Android Tablet Density settings - Android Software/Hacking General [Developers Only]

Hi everyone
So, I have this Android Tablet called the Haipad M701 which runs on Android 2.1
By default the icons and everything are HUGE, doesn't look too good So, I rooted the device and found a density setting which by default was at 240. I changed it to different values between 160 to 240 and with smaller values it looks very nice
BUT at any value other than the default 240, almost ALL apps and games are no longer in fullscreen
Does anybody know if there might be a fix for that?
Thanks

wow... not a reply since sept... not sure if you get it fixed or not.
one step you can try is to turn off the compatibility mode in your tablet.
this should fill up the whole screen in most apps except some apps that written specifically for small screen phone without adding large screen display mode in it.

[Q] Raise the dpi

halo
i don't see so well and the Resolution in the one s is to high to me
i raise the DPI Through rom toolbox to 260
but i get some error of the system ui "Unfortunately system UI has stopped"
for example when i enter to "recent up" i got this erorr and i can't enter there....
there is a way to fix it ??
thanks
If I'm not totally wrong raising the resolution will result in smaller letters. You should lower it instead. So please try it.
And you can change letter size within settings -> display & gestures -> font size. By default it is medium, so you can change to large or extra large.
At least under accessibility there is an option named TalkBack, which will activate a spoken feedback to what you touch, choose or activate. I hope your ability to see is not that bad!

I just checked that out.
What's with the notification about it "collecting" info? Collecting it where? And what? I didn't go any futher.....
Tomney,
I am not sure if this will actually work but if you have root you can edit your build.prop file. In that file there is a line that refers to ro.sf.lcd_density. By adjusting that number up or down you can change the dpi of the screen. Now that does not necessarily mean that all of your apps or even the Sense UI will work correctly, but it might be worth a try.
If you want to easily do this I would download the BuildProp Editor app from the market.
Haven't tried it on this phone, but at least on every sense Rom I've used for the hero changing LCD density has always messed up everything. One of the reasons I allways used aosp

as i said i did it with romtoolbox. it is the same , i raise the dpi to 260....
it makes some problems with system ui and i got some errors
i now replace the rom to miui and the dpi change doesn't Affects the system ui
dpi change can be on a rom without htc sense ui and i think even regular ice !
but..... now there is some problem with the market because Resolution Compatibility i think... there is some app i can't download .....
for now i need to come back to 240 dpi for download some apps and its Annoying
maybe if could change the Resolution to Exactly 800\480 i wouldn't get the market-app-Compatibility issue but i dont know how... maybe someone know how to do it?
my vision isn't so bad and i know the regular options aka font enlarger Etc ...
dpi change is the best choice for me .

[GUIDE] Increase android gaming performance (resolution change) (ROOT NEEDED)

