Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.

Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM. I have had this slate for long enough I am not even sure how much I paid for it, but bought it usedInformation about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen. One of the main characteristics of the display is its type/technology, on which depends its performance. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC

The only issue is that the version of android is aging and there does not appear to be an update for it. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Widthit loses a few points for having a glossy screen, which tends to reflect unwanted light, hence matte finish screens are generally better. Where battery life is concerned: To make your battery last as long as possible is to be sure to turn off BLUETOOTH AND WIFI when you do not need these. Both are these are memory hogs! Also, I turn off my GPS and even SYNC sometimes to conserve battery and then turn them on later. that is, or may reasonably be considered to be, defamatory, libelous, hateful, racially or religiously biased or offensive, unlawfully threatening or unlawfully harassing to any person or entity; Information about the manufacturer and model of the image sensor used by this camera of the device.

The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.Brightness of the screen: I compared this with my older ASUS MeMopad and found that this screen is MUCH BRIGHTER! (I like a bright and vivid screen and this tablet has just what I was searching for in a screen). Galaxy Tab 4 10.1 was released with Android 4.4.2 KitKat. Samsung customized the interface with its TouchWiz UX software. Some devices only run up to Android 5.0.2 as opposed to the 5.1.1 version. It also has apps from Google, including Google Play, Gmail and YouTube, it has access to Samsung apps such as ChatON, S Suggest, S Voice, S Translator, S Planner, Smart Remote (Peel)(WiFi Version Only), Smart Stay, Multi-Window, Group Play, and All Share Play. A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.

but that is a minor annoyance. I have added apps from google play and they work fine, even old ones that are themselves outdated apparently. So I assume in its previous life it did have a cell phone circuit and was on ATT somehow. That part is irrelevant; I used the local apps and frequently connect it to wi-fi signals at home and lots of other places. never had a problem with it. Speed of this unit / Memory etc - This tablet has adequate memory and I found it enough to keep the tablet running at a good speed. And I found that the tablet runs plenty fast with no lagging. If it runs out of battery, you just recharge it thru micro-USB and it reboots. If profoundly discharged, you do not even get a "charge" indicator from the boot ROMs until reaching about 3 percent. otherwise no harm done. that violates any law, statute, ordinance or regulation (including, but not limited to, those governing export control, consumer protection, unfair competition, anti-discrimination or false advertising); Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications. Information about additional software and hardware features of the rear camera which improve its overall performance. For years, I have owned Samsung Tablets and phones and love the quality and features. This is my favorite Samsung tablet yet! So far I have had a truly WOW experience using this tablet as it has exceeded my expectations! Below are the Pros and the Cons of this tablet...In late July, 2015, the tablet updated to Lollipop and it saves me battery, love this update. Clarity of the screen for reading - It is very easy to read Kindle books and eBooks on this tablet. And I place the tablet inside my case/stand and read in landscape, it is very easy to read on it this way. The tablet just sits in my lap for easy reading.
