Problem with phone memory, full junk files
Hi everyone, i've a problem with my iphone, is an SE 2016 model, i've used this phone for almost 1 and an half year, the problem is that the memory is full of junk files, i have 32 GB of memory and 15 GB are occupied by "junk" files.
I've tried to contact the apple support but i can't because the phone is no longer in warranty, but the phone was purchased 1 and an half year ago. so it should be in warranty.
If i go into the settings menu<space> in the voice "other" there are 15 GB of files, cache, log and other things used by the system, if i go in the voice "system" there are 5 GB of files.
I want to remove system logs and cache because i can't use my phone anymore, i can't even use whats'app because i've no space left.
What can i do to remove these files?
I've tried different solutions, but nothing changed.
iPhone SE, iOS 13
