Hi there. The app would be an ultimate alternative if it wasn't for:
1) It drains my battery really bad. I've tried all sort of tricks to fix the issue, with no success at all. And yes, I have just a small widget I've made, with a blank wallpaper.
2) My phone lags a lot during the first 15 or 20 seconds after unlocking.
3) It sometimes crashes.
A pity, cause I really like having the freedom to create a custom lock screen. Other apps just give you a bunch of choices you can't edit or, like Locker Master, pretend you are free to create your own, when in fact you are not, cause the only thing you can chosse "outside" the program is the wallpaper.
