I have to complain a mobile company, so, I have written a complain.
Please make correction if any.

"While charging my phone, pressing one icon or application open multiple application at once, usually when my battery charged between 90-100%.
For Example, When I press Youtube icon to open it, other application along with youtube get open automatically.
This problem also takes place while typing, when I type one letter, automatically many letters are typed own by own."
