restored firmware via itunes. after installing new ios (i didn't restore backup , os clean) opening application homescreen (anything, safari , setting) takes 10-15 seconds launch!!! however, if run them in siri suggested apss, open immediately!!!!!!!!!!!

after opening seem work normally! re-opening them(even pressing home button , re-open app) same :(


problem is, everywhere when change toggle (for example turning wifi on or off, turning icloud on or off, , green toggle in setting or third party apps) take 20 seconds react!!!!!!:mad:
