I have updated to latest ROM. Update rather large but installs fast. Share experience here.

About reported issues:
Very large VOLTE1 Button in Status bar since 20161025 - Did not experience this
Change from WiFi to 4G don't work since update to 20161025 - Did not experience this

I have not experienced any issues so far.

I will leave it for now. "If it aint broke don't try and fix it"
My phones running great at previous update so no need to do this yet.

Something is consuming a lot of battery usage and WIFI disconects but never seems to turn off

I can confirm a faster battery drain. For me battery is working around 38 hours instead of 48 hours now. The biggest battery user in statistics is WiFi now (38% now, was much less before).

Switch from WiFi to Mobile Data broken.
And no direct comparison to 1011 but WiFi indeed using alot of battery.
Beginning with 1011 "WLAN AHB ISR" consumes a lot.
Research shows it might be connected to Multicast or ARP

After the update:

1. change the mac address of the phone, so i had to change it on the router too (i use mac add filtering)

2. some menu points in the settings menu change from hungarian to some slavic language.

My WiFi power consumption sits at 18%, guess it was a bit lower before. We get 7.0 update soon hopefully with bugs fixed.

It seems that the official ROM 20161025 contains a "potentially unsafe application". After reading about this in an other Board I tested the App ESET Mobile Security & Antivirus. With a deep scan I got this warning:

“potentially unsafe application“ in

It seems that ADUPS, the company behind the FOTA update App, have a big security problem that already get used to steal different kind of user data. On their Website they suggest manufacturers to patch as soon as possible: http://www.adups.com/article/show_article.php?id=168

Premium apps like McAfee and Eset report false positives, especially on Blackview apps. For example, McAfee reported that BV Wireless Update was a threat and was associated with a trojan.

But how can you be sure that it is not correct? The company that created the FOTA Update mechanism is talking about a security problem on their website.
