How to fix a force close loop on Android with phone access?
Issue solved

Boot in recovery mode &gt; Choose &quot;Wipe cache partition&quot; and reboot.

No need to Factory reset and lose all data.
Long description
I also suddenly had my Samsung Galaxy SII (SGS2 GT-i9100) running Android 2.3.4 with a rush of continuous force close pop up windows, a lot of apps that seemed to try to connect to internet would trigger a popup force close window, many apps crashed. I hardly managed to quickly close the popups and turn off the phone, removed the battery and turned it on again but the problem persisted and got worse so in the end I got this popup again and again:
&quot;The application LogsProvider (process com.sec.android.provider.logsprovider) has stopped unexpectedly. Please try again. Force Close.&quot;
And really had to try hard to close all those popups quickly to switch off the phone.
I found the solution here
Which is:

Turn off the phone (hold the power button if the power-off menu won't appear).
Boot in recovery mode (holding volume up key + home key + power button at same time).
Choose the fourth option &quot;wipe cache partition&quot; (using the volume keys to select option and then Home button to excecute).
Allow to reboot normally and problem solved.
