| 1 | Select the Right Screen Size | Display diagonal and device weight | Approximately 8–10.1 inches for mobile field work; choose a smaller display when one-handed operation is essential. | Confirm that maps, forms, barcode interfaces, and maintenance documents are readable without excessive scrolling. Check whether the tablet can be carried comfortably for extended periods. | Balances viewing area, portability, and operator fatigue. |
| 2 | Check Resolution and Viewing Clarity | Resolution, pixel density, contrast, and viewing angles | At least 1920 × 1200 pixels is a practical baseline for detailed text, images, and technical drawings. | Open small text, high-detail images, and split-screen applications. View the display from different angles and verify that colors and text remain clear. | Reduces eye strain and improves accuracy when reviewing field data. |
| 3 | Verify Outdoor Visibility | Brightness, anti-glare treatment, and reflectivity | Around 500 nits or more for general outdoor use; approximately 800 nits or more is preferable for bright sunlight. | Test the tablet outdoors or under strong indoor lighting. Check whether glare, fingerprints, or direct sunlight make text and controls difficult to see. | Maintains readability during inspections, transport, construction, and utility work. |
| 4 | Test Touch Response | Touch latency, accuracy, multi-touch, and glove operation | Touch feedback should feel immediate, with accurate response at screen edges and reliable operation with commonly used work gloves. | Use gloves, a dry finger, and a damp finger to operate menus, keyboards, zoom controls, and signature fields. Test repeated taps and small on-screen buttons. | Prevents input errors and reduces the need to remove protective gloves. |
| 5 | Assess Physical Durability | Ingress protection, drop resistance, and operating temperature | Consider an IP65 or higher rating for dust and water protection, plus documented drop testing and a suitable operating temperature range for the worksite. | Review independent test documentation and inspect port covers, corner protection, screen protection, and enclosure seams. Match the specifications to the actual environment. | Lowers downtime caused by dust, rain, accidental drops, and temperature changes. |
| 6 | Evaluate Battery and Charging | Battery capacity, runtime, charging speed, and replaceability | Target a full working shift under realistic use, typically about 8 hours or more, rather than relying only on standby estimates. | Run navigation, wireless data transfer, camera scanning, and screen-on tasks at normal brightness. Check whether spare batteries, vehicle charging, or docking options are available. | Supports uninterrupted field operations and simplifies shift handovers. |
| 7 | Confirm Overall Usability and Connectivity | Operating system support, ergonomics, wireless connections, and accessories | Choose a supported Android version with a clear security-update policy, dual-band Wi-Fi, Bluetooth, and optional cellular or positioning features when required. | Test application compatibility, boot time, physical buttons, carrying handles, camera access, GPS accuracy, Wi-Fi roaming, and compatibility with docks, scanners, and vehicle mounts. | Improves workflow efficiency and reduces integration problems after deployment. |
