Majority of apps disappeared

A couple of days after installing the beta, iPhone 7 Plus started strangely deleting apps. After a while only a handful were left. Of the default apps only notes was left. Safari, settings, phone... are all gone.


I am on holiday trip without a laptop (or access to Apple care). Is there any way to get the phone working without computer/iTunes?


THanks for your help in advance!
