You can always get the “night light” feature via an app that uses GL shaders, but the fingerprint swipe is probably out of reach for the Nexus 6P and the Nexus 5X. For the Night Light, Lake says that “uses a new hardware composer interface to do color transforms on the display hardware rather than using a GL Shader, which unfortunately means it requires driver support that is not present on Nexus devices.” There’s probably a special sensor on the fingerprint scanning module that allows this feature on the Pixel. The fingerprint swipe, we can understand. Ian Lake says that both features require specific hardware on the Pixel that is not available on the Nexus 6P and 5X. The Night Light feature is similar to what other apps like Twilight and F.lux do – it reduces the blue light emission of your screen to help you fall asleep better. This prevents you from doing finger gymnastics to reach the status bar at the top of your screens. The fingerprint swipe is available after you unlock the phone with your fingerprint – you can swipe down on the scanner from any screen to see your notifications. The fingerprint scanner is still traditionally where the Nexus phones have put it – a round dent/dimple at the back. The company also recommends that the OnePlus 6T fingerprint sensor should only be used with official or approved screen protectors, using Face Unlock with the sensor, and also ensuring everything is kept clean.I’m sure most of you are familiar with the Google Pixel’s hardware and layout by now. That includes registering the fingerprint in a dark, neutral temperature room. OnePlus also offers a few tips to improve the reliability of Screen Unlock. By adding to the data set, accuracy can be further improved. Screen Unlock works from a hardware perspective by shining a light source through the OLED display and matching the fingerprint with the data set secured within the Snapdragon 845 platform. The Samsung Galaxy Note 20 and Galaxy Note 20 Ultra (stylized and marketed as Samsung Galaxy Note20 and Galaxy Note20 Ultra) are Android-based phablets designed, developed, produced, and marketed by Samsung Electronics for their Samsung Galaxy Note series, succeeding the Samsung Galaxy Note 10 series. That should help improve accuracy over time, but it probably won’t make much of a difference in terms of speed. I was happy with my Nexus 5X until it fell victim to the apparently-common bootloop hardware fault while I was on holiday and I bought some Huawei. In short, the software automatically registers new bits of the fingerprint that it originally missed every time you successfully log in to your device. In these cases, once the phone is successfully unlocked, the algorithms add this new fingerprint data to the existing data to improve unlock speeds under these conditions in the future. The sensor’s algorithms are also able to figure out when the user’s fingerprint is different than usual – if their finger is wet or if they have a cut on it, etc. This means that over time, the phone will unlock even faster. So, every time the in-display fingerprint sensor is used, it gathers more data about the user’s fingerprint. This fingerprint data is then added to the data the phone already holds, making it more complete. Yale Liu, a software engineer at OnePlus, explains:Įvery time a user successfully unlocks the phone with their fingerprint, the sensor also records areas of the finger that weren’t registered in the initial fingerprint setup stage. Further, OnePlus has built its Screen Unlock feature to improve over time. Now, with the debut of the OnePlus 6T, the company has finally gotten that fingerprint sensor ready for all users. In previous posts, the company has mentioned that the OnePlus 5T was considered for the technology, but it wasn’t up to par with their standards yet. OnePlus has been working on bringing an in-display fingerprint sensor to its devices for a long time. The OnePlus 6T was one of the first “mainstream” devices to offer that functionality, and this week the company is explaining how the functionality gets better over time. In-display fingerprint sensors, for better or for worse, are going to be the next big thing in Android smartphones.
