[Acer Iconia Tab A100] crossix:
it might have been caused by a permissions change. I managed to do the same thing switching back to gen2 and figured out that my build.prop only had read permissions set for owner.. it needs at least read permissions for group and root
[Acer Iconia Tab A100] trusteelfan:
Worked great. Thanks for this
[Acer Iconia Tab A100] Wacko:
Hey guys i think the market compatability doesn't work for me. I copied the build.prop in my /system dir, my device is shown as a A500 in the settings and i cleared the market cache but i still dont find apps like friend me or the adw launcher. Any idea?

ok forget it my mistake sry
[Acer Iconia Tab A100] linuxman008:
Thanks for this, helps with app compatibility and speed. I noticed that some Games have issues though, cause me and my friend have this tab, and he bought UNO from gameloft, and is still on 3.2, works perfectly, speedy, correctly scaled, all of that. But when I downloaded the free uno , it downloaded and ran correctly (it didn't work at all before this mod), but had 70-80% of the app off the side of the screen (I think it downloaded the files that are scaled for the a500). Is there any way to fix this?
[Acer Iconia Tab A100] crossix:
The only way would be to play around with the display density and set it higher so that things appear smaller. I've thought about changing it to boost our tabs resolution, but not sure how well that would work (it may make some apps work and other that used to work no longer work.)
[Acer Iconia Tab A100] reid-o:
I added the lines: movFilter=40

mov Hyst=0

It seems to have helped with the touch sensitivity.
[Acer Iconia Tab A100] crossix:
I found those settings in the galaxy tab 10 thread and have been testing them along with a couple of other tweaks. I'll be updating the build.prop I've posted soon with my changes (just didnt want to crash anyone's tab before I tested it out fully).
[Acer Iconia Tab A100] reid-o:
It doesn't seem to increase the sensitivity per se. It just seems to help with quick taps and double press mistakes. That was most of my problem, so Im happy.

But I still had to remove my screen protector to get it feel like how I want it.

I use my ipad 2 as a gold standard. It got closer, but it's still not as consistent.
[Acer Iconia Tab A100] crossix:
For me it helped scrolling taps (where if you were scrolling a page with ads and links it would click them at random.)
[Acer Iconia Tab A100] reid-o:
I've actually tried it with the value at 0. I don't notice the hypersensitivity that the users experience in that thread.

Lower seems to actually improve things.
[Acer Iconia Tab A100] toyface:
Will be looking forward to this Crossix, the prop improved my tab, especially the internet speed and consistency.

Is there any way we could change the system font on the A100? I've fallen in love with Roboto on my Nexus and my Linux Desktop.
[Acer Iconia Tab A100] sikesjb:
+1 on the permissions.

I set the permissions before rebooting on my GEN 2, and had no problems with bootloop.

Thanks.
[Acer Iconia Tab A100] crossix:
have you tried this?

https://market.android.com/details?id=com.martino2k6.fontchangerlite&hl=en
[Acer Iconia Tab A100] aznmode:
+1. This is what I used to change font on my Evo 3d and Acer a100. Roboto is nice but I just don't like how the fonts in email looks the same with read and unread mail. Could barely discern the difference. Went back to stock.
[Acer Iconia Tab A100] toyface:
Great find you two, used to this back in my Desire days, I seem to have forgotten all about it. I'll try this when I'm home.
[Acer Iconia Tab A100] Icewyng:
Have you considered adding something about the SDcard read ahead speed?
[Acer Iconia Tab A100] bizarre.static:
do i have to be rooted to do this?
[Acer Iconia Tab A100] bjones72751:
Yes, system has to be read/write (aka rooted).
[Acer Iconia Tab A100] crossix:
You can't fix the read ahead speed with any build.prop mods, but If your using my sdswap mod it's built in to it.
[Acer Iconia Tab A100] conorkickass:
I have files on both my Internal SD (all the data and stuff) and on my external.

Do I need a blank external for this to work?

What copy operations do I need to do after the patch?

