I'm using ZTE Blade III with custom port of CyanogenMod 11 (Android 4.4.4)by KonstaT. Here:

Yes, Opera Mini is (almost) fully functional, except Opera Link option which doesn't work since the last update (OM for Android v 7.5.3.)I've posted details here: https://forums.opera.com/post/47538 I'm not worried about that line in log, though it looks strange because I've never heard about that permission before?

--- This option (circle)shows only blank, black rectangle. Other than "Flag this", what options does it hide?

Yes, dirgas, I've checked that too. My Wi-Fi is stable and fast.

For me, Opera link/sync doesn't work properly since the last update. For example, after bookmarking page in Opera Mini, it appears on MyOperaLink page and in Opera desktop after few seconds (using Sync now button), but Opera Mini fails to load links already stored (from previous version) in Opera Mini dir on server. I keep less than a 100 bookmarks in that folder and I'm not sure why it takes so long to sync over high speed Wi-Fi. It's been more than an hour over Wi-Fi now, and the sync icon still hangs in the upper right corner.
@ nowurtalkin - Agreed! I do not expect from Opera servers/browser/team to take complete care of my data neither. I back it up regularly on a hard storage. Anyway, I like to use sync option to keep track of my activities and to have all those fav pages under one roof. Pure harmony, just like in "real" opera, huh?
To conclude on this subject, although I use custom ROM (custom port of CyanogenMod 11 for ZTE Blade III), it's the first time in 5 years that Opera Mini fails to (properly/fully)sync data between my home PC and my phone. Bummer!

@ nowurtalkin - First part - No, nothing like that. I've never changed browser platform nor I even tried to mess around with bookmarks in other browsers I'm using. I keep 'em all in Opera 12.17 for PC an Opera Mini for Android phone. Guess I'm getting older. Funny thing, I haven't lost ANY data, it's ALL here in Opera on PC, it's ALL on Opera link page. Simply, Opera Mini is not loading those bookmrx from the assigned folder on server. BUT, I wasn't aware of this: "...that numbers approaching 100 or even less, sometime caused a problem & a new folder had to be created for some folks." This gives me an idea. I'll be back with the report.
Second-about bug reports - I'm not sure I'm following your thoughts... Do you mean there's never been correct respond to those reports or people who's complaining never make one? Or both?
I can upload log with different buffer settings and priority levels, set to record only Opera Mini activities, but that's pretty much all I can do at this point.
Third part-reset and login - Again, no. I'm pretty sure I've never misspelled my user name and password.
Yes, I tried to re-log in on both Opera platforms, no result.

Anyway, thanx for chiming in discussion. I DO remember your user name from previous version of this forum.It was interesting discussion on a few subjects.
P.S. I'm on 4 posts, AGAIN?!?

Yes, device is running on custom port of CM 11 and everything works fine. No, I didn't add any plug-in for Opera Mini. Odd thing, when I log in on Google Play from my PC with the same account I'm using on phone, Opera Mini isn't listed in my apps. With the GP app on phone it's listed as installed app and I'm able to rate it and comment. Not from my PC, though. I don't know if this is related to error from the log I posted or maybe related with the Opera link problem I'm encountering since the latest update? https://forums.opera.com/post/47538

Edit: I just checked from 3 different browsers, same thing. I guess it's a server issue?

This looks strange. Anyone heard of this before? Thanx!
P.S. It's a real info, taken today with LogcatX. This is just 1 (and only) "alien" line.
