Lag in the game and problems

I have problems with android minecraft the performance of the game has been bad since the last update, for example, the game menu in the creative and survival is bad and goes with a lot of delay which usually ran between 40 and 45 fps and now with less Of 25 Fps and sometimes until the game closes then the portal of the end does not see the image that has to produce then the loading times between the menus are not the best and so they do not tell me anything I have minecraft bought maybe not With this account but if with another and on youtube are pirating the license of minecraft with a program if they are interested is called luky patcher thanks for your understanding
