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. One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions. I have had this slate for long enough I am not even sure how much I paid for it, but bought it used 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.

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. 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 I have added apps from google play and they work fine, even old ones that are themselves outdated apparently.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. 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. 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.

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. it loses a few points for having a glossy screen, which tends to reflect unwanted light, hence matte finish screens are generally better. 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).

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. OTG USB Compatible - This tablet comes with a free OTG On the Go adapter cable. Just plug in your flash drive and you can copy files to the flash drive so easily or view files that are on the flash drive. *Note that portable external hard drives and portable DVD/CD drives will not work using OTG in this tablet because they require a lot of power. Battery Life- Very good to excellent. Since I have done a few tweaks on this tablet, now I have found that my battery life is better than the first and even the second day. In fact, the battery life now I find that when I use WiFi just when I need it, I now get about 7 to 8 hours with it(this reflects 100 percent brightness however). 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.

Information 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.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. 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. 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. CPU is the Central Processing Unit or the processor of a mobile device.

The only issue is that the version of android is aging and there does not appear to be an update for it. 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. Screen Resolution/Weight/Size etc - The first thing I noticed is that this tablet has 149 PPI-Pixels----however, what I discovered is that the screen is very, very clear and the colors are spectacular!

Note that this was one of the deciding factors that sold me on this tablet. I installed a SanDisk 32GB SD card and it works great on this tablet. My true star rating is 4.6 stars as I find that this tablet, for the most part, has exceeded my expectations. I did take a small amount of the stars off because sometimes the temperature rises a bit when I install several apps, play games, etc. The Samsung Galaxy Tab 4 10.1 is a 10.1-inch Android-based tablet computer produced and marketed by Samsung Electronics.
