Launcher starts before SIM is unlocked

Please answer me this:
Is it normal for android devices that they display the unlock SIM card NumPad only for a short while, after which the launcher/homescreen starts normally?
I just found this out, and now I'm really unsure if it was like this from the beginning or only after i started modding...

in any case, is it possible to delay the start of the homescreen/launcher until the sim card is unlocked?

the phone is rooted by now, xposed framework installed...
it's a triple sim acer liquid e700.
the behavior seems to be the same with all launchers: the original "Acer Home", Nova Launcher, Apex Launcher...

Wi-Fi starts up too slow, Galaxy S4

Hi guys ! Haven't found this thread anywhere so I had to ask.
When I installed a new Stock ROM everything was perfect, but as time went by, my wifi started to turn on slower and slower, now it takes him about 1 minute just to turn on. When I turn it on and go to Settings it just shows a blank page until the wifi turns on.
Please, DO NOT suggest:
1. Cache wiping
2. Safe mode and uninstalling previous apps
3. Wifi boosters
4. Advanced Wifi settings, special menu settings, turning of battery savings etc

Since I have tried all of those options
And yeah, everytime I reinstall a Stock ROM it works like a charm, but I don't have time to do it every 3-4 months just to make wifi fast as a lightning, as installing a new rom takes time and reinstalling all the apps makes me very nervous
Thanks for the answers, stay cool as always ! :)
