I wanted to know since the tab has a screen that is 3x as big as a Galaxy S (3 phones put side by side on the tab) is there an app or a home launcher or something that will allow me to have multiple things running on different screens.
For example, I need to take information from one document and organize with another and I can easily switch between them on Windows and Linux.
I then need to tag along to other places and want to continue to edit both documents on my tab, I have to keep opening one document then remember a sentence or piece of information for a second and close that document and open the second one to continue typing it up.
It is a real hassle and very time consuming and frustrating. Our tabs are pretty big and I would like to utilize it to the fullest of its capabilities as a tablet/big smartphone.
What my suggestion is if anyone feels like making an app that I can do just this and more on my tab, they couod design an app that works like the home screen.
For instance you open a document, email, or webpage and want to look at another document or note you made for yourself or another email. All you do is swipe to the left or right and it is a clear home screen or something to that effect or maybe a list of documents, notes, emails, webpages you can open. You then choose/open what you need and can continue with the first page having the second one open for reference or whatever the case may be.
You can then easily switch between the 2 or however many pages you have opened just by swiping the screen just like you would your homescreen.
If someone knows of such an app or had the resources to make one please let me know.
Also this would make for a great multi-tasking app if made correctly.
What might be an issue here is that most programs themselves are going to detect the loss of focus and handle things. Either saving/reverting to front screen/closing down completely, or leaving things up and running.
I can see what you're after, more a 'cards' type thing, and it might be possible, but you'd have to override what the OS is sending to the apps (don't send the lose focus thing), or get the apps to handle things differently.
Either going to be impossible, or trivial. And even if it was possible to be hacked, apps are going to be assuming their running and might use more power. The way it works at the moment is to assume you're being shut down, and handle that gracefully so you're using minimal resources on a phone.
If one were to change how android handles the multi-tasking, would this sort of app be possible?
Another question is, are there any document editors that can do something like this?
I have an iPod Touch and an app named iFile, and it has multi-window type thing that I am describing where I can open many pages and view many documents at a time.
That's the main thing I want it for, editing documents without having to open and close constantly.
I was thinking of this the other day. This would be something you'd have to build into a ROM. It'd be a nice mod, and since Android already takes screenshots for the recent apps bar, it wouldn't be too hard to implement once the source is released. My thought is it would be a four or five finger gesture left or right. It could possibly zoom out similar to how the screens zoom when you drag an icon on the launcher so that the other tasks could be visible at the same time. The normal activity lifecycle would continue as usual (i.e. onPause() would be called as soon as the gesture starts, and onStop() once the activity is off the screen). A screenshot would be used in place of the actual Activity until the gesture is over (meaning the Activity has "snapped" into place).
Hi everybody, I would like to make a list of those features that lacks on windows phone, even if we are only at very early stages, maybe with the arrive of unlocks some of them could be added, in future..If you have any suggestions I can edit the list
P.S. I consider the GDR3 improvements alredy achieved (like a decent task manager, FM radio..)
-A FILE MANAGER
(yeah, I know that on the market already exists something, but they are definetly FAR from a real file manager. Anyway nokia/microsoft said that in the next months would come out http://www.tuttowindowsphone.net/wp-content/uploads/2013/08/nokia-lumia-file-manager.jpg , we will see..)
-FLASH PLAYER
(on windows RT exists and works, as in future the WP8 kernel would be almost the same of WinRT, probably we will se it..or at least I hope so)
-LIVE TILE TOOGLE
(Right now we have only shortcuts to settings, would be more useful if the live tile would act directly as a toogle. Maybe someone will give it an attempt :fingers-crossed: )
-A NOTIFICATION LED
(some phones does have the windows logo acting as a led, BUT it works only to notify some battery status (a bit useless..). If it should be used as a proper notification led would be amazing..or at least the camera flashlight could be used for that (ok, this is a desperate suggestion LoL)
-COSTUMIZABLE RINGTONES AND ALERTS RELATED TO THE APP
(A different sound for whatsapp, sms and e-mail. I personally use the phone at 90% in vibration/silent mode, But I know that it could be useful)
-A CUSTOMIZABLE LOCKSCREEN
(I mean lock-patterns and some other useful features..I mean, windows phone 8 lockscreen can be used better, you know..)
-A QUICK WAY TO MANUALLY ADJUST SCREEN BRIGHTNESS
Sometimes the Authomatic sensors don't work well and is necessary to switch the brightness manually.
-A BETTER PUSH NOTIFICATIONS MANAGEMENT (thank's to @Life'sGood for reporting and to @GoodDayToDie for explainations)
Sometimes are delayed
This really belongs in General; it is neither a question (or answer) nor related to troubleshooting.
With that said...
The only thing really standing in the way of an on-device file browser is the need for somebody to write it, but that doesn't mean it'll be worth much to do so right now; until I or somebody else gets more permissions working (ideally, all of them), the amount of the file system which is readable (never mind writable) is extremely small from an app's perspective. To get an idea of what I mean, take a look at my Webserver Native Access app - the all-capabilities version, if you have a Samsung phone - and see for yourself just how little of the system is accessible.
Even completely leaving aside the permissions issue (ha!), Flash player support is somewhat unlikely. First of all, it struggles a little even on the Surface RT, which has nearly twice the CPU power of any WP8 model right now (GDR3 opens the path for quad-core WP devices, but they aren't here yet). Second, the kernel may be the same but the user-space libraries are not; a lot of system components that Flashplayer depends on are probably missing from WP8.
Believe me, such toggles have been attempted, and they will go on being attempted. It'll happen eventually...
Some phones actually have a notification LED, even. There are (unofficial) APIs that could probably be used to control it, too... I wouldn't hold your breath on this one, though. In any case, you won't get colors unless there's actual multiple color elements there to work with; the best you could di is different flash/fade patterns.
Update 3 (GDR3) brings some additional controls over notifications. However, I believe you're right that they still don't offer per-app sounds (though you can set the sound for apps, as a class, I think).
Lock patterns are pretty darn weak and easy to break, but in general I agree with the concept of having more control over the lock screen, and additional features.
Not a problem that I've had, but I can see how it could be. This probably falls under the toggle tiles request, actually; have the ability to create tiles that increase or decrese the brightness.
Sorry for the bad section, I was looking at the same moment at general section and at Q&A and I chose the wrong browser tab, my fault (don't know how to change section)
Anyway thank you for the reply I think that the main problem for indipendent developers is time, because every 18 months windows stops the support on the actual OS and switches to another new (WP8 support is planned to be killed in july 2014, after that it will be an update to extend "phone life" of 6 months, in total: 2 years). After that date will come out another OS but nobody knows if it will be "similar" to WP8 or something totally different (probably the latter option)..and everything probably would start from the scratch. I think that all the OSs producers are making BIG efforts to make you change phones after exately two years LoL
P.S. When I talk about brightness control, I can't figure out how a live tile could directly make it (swiping on it?), it can only turn on/off. My idea was that could be useful something like a swipe on the status bar on the top of the screen, like cyanogenmod does (I don't want to compare android to windows because they are totally a different concept, so I generally don't want to mention functions present in other OSs that could be ported, IMHO it's quite useless thinking in this way.) but I suppose that this is quite impossible on a programmative side :s
You'd have two (small) tiles for brightness control, one to increase and the other to decrease. It would be a little messy and would need to go in significant steps, but it's possible.
I think it's not a bad idea I've just found out that on offical WP8 site exists a section dedicated at suggestions about features to add to windows phone, and many pepole voted on that site..but Microsoft NEVER listened to them LoL probably the task manager improvement in GDR3 will be the first feature accepted by Microsoft from that lists. Anyway the requests on the officiale site are quite the same on my post (file manager is STRONGLY requested)..nobody is asking for flash player or for led notification (quite strange IMHO but that's it).
P.s. any idea about how to reach bootloader (I'm talking about ativ s)? I suppose that with a simple boot is impossible, even pressing a combination of buttons will not work..
There have been multiple items implemented from uservoice, although the custom SMS tones and application closing are certainly notable for having been long-requested and taking until now to be provided.
No idea on the bootloader. I haven't been looking for it in particular, though; not my area of interest.
Technically, you can implement a media stream source to support flash (i believe there is one already on the interwebz).
However, flash is really not meant for mobile devices (which is why very few mobile OSes support flash out of the box), because it wasn't intended to be used on devices with such low computing power. So even if you were to have a flash player, you wouldn't be able to do much with it until your battery drops dead or your phone starts turning into plastic(or aluminum in some cases) soup.
There is also an increasing abuse of flash advertisement all over the internet (which is bad from many points of view), which hurt mobile internet browsing quite a lot on devices with flash support. I just wish google & adobe would stop supporting this dark ages format and move on to HTML 5
Yeah but..just to make a famous example, look at youtube. Many videos are locked down for mobile devices. Combining a flash player and a browser that supports desktop as user agent, you can go beyond this limit. Ok, the result is that it works quite bad, but at least it works..

