iPhone storage trouble
On my iPhone 7 32gb my storage is full. 5,4gb are used by the system and 16,4gb by a voice called “Other”. In the last week to be able to continue to use my iPhone, I’ve deleted many apps, but at the moment all the few apps I have are really important, but I can’t keep them because of storage. As you can see In the picture I don’t have so many things I can delete. How can I reduce storage used by the voice “Other”?
Thanks for your help.
