I have lost my phone and someone bypass my phone and data is removed. now i found my phone back but not data, is there any way to recover my data.???

Did you not have it backed up?

At this point, I would suggest that you totally erase your phone to remove any data from it that might have been added after you lost it. Go to settings, general, reset, erase all content and settings and then set it up as a new phone and reload the last backup you had. Just curious how your data got erased after you lost your phone. Did you have it locked with a passcode and have 2 factor authentication set up?
