If you have backed up your information and cleared the data from Phone, Messages, Contact Storage, and Dialer Storage, but you still have this issue, I would then recommend that you test your Evo 4G LTE in safe mode. This will disable third party apps and processes from launching when the phone is powered on. You will still be able to make and receive calls, text messages, email, and use the internet.
To put your Evo 4G LTE into Safe Mode, use the following steps. Be patient with these steps, you may not get it into Safe Mode on the first attempt.
Go into settings>power and uncheck Fastboot, then power off your phone.
With the phone powered off, press the Power key on your device.
When you see the first load screen, press & hold Volume Down key until OS loads.
"Safe Mode" text will appear on the lower left of screen to advise that you are in safe mode,to get out of safe mode just restart the phone.
If you can access these apps fine in safe mode, this would indicate some kind of conflict or interference from a third party application. You would need to rule them out by uninstalling the apps until you find that the phone is working normally again.
If the issue persists in safe mode, I would then recommend that you back up your data and perform a factory reset. If you would like assistance with backing up your data, please let me know and I will walk you through this process. The reset will restore the phone to a "like new" state. All personal data such as emails, text messages, internet bookmarks, photos, videos, music, documents, settings, call history, market apps, and any contacts and calendar entries that have not been backed up to a PC or server will be erased. Data on the SD card is not affected by the reset.
To reset your Evo 4G LTE, use the following method :
***If you use Google Wallet, please perform these steps before you perform the reset***
-Open Google Wallet application
-Tap on Menu
-Tap on Settings
-Tap on Reset Google Wallet
1. With the device turned off, press and hold the Volume Down button. While continuing to hold this, press and release the Power Button.
2. When the factory reset menu appears, then release the Volume Down button.
3. Use the Volume Down button again to highlight FACTORY RESET, and then press the Power Button to select it.
I hope that these steps help you to gain access to these apps properly again, Stephen, and I hope you have a great day!
