Hello @da9kl 

There could be a number of reasons why a phone shows signs of connection issues. 

• The area your in has network issues, and or network congestion issues. Check any available online network checkers. 
• The phone needs a reboot by turning it Off and On. 
• The sim card isn't seated properly. 
• The sim card is at fault. { A Network can perform a sim swap to replace the sim }
• The phone needs the connection refreshing via Settings > General Management > Reset > Reset Network Connections > Reboot the phone. 
• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode.
