hey,you are not alone.i have exactly same problem,and i seached all the net,but i dont find out any solution and nobody can help me. but i looking for stock ROM of lenovo a3500 to flash my tablet.i think that is only solution .but there is not any stock ROM for it available now.if you find it say me plz. support center in my country can't solve this problem and said wait for new version 4.4.2 .because in his opinion update my phone can solve my problem! but until that time i have to install my apps and games on tablet storage memory and i use sd card for music and movie files. but i am searching for stock ROM anyway...
only chane that i applied was:
1- root it with kingo
2- uninstall some default apps with clean master
what app you use for root your lenovo?