I don't think that the format (flash) is the problem here, you can always watch these videos with an unofficial app, like Metrotube or Tunetube. And I doubt they use some kind of flash player, it's just not allowed on mobile devices by the uploader/youtube I think.
To the OP, what do you mean with "features that lacks in Windows phone 8", something MS should fix or hackers should provide as features? Because a file manager would completely be against windows phone's locked OS, every app is sandboxed and can't access other app's storage, which has its reasons for security. A file manager will never be possible, except for th case they change the whole OS. On iOS, it's pretty much the same, and with a jailbreak you get a file manager (if you want to). And you can brick the whole system, can make apps crash or even modify them, which would cause a lot of trouble for Microsoft.
I have to try those unofficial apps, I've never considered to use them Regarding the lacking of features I mean that with a system well locked down like WP8 is, I think that microsoft should put more effort to provide some features that nowdays are considered basic (you know, a notification led is useful and doesn't require any particular effort from microsoft or manufacters. Even (real) toogglers are essential but they are not in here..don't know why ) Of course I understand that not all the features can be provided by microsoft due to security reasons, and here comes developers' work
P.S. regarding file manager I suppose that, if it will would ever come out, would have been thanks to developers, but as I said in OP, nokia probably would provide it. Don't know if it's true, but let's see what comes next! Some hours ago at Abu Dhabi, at lumia phablet presentation, came encouraging signals to encrease the number of the apps for windows phone. Ok, it doesn't mean anything and Personally I don't use instagram but more apps means more people that will adopt WP8..and more people will call more developers (hopefully) and micosoft ecosystem would finally start (even if there's to solve the "problem" of Windows RT/Windows Phone, first).
As you said even iOS is closed-source but (even if I don't like making comparisons between OSs because they aren't meant to work in the same way) I think that the interest in that platfom made possible to create the powerful mobile substrate, to make even heavy modifications to the system.
But even without moddings, I mean..iOS now has quite al the essential features that a phone requires (quick and real toogglers, a camera flash that tries to act as a notification led..ok, not a file manager but it has a download folder, a quite "useful" lockscreen, battery percentage..), so IMHO is quite usable out of the box because apple now provides many of the basic features expected to be on a phone. So I think that for apple devices jailbreaking is not as necessary as was in the past. WP8 on the contrary strongly needs a jailbreak because is not a fully mature OS..
ANOTHER FEATURE THAT LACKS (IMHO): the new versions of office are not as useful as office 2010 in windows mobile. Who remembers WM, office 2010 was so similar at the desktop version (even fonts could be changed and added!!!)..but since then, the most part of features disappeared, so office mobile stopped being as useful as it was before for business people nobody will care about that (developers can't do anything for this, and microsoft will never provide those features..but I miss it. So I didn't put this in the list because it's more a "personal" thing.
And I was thinking that even a windows phone with the stylus would be useful especially with one note, that on PCs and tablets is ready to be used with a stylus and I found this fantastic. But even this is a "personal" desire that will never come LoL

