Hi @mahmoudi1968,
Try the following and check if either resolves the problem:
[https://www.t-mobile.com/support/devices/android/samsung-galaxy-note-101-2014-edition/wipe-cache-partition-samsung-galaxy-note-101|Wipe the cache partition] and check if it now works OK
If still no good, try starting the tablet in [https://www.verizon.com/support/knowledge-base-185057/|safe mode] and see if it works OK.
If it does then a ''downloaded'' app is the cause of the problem. The trick is to find out which one. You will need to uninstall each ''downloaded'' app one by one and test the tablet in normal mode between each uninstall to see it it works OK. When it does then the last ''downloaded'' app that was uninstalled was the culprit. A ''download'' app is one that you downloaded and installed and didn’t come pre-installed with the tablet
