Transsion’s XOS mobile interface ships with a suite of built-in privacy controls aimed at preventing bystanders from reading users’ screens in public.
The feature set, called Peek Privacy, is native to XOS — the Android-based operating system Transsion installs on its Tecno, Infinix, and itel handsets, which sell primarily across Africa, South Asia, and Southeast Asia.
What Peek Privacy Does
The tools work by detecting when a second face enters the phone’s front camera field of view. When the system identifies an additional observer, it can blur the screen, dim it, or trigger a lock — depending on the user’s configuration.
A separate angle-restriction mode narrows the screen’s visible range, making content harder to read from the side without alerting the user.
Both functions run locally on the device. Transsion has not disclosed which chipsets or sensor configurations are required for full functionality.
The Shoulder-Surfing Problem
Screen snooping — often called shoulder-surfing — is a documented security threat in shared and crowded spaces. researchers at the University of Glasgow published findings in 2023 showing that thermal imaging cameras could reconstruct PINs entered on smartphone screens up to one minute after input, illustrating how exposed mobile interactions are in public environments.
Shoulder-surfing extends beyond PINs. Bank transfers, private messages, and health data all pass through phone screens in transit, queues, and shared offices.
Transsion’s Market Position
Transsion ranked as the fourth-largest global smartphone vendor by shipment volume in Q1 2025, according to International Data Corporation. The company shipped approximately 28.8 million units in that quarter, trailing Samsung, Apple, and Xiaomi.
Its devices sit at the budget end of the market, typically retailing below $200. That positioning puts them in the hands of users who are less likely to purchase third-party privacy screen protectors or supplementary security software.
XOS differentiates Transsion handsets in a segment where hardware specifications among competitors are often nearly identical.
Android’s Native Privacy Tools
Stock Android does not include a built-in face-detection screen-blur feature. Google’s operating system offers a range of lock screen and notification-hiding options, but none that react in real time to a detected second viewer.
Samsung’s One UI and some other Android skins include similar “Private Share” or content-restriction tools, though face-detection-triggered blurring remains relatively uncommon outside XOS at the consumer price point Transsion targets.
Google has not announced plans to add comparable functionality to Android’s core feature set.
Background
Transsion Holdings listed on China’s STAR Market in 2019. The company’s three main brands — Tecno, Infinix, and itel — each target distinct price tiers within the budget segment.
IDC data shows Transsion has grown its global share steadily since 2021, driven largely by volume in sub-Saharan Africa, where it holds the top market position by units shipped.