Why? I don't think I'm that wrong, there's no real possibility to have a fully featured file manager on WP, is it?

In my inner eyes i see next user/professional developer asking if there was a patch to adjust screen brightness to personal needs in more than just the dictated three steps.
Answer: Buy an other phone or program your own OS.
A very simple feature is missing, App update notifications from Store.
WP8 now doesn't seems to be telling me when the apps on my phone has been updated unless I went to look for them. Its only then that the tile shows 1 update available. HELLO???!!!
So that means I have to list out the apps I've downloaded and look for each and every single one of their updates?
How can Microsoft and OP miss this one out?
And my clock isn't synced even if I set it to auto, sometimes it jumps AM/PM or even months!

@Life'sGood and @gigsaw: That's a problem with your phone, not the OS as a whole. I guarantee you that WP8 fully supports app update notifications and clock sync. If yours doesn't, that's a problem with your phone, specifically. Blaming Microsoft for it is nonsense and won't help you fix the problem.
Now, as for fixing the problem... do you have an active SIM card in the phone? If so, does it have a data connection? That's most logical reason I can think of for the app update notifications to not appear; no connectivity when the phone tries to check. The clock can sync off the towers as well (also needs a SIM, I suspect) but it can also sync off GPS satellites (which have extraordinarily accurate clocks, and broadcast time signals that anything with a GPS receiver can pick up even if it can't get an accurate locations fix).
The most likely solution, honestly, is to hard-reset your phone. You might want to call support or take the phone in to a Microsoft store or something first, though; hard-reset will wipe the data (though that's most likely what they'll tell you to do anyhow).

