[Q] Use android phone as a secondary desktop - Android Q&A, Help & Troubleshooting

Hi
I want to use my android phone as secondary desktop.
I connect my phone to a larger display using HDMI out or miracast and connect it to a keyboard and mouse via bluetooth.
But all the icons and the web pages are too zoomed as the dpi isn't automatically adjusted. The browser feels too zoomed in so the does the office app.
I found an app by name of secondscreen ( https://play.google.com/store/apps/d...een.free&hl=en ) which does the same for me. It changes dpi whenever an external display is connected but for it to work, it requires root.
Is there some other way by which I can do the same without root. Like whenever it is connected to external display , it changes dpi to 160?
The main problem I face is in 2 apps: browser and office. So if the overall dpi of device can not be changed then can these 2 apps be forced to run at this dpi. I don't mind if they become unusable when opened directly on phone but they should be usable when opened on secondary display.
The last option I have in my mind is to run linux on android and then dpi fixes on its own, but I somehow haven't been successful in running linux without root on my phone (maybe something wrong with the custom rom I have installed so gonna try it out on a stock rom soon)
So I have 3 alternatives
1. Change DPI of the device to 160 without root ( need to figure out a way for this)
2. Compile apps to run at a particular forced DPI so they work properly when connected on external display ( not sure if this can be done either)
3. Run Linux without root on android phone ( still trying it out )
4. ???? any methods you guys wanna suggest

any help on this?

[Q] Turning my legend into a mp3 player

Hi, I've got a new phone recently, and I'd like to turn my old HTC legend into a mp3 player.
I'd like to completely remove Android and just make it a file manager similar to an iPod Classic, so I can play audio and video files.
I want the file manager to be the ONLY program on the phone, exept being able to take pictures (althogh the last is optional)
How do you do that/anything similar?
Thank you.
I don't think removing Android fully and using the phone with just a file browser is an option, I might be wrong though.
Your best bet would be to run CM7 without the Gapps package, this will probably be as light and fast as your going to get.
MoPhoACTV Initiative
Well, I don't want it to be an Android anymore
I did something similar with my old Motorola Droid. I wanted it just to be an Audible player, so I installed CM7 and just disabled as much as I could. With root access, you can remove a number of system apps without breaking anything, and then use something like LauncherPro to hide the rest ot the icons in the app drawer that you don't want on there. You can also make a dock at the bottom in LauncherPro that has nothing on it, so that you can't even get to the drawer without adding an icon for it in the dock. You would end up with a homescreen that just has whatever specific apps you want on it, similar to an iPod Touch.
It'll probably be close to impossible to get something working on there that isn't Android--the touchscreen/wifi/camera rely on drivers and such. Your best bet will probably be to go with a ROM and customize it to fit your needs.
If you've ever used the Rockbox firmware for various MP3 players, there is an Android port. This runs like a regular app on Android. Its compiled daily for Android here:

You still need an operating system, you can't just get rid of Android. You could disable stuff that isn't essential to the OS like Gapps, and any other apps you dont need.

[GUIDE] Things to do after rooting Grand Prime, focused on privacy setup mainly.

