Need help disabling MLT through accessing LG Hidden menu through dialpad (AT&T H950)

Hi, I need some help reaching the LG hidden menu on my stock 5.1.1 AT&T G Flex2 (H950) in order to disable the battery-draining MLT service. I've read through all of the related threads to this issue, trying the combinations below.

277634#*#
3845#*950#

Some of the threads have recommended using a shortcut creation app such as QuickShortcutMaker, Secure Settings, and Shortcut Master, which I have all tried but all seem to require rooting to access the hidden menu. I would have no problem paying the for the Shortcut Master pro, but I have no guarantee that it will allow me to launch the hidden menu shortcut. I doubt that it will, as other apps that allowed me to create homescreen shortcuts have failed to open it.

I have triedLauncherPro to create a hidden menu shortcut to the homescreen, but still have not had success in opening it.

Has anyone found an alternate code for the dialpad to access the hidden menu without root or custom PR rom? This is on AT&T 5.1.1 that I received OTA through gophone. If anyone could help me out regarding this issue, I would greatly appreciate it.

Accessing Notifications Centre on the Lockscreen

Hi, I'm a new to Huawei's EMUI and I'm having trouble accessing my notifications centre on my lockscreen. I've played around with the settings and still no luck. Is it not possible to access the notifications centre when I have a PIN lockscreen ? Appreciate all the help I can get.

Brutal lag when accessing contacts

Apologies if this has been posted elsewhere, I had a quick scan of the threads and couldn’t see it.

Anyone else having issues accessing Contacts on G4 ? I presently have circa 300 contacts, all sync’d from Outlook, so they are quite detail heavy, some pics, many notes etc….

Whenever I go to access the Contacts it can take 10-12 seconds for the list to appear. I wondered if it was to do with the volume of contacts, so I removed 300 (as had 600 before), but it didn’t make any difference at all.

The ‘online search’ function is unchecked. The rest of the phones functions are working lightning fast, just the Contacts.

LG’s only suggestion is to “factory reset the device and try again” – brilliant.

I've already deleted all contacts and re-sync. Pretty much all apps have their contact sync turn off. Nothing I do seems to make any difference.

Any help / suggestions much appreciated. I’m at the point where I’m going to ditch it and go back to Samsung (I should never have strayed, grass is always greener etc…).