Please let me explain why I though it was microsoft's fault: I had an WP7 with a different SIM (but same phone number) and those problems were there for almost Every app I had to update and clock often changed hour. After that I had an Android, at least with date and time no problem..with store of course I can't say after a year of android I switched back to WP8 and the market/time problems happened only a couple of times..but I thought that was something wrong in my phone because here on xda nobody has never talked about it. But I notoced that even whatsapp sometimes misses or delays some notifications with wp8 (with android never happened), and, at least in my country, this is a common problem with many users that complain abouth that, so at least for whatsapp I'm sure it's not my problem. I contacted the support of whatsapp and they said to me, if I remember well, that whatsapp notifications pass trough Microsoft servers, so in their opinion the fault of this problem was microsoft's. So I was thinking that even the other problems are related with Microsoft server's sync..so when another user said to have almost same problem As mine (but As I said, with WP8 happened to me only a couple of times, I don't know if other user has those problems more often), I convinced myself about my theory LoL of course I can imagine I am totally wrong because I don't know how those syncs works and if they work alla in the same way..what do you think about it? Before re-editing the OP I wanted to explain to you the whole situaton because you have for sure better knowledge about that
Push notifications for apps are completely different from update notifications. The latter are polled for, by the OS, at pre-determined times and without the app in question being involved at all; you'll get the update notifications even if you've never run it.
That said, push notifications on WP (7 or 8) are not as quick or reliable as on Android, it's true. The battery impact of push-using apps is lower, though.
Thank's, anyway I will hard reset my device. I have just realized right now that if the glance screen could be ported in future on other devices, a led notification becomes useless (of course, I don't know what is the battery impact on an AMOLED screen..and it's VERY important)

