Updates

Hey guys just wanted to give you all an update. I got CM12 to boot! I have reworked the posts in this thread to make room. Once again this work is brought to you by the work of [MENTION=3044346]arco68[/MENTION] [MENTION=5292938]DevConnection_Team[/MENTION] and [MENTION=4825437]Christopher83[/MENTION] , and probably others.

Please also keep in mind this build and all future builds are OS2SD so follow those install instructions. And make sure you backup data!

Also remember not only are alot of Cyanogenmod features still missing but this rom in general is still in very early alpha stages. The list of non-working is just what i found in a hour or so of use.

[MENTION=4110627]cars1198[/MENTION]Sweet! My new batteries should be here 2morow! I hope so, can't wait to make the switch! NICE WORK & THANK YOU! You da man!
[Samsung Galaxy Exhibit 4G] cars1189:
New version labeled with v2 has 2 items on the non-working list fixed! If anyone happened to have picked up the first build. Still might have more unknown issues let me know!
[Samsung Galaxy Exhibit 4G] canodroid15:
1st boot

[MENTION=1816400]cars1189[/MENTION] OK my batteries came in! I just made the switch & installed CM 12 all seems good just waiting on the 1st boot as I type! I'll update soon! Thanks again bro!

Well its been 20 mins & still no boot just spinning CM animation. I'll wait a few more mins & pull the battey. I'm not to worried, this happens on my S3 as well with cm12

OK got past the boot ani. Its optimizing apps! Fingers crossed
[Samsung Galaxy Exhibit 4G] canodroid15:
[MENTION=1816400]cars1189[/MENTION], OK got it up & running so far so good, can't wait to OC its kinda slow & lags a bit at times. Installed Seeder apk & it helps a lot. Oh & I flashed PA Gapps full modular package too & still got space to spare! Great job man I can't wait to see what this becomes! 3rd party camera apps work with no issues here!
[Samsung Galaxy Exhibit 4G] danny8:
Just bumping this thread to let y'all know I'm still following this phone's development. Looking to update my Exhibit from SlimROM some day soon, maybe after seeing how this ROM shakes out.

Thanks for keepin' on!
[Samsung Galaxy Exhibit 4G] canodroid15:
So far its running like a champ! Torch is broke again & the stock camera is buggy as cars mentioned ,WiFi works, haven't tested Bluetooth yet all in all its easily a daily driver in my opinion! Another unbelievably awesome job by cars1198 & thanks to the guys over at the galaxy W thread!!!???
[Samsung Galaxy Exhibit 4G] cars1189:
Yes the torch app still needs to be changed to the modified version. And probably a few other kinda small things this is only like 1 of 2 builds i got booting so i havnt gotten to all the other stuff yet.

And yes if you guys would please show your support over in the other guys' thread that i mentioned before. Show em some love too. We wouldnt be here without them.
[Samsung Galaxy Exhibit 4G] canodroid15:
Just a few screenshots for those curious!
[Samsung Galaxy Exhibit 4G] canodroid15:
Update! After a good 30 some hours & letting things settle in, this build is running nice & smooth! All the lag has settled out & every thing is working great, WiFi, bluetooth ect.. The only thing I'm unable to test is cell service & data, & the camera is working fine now!
[Samsung Galaxy Exhibit 4G] theking1st:
It has been working great for me so far. Everything seems to be working very well so far. Calls, messages, data, WiFi, everything is working well. It was a bit buggy at the beginning but it has settled down with time. It is sometimes slow and a bit buggy but I can live with it. Just waiting for the OC kernel and some updates to add the CM ROM features like screenshot and stuff. The battery life is way better than on the CM11 ROMs.

Anyways, thanks to all the developers, and mostly to [MENTION=1816400]cars1189[/MENTION] for the amazing work that has been done on this device.

It was around 3am that I woke up and I decided to come on the thread to see if there were any update and I found out that there was a CM12 update up and I went ahead and flashed it right away even while I was still sleepy. When it booted up I thought I was dreaming cause I was still sleepy! LOL.

Thanks for the amazing work guys! You are AWESOME!

