DPI Settings

Bought a Galaxy Tab S 8.4 LTE 2 days ago. Beautiful device with great screen, but:
First thing you realize is the small font size in several apps, such as Facebook. Barely readable.
Tried to use larger font size in settings. That did some effect on some fonts, but no consistent result.
Same with the Big Font app - font sizes and overall appearance becomes inconsistent.
So the only way seemed to change DPI Settings. Which required rooting.
I did the CF autoroot thing. And fiddled with DPI settings using Texdroider app. Originally was 220 DPI. I tried 420 DPI.
Unfortunately after reboot, I was stuck at "systemui angehalten" error message, and touch screen did not respond to input.
Unfortunately I could not switch off the device (to reboot), pressing power button for ever gave no effect.
Since you cannot remove the battery on this device I had to let it run down completely over night. Then booting into Recovery (or Download Mode) was possible again.
Tried a full wipe in Recovery an rebooted. But endless systemui crash loop remained.

Will try to re-flash via Odin to get it back working.

So this thread is firstly a warning if anybody wants to change DPI settings on the Tab S.

Then some questions:

* Did anybody overcome the small fonts problem by changing DPI and which DPI setting is advisable?
* any way to force reboot in such case?

Just use xposed module appsetting to set the dpi for apps individually.

AppSettings works well.. I changed the overall DPI to 240 because all the fonts were way too big for me.. I then reset certain apps back because some of the stock apps don't work right at different DPIs (camera, etc).

I have rooted my galaxy for using exposed framework just to be able to use app settings! It then works great. You can set the font size (or dpi I guess) individually for any app. I use different settings ie for Gmail, Facebook messenger, Chrome, Tapatalk... You have to try a bit to find the perfect setting but it's a must.

Without you have tiny fonts!

ok, I installed xposed framework via its installer and then added the app settings module. For those willing to follow this route: you find instructions here: http://www.xda-developers.com/androi...sed-framework/

Then it is possible to set DPI (or change font size) for each app individually. Text size and rendering was fine for me with 400DPI for Facebook, Tapatalk, or Nova Launcher. Tried with some other apps as well. Seemingly all look better and are more touch friendly with DPI >= 400. For comparison: stock DPI is set to 320 while real DPI is some 500+.

However it is rather inconvenient to set up each and every app individually via app settings module.

Tried to change the global DPI settings with build prob editor, but that somehow did not succeed, 320 DPI remained unchanged.
Tried with DPI changer to no effect. DPI cannot be changed via these apps. Very strange, have to investigate further.
Then tried again with textdroider, just to check - and device hangs again
No chance of rebooting or anything...but...yeah, found a trick: insert a SIM-card into the slot and then get asked to restart! Works. You can boot into recovery or download mode. Will try with adb to restore the build.prop backup...

Meanwhile - has anyone been able to set global DPI to something like 400-500 successfully? How?

Appsettings module is the best option,going in to build.prop is for overall and sends you in to a boot loop .be sure to have a backup

@edan1979, I found only one line in build.prop indicating DPI settings. build.prop editor and DPI changer strangely cannot change that.

I did another test, changing DPI by editing build.prop with Root Explorer. It does change - and goes into UI crash loop

@jball, any idea, why it crashes?

Unfortunately I don't, I just know what happened the first time I did it.

Appsettings is the best option though
