Android Phones & Tablet Q&A's by solomonsojay(m): 12:19pm On May 25, 2013 |
Here's to Address all questions n enquiries u have about any thing on phones and tablet on aandroid platform...let keep the questions rolling... Buh first let's use this as a standard for all android base phones and tablet....PLS. TAKE HAVD A PEN & NOTE IN UR JOT ER SO YOU CAN REFER TO IT IN FUTURE SO U WON'T ASK 1 ? 2TIMES. So far, I have reviewed quite a few Android tablets and received overwhelming response. Choosing the a tablet with the best price to performance ratio is not an easy task even with detailed reviews at hand. I have decided to write a guide that will help you to choose the best Android tablet or phone. without risk of over simplification, we can safely assume that an Android tablet or phone has the following critical subsystems 1. Processors (CPU + GPU) 2. User Interface (Touch screen and buttons) 3. Memory (RAM, ROM, NAND, External Storage) 4. Communications (WiFi, Bluetooth, phone) 5. Ports and interface (USB, HDMI) 6. Sensors and location (Accelerometer, GPS) 7. Power (Battery, voltage control, charger interface) 8. Casing (the case that holds everything) All of these systems need work together in harmony to give you a great Android experience. Let us start with the processor. 1. Processors (CPU + GPU) Android tablets and phones normally run on CPUâ €™s based on ARM architecture and are SOC or system on a chip. A SOC is an integrated circuit that integrates all components of a computer or other electronic systems into a single chip (from Wikipedia). A typical SOC inside an Android tablet or phone has a. The CPU b. The GPU (graphics processing unit) c. The VPU (vector processing unit) d. L1 and L2 cache e. RAM Interface f. Video coding and decoding engines g. HDMI interface Some SOCs like Qualcomm MSM7227T also contain modem processor and cell phone network connectivity modules. What to look for in the CPU? Ideally you should look for a SOC with the highest clock speed. The CPU component of the SOC is used to measure the clock speed. For example, if I am asked to choose between two devices, one with 800 MHz CPU and another with a 1000 MHz CPU, I will choose the higher one. But things get a bit complicated with multi core CPU. If I have to choose between a 1 GHz dual core CPU and a single core 1.5 GHz CPU, I will choose the 1 GHz dual core CPU. By the way, there are NO CPU for tablets or phones with 3 cores. So the advertisements you see for Mercury mTAB or any other tablet that claims “3 core†CPU’s are false and misleading. These companies are clubbing the CPU +GPU+VPU inside the SOC to claim multi-core CPUs. Any CPU below Cortex A9 is single core. arm-processors Here are some CPU you will find 1. Qualcomm MSM7XXX family (MSM7227T, MSM7627T) 2. Telechip TCC family (TCC8803, TCC 8902) 3. Rockchip family (RK28XX, RK29XX) 4. Samsung (S5PV210, Exynos) 5. VIA Wondermedia family (WM86XX, WM85XX) 6. Amlogic family (AM8XXX) 7. Freescale family (iMX5xxx) 8. TI OMAP family 9. Nvidia Tegra family 10. Vimicro family (VCxxx) 11. Allwinner 12. Ingenic family (XBurst) 13. Renesas family After extensive benchmarking with Quadrant, Linpack, GL Benchmark the knowledgeable folks at XDA, Slatedroid and few other forums have found that the best CPU for android-games For 2D Games and graphics (by best scores) 1. Samsung S5pv210 2. AmLogic AML 8726 3. Tegra 2 and TI OMAP For 3D games and graphics (by best scores) 1. Samsung S5pv210 and Tegra 2 2. Rockchip RK29XX 3. AM Logic AML-8726 For optimum battery life (by best scores) 1. Renesas EV2 2. Tegra 2 3. Samsung S5PV210 and RK29XX **The benchmarks were run on tablets running Android 2.3 From the ranking above it is clear that Samsung S5PV210 is the best all round CPU available in the market. 2. User Interface touchscreen The screen is the most interacted and visible part of a tablet or phone. If the screen is not good, it does not matter if the tablet or phone has the most cutting edge fastest CPU on the planet, it will still suck and you will be frustrated enough to pull some crazy violent acts on it. In brief, having a high quality , responsive screen is a must. Touch screen Tablets and phones come with two types of touch screens 1. Resistive 2. Capacitive The resistive screens are cheap and have single point of touch. They are not very responsive and you have to use a stylus to interact with it. In two words , avoid it. Capacitive also known as multi touch screen are the ones where you can use multiple fingers to interact with the device. They are smooth and responsive and you can pinch and zoom and use your fingers to swipe and do other cool things on the screen. Not all capacitive screens are made equal, a lot depends upon the LCD, the chipsets and sensors used to make the panel. Capacitive screens can be divided in to 1. 2 finger touch 2. 3 finger touch 4. 5 finger touch 5. 