[Honor 6C][DIG-L21HN] Several broken system apps - Honor 6, 6 Plus Q&A, Help & Troubleshooting

About half a year ago, some of the system apps started to malfunction. Most noticeable is gallery - it closes immediately after trying to load thumbnails.
Photo viewer, which comes with gallery, also crashes a second after loading, without even showing a picture.
Google Play Market crashes randomly, with usually a minute after loading, or just nearly instantly.
Sometimes after rebooting, if Bluetooth was disabled, it just won't turn on again, until i reboot it several times.
There's also random weird "fast" reboots, when my phone crashes(???) and automatically reboots, and... does it much faster than usual, manual reboot.
This is a very weird case and i was unable to find any information about this, but something tells me it might be some kind of memory corruption? I've tried to do standard procedures of erasing app's cache data, downgrading them and so on, and nothing helped.
Phone is rooted with Magisk and has TWRP.

apps stuck on "posting" until cycling airplane/data on&off

So sometimes on wi-fi I have to cycle airplane mode on and off to get some apps to finally post(facebook, snapchat, google play store, etc). Otherwise it is just stuck posting or it finally times out and then I can use the "try again" option and then it posts it.
Have searched around, but I don't see this as a common problem. I'm running stock cm12. I have cleared cache, installed/uninstalled apps, etc. Still same annoyance from time to time. Any remedy?

Moto G - Won't turn on after Cache partition reset / factory reset (?)

To start off, recently out of the blue, whenever I would open any app and had other apps already open, the current app I would be on would close. For example, after trying to open the Google Play Music app and having it close seven times after opening it, it'll finally let me open the app and then listen to music. I click the change song button and then the app crashes with a notification saying this or just crashes without one. I read also this had to do with the Google Play Services app. I disabled it and enabled it twice. No difference at all.
This is for all applications and drove me insane. I eventually decided to research it and came up with the answer of resetting the cache partition. I did so but then was stuck in boot loop. I wasn't really sure what to do at this point. Perhaps this was a mistake but, I decided to factory reset my phone. Now, the boot loop only vibrates and goes to the light-green Motorola symbol. Nothing else for hours.
The previous times I've had to reset this phone (about four now) the device would show the commands it's doing and then you would see it finish. It didn't do it this time, simply saying resetting cache and reformatting.
I'm lost at this point.
Perhaps someone will have knowledge about this?
Try to reinstall rom from fastboot.

Problems with MM rebooting (even after 2 resets)

Hello,
I have a new AT&T H900 not rooted for past 5 months. It was working fine until the MM forced update. It started to shut down (apps stopped responding) some of my apps. I read that I needed to reboot fresh, so I did. Even directly after reboot, apps still kept shutting down (stock apps like Google, messaging, just to name a few) at different times, even before adding my old apps. I decided to reboot a 2nd time with the addition of clearing the cache every time ( I read somewhere that this should help). It seems that the apps seem stable, but now my device keeps rebooting at a moments notice (specifically when it is computing multi tasks). It has become very unstable. How can I fix this? Should I try a 3rd reboot? Thanks.

This is very odd. Usally apps closing like that mems theirs a compatibility issue. For now lets focus on your rebooting.
Try leaving your phone with the battery pulles for atleast 10 minutes. If that doeant solve your problem, see if it randomly reboots when you have it charging. My G3 did that if i ran more than one thig with it off the charger. And my case was a bad battery. So it may be your problem aswell

Sudden serious performance issues and errors

Yesterday I installed DU Cleaner I clicked the button it did the usual clear cache stopped running apps etc, but I noticed at the end it stopped some startup services and apps.
I have just rebooted my phone, it took about 10 mins to boot up not he usual 1 or 2 , then I was getting a lot of app errors unfortunately*** has stopped working etc, and now it is supper sluggish even wringing this post out, every few words it freezes and takes time to catch up.
There is nothing on the app to adjust startup items, I me ruined on a magisk thread that I have a problem with startup managers they just don't seem to work for me so I have no idea how to resolve my problem.
Edit: I tried whiping cache and delvik but one weird thing when I usually do that it has to optimise over 300 apps as usually it's slow but normal but now it only does about 150 and it's done withing a few seconds. One of the apps that's constantly crashing is WiFi direct share, the error message keeps popping up

Clearing Dalvik cache via TWRP causes apps to launch A LOT slower

Hello guys! I have a bit tricky/technical question here. Yesterday I wanted to refresh my Pixel 3 a bit (clean flash with the December firmware, then rooted and never received OTA updates) so I booted TWRP and cleared the Dalvik Cache. When I rebooted, I noticed that some apps (especially Google ones like Youtube, built-in Camera, Maps) all suffer from a slow launch. A lot slower. Like... 3-4 seconds before the YouTube app can show anything different than the white splash screen with the red play logo. The Camera is also slow enough to see the fully black screen with the small centered camera icon for 2 seconds too. This only happens on clean start (when the app is cleared from the Recent Apps panel).
I checked the /data/dalvik-cache folder and it seems that all files are re-created after the wipe, however it's fairly obvious that the apps are no longer running from the odex/oat/whatever it's called now binaries. Clearing the app cache doesn't solve the issue, I've tried that. The only 'working' solution seems to be uninstalling the offending apps (e.g. Youtube) and then performing a clean install from the PlayStore. Then, the app launches fast as usual. However, I'm afraid that I can't do this for all of my apps (I'm going to lose preferences) plus I'm kind of afraid that the System apps (like the "Settings" app) cannot be re-installed with such ease and I will be stick with slow 'clean starts' here and there forever.
Do you guys know how I can trigger the 'App optimization' process that is observed when an OTA update is applied? You know, that time consuming screen that says 'Optimizing apps, 7 of 82'. This is when Android rebuilds the dalvik-cache and apparently I need to manually perform that. The other option would be to perform a clean flash (I'm already 4 months behind anyway), but I'm not particularly thrilled by the idea. Any suggestions on how to manually trigger the App Optimization process in order to rebuild my Dalvik?
I don't have a fix for you, but don't do that with TWRP. It does not apply to newer phones.
