About Gift Card Redemption Problems

If you're having problems redeeming a gift card to your account, it's possible that the gift card claim code has already been redeemed to your account. After you've entered the claim code on our site, we'll keep the balance in your account for use on future purchases so that you don't need to enter the claim code again. If you're seeing an error message that the gift card has already been redeemed, it's likely because the gift card claim code has already been applied to your account. To check whether the funds are already on your account, view your gift card balance in Your AccountYour Account. If you're still having problems, check the Gift Card Terms & Conditions to make sure your order meets the rules and restrictions for paying with a gift card. If your Amazon.com Gift Card claim code is scratched off or can't be clearly read, you can contact us with the 16 or 30 digit number on the back of the card.If the gift card is for a retailer other than Amazon.com, please contact that retailer for assistance.

There is no charge.
You already have joined. And you did so without giving any credit card or other financial information. Anytime you can wander around a site without giving that info, it's a pretty good indication that it's free.

I'm not so sure if I can give you a solution to this if you haven't already fixed it, but I'll try. If you purchased your tablet from somewhere else used by another individual you may have no way to get passed the pass word except to call the dealer of the tablet and tell them you need help with it. They usually have a phone number for these companies. You will need the model, serial number and all identification of your tablet and they can help you. Usually you just reset the tablet back to factory to delete all off.

Forcing a complete Reset works. This option keeps all your existing data.

1. Hold Volume Down and Power button until presented with two icons (Open box and an arrow and an Adroid Doll)
2. Select the left option.
3. Volume down to toggle between options. Volume up to select.
4. Will be presented with the Recovery Console.
5. Select the first option "Reset"
6. Here the volume buttons are used to navigate up and down and the power button to select.

After selecting the reset option your Galaxy tab will fully boot up again..

on idevice like the iphone and iPad?
well it depend on what IOS version you are on. If you are using anything before IOS 7 the way to attach photos is kinda backwards.

you don't actually attach photos but you choose the photos you want to send in an email.

anything below IOS 7
1)Tap on the PHOTO app and Go into you photos.
2)Choose the photos. You can send one or more. If you are in your photos you should have an icon on the top right (its the last icon, a picture of an arrow going out of a square). Once you hit that icon you are able to mark your photos to send . Each photos you choose will have a check mark on it.
3)Once you have all the photos marked hit the "SHARE" icon on the top left of the screen. From there you can email or message those marked photos. Once you tap on the email, your email app will open up with each one of the photos attached to the body.

IOS 7 method
If you are looking at an individual photo from your PHOTO app, you can tap on the share icon (the square with an arrow pointing up) at the bottom left to bring your email and text share options
Sometimes when you go into your photos app it will bring up in yearly view... in that case
1)Tap on the PHOTO app and Go into you photos.
2)Choose your photos. If your app opens in "YEARS" view tap on the photos to zoom into "COLLECTIONS" view. From there tap on the collection where the photo you want to send is located. That would bring you to "MOMENTS" view. With IOS 7 the photos apps arrange your photos by YEARS>>COLLECTION>>MOMENTS. In MOMENTS view you can tap on the "SELECT" on the top right which will allow you to choose the photos you want to send in an email.

3)After you choose a photo(s) the icon on the bottom left (one with an arrow pointing up from a square - this is called the share icon) is available to tap. If you hit that you'll get all the option as to how to share those photos including facebook and twitter

Try this and see if this helps. Go into your network settings and press the little blue button to the right to see the network options you should see it already has a dns server and ip adress. Where it says auto join turn this off. Now see if you are able to connect. hope this helps kidromulous

You could be able to enable presentation mode by pressing the "settings" button on the bootom of your display, next to the power button and the "ctrl" and the rotate button. After you press that, your dell control point manager should pop up and then go to the tablet tab on the left and open it. after that, go to the display tab and you should see an option that allows you to turn your presentation mode on.
