Dear Minh,
I just bought a new phone and wanted to show it off to you! I spent a lot of time researching and finally decided to choose Samsung Galaxy S23 Ultra. I use my phone to do everything, from taking photos, playing games, watching movies, to surfing the web and working. Galaxy S23 Ultra meets all my needs with a large 6.8 inch screen, 108MP camera that takes beautiful photos, powerful Snapdragon 8 Gen 2 chip and 5000mAh battery for all-day use. The phone has 12GB of RAM and 256GB of storage, enough for me to store all my favorite photos, videos, and apps. Its price is quite high, about 30 million VND, but I think it's worth it for the features it brings. I am very satisfied with this new phone and believe that it will accompany me for many years to come. You can come to the store to try it out!
Love,
[Tên của bạn]
