Removing Facebook app from Android
After a decade of using iOS, I've recently changed to Android. I can't seem to uninstall Facebook App, rather only disable it. Seemingly it's a built-in app (wtf?), but didn't I have to download it first? I'd like to remove the app as it's too data-consuming. Please help me to uninstall it on the Samsung J7. 31.217.26.62 (talk) 00:29, 3 July 2018 (UTC)
 * Some Samsung devices have Facebook app pre-installed as a system app. So, it can not be uninstalled, only disabled. Ruslik_ Zero 20:34, 3 July 2018 (UTC)

Wikipedia preview on Google and Bing
When one searches on both Google and Bing, one is presented with a preview of the Wikipedia article at top right of the results page. I have noticed an odd difference between the two in the case of David Lloyd George. Google calls him "Former British Prime Minister", Bing "Former Chancellor of the Exchequer". Now, both are true, but it is as PM that he is more famous, and he was PM after being Chancellor. Do we know why the two search engines give different short descriptions?

 * It is a wrong place you posted at. You should go to Wikipedia:Help. They will take care of it. Alternatively you can make the change yourself. AboutFace 22 (talk) 15:12, 3 July 2018 (UTC)
 * Err no - Wikipedia Help is not the place to explain why two external search engines give different results. AS for "make the change myself", I don't have that level of control over Bing. DuncanHill (talk) 15:15, 3 July 2018 (UTC)
 * It's not a preview of the Wikipedia article. Only a text paragraph ending with "Wikipedia" or "en.wikipedia.org" is quoted from Wikipedia. We often get blamed for errors in the other parts and made HD/GKG and HD/Bing for the purpose, as well as HD/YKG. PrimeHunter (talk) 19:31, 3 July 2018 (UTC)
 * I'm not blaming us for their errors. I'm asking how they come up with the short descriptions and why they differ. DuncanHill (talk) 20:50, 3 July 2018 (UTC)
 * Did you read HD/GKG? They are not Short description and are not taken from Wikipedia but from an unspecified source or a combination of search results. They are different companies with their own algorithms and I see no reason to expect them to come up with the same string. You could try a guess by Googling . Many results describe him like that, e.g. a 2017 book called David Lloyd George: Former Chancellor of the Exchequer. You could also try looking at the html source. Google says: . I don't know whether this contains a hint of where they got it. Bing says:  . That doesn't leave room for a potential source hint.  PrimeHunter (talk) 22:28, 3 July 2018 (UTC)

getting circled Arabic digits to display properly
I typed up a passage in Arabic, with circled digits, and at first they displayed properly. Then, one day, the digits appeared outside the circles. It doesn't matter if I change fonts (I was using TNR), and I get the same result when I post on WP as I do in LibreOffice. However, if I double the circle, the digit(s) will appear in one of them:



Well, sometimes they will. Even with copy&paste, sometimes the digit(s) will appear between the circles. (Right now, both here in the edit window and in page preview, I see the 8 in the left-side circle above.) I assume the problem has something to do w forcing LTR/RTL, with the change in direction of Arabic numbers compared to letters, but I have no idea how.

Oh, in this

orientation, the digit is reduced in size, as if it were in the circle, even though it appears to the left of it.

Hm, in the search window of my browser (FF), it displays properly. I suppose it could be an update to TNR that introduced a bug, but according to the MS website for TNR, there haven't been any updates.

Any ideas? — kwami (talk) 19:06, 3 July 2018 (UTC)
 * I wouldn't even know how to start to get what you're doing and I know a fair deal about computers. I suspect that editors on the Language reference desk might be more help. Dmcq (talk) 12:17, 6 July 2018 (UTC)
