Indeed, there are some apps that will come handy for anyone. Firstly, I want to recommend you the "One Hand Operation +" application downloadable from Galaxy Store for free. This app is suitable for the easy interaction with your phone's features, especially the multitasking after it became a long process with the latest UI update. You can simply open apps or use commands by swiping at 3 different directions from the each edge of your screen (up, center, down). The second app that I use most is "Secure VPN", and again easy to use whenever you need. For the third and last third party app that I mostly use is "Holey Light". As there is no led indicator on the S10 versions, this app uses the led around the punch hole camera. It is so useful to have whenever you cannot reach to your phone. In addition it includes cool animations too. I hope these have helped!
