Ppi Samsung — Invalid
A recent Samsung One UI update might have introduced a bug in the display manager, causing the phone to miscalculate the scaling, resulting in images that appear stretched or text that is too small/blurry.
The "Invalid PPI" or DPI-related errors on Samsung Galaxy phones range from a minor app annoyance to a symptom of a catastrophic hardware failure. For most users, the solution lies in resetting display zoom or adjusting the "Minimum Width" in Developer Options back to its default value. When a malfunctioning app causes display cut-offs, clearing its data or changing its full-screen settings is usually effective.
You do not need to buy a new phone. You need to fix the density mismatch. Here is the technical hierarchy of solutions:

Summary Checklist Potential Cause Quick Fix Action Temporary software glitch Perform a forced hard reboot Corrupted network profiles Reset Network Settings in One UI Mismatched carrier configurations Reset APN settings to carrier defaults Dirty or malfunctioning SIM Clean and reseat the physical SIM card Outdated system protocols Install pending Samsung software updates Mismatched MDM profile Reach out to corporate IT admin to regenerate profile
