*Google Calendar's event's drag'n'drop functionality* stopped working... again, after nearly exactly [two years since previous report](https://android.stackexchange.com/q/204158/20449) . Tried to restart both Google Calendar and phone itself (Motorola Moto Z2 Play with Android 8.0.0), cleared app cache and then data, without any results. I did very little to my phone before that happened: * no configuration changed, * nothing actually doing with my phone. I have only installed one new up -- FakeStandby -- as suggested [here](https://softwarerecs.stackexchange.com/a/76642/8327) , but since this app has nothing to do with the calendar itself, I would be surprised, if that would be a source of the problem. To clarify problem: _On a day view (not: agenda) long-pressing any event now brings no effect. Previously it caused an event box to be risen up visually above others, and moving finger around screen allowed to move event to some other hour or day. Now, drag'n'drop functionality does not exist / does nothing._ Is there any know report about some bug, bug's regression or is this a generally known problem? Or is this again my stupid phone going wako in exactly the same way during second anniversary of the moment, this problem appeared for the first time? **EDIT**: _From what I have learned, when Calendar becomes "locked" (no event's drag'n'drop) all items in calendar are visually more flat than usual. When functionality "returns" they again become a little bit 3D-like._

I use the adroid stock-browser and I'd like to play chess using e.g. http://www.shredderchess.de/schachproblem-des-tages.html Unfortunately you have to drag and drop the pawns. I tried several gestures, but I was not able to use the drag and drop feature. Do I have to change any options (where?) or should I use a different browser?

I've tried three different folder widgets for Android 2.3, but I noticed none of them supports adding applications via drag & drop, like the native folders do. Is that even possible to do? _I guess it isn't, or those application would be pretty stupid not to support it, but you never know._

*Samsung Galaxy Ace 2.* I set vibration to activate only in silent mode. I am **not** in silent mode, and yet when I drag and drop a widget from desktop to desktop, or to trash, on each drop phone vibrates. How to stop it, i.e. how to disable this kind of vibration?

Currently it takes me two steps to uninstall one application - go to application list and drag and drop it onto the bin icon. I dont like this way since it requires me to look for the application name from the grid listed. Is there other ways to quickly drag and drop it directly from home screen?
