Make sure to back up anything that you want to save before proceeding with the factory reset.  Open the Settings app and tap "Backup & reset" to see your backup options. You can back up most data to your Google account, including contacts and other settings. Photos will need to be backed up to your computer or to your Google Photos account. See Transfer Photos from Android to Computer for instructions. You can reset your Android device from the Settings app. Note that the following instructions may vary slightly depending on your Android model and manufacturer, but the process is generally the same. If you can't access the Settings app because you are locked out of the device, see the last step of this section.  Select "Backup & reset." You can usually find this in the "Personal" section. Tap "Factory data reset" and confirm. This will begin erasing all of the data on the Android and will allow you to setup the device as if it just came out of the box. If you can't access your Android device because you're locked out, or it's been lost and you want to wipe it remotely, you can use the Android Device Manager.  Visit google.com/android/devicemanager or open the Android Device Manager app on another Android device and log in with your Google account. Click the "Erase" button in your Android device's card. Confirm that you want to erase the device. If you can't access your Android device and can't use Android Device Manager, you can reset your Android using Recovery Mode.  Turn your Android phone completely off. Press and hold the Recovery Mode buttons. These vary depending on your device, but the most common combinations are Volume Up + Home + Power or Volume Down + Power. Continue holding these buttons until the Recovery Mode logo appears. Use the volume buttons to navigate the recovery menu and the Power button to make selections. Select "recovery" and then "wipe data/factory reset." Newer Android devices have an Activation Lock that ties the phone to the owner's Google account. This prevents a thief from activating a stolen Android phone. If you are prompted, you will need to enter the password for the Google account that was associated with the device before the reset in order to setup the device. If you purchased the Android used, you'll need to contact the original owner and have them enter the password for you.
Summary: Back up any data you want to save. Reset your Android from the Settings app. Reset your Android from the Android Device Manager. Reset your Android using Recovery Mode. Enter the Google Account password for the original owner (if prompted).

You’ll need to know exactly what coin you're looking at to determine its specific value. Modern coins will include a date of issue printed on the front or back of the coin itself. They will probably also name the country of origin.  If the information printed on the coin is printed in a language you can’t read, consult a world coin reference book or website. These will include images that will help you match your coin. These guides can also be used to help you determine how old coins without a printed date are. If you cannot find the coin in a book due to lack of identifiers, try to determine general area (i.e. Sinosphere, Islamic Countries, Core African). Broadening your search first may help you narrow in on the correct country. The value of a coin is greatly affected by its condition. Higher quality coins are generally more valuable than ones that are blemished or dirty.  Coins that were never used are known as uncirculated. Coins are rated from “mint” (perfect) condition, all the way down to “poor” (dirty or damaged). If you have a coin that you think might be rare or valuable, don’t attempt to clean it yourself. Take it to an expert to have it cleaned without damaging it and lowering its value. If a coin is severely damaged, it might just be worth the value of the metal itself. Some websites will make values for some coins freely available. Check with an professional organization like the Professional Numismatics Guild. Look up your coin according to its date and origin, and you may be able to find its current  value. A number of factors (including condition and current demand) impact the amount a coin can actually be sold for, so use the value you find online only as a ballpark figure. If you can’t find the value of your coin online, consult a reference such as the Standard Catalog of World Coins, or the Guide Book of United States Coins. These references are especially useful because they may list several values for a particular coin:  The “book” value (a generally accepted value of the coin) The “buy” value (what a dealer would pay to buy the coin from you) The retail value (what a dealer would sell a coin to a customer for) The wholesale value (what a dealer might sell the coin to another dealer for, especially when several coins are sold together) The value of coins can go up and down, since they are driven by interests that can change. When lots of people want to buy a certain type of coin, the value may go up. Rare or unusually fine coins are often more valuable than common ones. Finally, commemorative (special issue) coins may also be especially valuable. Take these values into account when calculating the value of your coin. For instance, you may have a type of coin that is not especially rare. However, if it is in mint condition, and most coins of that type are not, its value may be higher than the normal “book” value.

Problem: Article: You want to ensure your hands are completely clean before you sit down for your meal. In Indian culture, the left hand is commonly viewed as dirty and unsanitary, and therefore rude to eat with. Avoid serving, eating, or touching any of the food with your left hand. Avoid letting the food touch your palms. Hold the food near the tips of your fingers when you're bringing it to your mouth. It's custom to sample each dish individually. This goes for any main dishes and side dishes but does not include the bread, rice, or daal. For example, you wouldn't mix a vegetable dish with a meat dish in the same bite, or eat one of the side dishes with one of the main dishes in the same bite.
Summary:
Wash your hands before you eat. Eat with your right hand only. Use only your fingers to pick up food. Take bites of one dish at a time.
