My review of the S25 ultra
What i love the most about the s25 ultra is that the battery life is so good , I stayed on my phone for 6 hours and I was only at 50 % I also like the display and camera on it , the camera can literally zoom 100x and I could take a picture of the moon and it looks so much better better than my iPhone

Charging port issues
While the samsung s25 ultra is a fabulous phone I cant get over the constant pop up telling me that water or dust has been detected in my charging port.. yes I have checked and there is nothing in the charging port so im stuck having to use a wireless charger which is not ideal.

Thank you for this question, Popa.
We can confirm that we offer an extra cover insurance called Samsung Care+ (which must be activated up to six months after you have bought the device from other retailers) and which covers your product for both accidental damage and theft. However, it is not available to cover loss under any circumstances.
More information about this can be found on the Samsung UK website.
Hope this helps.
No, unfortunately theres no possiblity of placing microSD in SAMSUNG flagship AKA top of the range models. Hence the reason why more and more people are just switching to apple iphones.