PS: More updates coming up
[Samsung Galaxy Exhibit 4G] cars1189:
Hey guys was just wondering is anyone else having issues with sending texts while wifi is off? I can get texts with wifi on or off but i cant send with it off/disconnected.

Also side note i did kinda ninja a build uploaded (1-14-15) not alot changed though i dont think which is why i didnt mention it. Im probably gonna make several builds while working stuff out so i dont wana spam the thread with "new update" posts.

Edit: I think i have found a solution but just want to get confirmation that it is a bug and not just my service/reception or something. Most likely ill have it worked into next build or a zip soon since its a pretty major bug..

Edit: It seems to be a in and out situation. Call and Text is unreliable.
[Samsung Galaxy Exhibit 4G] theking1st:
I have "not encounter" this problem since I flashed the ROM but last Saturday I had 2 SMS that haven't been sent even though I was connected to my house WiFi. And on Sunday morning I sent a long text that didn't go through when I checked later that day. I wasn't connected to any Wi-Fi at that time, so I don't know now why it happened. But all these happened at a moment that the phone was slow. You know, sometimes for whatever reasons the phone starts slowing down and apps start to crash and it take minutes to open just the messaging app. So it might have been this.
[Samsung Galaxy Exhibit 4G] canodroid15:
Does anyone experience heavy lag in os2sd twrp? Whenever I click on something it hangs until I touch the screen again, haven't tried cwm yet as I'd rather stick with twrp. Just wondering? Anyways everything else is GREAT!
[Samsung Galaxy Exhibit 4G] aaopt:
Yes, I have this problem too. Not sure but it seemed like disabling MTP (under Mounts) helps somewhat. But MTP is so useful, and on subsequent boots after I changed the setting MTP remained off but it was still laggy. Maybe it just needs more time to settle upon boot for some reason?
[Samsung Galaxy Exhibit 4G] canodroid15:
[MENTION=3729448]aaopt[/MENTION], I believe once we get a good working OC kernel, a lot of the out of the blue heavy lag will dissolve itself in the OS & hopefully in recovery as well. It seems like the only time I experience heavy lag in the OS is when a lot of resources are being used like sync, & app updates. If I wait until those ate finished every thing runs smooth
[Samsung Galaxy Exhibit 4G] aaopt:
Could be. But I have never used an OC kernel, and I've also never seen lag like this in TWRP before.
[Samsung Galaxy Exhibit 4G] cars1189:
Hey guys thanks for the feedback. The issues with twrp are ones i get too. I never used it before and only just recently started using/building it based off jfbs last source before he left. Whether or not the settings he had where correct or experimental or not im not sure. I tested the build and it worked well enough so thats what i used. Ill look into it and see if i can work it out. As far as OC kernels go im not 100% sure if im going to release any yet as im still trying to test for/watch for bugs and tweaking is not good for this time. Eventually ill get to it just like i did before.

About the not sent sms i had that and then the next day i also had issues with calls and texts not sure exactly why. At this time though i would recommend most users stick with cm11, it may or maynot just be issues in cm12.
[Samsung Galaxy Exhibit 4G] aaopt:
jfbs' TWRP builds did not have these lag issues. Since your settings are based on his, perhaps the lag might be a 2.8-vs-2.7 issue. There have been some updates after 2.8.1 so there is a chance that a fresh build might work better.
[Samsung Galaxy Exhibit 4G] canodroid15:
Yeah I'm on 2.8.4.0 on my old s3 I think an updated build could help but who knows what's really causing it. I switched to cwm & it works great, I do like TWRP better tho, I'll stick with cwm for now till [MENTION=1816400]cars1189[/MENTION] figures it out
[Samsung Galaxy Exhibit 4G] cars1189:
Ill release a new build with next rom release. See what happens.
[Samsung Galaxy Exhibit 4G] theking1st:
Okay! Thanks for your work man!

