With the so-called Wipe cache partition on your Samsung Galaxy Tab 4 you can delete old system files, which are temporary in nature, on the tablet. This old system temporary files cause problems in Android Lollipop 5.1. In most cases the following method helps to eliminate the errors in Android Lollipop on the Samsung Galaxy Tab 4:
Switch as first thing your Samsung Galaxy Tab 4 completely off by long pressing the Power On / Off button. Wait until the tablet is turned off. Now you have to press and hold the following key combination to turn the tablet on again:
- Power On / Off
- Volume +
- Home button
When the Samsung Galaxy Tab 4 vibrates once, the release the power on/ off button but keep the other two keys from the key combination pressed until a small menu, similar to DOS, appears on the display.
Now mark the entry "Wipe Cache partition" with the volume down key. With the Power On / Off button the entry will be selected and the process is started. This usually takes only a few seconds.
Then the previously displayed menu reappears. Now select the first entry with "Reboot system now" and execute the command again with a pressing the power button. Your Samsung Galaxy Tab 4 will now reboot.
Your device should now all work as you would expect from your tablet. If this is not the case, we recommend you despite the expense to perform a "factory reset" on the Samsung Galaxy Tab. 4 This is usually required after an update with Version Jump (Android 4.4.2 to Android Lollipop 5.1) and also makes sense.
