How do I reset a samsung?

If your Samsung fridge is showing a plug-in sign on the display, it usually indicates that the refrigerator is not detecting a power source. However, if the cooling is normal, it is likely a display error.
To clear the display error and restore normal settings on your Samsung fridge, you can try the following steps:

1. Unplug the fridge from the power source and wait for at least 30 seconds.
2. Plug the fridge back into the power source and check if the error message has disappeared.
3. If the error message is still there, try resetting the fridge by pressing and holding the power freeze and power cool buttons simultaneously for about 10 seconds. This should reset the display and restore normal settings.

If the error message persists despite trying the above steps, it might be an indication of a more serious problem with the fridge. In such cases, it's best to contact Samsung customer support or a certified technician to diagnose and fix the issue.

I had this android tablet http://touch-tablet.co.uk/product/7-android-42-a20-tablet/

And to reset it you had to the following: You hold the power button and -vol button together for about 5 seconds.
Then you let go of the power button and keep the -vol button still held until the android creature loads and gives you some options.
Choose factory/data reset using volume keys.

Good luck

So sorry to hear/read about this challenge you are having.
You've provided a few details to help you out; so also is it that you've probably left a few otter details out too.
First, the android logo which appears... is it lying on its back with its tummy open and a 'no command' writing also displayed?

Or is it simply the android logo ONLY.

In any case, once you do the hard reset and the android logo re-appears, try and pushing either the volume up or volume down button.

Next, check and see if it now displays the various command options on the screen.

Otherwise, when the android logo reappears, you can try press one of the following 'home button' or 'back button' or 'opened tabs button' and see if the reset menu/command options become displayed.

No, there isn't.

If you want, you can try doing a hard reset, which will erase everything that's not on external storages. Here is the hard reset procedure:

1. Removing the battery without turning it off.
2. Reinstall the battery and turn the phone on with navigator key pressed down.
3. press any key to skip to prompt.
4. press yes to reset the phone.

Good luck.