Thanks! :)
[Acer Iconia Tab A100] crossix:
you don't have to wipe either one, just copy the contents of your internal (/mnt/sdcard) to your external and then do the mod in the op.
[Acer Iconia Tab A100] conorkickass:
Oops, I wasn't paying attention and had meant to post in your Memory-swap thread. Your above advice is true for the Memory swap mod?
[Acer Iconia Tab A100] crossix:
Yes, I kinda figured you were talking about the sdswap.
[Acer Iconia Tab A100] PoorCollegeGuy:
Hello,

This thread has been featured on the XDA Portal

I've always been a big fan of build.prop tweaks

:)
[Acer Iconia Tab A100] aznmode:
Man what did you do? Now my touchscreen doesnt skip!!! Was there a difference with this build prob vs last weeks regarding the touch? Using Touchutil I can see the touchscreen response as it should and doesnt lose contact with my finger 98% of the time. Thanks man. Now why did I get a Transformer Prime for again??
[Acer Iconia Tab A100] Icewyng:
How about adding this as well:

debug.performance.tuning=1

# Enable Stagefright helps stream Video and Music Faster

media.stagefright.enable-player=true

media.stagefright.enable-meta=true

media.stagefright.enable-scan=true

media.stagefright.enable-http=true

# Fix some application issues

ro.kernel.android.checkjni=0
[Acer Iconia Tab A100] bjones72751:
Are you getting any adverse affects running stagefright? I wasn't aware hc had stagefright.
[Acer Iconia Tab A100] Icewyng:
From what I can see, it still does work. So far, I have not had any problems with it. Anyone else tried it? Always better to have other reports to see if it works well for everyone.

Got a few more things I am testing as well. I did some GTab dev work and was wondering if some of the build.prop stuff I have used on it could help as well.
[Acer Iconia Tab A100] crossix:
Thanks for the suggestions, Ill add and test them in my build.prop to see if they work and give you credit for them in the op if they do.

Its good to see the a100 is finally getting some sort of attention, thanks for the add!

I don't update the build.prop file every week (only when I've completed testing for stability and to see if the mods I add actually do something (just because you add a mod doesn't mean it does anything or will crash your tab). In this case the mods I added in made a huge impact on screen responsiveness and accuracy (you should actually be able to use a stylus now).

So enjoy, Ill hopefully be releasing some other stuff soon. Im working to see if I can compile external kernel modules to possibly get usb host mode and overclocking to work based on what a dev did with the milestone, but I'm not sure yet if it'll work though.
[Acer Iconia Tab A100] illego:

Build.prop working great. Screen sensitivity problem is gone. Tablet has never performed better. Thank you.
[Acer Iconia Tab A100] notsointeresting:
I hate the way they said "its not on its last legs yet" like this device is just going to perish because it's horrible compared to other tablets even though it practically has the same specs as most 10.1 inchers. But its good they put it on the portal nonetheless

Anyway , whenever I use this build.prop I keep getting notifications to update. Is there anyway to disable it?
[Acer Iconia Tab A100] crossix:
Havent seen that issue before, have you tried turning off automatic updates? Also what build are you on? (you have to check your build number before doing this build.prop otherwise it wont report correctly)
[Acer Iconia Tab A100] RangerJay:
Same here. Also, previously it showed Android version as 3.2 and now it shows as 3.2.1.

I never had any of the issues with 3.2, such as playing music through the speakers with the headphones plugged in, but it never before showed that third digit in the version.

Also, under Device Information, everything is blank except SNID.

It says System Update is up-to-date.

Otherwise, I haven't done much testing so far. I was just pleased that it booted up fine and seems to be working well.
[Acer Iconia Tab A100] dharr18:
Welcome aboard Icewyng. Hopefully you haven't given up on the G-Tab. Although mine has gotten lonely since picking up the A100.

FTI, Icewyng did some great tweaks with the Viewsonic G-Tab. For me, this is an exciting addition to the A100 forums.

---------- Post added at 09:32 PM ---------- Previous post was at 09:26 PM ----------

The ironic thing is, the A100 was released after the A500.
[Acer Iconia Tab A100] captainreynolds:
OP - just a curious Android user here.

