I didn't meant to say that the apps disappear, they just stop working unexpectadilly after some days (not all of them) and I need to reinstall, but they don't disappear from the phone. About youtube I don't know what to do... Maybe reinstall the build?
Let me tell you an example: I've downloaded launcherPRO, and after only 1 day, it stopped working and it was setup to start on boot, so, it was hard to uninstall it, but thanks to easy cache cleaner app, which made a notification on boot, I was able, trought there, to unistall launcherPRO...( now I run ZEAM launcher)
Other apps that stopped working after some days were sd-booster, facebook, facebook messenger, abduction, jewels,hotmail, xda app(this one doesn't work at all), but if I reinstall they will work for maybe a week, but then, they stop working again, reinstall is needed...