Hello everybody, and before all, sory for my english
The main objetive of this thread is to provide a guide to increase performance on high density screen GPU bound devices, for example, the nexus 10.
The last year android devices start shiping with very high definition screens, but without the necesary GPU muscle to make them work good.
Since I was a PC gamer, I know the terrible impact of high definition on the gaming performance, and, on this screen size, this is a useless impact, since the extra resolution are practicaly unperceptible.
The past week I spend a lot of time trying to change my device's resolution (a nexus 7) and with kernel modding, it is posible, but don't are great since I only play 1/3 of the devices usage, and the 1280x800 resolution are great for chat, browsing (or posting on the forum ).
Finally I find a great program that allow me to temporary change the display resolution of my device, and with the free version I was allowed to change resolution to 720x450, and on gaming performance, that was a GREAT performance updrade, even, with the wuality sacrifice (and on a 7 inch display, this wasn't a great lose.
In order to do that, I need to disable soft keys, since they bug A LOT with the resolution change, and to use a custom launcher because the default launcher bug too (go launcher ex is my favourite and the only one I test).
So, I leave a guide on how to prepare your device to use this mod to increase gaming performance, and to provide help to everyone who want it.
First of all, you NEED to be rooted.
Now, start with the device preparing.
Wee need a soft keys replacement, I recomend this one, work great and are really simple to customize.
https://play.google.com/store/apps/details?id=jun.ace.piecontrol
Now, you need to remove the soft keys in order to gain extra screen space and to protect yourself from potential bugs on the user interface.
To do that, you need to edit your build.prop with an editor or manually with a text editor and add this line.
qemu.hw.mainkeys=1
Now, on the next boot your device have the soft keys disabled.
To protect the status bar from being bugged, we need to change the lcd density of our display in order to allow a phone status bar (the phablet one bug on low resolution displays, and on tablets without sofkeys, we need a status bar.
To do that, we need to edit from the build.prop editor the "ro.sf.lcd_density" parameter and set it to something above 214 (nexus 7 have 213 and it enable the phablet interface, and on 214 it enable a full phone interface, but with small icons and more work space, you need to test and find the most usefull dpi for your device)
Now, we need to install the "magic app", and start testing resolutions and trying to find the most confortable for us, I have the paid version and use on the nexus 7 (16:10 or 8:5) 480x768 since it allow GREAT performance improvement and a good image quality for my screen size.
https://play.google.com/store/apps/details?id=com.nomone.resolution_changer
One example of a game that work GREAT with this trick is N.O.V.A. 3, on the tegra 3 plataform it is almost inplayable, and with the trick, on my nexus 7, it looks like this.
So, start testing this, and post your results, configs and devices.
Help us resolving the screen resolution fragmentation on devices!
And mods, please, help the post with a good language correction XD
Edit: Changed the APK link, to a new one, the new app have onscreen buttons to fix the navbar problems, so, pie controls are no longer needed, I leave the link here onlfy for people to know another alternative, thx for NoMone Devs!
i am planning to buy a 7 or 8" android with high resolution and was a bit worried about gaming performance because of the high resolution.. can you post a video of the performance gain plz?
Whoa! I might give this a go when I get home. Good Job.
i am interested for feedbacks in other heavy games like modern combat 4
this!
what android device and other mobile devices lacks.
there's no setting to set the resolution!
people out there always suggest me to change the dpi, but hell no!
"dpi" is not physical resolution, it just changing icon and other ui element to small or big.
this terms confuse many people.
they think DPI is the screen resolution.
and.... i just cannot understand the hype,
many vendors put high res 1080p on 5" device?
what the heck!? is it necessary?
what's next? ultra 4K res on 4" screen?
come on.. it's unnecesary and waste of battery.
gpu works hard to get the job done in that resolution. especially gaming.
thank you for sharing this trick for us.
google should consider to put resolution changer on the next android.
and android vendor should realize put hi-res on small screen is just plain dumb.

It's hard to take a video without a camera, but to give youman example, on 500x800 asphalt 7 give me 60fps on the shangai track, with my 800x1280 default resolution, I have 20fps aprox with a lot of fluctutations, it's a great app, and with GMD hide buttons, is almost perfect.

Yes, on the HTC Desire 480x800 display, you need to set it to something lower that it, for example, 360x600, it increase the gaming performance, this trick work great on high res display like the nexus 7 or nexus 10 displays for example, try to reduce the resoution to something that retain the original aspect ratio and be lower that 480x800, 360x600 or 240x400 make a grat change, but im not sure about image quality on this device...

ok thx i have tried to set it to 360x640 on the free version.. but nothing happens.. it just say "Display scaler free has been granted root superuser permissions" and nothing happens
Mh, maybe this is a device specific issue, have you posted a review or sended the autor an feedback email about it?

Hey I bought the app and it works fine i tried most of the resolutions and even a custom one but it seems that no resolution lower than my physical one will go full screen i always get black borders do you get this too?
thanks a8 soc
I tried tweaking my resolution to a higher one yet nothing happens on my Alcatel OneTouch T10. Any fix on this?
Sory for the lazy responce, I have so much time working and other personal things I read on the store that the apk only make the new resolution use the full screen on 4.2+ so if you are on 4.1-, you have it with black borders, sory, but I cant do anything for this :/
is there any way after change resolution for fix buttom touch key(it doesnt work physical touch key)? or any idea where is touch key config file or something like that related in root?

I don't know, I suppose, android mao this keys as a touchscreen surface or something like that, the most easybway is using gmd hide softkeys and with it, trigger a softkeys quick navbar and play with this, I am using Paranoidandroid right now and with the pie controls I fix all my problems, and on smanager I created 2 scripts to execute the commands to change resolution, one for the 500x800 for gaming and the other to 1280x800, the default resolution of the nexus 7.
Try it and leave me a comment with your experience.

Thanls for your reply.i have mtk quad core 6589T 1.5 ghz device with powervr 544MP1 and 1 gb ram . My screen is 1080p. i think gpu cant handle this resolution sometimes occur wierd lag and some highend games cant playable.After change resolution to 720p and 320 dpi everything perfect games performance increase %80-100 even memory consumption decreasing.(100mb).i am using with pie control but i want to using continiusly 720p i think after change resulotion touch key coordinates change over screen size.if i found that responsible cfg file or something maybe i can handle this.i am still searching..

