I'm an owner of an lg l9 ii.
One day, after i bought the phone i made an update to 4.4.2
But now the dialer lags when i loaded it for first time. As it is in memory opens instantly, but when i clean ram i see a small lag only the first time i open it.
So to solve the problem, i want the dialer to be loaded permanently in memory.
Is that possible without root, because as far i search the forum isn't that possible with 442 rom.
