Mobile data problem?! - Samsung Galaxy J7 Questions & Answers

Hello !
Did anyone else experience mobile data bug after the latest update? My data won't turn on unless I put my phone in and out of airplane mode first. I tried doing network reset and wiped the cache in recovery mode but nothing helped. I don't want to to do the hard reset because I'm hoping for the oreo update and I'm planning to do the reset then. Is there any other way to solve this problem?

Bluetooth Problem

Bluetooth won't start. It keeps turning off when I tried to turn on. Im using Android 4.0.4. Can you guys help me please?
Do you have AIRPLANE MODE turned on? that's the only thing I can think of that would be blocking bluetooth on stock. If thats not the issue then your only other choice I could suggest is a wipe data/factory reset from the recovery menu, which will wipe all your apps but usually solves software issues.

Try a factory rest
You wil lose all data but this usually solves the problem

before doing that, try wiping cache and dalvik-cache in recovery, for me that solved some problems i had with wifi, if it doesn't work, then you probably have to do a factory reset

Sounds like it's a hardware issue with your WiFi/Network chip

Yep, that was the first thing I tried, clearing the cache and factory reset, but no go. My last option was to re-flash the stock rom.. Took awhile to find the rom since I have the Canadian variant, with SM-G930W8. Re-flashed and got the wifi working again!

Settings Has Stopped

I just got the latest Android Oreo Beta update last night and since then I can't get in to my settings. Anytime I try to enter settings from anywhere I get an error that says Settings Has Stopped. I have wiped cache and I entered Safe Mode and the error was still there. Has anybody else had any luck with anything else. I am getting desperate.
Thank You

Conflicts of data.... If you can backup your photos/contacts etc with a good backup app and then do a factory reset.
I can back up my data using Smart Switch correct?
A hard reset did fix my issue. Thank you.
