Discover every last detail about your Android device, from its serial number and screen resolution to sensors, storage and system specifications. All this information and more is displayed instantly and accurately, without the need to run scans. A couple of the categories – such as Storage and Camera – do require an extra tap or a moment’s delay before data is displayed, but it really is a moment. My Device can’t do anything to change or improve the data – for example, it won’t offer to free up storage space – and you can’t export the info, either. But our main real grumble is the adverts that fill the screen unless you pay 89p for an in-app upgrade. Despite that, we reckon My Device deserves five stars – it’s a gem.
