Default LCD density

Here is something you newer footers may not have known you could do with root, change the LCD density to make your phone screen appear a higher resolution.

It is a simple hack of the build.prop. Using root explorer out are looking for the line "ro.sf.lcd_density=240" you will then change the 240 to a lower number. Keep in mind this may affect how some apps look in a bad way.

When doing this hack please do not drastically change the density at once, go down by steps of 20 or less per reboot so you do not have issues upon boot.

I personally like 185 for AOSP roms using launcher pro and I think 209 or 210 is best for sense roms but I am an AOSP guy so I could be wrong. I am attaching 3 screenshots of unedited build.prop files and 1 screenshot of an edited one.

I thought this was common knowledge to most? I've been doing this since I had my Eris. There's as an app that will do it automatically

Those of us with extensive root experience probably already know about it but many people here are new to android or rooting and likely don't know about it

How is this just NOW being posted. lol. Been doin this for the longest, Im a 190 fan. Great write up Yeahha.

Yes, there are apps that do this, but its easier to do it through the build.prop file.

It is one of those things that those of us who have been rooted for a while don't think about needing a write up and those who are new to rooting didn't know they could do.

I agree why bother with an app hoping it gets it right when you can go in and change the density quicker with just root explorer.

LOL. Jeeeeze man. TC for me removed the need for Root Explorer and ES took the place of Astro, but TC does the same thing that Astro and ES do on top of Root Explorer. All in double pane madness!

ES has the bluetooth file thansfer for me and I have an android mp3 player that has no market access so that is helpful. I think astro has the function too but ES was the easiest to get set up. I personally like the GUI more on astro than either root explorer or ES so I just stick with all of them. Sure I don't want an app to change my screen density but I want several that all do the same basic functions

May want to add not to drop it too drastically at once, and it may bootloop a couple times before the ROM loads. Its normal, don't panic.

Drop it 20 at a time to help avoid issues.

I could see it now "I want one pixel per icon! NO MORE NO LESS" , or would that be someone else on the forums...?

I went the wrong way the first time I changed mine, I was like -><- perhaps I should have read more...

yes,please add this to the posts... last thing we want is a bunch of " i tried to adjust my screen density and my phone exploded " posts

also id like to add,tho i do agree it may seem somewhat unneccessary to keep an app on your phone whose results are accomplishable with a simple build.prop hack,please keep in mind that you guys have been doing this a long time. its easy for inexperienced people to fudge things up in root explorer,and tho they prolly cant do anything thats unfixable,it can cause alot of fustration.

different users have different comfort levels of modification,and i would not discourage anyone who is imtimidated by the idea of modifying system files with a root file manager to simply just download a density app. theyre only a few KB in size and its not like the TB is short on internal memory.

OP and sticky both updated

I would encourage new rooters to try to use a file explorer to edit the buid.prop instead of downloading an app, the app may not work with all phones. Also with anything that modifies something in your root you should know what it is doing in case you need to undo it, or it could do something that boot loops your phone. Just like part of the reason it is encouraged to root via the manual process learning what different parts of the root of your phone are also help people feel more comfortable in navigating around and could be beneficial if they try to do another hack that doesn't have an app linked, like fixing the market thumbprint on some roms

Font changer is a good one that allows screen density changes as a bonus.

But you are on xda as well (and rootz?) Many people here might not be willing to search those sites and may not be as adept with technology as you are

I'm one of those new rooters. I assume I can change it back to original if I don't care for the effect. I'm a little fuzzy on what this actually does.

Yes, say you want to try it at 200 and don't like it just change the line in the build.prop to 220 reboot, then 240 reboot and it is back to how it was before you did anything

There are several in the market, I personally do not know the names, it looks like "Font Changer" can another may be "LCD Density" It may or may not work for any phone, but the build.prop edit should, you do have to be rooted to do this even with an app.

OK, so I found the file in the system folder, and found the line of text to edit, but how do I edit it? It won't let me do anything b/c it says it is read only. Do I hit that "mount r/w" button at the top of root explorer screen?

you have to click the bottom in the top right that say r/w or r/o. No offense, but if you don't know that you probably don't need to be messing with your density, to each his own though

That would be correct.

Come on worm (be nice ) root explorer auto saves the non-edited build.prop so if someone screws up they can restore it. Not to mention most people should have at least 1 backup and a rom zip on their SD so if they screw up too bad they can fix the issue.

It has nothing to do with being mean or nice, it's reality. If you don't know your basics you shouldn't be screwing with your build.prop, IMO

I can agree with that, but if someone is so inclined to screw around with what they don't understand and know they can't screw it up that badly then I see no reason to try to stop them. Part of how I "learned" how to manipulate my phone was trial and error.

Agreed and so did I and I wasn't trying to stop anyone, I just gave my opinion. If he couldn't figure out how to allow write permissions on his own without posting, maybe this is something he doesn't need to try is all I was trying to say. There is plenty of time to play trial and error with your phone, we all did, but we also knew the basics first

Well, I wasn't really going to mess with it. But hey, don't I get any credit for guessing the correct answer? I just wanted to make sure with you guys before i actually did it. Besides, I've got everything backed up.

OK, as I understand, if I want to run a sense 3.0 rom, I'll need to do this to get the screen to look right. My question is: will a nandroid backup save me in case I mess this up, i.e. will it revert back to the original value if I restore my backup?

Honestly, as long as you stay under 250 and over 120, youll be fine. I know a couple people that have run at 140. Looks like shit imo, but it works.

But I am correct in assuming restoring a backup will erase any changes I have made?

ATTENTION ALL THOSE THAT CHANGE DENSITY!

The new market checks density size of your phone to see what apps your phone will be able to run. Im a BIG fan of a higher density, I usually run around 185, and this serves me well. Granted some apps do NOT scale properly, but its the ones that for me dont matter.

As of late Ive been having issues with updating certain apps that my phone is currently running like Flash, Firefox and Lookout. Ive been buggin Zig to fix the issue, but then today like getting kicked in the balls by the baby youre holding, I was given a sharp reminder of that change. lol.

Now Im updating everything that Ive been missing out on the last few weeks and saring this with you all. So from now on if you see "This application cant be used by your device", its your density. A quick revert to 240 will fix this. Simply set it back after you update or leave it as is. Ive yet to play with any other densities to say what the min is, but I will and then Ill report back. Unless of course some of you would like to chime in with your density and ability to update.

Heh that would explain a lot as to my issues with not being able to update. I figured it was something to do with a thing I tweaked but didn't think it was the LCD density. I wonder if we drop it low enough if it would allow us to install some tablet only apps?

I think it might actually. Yep, just searched for the Swiftkey Tablet X and it shows that I can download it. This is a really stupid check imo.

Update on the Density issue, I changed it to 220 and got the device incompatible issue so, if its not set to stock, you wont be able to update your apps, which is a big pain in the ass from the market. Trev is looking to see if it can be disabled.

Woot woot! Ziggy fixed this problem. I can now update anything and I have no checking to see what my density is. Ill be posting it on my site in a second.

Alright Thanks to Ziggy and Trev, the market no longer searches for LCD density. Grab it off my site. I posted the stock and blue themed versions.