Did you also manage to avoid the Android Market's LCD Density check? For instance - if a device is not set to a certain screen density in the build.prop, some apps will be listed as incompatible despite the fact that they are not. Did you get past that? If so, could explain how - this is an Android hackers' most annoying problem...
[Acer Iconia Tab A100] crossix:
I only addedd the default density parameter in rather than changing it because of that problem. If who ever uses this mod that wants to change it for themselves I've added the values as comments. I personally dont see what the issue is, if market tells you its not supported just change the value to default, install the app and then change it back.
[Acer Iconia Tab A100] crossix:
It seems that the stagefright entries helps with the buffering issues the youtube app has, I had already included the preformance.tunning entry from the build.prop I worked on for the htc aria. It really improved this tabs accuracy. The android.checkjni doesnt really do much that Ive found, but it doesnt cause any probs so Ill throw it in. Thanks for the tips, if you find any more Ill test em out and put them in there with your name on it :)
[Acer Iconia Tab A100] Icewyng:
Glad I could help.

Stagefright really improve the playback on videos. I remember having a few more settings I was playing with a while back. I will look for those into my old Gtab build.prop.

edit: I was thinking about those settings:

ro.media.dec.vid.wmv.enabled=1

ro.media.dec.aud.wma.enabled=1

ro.media.enc.hprof.file.format=3gp

ro.media.enc.hprof.aud.hz=44100

ro.media.enc.hprof.aud.ch=2

ro.media.enc.hprof.codec.aud=aac

ro.media.enc.hprof.aud.bps=128000
[Acer Iconia Tab A100] crossix:
Those look like settings for audio and video recording and enabeling wma/wmv playback for the built in audio / video player I'm not sure what the defaults are for honeycomb but Ill find out.
[Acer Iconia Tab A100] toyface:
Loving the new build.prop. Have certainly noticed an improvement in streaming from YouTube. Makes watching and playing Minecraft nice and easy for sure!

Keep up the work Crossix, greatly appreciated.

Sent from my A100
[Acer Iconia Tab A100] crossix:
Icewyng gets credit for the youtube playback improvement, I just added it to the build.prop cause it actually worked!

Thanks again Icewyng for providing the settings!
[Acer Iconia Tab A100] Icewyng:
You are welcome. It is always nice to share your knowledge and experience with others.

I am still doing some more research to improve the build.prop. There are so many settings to play with. You can rest assured I will keep this great tab for a while.

If we could only modify the init file... :)
[Acer Iconia Tab A100] toyface:
Thanks for helping with this, your tweaks along with Crossix' are greatly appreciated.

I see nothing wrong with this tab, apart from slightly wonky viewing angles. It walks all over the A80 G9 all my friends have bought from PC World, for £10 less ha ha!
[Acer Iconia Tab A100] BigGunn:
Just switched to the newest build.prop. No change to my YouTube issues. My connection shows traffic, but it takes forever to load up even 5 seconds of video. In the browser it loads fine.
[Acer Iconia Tab A100] toyface:
I'm still curious as to why my app compatability is so poor. The bbc news app has been updated and optimised for honeycomb, so I uninstall, clear market data and try it. Still the shoddy phone version.

Any ideas?

Sent from my A500
[Acer Iconia Tab A100] crossix:
it may say its designed for hc, but that doesn't mean it supports our tabs native resolution. a good example of this is gscript.. looks fine on the xoom and my htc aria, but not on my atrix or this tab. It reverts back to the first "usable" size rather than trying to display at 1200x800.

Supposedly ICS will fix this issue with it's automatic scaling but I'm not going to hold my breath.
[Acer Iconia Tab A100] 22patryk:
Thanks crossix for all your work on A100. I am repeating this on anorthern post, but I really need some answers ASAP. After going from Gen2 to Gen1, updating to xxx.4 and changing to custom build.prop I have a problem with rebooting. Sometimes the unlock button gets stucked while swapping and I have to hold the power button to reboot again. Sometimes it just gets stuck while updating the clock, and I have to do the power button again or if I'll live it alone, it will go into reboot by itself. But, when it'll pass the start-up ok it runs beautifuly. Any thoughts about it? Also, in the device information, in settings, there is nothing except a SNID number.
[Acer Iconia Tab A100] crossix:
Modifying the build.prop file wouldn't cause these types of issues, sounds more like a permissions issue or a corrupt system partition.

