To improve android platform

Give us feature to lock the installation and uninstallation process with security code in android …
Why am asking this feature is unauthorized persons have chance to install some apps in mobile and get the personnel content in mobile….
And also give us unique code separately for every android mobile to avoid flashing the mobile after theft that is by using that unique code only peoples are able to flash. Give that unique code in every mobile box package…. This gives more security for android users and easily catch the thief by tracking software… it is better when it asks that unique code to access bootloader…..
One more thing in android is there is no proper security for apps like filemanager, whatsapp, etc.
Why because if we put some security code for apps like these apps it’s easy to access even if the app protected using some app by force close that security app which is running…
So give us feature to lock the apps in android by inbuilt. If the android security to protect app inbuilt then there is no chance to access that app without security. If the someone tries to open the app by force close that particular security app which is inbuilt then automatically the mobile will restart and the app start run again and doesn’t allow unauthorized persons to access the files in mobile and also give us feature to lock the file that is doesn’t show the contents in mobile even if we access through datacable or card reader, etc separately….

By force close some unwanted downloaded apps we save more battery life in android. So show those apps and give us feature to force close those desired app in single click with task manager.

Give us feedback feature in android os inbuilt…
