One UI is one of the most feature-rich and polished Android skins around. It offers deep customization options and an interface that feels distinctly Samsung without straying too far from Google’s design principles. However, even after several generations, One UI still has a few annoyances that have remained unaddressed.After using One UI for years, there are three particular issues in One UI that I think Samsung needs to fix.1. Unreliable battery estimates and stuttery UI below 5% batteryOne of the most frustrating aspects of Galaxy phones is the dramatic drop in user experience when the battery level falls to 5% or below. The remaining battery often drops unpredictably; it sometimes nosedives from 5% straight to 1% or even causes the phone to suddenly shut down. This abrupt drop not only creates anxiety but also highlights inconsistent calibration in One UI’s battery level reporting.Moreover, the UI becomes noticeably laggy. Animations stutter, scrolling turns choppy, and even basic UI navigation feels extremely sluggish. Phones usually try to save power and performance when the battery is low, but Samsung’s implementation is quite aggressive and leaves users with a bitter experience.2. No simple app lock optionSamsung has been quite stubborn about adding a simple app lock feature in One UI, something even budget Android phones from Realme and Xiaomi have offered for years.Yes, there is Secure Folder, which encrypts apps and data under secure Knox protection. However, for users who just want to add a quick PIN or biometric lock to a specific app, Secure Folder is overkill. It requires setting up a separate profile, and installing apps requires a lot of time and effort.A simple ‘Lock' toggle within an app's App Shortcuts menu would make far more sense for the average user.3. Back gesture doesn’t work with Samsung KeyboardOn Samsung phones, the edge swipe gesture for back navigation becomes unresponsive when the Samsung Keyboard is active. This means you can’t quickly exit an app or return to the previous screen with a single swipe while the keyboard is open.Instead, you’re forced to minimize the keyboard first or use the back swipe gesture above it. While this might seem minor, it disrupts muscle memory and makes the UI feel less fluid.As Samsung continues to position One UI as the most polished Android experience and an advantage of buying a Galaxy phone or tablet over competing devices, addressing these small but annoying issues could uphold One UI's reputation.The post Samsung still hasn’t fixed three annoying One UI issues appeared first on SamMobile.
