I ACCIDENTALLY SET WRONG PERMISSIONS FOR /system/app/ directory and now I get ERRORS

Basically, I was installing an app as a system app with ADB. When I suddenly accidentally.
DID: adb shell chmod 644 /system/app/
And now I get the error: Unfortunately the process Com.Android.Phone has stopped.
And it says no SIM CARD! I broke the permissions and I wanna fix this.
The Message pops up every second!

What are the original permissions for /system/app/ so I can set it back and be relieved!?

Can't add contacts found in Exchange Directory

I'm searching my contacts for a specific contact. I find that he's not in my phone, rather I found him in my company's Exchange directory.

I'm clicking everywhere, but I can't anywhere in the Xperia Contacts UI the button of function to add that specific contact to my local directory.

Any idea how to do this? Every other Android phone I've ever owned has this option.

Samsung S6 Edge lost track of media / pictures / directory structure changed

Just a quick one folks, a couple of weeks ago I was alarmed to see my pictures had suddenly dissapeared from the gallery, and no amount of messing seemed to get them back. I downloaded a file explorer and found them once again in >root>sdcard>DCIM>camera. New pictures seem to be stored in >root>sdcard>Pictures.
Anyway so at least they are not lost.

However this change has also affected music. I can only navigate to music files with VLC, all other media players I have tried do not show anything at all. When I select a track as usual VLC will play that track then stop playing! I have tried moving the directory without luck.

I would rather not reset the phone, so if anyone has any ideas as to what can be the matter let me know.

Phone is standard EE

Internal storage has space but not /system directory. Help needed!!!!!!!!!!!!!!

Hello everyone. I am facing a serious problem. I have 500+mb in my internal storage but the /system directory has oly 5 mb left. I need the /system directory to be about 100mb free because i need to convert some user apps into system apps. Moreover i know that i can uninstall some bloatware to increase space but trust me i removed all the unnecessary apps. Since /system directory is a part of the internal storage is there any method to allocate more space to /system.? Screenshots included.
