Are your apps up to date @Mammoo
Try putting the phone in Safe Mode which disables any downloaded apps and leaves the stock ones working and then see what happens. If things return to normal then one or more of your apps are not optimised. Come out of Safe Mode and start deleting your most recent apps one at a time until it stops.
If a phone glitches still after a few days from the update and still in Safe Mode then I'd suggest to turn the phone Off and then from a set series of button presses go into the phones system files and clear the cache. No info is lost this way.
If that does not help then back up and remove any relevant Sd card and factory reset as a last resort.
