Which Apps are behaving like this?
Can you try closing down any open apps to clear up ram on your device?
Can you clear your caches?
How much internal storage do you have left? If storage is running low, this can cause your running applications to glitch.
Were the apps obtained from the official Google play store?
Van you try deleting the most recent app you've downloaded to see if it's a rogue?
A last resort would be to back up and factory reset.
If you're still experiencing issues with your handset having completed the steps above, you can choose to send your handset to our designated repair centre Fónfix where our engineers can test your handset and carry out any necessary repairs. For more information on this, please see the following link. Please note that if your handset was purchased more than 24 months ago, your manufacturer’s warranty agreement would no longer be valid which would mean that you will be liable for the cost of repair.
