Hello, we are here to help.
Please make sure that all 3rd party apps updated, open GooglePlay tap options (Upper-left corner) > My apps & games > Update all.
If the issue encountered with many apps, please backup your data and perform a factory data reset.
Furthermore, you can bring the handset to the nearest service center to find the possibility to sort out the problem. https://www.samsung.com/ae/support/service-center/
Thank you :)
