Readers often want to know how they can check the specification of their phone or tablet in Android Jelly Bean. By far the easiest way to do this is to check the spec sheet on the manufacturer's website, but if this information isn't easily available it's also possible to work out the specification yourself. Here's how. See Android Advisor.
How to check the spec in Android Jelly Bean
Step 1. First, there are several specifications you can check from the About phone or About tablet option in Jelly Bean's Settings menu.Open Settings, then scroll down to About phone or About tablet, depending on your device. From here you can see the model name of your phone or tablet, plus which version of Android it's running.
Step 2. Tap Status and you can also find your Jelly Bean device's serial number and IP address, and check the remaining battery capacity.
Step 3. It's possible to work out the storage capacity of your phone or tablet from Settings, Storage. As you can see on our 16GB Nexus 10, Jelly Bean reports 13.05GB total space. (The Jelly Bean system files consume the remaining 2.95GB.) Below this is the Available storage, which is what's left after any apps and media you've added.
Step 4. Also in the Settings menu, under Wireless and Networks, More, you can see whether your Jelly Bean phone or tablet supports near-field communication (NFC), aka Android Beam.
Step 5. Lastly, you can check the phone or tablet's camera resolution (for stills and video) by launching the Camera app, opening the Settings menu within, then seeing what is the highest resolution available.
Step 6. Of course, all this is a bit long-winded, and there may still be some specifications you want to check and can't within Jelly Bean itself. Notably, you can't immediately tell what processor your phone or tablet runs, nor check its screen resolution. The Geekbench 2 app we use for benchmarking purposes reports on the tablet name, operating system, processor and RAM. For example, we can see the Nexus 10 runs a 1.7GHz processor and Geekbench 2 has found 1.23GB of installed RAM.
Step 7. Geekbench 2 isn't free, however, and for most users it won't warrant the purchase. After all, checking the performance of your Jelly Bean phone or tablet after you've purchased it will only upset you if it isn't as fast as you'd hoped. It's the real-world experience that counts in any case, which isn't something on which Geekbench can report. Instead, there are several free system information apps in Google Play, such as Electric Sheep's Android System Info. Find and download such an app.
Step 8. Taking Android System Info as an example, five tabs offer a dashboard, system information, a task manager, an app manager and an activity log. The main Dashboard reveals at a glance the amount of internal storage and RAM, plus useful information such as the remaining battery capacity, uptime, network type and IP address.
Step 9. Open the System tab to reveal more detailed information. Specifications are listed here under logical headings, so simply find the one you're looking for and click the plus icon beside it to view more information. Under Screen, for example, we can see that the Nexus 10 has a 60Hz refresh rate and a 2560x1504 resolution, with a 320dpi pixel density.