10 finger touch Ideally you should go for tablets with screens that support 3 finger touch or more. The screen and onscreen graphics should move smoothly when you swipe across them, photos should pinch and zoom smoothly when you interact with them, if they do not, I suggest you look for other tablets. Resolution The higher the better, a 7 inch screen with 1024×600 is better than a 7 inch screen with 800×480. But higher resolution also means tiny icons, buttons and graphics. High resolution is good when you have to read a lot of texts on web pages and you like your texts to be ultra crisps. Higher resolution also means slightly slower performance and more memory consumption. Look for 800×480, 800×600 and 1024×600 resolutions in 7 and 8 inch tabs. For 9 and 10 inch tabs the minimum you should expect is 1024×600. PPI PPI stands for pixels per inch, the higher the better. Do not settle for anything less than 144 PPI. Buttons The hardware buttons comes in two varieties 1. feather touch buttons 2. hard buttons. If your tablet has hard buttons, make sure they are sturdy. You have to touch them and press them a few times to check the quality. Viewing angle The wider the viewing angle the better it is. If a tablet’s screen has a narrow viewing angle, you have to hold it straight in front of your eyes to watch the content displayed on the screen, this can be very uncomfortable when you are lying down. 3. Memory micro-sd You can not have enough of it. Run a lot of apps or open too many tabs in the browser and pretty soon you will run out of memory. But you can not have unlimited amounts of it, so you have to hit for the maximum you can get. RAM Like any computer, this is the primary memory for a tablet. The more the merrier. High end tablets come with 1 GB RAM. Tablets with 2 GB RAM is also around the corner. Android tablets typically use NP DDR SDRAM or LP DDR2 SDRAM. The LP DDR2 SDRAM is better, faster and has a higher throughput and the cost difference is not much. Do not buy tablets with less than 512 MB RAM. The performance of tablets with RAM lower than 512 MB RAM is awful. It will be slow, you will often encounter “insufficient memory†messages and applications will close or hang quite frequently. NAND / eMMC ROM This is the memory that contains the actual Android operating system, drivers, system apps, settings etc. Actually the ROM (Read only memory) is a misnomer, since you can read from and write to this memory. The more space you have the better it is. Do not settle for anything less than 4GB. I have encountered tablets where they use micro SD cards as internal memory. External Storage Most tablets support external storage cards of up to 32 GB. However there are some tablets, that can only support external cards of up to 16 GB. I would suggest you to go for tablets that support the highest capacity. 4. Communications communications-antenna A tablet can have multiple mediums to communicate with other devices and networks. WiFi A tablet should support at least 802.11 b/g standards. Those are the most common WiFi standards in use and will be so for the near future. The quality of the WiFi connection and signal depends on the hardware and the firmware. Some custom ROM’s or even factory ROM’s are buggy and will drop connections or give lesser speeds. More often than not it is fixable by updating the firmware. Check the WiFi connectivity of a tablet thoroughly, before buying. Phone Not all tablets come with phone capabilities. If you do not want to use 3G USB dongles and still want to access the internet not in range of any WiFi connection, you need to have a tablet that supports SIM cards and a.GPRS (2G) b.EDGE (2G) c.HSUPA, HSDPA (3G) d.UMTS / WCDMA (3G) Almost all high end tablets support them. But you will be hard pressed to find a budget tablet that supports all of the above standards. Bluetooth This is not an essential feature but it is required if you want to transfer files among tablets, phones and other devices running different operating systems without resorting to setting up web servers to do transfers. It can also be used to control other devices that support Bluetooth enabled remotes or to connect a Bluetooth keyboard and mouse to your tablet. If a tablet has phone connectivity, it is better to have Bluetooth too. This will enable you to connect Bluetooth headphones and use them while answering or making calls. You really do not want to pick up and talk in to a 7 inch or 10 inch slate while holding it up to your ear. It not only looks ridiculous but will also tire your arms pretty quick. 5. Ports and Interfaces android-tablet-ports Try to avoid tablets with proprietary ports and stick to tablets with USB or Mini USB ports. Sadly, many high end tablets like Samsung Galaxy Tab use proprietary ports for charging, data transfer and video output. If you are buying a budget tab, I suggest you steer clear of proprietary ports. USB Ports Look for tablets that support USB 2.0 or above ports, USB OTG, Mini USB ports. That way you do not have to spend on buying port converters or docks. USB OTG / HOST enables you to connect your tablet to your computer and copy data to it just like you would on a thumb drive. USB OTG/ HOST ports are also needed when you want to connect 3G USB dongles, external wired keyboards, mouse, thumb drives and external hard disks to your