If you didn't flash the full recovery and only flashed the Acer_A100_1.014.08_2.007.01_COM_GEN1 file, I'd highly recommend trying to flash Acer_A100_1.014.08_COM_GEN1 first. The 2.007 recovery only updates files that are out of date and may not match the original files that GEN1 stored in the system partition.

So another words your running a mixed build of GEN1 and GEN2, which could definitely cause some instability.

Using my modified build.prop will clear out the device information since we're actually disguising the tab as an A500 so that more apps show up on the market. Again though, it won't cause the type of instability your running into. Download and install vache's Full Package for GEN1 and then upgrade from there and you should see a big difference. Here's the link if you need it: http://xdaforums.com/showpost.php?p=18493425&postcount=1

Also, once you do that, I'd recommend doing a factory reset to ensure that anything that might have been left over in cache is wiped (unfortunately, you'll loose all of your settings, installed apps, etc by doing this but rather be safe than still broken). To wipe data, go to Settings, Privacy and tap on Factory data reset.

Good Luck!
[Acer Iconia Tab A100] 22patryk:
Thanks crossix, I'll do that. And I can always use Titanium Backup for settings and apps.
[Acer Iconia Tab A100] dms76:
You shouldn't restore settings or apps with titanium on saved game data. Restoring settings my recreate the same problems over again and you should wipe before and after you flash. The wipe before and after is probably over kill but that's the way I learned when first started flashing phone roms. Habits good or bad stick with you if that's the way you learned.
[Acer Iconia Tab A100] dms76:
Sorry can't edit a post with tapatalk. That first sentence was supposed to be only restore required saved app data.
[Acer Iconia Tab A100] ntan97:
Honeycomb apps

I noticed a lot of apps weren't kicking into the tablet optimized interface (new google docs). Was fooling around and a DPI of 130 (10 lower than what you commented in @crossix) seemed to be the what gave it that boost. Most of you probably already knew that but just thought I'd share. :)

edit: Maybe even add into your current comment to add something about honeycomb app compatibility.

#LCD Density change to 140 or 150 for smaller icons.

to

#LCD Density change to 140 or 150 for smaller icons. 130 for more tablet display apps.

but who am I to tell you to change it. Just thinking outloud.
[Acer Iconia Tab A100] eww245:
I didn't have much luck with changing the dpi, apps are ok but the HC launcher doesn't work right. Each page seems to overlap to the next, specifically to the left, so some icons are not usable.
[Acer Iconia Tab A100] ntan97:
yeah... i did have to do some rearanging, its a temporary (read:crude hack) fix for apps that are honeycomb capable but not with the seven inch... not perfect know.
[Acer Iconia Tab A100] crossix:
Thanks for the tip, I'll add it next update. I hadn't tested lcd density all the way, just becareful going too low can cause your tab to be stuck at the android logo on boot.. happened when I accidently set it for 80!

Also, if you do decide to use a lower number I'd recommend using a different launcher rather than stock due to hc launcher flaking out.
[Acer Iconia Tab A100] ntan97:
its ok... pretty much the only problem that i found is that it takes your home screens and makes them the size of the actual display, so no quick tap on left and right to switch screens because theirs no next screen to tap on, and if you do have some on the top row in 140-160 it might be up above the edge of the top screen with no way to get them down with smaller 1x(X) widgets or app shorcuts. Definitely not something to be enabled by default, but really hoping more apps give better compatibility for the 7 inch.
[Acer Iconia Tab A100] reid-o:
I'm getting checkerboarding in the browser. Is there a cause for this?
[Acer Iconia Tab A100] crossix:
It's not related to the build.prop mod, the browser works differently in honeycomb (more like it works on the iphone and ipad). Do a google search on this subject and you'll see what I mean.
[Acer Iconia Tab A100] Mystique:
using 7zip I get:

DONE!
[Acer Iconia Tab A100] Mystique:
Sorry if I was not clear..

build.prop.zip on the 1/29 post will not uncompress.

That is my problem.

If you could post the build.prop that you have that is uncompressed that would help me greatly.

Copy it to /mnt/external_sd and then uncompress it using a File Manager (I used ASTRO).

