You read a figure, switch to notes and return to the document because you have forgotten it. On a Galaxy supporting Multi window, keeping two apps visible can be worth trying. Split screen and pop-up view suit different workflows. The useful question is not how many windows you can open, but whether the layout makes reading, entering and checking information easier.
1. Pick a layout for the task, not the window count
A stable split layout may suit reading a sample document and entering matching notes. A small calculator window may be more convenient for a single calculation before returning to reading. These are workflow suggestions, not rules that every application must follow.
Start with non-private sample content. Check whether text remains readable, the keyboard hides something important or smaller controls cause mistaken taps. Returning to one full-screen app at a time may be more effective than keeping a multitasking layout that needs constant rearrangement.
2. Try split screen from the recent-apps menu
Samsung's Multi window guide describes opening Recents, tapping an app's icon, selecting Open in split screen view and choosing the second app. Navigation and labels vary by device and software. Samsung notes that some apps do not support split screen.
Try a simple pair you already use, such as a browser and notes when supported. Keep the sample short enough to read and enter in one pass. A missing option in one application does not itself establish insufficient RAM or a display fault; record the application and test another pair before changing multiple settings.
3. Use a pop-up for a shorter secondary task
Samsung also describes Open in pop-up view from the recent-app icon. Its Galaxy window-layout instructions explain moving and resizing the window. Inspect your device's controls for minimizing, expanding and closing it rather than expecting every interface to look identical.
Place the secondary window away from the figures and buttons you need underneath. Enter a sample line and review the main document again. If every input needs another window move, reconsider the layout. Minimize or close the secondary task when finished instead of leaving several layers over the main content throughout the session.
4. Adjust the reading area and test with the keyboard open
Samsung explains resizing split-screen areas with the divider. After adjusting it, check that the information you need remains visible. Giving a reading app more space may help, but repeat the test while the keyboard is on screen rather than judging an empty layout.
Use a small exercise: read three entries, type three notes and compare them. Check mistaken taps and comfort when holding the phone. Long documents or dense tables may still suit a tablet or laptop better. Opening two applications does not automatically make a phone the right workspace for every task.
5. Inspect a used Galaxy with your intended app pair
Try the exact device with software you are allowed to use and fictional information. You do not need a confidential work-account login to inspect the layout. Buying a different model may not remove an application's own window limitations, so test compatibility before choosing from a general multitasking claim.

Conclusion
Try split screen for continuous comparison and a pop-up for a brief secondary task. A good layout makes the actual applications easier to read and use. Test one small workflow before making multitasking your main reason to replace a phone.
