What makes a phone so unique? Everything else in own possession and home can be searched with a proper warrant.
Cops have gone through papers in file cabinets for at least a century. Closets, safes, the attic, they can dig in your yard, search in the house’s crawl space, and even the suspect’s anal cavity,
Computer forensics has been a big thing for a long time. The police have software that dumps out the log files, recent browser history, images etc. I recall testimony by the forensics cop during the Casey Anthony trial. Describing the software he used and Google searches members of the family had entered. The FBI lab can do even more detailed scans of the hard drive and cache.
Why bitch about them looking at content in a smart phone?
It’s bad enough that Apple refused to help in a National Security case. Protecting a terrorist. Thankfully the FBI found other means to crack that phone.
I don’t see any difference in a file cabinet with thousands of personal papers and a phone with documents and caller history. Its personal information that has limited protections. But if a judge oks a warrant then yes, the cops have a right to that information. imho
