PERFORMANCE. We evaluate how fast a tablet can perform calculations and see how long it takes to complete different tasks. The Lenovo Tab M7 is slower than most other tested tablets and has speeds acceptable for running everyday tasks, such as web browsing or email. Copying a set of files was very fast.
DISPLAY. We also score the attributes of a tablet's display. This device has a display resolution of 1024 x 600, and produces very coarse detail at 171 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 undersaturated for colors with a narrow viewing angle. Viewing angles are very narrow and not ideal for sharing the screen; a single viewer will have limited positions for getting optimal display.
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 only display one app at a time on this tablet, so multi-tasking will be more difficult with less information on the screen.
