Sony Xperia Z3 and KingRoot Issues

[tewksbg]

I have a T-Mobile Sony Xperia Z3 (D6616) running Android version 5.0.2 and has Sony stock build of 23.1.C.0.399. I have also installed KingRoot V4.9.2 143 from an app found on the Internet. I was nervous when I installed it, since the website looked official, but was in Chinese. When I installed the apk on my device, it restarted several time (the app said it would do that) and after it was successfully able to install root permissions, I went to Terminal Emulator (downloaded from Google Play), and ran the following command:

su

And I was asked by KingRoot to allow root permissions. I have since been able to run root applications with no issue.

Now with my question/concern. I have been having issues with applications automatically shutting down right after leaving their screens. An example is when I was running Spotify (downloaded from Google Play), and after a few seconds on my Home screen, Spotify was closed. I never had issues before with Spotify, not until I installed KingRoot. Is there something I am missing or something else?

After typing this up, I also want to note that no mods were/are installed. I tried posting screenshots, but I am still subject to the 10 post rule .

I figure out how to upload images to a XDA album:

The best thing to do when you root your phone with kingroot is to install a recovery and flash a prerooted stock rom to clear all the China sh..t.

Locked Bootloader...

I would, but I was under the impression that my phone had a locked bootloader and I could not flash a custom recovery, and as result, I can not flash a prerooted stock rom.

If you have root access you can flash recovery on locked bootloader.