afaik i'm not seeing these features. I did a hard reset but I've yet to see the Nokia Camera, network+ (call filter) update.
I googled and found out this is a system wide issue with almost everybody having this issue. So does a half f'ed apple still counted as an apple?
App update notification this feature is simply not available.
I have a SIM and data connection for my 1020, on Wifi most of the time. Clock doesn't sync at all neither.
Hey guys, random thoughts/rant for a software idea.
I was thinking of the next evolution of the Intent system on Android. I always thought OSs seemed to spend almost no effort on integrating softwares on it. It was almost like an afterthought every time. Android was a huge step in the right direction. The next step would have to be very definitive, and backwards comparable of course. It would have to be something users want, and make it easier on the developers as well.
This system would be called something along the lines of 'Sentence'. It evolves with developer and end-user choices and, if I'm right (here's the big pitch, would have the potential to make software measurably more stable, secure, efficient, and user-oriented without really changing any behavior on the developer's side. Of course it has the same potential to be stagnant, but I think the users would punish (unwittingly) developers who lagged behind or didn't put in the effort.
The sentence system allows a user to build a sentence to discover not only the correct application, but an infinitely specific task before ever encountering UI. It is reminiscent of auto-completing sentences in Google Search. An example is the quickest way of demonstrating. The [] specify user interaction and ** specify user choice (probably a button press):
I would like to
[*send*] [search] [open][...
[a][*multiple*][...
[2][*3*][4][5][CUSTOM][UNTIL...
[files][emails][smss][*pictures*][...
[*to*][GO][...
[emily][drake][*george*][...
[*and*][GO][with message][...
[emily][*drake*][george][...
[and][GO][*with message*][...
[CUSTOM][*check this out*][...
[*GO*][and]
this immediately opens the camera app for exactly 3 pictures. Once the 3rd picture is taken, the UI informs the user that the next action is about to take place. After a short time out, the 3 pictures are sent to George and Drake. After the first shot, the user can shut off the screen or pocket the device knowing the timeout will occur and then the task will continue. Being an OS-level function, the user can trust it regardless of the app.
Unless the app task fails. If Apps that use this system can't provide tasks that don't fail, they will become unpopular far quicker than the tasks that do fail that users just deal with anyway.
Furthermore, many apps can be published virtually without any UI at all, significantly cutting down on development time and allowing the dev to focus on the task and functionality.
This could turn around voice activation as well, since the user quickly understands the routine task format to get the best results, and would be more confident to provide far more complex long-winded sentences that the OS could understand perfectly to the detail.
While some sentence lines will be defined by the OS, the developers and users alike will be able to define the evolution of the sentence tree. Developers will make the smart decisions, while the users will crowd-source the popularity of each possible route. The most logical and/or common sentences would quickly be the norm. If the OS prioritizes specific routes over general ones, then developers will be incentivised to make their apps as task-specific as possible as well as as task-plentiful as possible.
The losers in this quickly become apps that use ads, apps that rely on 'convincing' the user of something with UI, and of course utility apps. Of course, this brings back the main reason for 'pro' apps: functionality. The pro version will have these features. The free version will only have these.
There wouldn't be a way to exploit the system or flood it. If the functionality doesn't work, the app becomes not only intrusive and annoying, but offensive to the user as it promised a specific task and performed something else entirely. Those apps simply wouldn't survive.
Of course, application for this kind of thing would have to be imposed by Google et all for it to exist, but there is another way. It can be implemented as a shared library that provides the necessary interfaces and cache all the necessary information for other compatible apps. That would work for a full implementation, and I can't see any features that would be missing. Backwards compatibility would still work just fine, as the app would simply fit existing intents into this sentence tree as well as it can. The sentences would simply end up being smaller. The best part is that with the right effort, this sentence tree could act as an 'Intent builder' for existing android apps. I bet I could build a handler for the tree that would get me through the above demonstration with the standard Gmail app using known intents. See where I'm going with that?
I would build it myself if I had more time, but I'm def interested in helping (or instructing) anyone who would like to take a crack at it. I think if someone got this idea into Cyanogenmod, we'd have a pretty huge win, and Cyanogenmod would have an incredibly unique UI gem to show off to stock users.
Honestly, I see no way that a system similar to this won't be built and become the standard within a decade. It would be trivially easy to build as well although some of the decisions to be made might not be so easy. So yeah, that's it. Rant over.
When developing an application for desktop windows, there's always a way to access functionality - sometimes through back doors like the registry, etc... I'm developing an application for Windows Phone 8.1, but there are certain pieces of functionality that aren't exposed in the PRT APIset that is available to me. For example, we want to ensure that the user has password protection on the lock screen when using the application. There doesn't seem to be any associated APIs to readily use. So my question is, are there back door ways to do such things? How? Is there a way to access ALL system settings - like a registry or something of the like?

Another question would be - if something like intune can enforce lock screen password policies, shouldn't I be able to do it the same way that intune does it? If so, how? If not - why not?
It's not possible to check if user enabled lock screen password or not as far as I know
but if you want to made your app secure (because it may include important data)
you can create a password for your own application !
I did it in a little notepad app my password page allow user to set a password with all English and Persian Characters , numbers and special Chars like [email protected]#$ and etc.

It's pretty easy to check, using the registry, but at least in 8.0 that's not allowed at all for store apps (your app would get rejected). I don't know if the rules changed for 8.1. There are ways to sneak past the store checks, but they could pull your app from the store if they ever found out. I know of at least three ways to access the registry APIs (4 in WP8.1) and two of them are pretty hard to detect unless somebody checks for them specifically... but they're the kind of technique that malware uses, so such checks may be in place.
I don't know what InTune is doing, specifically - I'd need to pull the app apart to see - but there are special application capabilities (not normally available to third-party developers) that can query and even set policies. Apps without those capabilities will get Access Denied if they try to use the same methods though, and normally you can't add those capabilities to your app.

Thanks for this great and detailed information. See, that's exactly what I'd do if I were developing a desktop app - since i know that intune does it, I'd figure out how intune does it and voila. I'm finally getting over the idea that the same methodologies apply to windows phone development.
For my own educational purposes (since I want to understand this platform better), I would really like to know specifically how you go about accessing the registry APIs (for example). If there's any way for you to describe any number of these methods, I'd greatly appreciate it. Thanks again!
My NativeAccess libraries (check my signature, or search on the forum or on Codeplex) contain an example of one way to access the registry. The code is open-source; you may use the libraries as-is (don't expect to get them into the store, though I won't stop you from trying), use the source code as a reference, or modify/build them yourself; the license is very liberal (MS Permissive). The functions I use are generally documented on MSDN, in the desktop APIs section; the phone has the same functions, although the DLL names are changed and the header files hide them.
