Try this, but this wll also wipe all data from your phone. so back up your stuff first

Step 1 Power down the Kyocera Hydro smartphone. If the phone is frozen, pull out the battery, wait a few seconds and reinstall it to ensure the phone is off.
Step 2
Press and hold the "Volume Down" button and then hold down the "Power" button.
Step 3
Release the buttons after a few seconds when you see the Android System Recovery screen.
Step 4
Press the "Volume Down" button to highlight "Wipe Data/Factory Reset" and then press the "Power" button to select it.
Step 5

Take out battery from laptop and disconnect power cable. Keep the power button pressed for 30 seconds and then plug the power cable. This will remove static charge from laptop and should resolve the display issue,

Try to reset it by taking out the batteries and leaving to sit for a minute or so, if that doesn't work take out the small battery as well and leave it sit, if you're still stuck you can call ti-cares (800-842-2737) they're generally very helpful.

There are three possible solutions here. From what you are describing to me, you say the screen displays a couple of random numbers and letters, including a solid vertical line in the upper right corner, are scattered across the screen? Sounds like you are still in graphing mode. There is nothing wrong with your batteries and changing them won't help because I already know that you didn't change the CR Lithium Battery. This is the "memory card" for the TI-83 Plus. If you don't change that, when you insert new AAA batteries in the calculator, the memory has not been deleted. You probably don't remember, but the calculator remembers the last problem that you did, which was a graphing calculation. Try pressing the "Graph" button and the calculator will go back to function mode. If this doesn't work, try resetting all the memory.

1. Remove a battery from the battery bay.
2. Press and hold the CLEAR button while re-installing the battery.
3. While still pressing the CLEAR key, press and hold down the ON button. If the home screen displays, release the keys.
4. If the home screen is displayed, press 2nd MEMto display the memory menu.
5. Select 7:Reset to display the "RAM ARCHIVE ALL" menu.
6. Press the right arrow twice to display the "ALL" menu.
7. Select 1:All Memory to display the "RESET MEMORY" menu.
8. To proceed with the reset, select 2:Reset. The message "MEM cleared" is displayed on the home screen.

If this doesn't work, try changing the CR Lithium Battery. It is located in the battery bay at the top with the cross-head screw in it (It says BACK-UP BATTERY). It tells you what type of battery it takes and how to insert them in. I hope these possible solutions help. If all of them don't, then the only other thing I can think of is that it has some internal part alignment issues or a cold soldering iron blob, on the inside of the calculator. I saw one time on the Internet that cold soldering irons can sometimes make electronics not work properly.

Try to hold down the off button and restart it, if it still shows the same screen take it for servicing.

My radio was stuck on "scanning media" and the regular reset (volume up and Mode) did not work.
Nothing that I did, fixed it...
I called Delphi and they said...
(1) Put radio in it's cradle, press Volume UP/Mode buttons for 3 seconds until it resets.
(2)Then when the "scanning media" message appears press up arrow, down arrow, up arrow.

My delphi screen unlocked. I LOST everything that I had recorded, but that was fine with me.

I had to update the firmware and everything is working fine.

Losing all my recorded songs was much better than having to send in my radio!

Hopefully this will work for you!
Delphi was extremely helpful and very nice so don't be afraid to call them if this doesn't work!

same problem

if anyone has any suggestions, it would be appreciated.

Warning the following tip will erase apps and programs from calculator!
The following will run the self-test mode
Press mode then press alpha then press s then press enter
If you want to get out of the self test press the on button in case you want to attempt to save/transfer apps, programs, variables etc.
The calculator will start to test itself it'll countdown and display numbers on the screen. It can get better sometimes other times a replacement of both the cr1616/cr1620 lithium battery and the 4 AAAA batteries work. Also ensure that you've attempted to clear out all the memory and reset the calculator. To delete all variables, tables, graphs, etc: Press 2nd button then press MEM then press 2 then press 1.
To reset the calculator press 2nd button then press MEM then press 7 then press the left arrow then press 1 then press 2.
