Owners of the new Galaxy S10 and S10 + phones actively complain on the forums about the problem of random touches to curved ones
Edge Touch app
In the official Galaxy store (Galaxy Store)You can find the native application Edge Touch, which will help turn off parts of the screen with curved edges to protect against accidental touches. This application will work not only with the new Galaxy S10, but also on the Galaxy S7, Galaxy S8, Galaxy S9, Galaxy Note 8 and Galaxy Note 9. At the same time, your phone must have Android 8 Oreo or Android 9 Pie.
How does this application work? It allows users to create locked zones that prevent unintended touches on the screen. Capture zones are also customizable; These are areas where content on a curved display will not be affected when the phone is held. The former are shown in the application as yellow areas, and the latter are marked in green. One of the users unsubscribed on the forum that the application Edge Touch "completely solved" the problems he encountered with random touches.
First you need to configure inportrait mode, and then turn the phone to a horizontal position and again perform the process of setting up locked zones and capture zones. If you prefer not to waste time on adjusting the display of your phone, the application has an optimized default setting that you can use immediately after installation.
