Hi, all!
I have JXD s7100B and when I changed custom bootscreen (only the last one. I can't find others to change them ), because there was a circle on the boot image, I've noticed that the image is deformed - when turned to lanscape mode it is "squished" verticaly. After that I've noticed the same with the icons on the launcher - however I rotate the screen shorter side is squished. I have an idea that maybe display is not WVGA (800x480pix) like it's set (and sold) but a WVGA NTSC (854x480) so I would like to change 800 to 854 somehow but leave 480 and dpi. I've searched forum and net and 90% of posts are changing dpi with LCD Resolution app or by editing build.prop but nothing I found says anyting about what I want to do. I found some resolutions in /system/bin/set_display_mode.sh but I've decided to ask first if someone knows what I should do. Can you help me? Can I change one dimension with some app or by editing some file?
hi all i want to know that what is the benefit of changing dpi od screen. i checked lcd density modder but i m afraid will it help in savind battry of yes then how??
No it does not help you save battery. It lets you see more things at once by making everything smaller. It is a "high res" effect.
Hello
Can i change dpi stock 240. Someone have tested?

A solid-state screen's DPI is a physical attribute, you cannot change it.
I believe OP is referring to the soft DPI settings in build.prop. You must root, then edit the ro.sf.lcd_density setting in build.prop. It's already 240 on CM, not sure about stock though.

You are talking about PPI, not DPI
Stock DPI is also 240.
But why would you want to change that??
If some app is not displaying to your satisfaction, it's better not to modify build.prop, because it could lead to unexpected weird behaviors.
Better is to use the "Xposed Framework" with the module "App Settings"; there you can specify individual DPI settings for each app. The safer and more flexible solution! I use it without problems on all my devices.

You have it backwards.

As you didn't specify whether you want this on stock firmware or an AOSP ROM, I'd suggest to try the PACman port to the XTZ, as it includes per-app DPI modifier. It's currently in nightlies and no fully stable release as of yet, but it's worth to try if you really need that feature.
DPI = Dots Per Inch
PPI = Pixels Per Inch
The reason we've started to use PPI instead of DPI is because of PenTile, since that technology yields more pixels than dots per inch (dots are shared between adjacent pixels). Both are properties of the hardware but by telling Android you have a different DPI you can scale the UI. This procedure will make graphical elements that makes use of their physical size on the display (rulers, printing tools, etc.) show up at incorrect sizes.
For example, if you have a virtual measurement tape, you'll need to multiply all values with the original DPI divided by the new DPI. So if you choose to change your tablets DPI to 120, making every UI element scale to half of the original size, you'd need to multiply every value by 240/120=2 for it to match up with the real world.
I hope this clears things up.

As I already said: No need to change firmware. Just install Xposed framework with App Settings module on rooted device, and you can freely modify DPI per app.
I just thought I would give everyone a warning about changing LCD density with "adb shell wm density XXX"
(only applies to us non-rooted users -- rooted users can edit build.prop on the fly)
If you change the density, and then decide to check out the other resolutions like 720p and 1080p, it will fully erase your set density and return to stock resolution, even if you change the resolution back to stock (WQHD)
I myself didnt know this. I thought it would keep the resolution and recalculate the density, or reduce / increase the density based on the difference between WQHD. This is not the case.
So for those who set a custom density, DONT CHANGE RESOLUTION!
how can i change dpi or screen resolution of android
Root + DPI changer app. This can break some things. On some phones it can cause bootloops.
