PERFORMANCE. We evaluate how fast a tablet can perform calculations and see how long it takes to complete different tasks. The Lenovo Tab 4 10 (TB-X304F) (16GB) is slower than most other tested tablets and has fair speeds when running everyday tasks, such as web browsing or email. The time to turn on and load the OS was faster than most, although this will be affected by what apps are installed on your tablet. Copying a set of files was fast.
DISPLAY. We also score the attributes of a tablet's display. This device has a display resolution of 1280 x 800, and produces very coarse detail at 151 pixels per inch. The very bright screen and its reduced glare will be easy to view when used outdoors or in bright rooms. Testers found the display quality is dull under mid lit conditions and washes out under bright light. Viewing angles are middling, so you may need to adjust the screen to get an optimal display for a single viewer, but moreso for multiple viewers.
CONVENIENCE. To gauge a tablet's ease of use, we look at the intuitiveness of its controls, as well as how quickly it takes to perform common tasks, such as connecting to a WiFi router or transferring files. The on-screen keyboard had a more comfortable size than on other tablets, and buttons were intuitively placed or easy to use. The touchscreen accurately interpreted touch gestures and it showed little, if any, lag in response. This tablet's initial setup process was quick and simple to personalize. It was fast in connecting to a wireless network. There were few, if any, issues when transferring files to and from different computers or storage solutions. You can display two apps at once on this tablet, making it easier to multi-task and view more information on the screen.