Fix for Gestures Keyboard bug

I'm really enjoying CM12 on the Exhibit -- thanks for all the work cars1189 and everyone else, its great having Lollipop on this phone. One issue I had was that gesture / swipe didn't work with the keyboard. This is a known CM12 bug with an easy fix: http://forum.cyanogenmod.org/topic/103962-no-gesture-typing-in-aosp-keyboard/ -- basically download a file and put it in /system/lib/
[Samsung Galaxy Exhibit 4G] aaopt:
Wouldn't it be easier to just install Google Keyboard from the Play Store? Not certain but it sort of smells like the suggested fix in that thread might be just replacing the aosp keyboard with one file from the Google build.
[Samsung Galaxy Exhibit 4G] swicago:
First...thank you very much for this awesome upgrade cars1189, you rock ...

Now question is ROM 1-11-15v2(OS2SD) or ROM 1-14-15(OS2SD) the latest build?

I assumed the latter, because of the date, but the prior is a tiny bit bigger and the majority of the comments are for it.

I just installed ROM 1-14-15 and it booted fine. Now it is Optimizing the GAPPS

Again Thanks for bringing new life to my old azz phone.
[Samsung Galaxy Exhibit 4G] cars1189:
Yes 1-14-15(OS2SD) is the newest. CM12 is still changing alot and as it changes the file size is going to change a good bit up and down. For example they just added 2 cyanogenmod apps so next build will probably be noticeably bigger. And as they change those apps maybe for 5.0 they might remove some things or add some things changing the size again. Also sometimes when they add i remove, for example with cm11 i removed cm updater because it doesnt do anything for us anyways and we where low on space. Anyways...90% of the time the one with the newest date will be the best to use. (always the newest not always the best but a good place to start for trying it new from another rom/fresh install)
[Samsung Galaxy Exhibit 4G] swicago:
I can report that this ROM is awesome. Got everything I need working, including openvpn. It was super slow at first, but that was do to a restore(7k+ sms) to the message app. It was building all the conversations. But after that first evening it was smooth sailing. AGain, thanks for the awesome work on this.
[Samsung Galaxy Exhibit 4G] ScoobSTi:
Glad to see this phone is still getting some love! I have a different phone now, but I still have 2 of these Exhibits just sitting in my drawer. I might just flash these on there and use them again, probably as music player.
[Samsung Galaxy Exhibit 4G] cars1189:
Well it appears the sms issue isnt solved and im having issues trying to narrow it down. Unfortunately the ril is still stock proprietary lib and my success on opensourceing it hasnt gone well i have tried using the opensource samsung ril used for other devices however, i simply dont know c/c++ that well and the errors compileing im getting i dont understand. I know enough to modify and tweak some like i have done for a few things in the past but thats about it. Although since sms works fine when wifi isnt in use from time of boot i suspect it to be more wifi related. Which all but the firmware i think is opensource but i havnt been able to find the issue in logs. If anyone has this issue maybe more logs might help.

At first i thought it might be ril related but since ive narrowed it down to being when wifi gets turned off/disconnected after being on, that is why i think its more wifi. Although it might still be ril related and maybe something to do with wificalling in our ril somewhere im not even sure if thats possible but as our "sister devices" dont share the same issue despite shareing the same wifi code im really just completely confused really and since im the only one working on this device and our "sister deives" devs are pretty busy otherwise/havnt gotten any responce from them im not sure i can fix this im going to continue working though. However for now id recommend leaveing wifi off while you will still be able to get sms sending doesnt seem to work till you reboot.

Tagging every dev i know so maybe they see this and might be able to help because im at a loss. [MENTION=3044346]arco68[/MENTION] [MENTION=4825437]Christopher83[/MENTION] [MENTION=4833280]Madridii[/MENTION] [MENTION=4764217]davidteri91[/MENTION] [MENTION=5292938]DevConnection_Team[/MENTION]
[Samsung Galaxy Exhibit 4G] swicago:
This happened for the first time to me today. But I did not have wifi (client mode) on, but rather tethering (AP mode) on. I didn't think anything of it and just rebooted.

I may be able to reproduce it, but do not know where the logs are.

