I have just updated my iPad. I wish I had not. Why when I go to my emails I only see a few of them at once and the right side of the screen is black?

Hi,
I'm guessing that there could be a glitch in the processor's circuits.

the following will not erase or remove anything on your iPad, but do a software reset of the memory circuits :
Hold down both these buttons at the same time :
- "Home" and the "On/Off" button (right-hand corner)
- keep holding them both down firmly, disregarding any message, until the Apple logo appears.

i do this simple procedure about once per month, just to keep things working more smoothly.
The top corner button is really just a "screen off" button. An iPad is a small computer, and needs to be turned completely off once in a while.
let me know if this doesn't work, as there may be another solution related to your iPad being logged-in and connected to iCloud.

see if this helps you out..
To resolve this you need to alter the port that your iPhone or iPad uses to send mailwhich can be done as follows. Go to Mail, Contacts, Calendars and select the account you wish to change. On the next screen, scroll down to the "Outgoing Mail Server" section and select the SMTP server that is listed.

the email is your username that is attached to the password if you have updated your accounts to a new email your icloud access should work if you didnt then notify provider for assistance

To get updates on your IPad, you need to be connected to your internet. Touch your "Settings" button on your screen. Scroll down to "General" and touch to open. On the right hand side, you'll see "Software Update". Touch that to open it. You should see the update available. At the bottom, it should say "Download and Install. Touch it to open and it should start installing. (After you enter your passcode, if you have one.)

If you keep your backup with your blobs it's time to restore back then.

How to delete or move ALL emails at once in non-jail broken ipad or iphone
It took me weeks of research to figure out finally how to decode this yet another secretive secret of apple. There is a perfect way of deleting ALL emails at once without jailbreaking your iphone or ipad...and here it is:
>> Open Inbox >> Edit >> Mark All >> Mark As Read [Added May 21, 2014 by Adrian; this extra step makes the difference between success & failure for some.]
>> Open Inbox >> Edit >> Check/select the top message; it will highlight the move button.
>> Press and hold the move button and uncheck the message that you had checked earlier.
>> Lift all your fingers off from the ipad screen and leave it alone. Wait until all your messages pile up on the right hand portion of the screen (in ipad); iphone will give you the actual number of emails it has selected for the action. Now they are just waiting for your command to be moved ALL at once.
>> Choose trash to delete all of them or any other folder where u want to move them, like one piece. Remember this will replicate your action on the server so you will ACTUALLY move them or delete them on the server and not just the ipad.
Once you have moved all messages to the trash you can either leave them there for the scheduled cleaning or empty it right away by doing this: go to trash folder and touch Edit. The Delete All button shows up at the bottom of the screen. Hit it! You're done!
If you do not see the effects of your actions on the server make sure you have enabled your email accounts for such actions.
Tips:
1. Please give enough time (could take up to several minutes depending the number of emails to be moved) for the emails to be selected for the move. Your screen will become unresponsive while all emails are being packaged. Once emails are ready, in ipad, you will see them zoomed out on the right hand side of the screen, and in iphone you will see the message showing you the actual number of messages that have been selected.
2. Avoid purging very large number of emails, the mail app might freeze or crash. If your inbox has thousands of emails change your sync settings in mail settings to fill lesser number of emails in your inbox.
3. [Added Jul 20, 2014 by Adrian] Many people have reported needing to repeat the above procedure several times before it succeeds. (I too have found this to be necessary a few times on my iPhone but not on my iPad-go figure.) So my final tip is to repeat the procedure 3-4 times if the mail doesn't disappear the first time. In my experience, if your messages disappear momentarily and then reappear, repeating the procedure will eventually make them stay deleted for good.
4. [Added Sep 18, 2014 by Adrian] If you are using IOS 8, there is a setting that may reduce emails piling up on your device! Go to Settings -> Messages and select Keep Messages under the Message History header. You'll be able to choose to keep your messages for 30 Days, 1 Year, or Forever.

The following works on devices with iOS7
1. go to the homescreen by pressing the home button
2. launch the "Settings" app
3. search on the left side for "Mail, Contacts, Calendars" and tap on
4. on the right side you will see "Accounts"
5. tap on the account name you would like to remove
6. the account details will appear (ie. your email address)
7. on the bottom you will have a "Delete Account" button.
8. By taping the button you can delete the account.

Be ware an account can be associated with multiple apps not only email. By deleting the account you will not receive associated calendars, notes, or contacts.

If you would like to remove only the emails associated with one account you should switch off the email option for that account on the same screen that appears at step 6.

1. If you have no sound at all, even in the Music App, try rebooting the iPad.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
2. If you lost sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the control center. Swipe up from the bottom of the screen to get to control center . Tap on the bell icon and system sounds will return.
If you have the side switch set to mute system sounds, then the screen lock can be accessed in the same manner as described above.
This support article from Apple explains how the side switch works.

3. Try cleaning the dock connector opening of the iPad with a soft brush and just a little bit of rubbing alcohol.
4. Reset all settings. Settings>General>Reset>Reset All Settings.

Try a factory reset.
