Are you only experiencing these symptoms with Snapchat?
Have you tried clearing the cache of your snap chat application and restarting your device?
Thank you for confirming. If the issue continues and troubleshooting is not beneficial, and this is the only app this occurs with, you will need to reach out to Snapchat for additional support.
my note 10+ also has this issue. I've cleared cache, I've factory reset phone, ive restarted, deleted and reinstalled, and cleared all snaps memory from my phone but it still has these issues 3-4 times a day
