Storage error

Good afternoon,

Sorry for my English

I am from Ukraine (it is Ukrainian language on screenshots)

I have an iPhone 11 64 GB

I bought it in retail Apple Store last year, which is located in Philadelphia, PA.

The main problem is that every day I have an error that it is not enough storage on my iPhone, it is full.

I have already deleted a lot of important information from my device.

I have cleaned a cache

And still there is a lot of trash in the section “Other”, (as you can see on the screen shot total is 5,61 GB)

I don’t understand what is going on

I don’t want restore my iPhone and set up it as a “new iPhone” without restoring it from reservation data copy.

When try to delete some photos and videos, sometimes it doesn't work.

Some times it works, but only for a couple of days. Then the storage section "Other" grow, and free storage is not available.

I have lost a lot on information.

iPhone occured an error and sudenly deleted some data history on different messengers.

Why I pay 750$ for this product and have such a big problem?

What is the solution?

I have a receipt, original box

Also I can provide you an IMEI an SN.
