Who supplied the phone to you @Hannah23 ?
Is your software up to date ?
Are your apps up to date ?
A Samsung Experience Store or Samsung Service Centre can look at the phone.
If needed you can clear the system cache files via turning the phone Off and then from a set series of button presses go into the phones system files and clear the cache.
And or go into Settings_Apps_Google Playstore_Storage_Clear Cache.
If needed also clear Data as a very last resort.
A final resort would be to back up and remove any relevant Sd card and factory reset.
