How to revert back from a LCD density change - Android Q&A, Help & Troubleshooting

As the title says, I tried to change the LCD density on a tablet which resulted in a boot loop. I can access adb and an adb shell to rewrite the density in the build.prop, however this does not seem to allow the tablet to boot. Is there anything else I can try? And are the values stored anywhere else? The tablet runs on jellybean and is quite new so there are no recoveries/firmware files out there. Thanks!

[Q] LCD Density causing notification led to not go off????

I have lcd density installed and have set it to 220, which is below the default 240. After applying the settings and the phone reboots, my notification led turns green and stays on even when I lock the screen. When the screen is locked the led light is dim and when it is unlocked it brightens back up. If I reboot the phone or I reset the density back to default from the app, it goes away. Why is my phone doing this? Does anybody know why it does this? Is this really because of lcd density??? any and all responses will be greatly appreciated!
TIA

I had the same problem, haven't messed with density but it just seems random.

I would believe it was random but the only time I have this issue is when I change the density and as soon as I apply the default thru the app it goes away or if I reboot the phone... I think whats happening is that the sdcard, both internal and external, are not being unmounted and remounted properly in the reboot process from the app... Thanks tho...
Seems if I just wait for more than 30 seconds( Figuratively ) the notification led goes away....
I get this all the time its quite annoying

All you have to do is wait for about 2 to 3 minutes and it goes away.... I have seen it take longer at different settings... I am running it at 200 now... At 210 and 220 it seems like it took longer to go away...
That also happened to me so I downloaded droid overclock and there is a Lcd density changer inside that app and it works great. Maybe you can give that a try

Do you have to reset the density after every reboot or not? Because if you dont that would be awesome!!!

On the Droid Overclock app, you just have to set it once and your good to go. I done multiple restarts and the Lcd density does not change until you change it inside the application. Hope that helps.

I don't know which version of Droid Overclock you have but i have version 2.1.2. Inside the app, i went to extras, build properties, and then LCD density. If you need version 2.1.7, its the link below. Its the first link.

Simulate Screen Size?

Is there a way to simulate a specific screen size when running an app? I am getting a MotoActv and I want to try apps out on my Atrix before throwing them on the Actv. It has a QCIF+ screen and naturally not everything is going to work on it (but Angry Birds does!)
So is there a way to spoof a specific screen size when launching an app?

Maybe changing the screen density on the phone with "LCD Density" from the market, Unless someone knows what to mess around with in the files of the app itself.

Dragon Touch y88x screen replaced with lower resolution

Just wanted to leave it here, incase it would be useful for someone.
So, i have this cheap y88x Dragon Touch 1024*600 tablet for my kids and it was working fine when the other day it was dropped and the LCD was broken (touch was working). I tried everywhere but couldn't find the compatible LCD (no model number etc, one was found but that was like £22) but after few weeks i got the one on aliexpress which looks compatible.
Long story short, that screen turned out to be 800*480, which messed the keyboard, touch and everything else.
I was sent the latest firmware Y88X-XZ-V5-AL-TZX-20150326 (dragontouch support is good and fast) which was easy to open in Dragonface-2.1.2.
There i changed the sys_config file, changed the lcd_x to 800 and lcd_y to 480, left the touch screen to 1024x600
also, in build.prop added following lines
Code:
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,ad
b
Saved the image and using PheonixUsbPro, applied the img. Right away the systemui started to crash but i was able to access adb (run kingo tool if adb not connecting, you dont have to root as its aleady rooted).
change the dpi to 120 using following command
Code:
adb shell am density 120
And thats it. Everything came back to normal, the touch was picking up correct points, the UI looks ok, kids can play minecraft etc etc!

Did you figure out how to extend the battery life. Mine is 13 hours max?
Sorry of topics but you seems like Sony's McGuyver to me.
Whoa.. I cant thank you enough for this tip. Never knew changing of DPI is so easy without root. Everything looks so hi-res now. Seriously, everyone should do it. Sony should had done this be default.
Only glitch I see now is the sony home launcher's page indicator is a little misaligned.
I already tested and tried as your instruction. However I revert back to 480 as the phone feel warm and I afraid it will explode anytime.
I just noticed that the battery life is affected... or is it just me? also the phone is way too hot when I'm using it. hotter than when the DPI is 480
I not sure what wrong. Density and battery should be no connection. You phone is hot because many background processes is running. Try end task all not using app, I think it should be back to normal very fast.

I reverted it back to the original and it's not as hot as it was. I think and sure it was affecting... come to think about it, if the icons are smaller, then it can accommodate more things on the screen thus making the gpu work more in terms of animation but I don't know if that's right. But it did affect my battery life when I changed it.

Technically yes it makes the gpu work a little harder to draw more things on the screen. But there shouldn't be any noticeable impact on the battery nor heat. Countless other devices changes their dpi but never or hardly were this reported. There should be other factors causing the issue for u.
Is there something between 480~320?
Sent from my E5533 using XDA Forums
So if we adjust it to make things smaller to look like a real 1080p, will it effect gaming performance? I mean fps drops?
apps problem...
i have a problem. i mean there is a problem. i set density to 320 and after that i tried to install minecraft pocket edition v13 b5 which i have taken it from original density(restore). it didnt install it. just gave an error.
Edit: i dont know why but game performances are increased.
is it not possible to do it using terminal on the phone itself?
I dont think so. It needs root i guess

Looking for this as well... 480 is to big while 320 is quite small.. Any idea if we can set it somewhere between these values? Thanks in advance ..
May I request someone to post screenshots after increasing the screen density? Thank you very much in advanced.
You can pick any number you want. I use 360. Just change and try it out until you find a setting you like, you won't break anything.
different between 480ppi and 320ppi
320ppi is smaller, 480ppi is bigger

Changing DPI. Adb.

Hi, has anyone tried to change dpi using adb? Can it be done without messing up the top of screen by the notch?