For me, the way to go is sticking with default res for everything except gaming, as I say, I have two scripts on 2 widgets on my main screen, one with the commands
su
wm size 500x800
And the other with the commands
su
wm size reset
on jely bean 4.3 this commands set the override resolution of the screen.
on android 4.2.x the wm have to be replaced with am.
The app launch this terminal commands and override our resolution, but since I cant buy the app because of credit card and legal issues on argentina, I made my own scripts with smanager and swidgets . Quick on the fly change, and "letz rack!"
i am using this fantastic program on my thl w8s to scale resolution from 1080p to 720p during games and the speedup is fantastic...i set tasker to autolaunch the app when i click on the game icon, and once finished the game just click on fixes/reset resolution to bring everything back to 1080p . this program is great and the only one i have found...let's hope the developer doesn't abandon it and keeps making it better....and with a better integration in tasker maybe

[Q] ro.sf.lcd_density changes density but still no multipane layout

Hi,
i got a Nexus 7 (2012) unlocked and rooted. And an app which supports multipane layouts for tablets. Like most of the time the layout on my Nexus 7 is the phone layout.
I changed the ro.sf.lcd_density from 213 to 160 and everything is smaller than it should be but i still get the phone layout instead of the tablet layout. Not only in that specific app but also in basic views like the android setting. Since right now i'm only intereseted in this app to give me a tablet layout i tried xposed too, but didnt work. even setting the density down to 70 didnt work.
i tested it wich my nexus 5 too. there i do get the tablet layout when using a density of 160. so there aren't multiple apk files for different devices.
Is there anything i can do to get the app display in tablet layout.
would be great if someone can help me

Display size menu option

On my OnePlus 3T and my S7 Edge, there is an option in the Display settings that allows me to adjust the overall display size. It will reduce or increase the look and size of the entire display (smaller text, icons, menus). Does anyone know if the Mate 9 has the same menu, or anything similar?

If you enable that developer options, there is an option labeled "Smallest width", changing that will adjust the dpi and scale everything smaller or bigger.

FYI...The bigger the number, the smaller everything gets. It's the opposite of changing the density in the build prop. I personally like to leave my display size at large and set the smallest width value to 500.

In the settings menu, you tap...display then tap view mode. Then you can choose large, medium or small. I personally like changing the smallest width in developer settings.
Maybe is it possible to get tablet ui working here? Tryed to change dpi through dev options, but nothing, if i even set it to 600.
On Nexus 6p, i put that on 590 and had tablet ui in apps working.
You can just change it in the display mode setting no need to mess about I have it on small

I could get a quasi tablet looking interface for gmail app using a dpi of 800. By tablet looking interface I mean that, besides the usual list of emails, some of the options you get by swiping to right from left edge were present on the screen without swiping. For example I now had the option to switch email provider, (from gmail to aol) without swiping. The problem is that changing dpi to 800 hosed "settings". It would crash if I tried to open it. Fortunately the dpi did not stick when I rebooted. For those that use Dolphin browser, by changing dpi to 480 (from the default 432) you can get a 4 by 4 grid of icons for speed dial (instead of the 3 by 3 that comes by default setting of dpi).
Personally, I would not want my global dpi to be 800. I would just want certain apps to run with higher dpi. Normally I do this with the Xposed module App Settings. But, as AFAIK, that is not possible on nougat at this point. If someone knows how to modify an app to change it's individual dpi setting please do chime in!

Question Is it possible to get low DPI on most apps, while having default on things like Tiles.

So i really like the DPI at 200, it means I can see more than 4 lines of a text message and dont need to scroll for days to get to options in most apps, but having the GW4 on dpi 200 is a mess, the tiles are just shrunk down and attempting to work in the top left quarter of the watch while sometimes elements from them(like weather) will try to centre making things overlap and ruin the visuals.
Is there any way I can have my low DPI without having janky tiles? am I just choosing bad DPI numbers with the ones I have tried and that is what is causing it? Preferably id like to be able to choose the DPI per app but I assume that isnt possible
Let me put it this way. You use android smartphones for some time, right ? At last 8 years, right ? Have ever seen in any android phone dynamically adjusted DPI per app ?
I'm not sure if it's possible to change DPI per app via ADB, but you should be able to decompile each APK and manually set the DPI in Android Studio. It could be a lot of work if you want to customize a lot of apps, but it's an option if it's important to you.

I am not shure if it is move in the right direction. Lets say you rework app to 100 dpi BUT display will still work in 200 dpi. So the visual will be distorted.
This is not Windows where app can set display of the monitor to required resolution.
I don't know per app but you can increase or decrease all on your SW4.