Hi people!
I recently rooted my grand prime and i want to share the modifications and tweaks that you can apply to your phone.
Mine is the G530FZ, but these can be applied to any grand prime, since this settings are generic even to other phones.
I am very interested in improve the privacy and the functionality of my phone, and some settings don't need root, but im going to share with you anyway since improves your privacy.
HOPE YOU LIKE IT
-----------------------------------------------------------------------------------------------------------------
Enable Dev Options:
Go to About this device, Compilation number and press it repeatedly until it says "Now you are a developer!"
Go back, developer options and tick USB Debugging to enable ADB over USB
-----------------------------------------------------------------------------------------------------------------
I installed Busybox, using Smart Install (Safest), this is important for most of tweaks.
-----------------------------------------------------------------------------------------------------------------
I disabled KNOX, SAMSUNG SUPPORT TOOL and bloats like:
-Play Music
-Play Kiosk
-Play Videos
-Drive
-Samsung Billing
-Play Games
-Galaxy Apps
-Google+
-Samsung Account
-Chrome
And some replaced by:
-Apollo
-FBReader
-MXPlayer
-
-
-
-FDroid (Open Source App Market, your privacy want Open Source!)
-
-
-Firefox
To disable knox and support tool connect your phone through adb or use the terminal emulator and type:
su
pm disable com.sec.knox.seandroid
pm disable com.rsupport.rs.activity.rsupport.aas2
The other apps can be disabled through settings/Application Manager.
------------------------------------------------------------------------------------------------------------------
I installed Xposed Framework, and then this plugins:
-The POWERFUL GravityBox [KK] (Interface and usability tweaks)
-XPrivacy (A privacy manager that lets you choose what information can be read by an application, asking you when the application tries to read something like contacts, use superuser, read messages and so on.)
-XPrivacy in App Info (Injects the XPrivacy settings in app info for the selected app)
-XHalo Floating Windows (Something like a window manager, lets you use apps in the way of windows or anything like that)
-Call Blacklist Pro (The name says all)
-App settings (To fix issues with the dpi change, I will explain it later)
-Xposed Preference Injector (To inject xposed plugins settings on the settings app)
-------------------------------------------------------------------------------------------------------------------
To control what applications connect though WIFI and what though 3G I used AFWall+, and configured it like that:
Mode: Black list (Block Selected) --> This can be done pressing the message that says: Mode: White list (Allow Selected)
On Options/Preferences/UI Preferences I unchecked LAN Control.
Then you can check the apps you want on WIFI, on 3G, on none of that, or unchecked for WIFI and 3G
The first time you need to go to Options/Enable Firewall, and every time you modify the settings press Options/Apply.
Is useful if you have a Bank application and you are afraid about ARP Poisoning on WIFI (Man in the middle) or things like that and you often connect to public WIFI's. You can block WIFI for this app, and let only connect trough 3G.
Or you can block data hungry apps to work only on wifi and mantain your 3G data usage on acceptable limits.
---------------------------------------------------------------------------------------------------------------------
I installed
-Performance Control (The performance app on AOKP I think o.o')
With this app i changed the DPI using the build.prop editor on the last tab, and changed ro.sf.lcd_density to 190
Then you need to use Xposed App Settings plugin to set the DPI's of this apps to 240, because are made to this DPI's and looks ugly, and some even not work:
-Camera
-Contacts
If you have any other app looking ugly after DPI change, use this fix, and tell us here
Also the pin numbers on lockscreen will move to the left, but it works, and if you change the DPI's of com.android.systemui the status bar and the notification bar will look fat... (o-__-O)
Don't change cpu settings, i did that and look that does nothing... XD
----------------------------------------------------------------------------------------------------------------------
Also, I am afraid about predictive keyboards and where they send what they predict, so I installed the only Open Source keyboard I found really useful:
-AnySoftKeyboard
It can be installed from FDroid or Google Play, I think that the google play edition updates often
Play a little bit with the settings to get your keyboard of choice, it can be tricky at first.
-----------------------------------------------------------------------------------------------------------------------
If you are really conscious about your privacy, you can search for the dev reports that apps send to the developers without your consent and disable it, if you don't care about that, this reports can be useful to some devs
And last, and the most conspiranoic app here:
-Android IMSI catcher
This app theorically warns you about IMSI stations near you. This stations are fake GSM antennaes with encryption disabled to hear what you hear and read what you send, explaining it quickly.
I don't know if this app really works, but if it works, and you have spyes around you, tell me if it works ;D
------------------------------------------------------------------------------------------------------------------------
Sorry if i wrote something wrong, I'm don't speak english on my country, I only know the english I learned from series, games and documentation
If you need some screenshots for any explained here, tell me
Cheers!

After rooting your G530 is booting normally?
To remove system apps Nobloat app is a option for users not familiarized with adb prompt & comand lines.
Nope, i need to install phillz recovery to avoid recovery on reset, besides that is working fine

Try Wipe Cache from recovery..if does not works, download stock rom matching ur phon csc and rom version from sammobile .. then flash it through odin, then re root... make sure this time u flash those two files with method exactly as suggested in the root post.if u get boot into recovery prob again then make sure wipe cache n then reboot.

@kentone, which method of rooting did you use?
Is it then KingUser or SuperSU?
Maybe you could throw a link to rooting manual?
one thing I'm happy about is using Greenify and Clean master to hibernate and block apps from autostarting, it leaves me with 320-380 mb free RAM most of the time, however if u add whatsapp and chat apps, you wont get notifications till you open the application which I personally prefer it to be like this.
I rooted with odin method, i have the reboot to recovery bug, but is not a problem for me, this is my 'production' phone and i will not touch it so much until we have cyanogenmod or something. Or when we know why the reboot to recovery bug appears o.o'
Sent from my SM-G530FZ using XDA Free mobile app
About greenify and clean master, throw clean master away and dont hibernate the apps with notifications like IM apps XD if you want more ram download kernel adiutor and put the memory preset on ''agressive'' or one level down that! Dont touch the cpu settings, it does nothing with this samsung rom u.u'

@kentone what if I dont disable the knox ? or what if it tripped ? what are the side effects ? and what is the purpose of knox? sorry I dont know that , and thanks in advance for your answer , I hope you will answer my question
In gravity box, cant able to change signal cluster look. Cant add day of week to status bar tweaks. Help me please. I have selected lollipop icons but they are not changing. I also tried reboot.
Amazing things you can do after rooting
Yeah but there are lot more benefits of rooting even though there are certain risks , . Most amazing benefit I think is we can remove bloatware and also block ads which is brainstorming though there are still deelopments going on in that field. Have you tried adblocker Browser??