[Acer Iconia Tab A100] MikeTheSith200:
Help!!!

this mod bricked my A100!!! i have a build prop editor can you just post what needs to be changed? Or does anyone know why it bricked it? luckily i recovered it.
[Acer Iconia Tab A100] crossix:
There's a good chance you may have missed a step some where, what do you mean by "bricked"?? It obviously wasnt hard bricked since you were able to restore from a backup. So what was your tab doing after you did this mod?

The top three reasons why your tab wouldnt boot after doing this would be

a) Permissions not set correctly on build.prop file.

b) The build.prop file was not copied to the right location after you deleted the old build.prop

c) The build.prop file you downloaded was corrupt or didnt unzip correctly.

I would highly recommend if you do this mod you follow the instructions to the letter to get it to work successfully. Otherwise you'll be stuck with a tab at the bootscreen and you'll have to flash a recovery.
[Acer Iconia Tab A100] ptesmoke:
crossix just as a headsup i had to delete the wifi and interbet performance stuff in it. i just used my tab for grabbing torrents the other day. the settings caused my wifi to constantly drop. once i removed any wifi or internet tweaks it worked perfect. just a heads up tho...could just be me..
[Acer Iconia Tab A100] sephtdj:
Nice mod, thank you.
[Acer Iconia Tab A100] aznmode:
I do have it. It didnt work on HC and would just close (or maybe it was showing in 8bit mode). For sure it didn't work as advertised but trying it now on ICS with updated a500 ICS build.prop. Downloading data ATM so standby.....

EDIT: On ICS with a500 ICS buildprop change it just closes. I'm almost sure it does the same with HC so I never bothered with it. On my phone (Evo 3d) is where it played in 8 bit graphics. So thats where I got it confused.

I cant really test anymore on HC unfortunately since its a little harder to retest since I would have to donwgrade to HC, factory reset, and reinstall everything from scratch. Maybe someone else can chime in.?
[Acer Iconia Tab A100] jhsband84:
I've got the A500 build prop and just starting getting an update notification for 2.007.06 yesterday. It won't install. So I put the original A100 build prop back in and the update went away. Is there an easy edit I can do in the build prop file to make my system think it's current?

Thanks in advance.
[Acer Iconia Tab A100] Andy98:
#So I install Root Explorer and save/copy the original build.prop somehwere and change the name (ex:build.prop2) and after that download this Mod and replace it ???

[Acer Iconia Tab A100] crossix:
Its a known issue with no work around other than to switch off auto updates or install build 14 from the stock roms in the dev section.
[Acer Iconia Tab A100] crossix:
Yes

Yes (softbrick totally recoverable)

And Yes (install a stock rom from the dev section)
[Acer Iconia Tab A100] Andy98:
Thanks a lot man !! Works beautiful :D:D:D I was little scarry at beggining but now i am enjoy at maximum :D (you totally deserve 2 TYs )

Hope u guyz will release a CyanogenMod 9 :D:D for our device

Bye and all my respect for helping me to root and modd my tablet ;)
[Acer Iconia Tab A100] belber095:
Will you be making a modified build.prop for ics anytime soon?
[Acer Iconia Tab A100] crossix:
Yes, I'm working on putting together one as I type this :)
[Acer Iconia Tab A100] belber095:
sweet (:

i know that devs don't really appreciate this, but since it's not a ROM, and we don't have a custom recovery, do you have an ETA on that?
[Acer Iconia Tab A100] crossix:
Nope sorry, I dont give ETAs and its very rude to ask for such at all anywhere on XDA reguardless if its a ROM or otherwise.

Before I release something of this nature I thouroughly kick its wheels and try to think up ways to break the thing Im going to be releasing. I want to make sure what I add is actually going to serve a purpose and actually does the thing its supposed to do. I also research new things to put into a build.prop spending countless hours scouring the net and documentation for different settings.

With all of that, I also have other things I work on and do in my spare time like hold down a 40hr+ work week and with what little time I have left over, I like to spend it with my daughter before she has to go to bed.

Now what was that about an ETA? Oh nevermind..
[Acer Iconia Tab A100] belber095:
a simple no would have been fine too. i'm not arguing anything against that. i'm sure everyone here appreciates everything you're doing, including myself.