tablet. Audio Socket A tablet will also have a 3.5 mm audio socket to connect head phones and mic, this is a very common feature. But you should check the build quality of the socket. Quality of sound is also an important factor, play audio files and video files to get a feel of the sound output quality. HDMI Port Some tablets come with an inbuilt mini HDMI port, you can use this to view videos, games and other content from your tablet on an external screen such as an LCD TV. This is not an essential feature, but it is nice to have it. 6. Sensors and Location android-sensor Have you seen how the content on the tablet’s LCD screen changes orientation when you rotate the device. This feat is achieved by using accelerometers. If the accelerometers also called G- Sensors are not calibrated properly you will have hard time playing games that use tilt based controls or changing orientation of the screen. Compass Some high end tablets have digital compass in them. A digital compass shows your position in reference to the four cardinal directions. This can than be used to plot a route using the inbuilt GPS. Budget tablets will not have them. Proximity It detects the presence of objects near the screen. For example , if you are talking on the phone by holding it to your ear, the screen will shut off to avoid accidental press of on screen buttons and the subsequent disruption of the on going call. It can also be used to dim or put the device and screen on standby when not in use or nobody is near it. You will not find these in budget tablets and even in many high end tablets. Barometer A barometer helps the GPS of your tablet to get a better and faster fix on your location by finding the height of your current location. If you are serious about using your tablet for navigation purpose, you should want this in your tablet. You will not find this in budget tablets and even in many high end tablets. Light The ambient light sensor in a tablet helps it to conserve battery by dimming or enhancing the brightness of the screen depending upon the surrounding light. This is not a common feature in budget tabs and not essential. GPS This helps your tablet to find your present location and use it as a navigation tool. If you want to use your tablet as a map or want to use Google Maps or any other map and navigation software, the tablet must have GPS in it. 7. Power android-power Capacity of batteries in mobile phones and tablets is measured in mAh, the more mAh you have the better it is. Do not go for tablets with less than 3000 mAh batteries. For 10 inch tablets the minimum should be 4000 mAh. Higher mAh means more battery life between charges. Apart from the mAh , the running and charging voltage is critical in getting the most battery life. A 3000 mAh battery discharging at 3.7v will last longer than a 4500 mAh battery discharging at 7.5v. Most budget tablets run at 7.5, so the batteries run out faster. In brief, go for the highest mAh and the lowest voltage. For a 7 inch go for 3500 mAh or more running at 3.7v and for 10 inch go for 4500 mAh or more running at 3.7v. 8. Casing Always go for sturdy casing, the build quality should not be cheap. The casing should feel sold. Ideally, a tablet with aluminum casing is the best. But they tend to be costlier. Handle the tablet, turn it around in your hands, press it, feel it, shake it and you will have a pretty good idea about itâ €™s build quality. Conclusion. I left out cameras, since they are not a critical factor while choosing a tablet, I may be wrong and individual preferences vary, if there are many requests to include camera types, I will put them in this guide. You can use this as guide a general guideline while you are at the electronics shop or you are reading through the specification list of tablets or phones. I hope this guide helps you to make an informed decision on buying android tablets 6 Likes |

ideology: hello pals, am using Samsung galaxy pocket, pls just yesterday, the apps that use data such as yahoo, what'sapp and others stopped working only opera, pls what could be the cause? Check ur data setting...did u change sims or may b it was network problem cos opera uses a data trime-down socket dat reduce data, so even when ur network access is limited to 1kilobyte per/second, opera wil stil go tru may just take longer. Try using other network & let me know how far 2 Likes |

Peace ro is just one of the various memoris of any tablet like you know ram, rom is the inbuilt-memory of that tablet. there are tablet with different types of rom, buh Nand-flash id the best of all and 4gb upward is better in case you dont have cash to buy extra 8gb or 16gb u can stil flex your app and games on it. |
Re: Android Phones & Tablet Q&A's by solomonsojay(m): 7:30am On May 28, 2013 |
and to the guy who mailed me about what budget-android means...low-cost android, its just same as "not ipad, galaxy or google expensive tablets" meaning you want an android but you have a specific amount you dont want to go above and you know is cant buy an ipad. so you say, "i want a budget android tablet" meaning...low-cost tabs. |