Desktop space in Remix OS

So, I've been in the last row of Desktop space in Windows for years now, but it never really filled.
Programs were added, and programs were removed.
So, No idea how Windows deals with shortage of Desktop space. (I should find that out too)
But, my Desktop space in Remix OS filled within days. ANd I don't know how to increase it.
Should I uninstall or disable My Desktop and add a launcher ? (it being a system core app and all, probably not a good idea)
And anyway, I love Remix OS shortcuts, quick to access , easy to find. One of the many wonderful things I love about Remix OS.
So, how do I go about it ?
The Start Menu/App Drawer exists, but I don't want to be clicking that everytime I've to access something.

Help please

I w'd create folder and move some icons in it
I'll do that

In your screenshot I see apps like "Docs" and "Sheets". In other screenshots I saw app "Skype", too.
I can install these 3 apps, but on my computer (Lenovo T400) they do not run. One or two seconds after I have started them, they stop working and disappear from the screen. Other apps like Dropbox, Evernote, K-9, Firefox, etc. run without any problem.
Did you (or someone else) run Skype, Docs, or Sheets successfully on Remix OS?
Haven't tried Skype yet, but Doc/Sheets work fine.
Have you tried running them in fullscreen mode - ON ?
And did you download those apps from PLayy store ?

You can use Nova Launcher and its ability to group similar apps. See my post:
http://forum.xda-developers.com/showthread.php?t=3330231
I tried it on 2 laptops, on 1 (i5, intel graphics) everything runs fine.
On the other one (old intel processor, old nvidia graphics) it boots up but some apps (skype, antutu for example) just close right after starting. Also i can create folders on desktop buf i cant open them directly, filemanager just closes like other apps. However if i start the filemanager and navigate to the folder in there it works.
I also tried it on an intel atom (server board tho) runs really smooth on there but both onboard network ports are not working. When i go to ethernet settings it shows som (random?) mac address, witch doesn't belong to any of the network ports. I hope my network chip will be supported in some future release.

My Android box cannot run apps in background

I've just got a new Android tv box Vontar Kiii. Overall a very good box. However, the box cannot run any apps in background like other normal android device. It always kills app as soon as I press the Home button. This happens to every app I run. I have particular problem when I run Openvpn Connect, it will immediately disconnect as soon as I leave the app. This never happens to my other Android phones or tablets.
I'm not sure why the rom set to kill the apps and not allowed them to run in background at all.
The box has 2gb ram, rooted.
How can I make it behave like a normal Android device?
Thanks in advance.
Update: solved. I have to press back key instead of home key.
Up, i have the same problem...
UP, in the past i knew how to fix it, it was something in the built.prop if i remember right.
My old KIII doesnt got this problem i fixed it somehow but my friends one got the same problem...
Dammit can no one help, it was written here in the forum if i remember right...
Finally found it....
So you have to use a explorer with root access and delete or edit "allowbackgroundapp.list" located at "/system/etc"
I use to edit the list and add the names of apps i wanne run in the background, like "org.xbmc.kodi" , "tv.twitch.android.app" or "org.mozilla.firefox".
Actually pretty easy, hope i could

Unlock system on boot using custom keyboard

Hi,
I've acquired the G8 Power since my daily phone is not available.
I will consider installing LineageOS later if needed, but for now i want to stay with stock rom.
I never use anything like play store, maps, gmail etc...and tend to avoid using pre-installed apps, replacing every "standard" app like keyboard, contact etc...by one available on F-Droid.
The problem come with the keyboard, ive always used OpenBoard with Gboard disabled. Never have any problem with this behavior when on stock, until today....after settings everything, i restarted, and the keyboard was not available at system boot to unlock the screen...have to use an usb-a to usb-c adapter with my computer keyboard to enter the password.
Double checked OpenBoard was defined as default, its the case, and it open everywhere that need input (except screen unlock after booting, because after the screen was unlocked at least one time, the keyboard become available the next time screen is auto-locked).
Is this a problem on android 10 ? Or maybe a bug with OpenBoard ? Or simply the stock rom is not that good as i think ?
Hope someone have info about this thanks by advance
