ultra is a compelling phone, with its performance and its slick, simplistic design, and its Jetblack colour in the sun. Its display is bright and able to be seen in the sun. The camera has amazed me with its photographs, while the battery lasts for 2 days straight on heavy use. thanks to, Samsung for making this phone I would not have this experience.