Let me know if I can help in some way.
[Samsung Galaxy Exhibit 4G] theking1st:
I reinstalled mine but with CWM this time and I don't have this bug. Wi-Fi on or off, I still send and receive SMS without any trouble.
[Samsung Galaxy Exhibit 4G] exhibit679:
Might be easier. I'm not really sure on the difference between the AOSP and the Google keyboards. But I like saving the disk space by not having 2 keyboards if I'm happy with just the AOSP one (when it has swipe). But mainly I posted in case anyone else (besides me) got confused as the keyboard seemed to support swipe (showed trail, etc) but always returned just one letter.
[Samsung Galaxy Exhibit 4G] cars1189:
While im uncertain how this could work, id like to note that untill you have extensively tested this everyone should proceed with caution. I too have been able to send sms, the issue isnt 100% repeatable consistently. Sometimes i reboot and toggle wifi and it works other times it doesnt. Which is why at first i was unsure if it was a service issue or software which is why i have been adking about it. Recently [MENTION=4825437]Christopher83[/MENTION] made an update to our java ril for multipart sms which we are discusing now. In which sparks my questioning is it multipart sms that you guys are sending that is failing? For me when it stops working even sending a sms with "1" it doesnt work, so i believe our issue is different, but some feedback would be nice.
[Samsung Galaxy Exhibit 4G] cars1189:
New Build is up.

Edit: Also if you guys havnt noticed i have started uploading the md5 file for checking the files for corruption. If you add the md5 and rom zip in the same folder twrp will check it for you before flashing.
[Samsung Galaxy Exhibit 4G] jibinj:
Nice Work

[MENTION=1816400]cars1189[/MENTION] Awesome. Thanks for your work.

Here is the issues I'm facing

1. Android is Upgrading message every time restarts.

2. Little bit slow(hope it will be fixed when OC is available)

3. First setup is too slow.

Again Thanks for your good work. :):)

2-1-15 Experience

I just dirty flashed from 1-14-15 to 2-1-15. (Any reason I'd need to do a wipe?)

The Good:

The 1-14-15 ROM seemed to have had some display glitches with notifications. Swiping down to see notifications would show a stale notification, but doing it again would sometimes get the current notification. So far I haven't had any issues. We'll see when I change the dpi from 240 -> 182 as I'm not convinced that was unrelated.

Newer CM12 has more customization under Personalization.

I'm sure stuff I've missed as I just flashed it.

The bad:

The ROM feels slower. The 1-14-15 felt much faster than CM11 which I attributed to ART. This definitely feels slower than 1-14-15 though and maybe even the CM11.

The whatever:

Installing new packages and upgrades is very slow. This is an underpowered phone compiling ART, what do you expect. Maybe it is slower than the 1-14-15 ROM, but maybe I just did upgrades on bigger software.

On startup it seems to take the phone a long time to find its cellphone data connection. Shows an empty triangle for a while, but it eventually finds it.

Also I can confirm what [MENTION=5820924]jibinj[/MENTION] reported: after every rebootI get "Android is upgrading (1/1)" on startup.

Thanks for all the great work [MENTION=1816400]cars1189[/MENTION]. It is amazing what this little 3 and half year-old phone can do thanks to your work.
[Samsung Galaxy Exhibit 4G] cars1189:
So to start i think its about as fast as its gonna get for the most part. OC kernels will come soon i think the only few bugs left are getting worked out so i feel kernel tweaks can start soon. The slow start/first boot is slow i think 99% just because of art which is why i dont think its going to get much faster. The slowness might be at least partly attributed to the force high graphics in the build.prop you can change it to false and test. I adopted it because i thought it might work but the other phone our "sister devices" have a faster stock cpu and i think therefore can handle it better. The cell connection startup i think is faster than the first build but its still not great not sure if this can be changed it might be because of outdated proprietary ril stuff which might openource eventually and git better but i wouldnt hold your breath. The android 1/1 upgrading or w.e. i only have seen so far when changeing /system things like changing build.prop things updating or installing system apps. If you get it repeadedly without changes maybe try doing a fresh install.
[Samsung Galaxy Exhibit 4G] exhibit679:
Having used this build more, it definitely is much slower than the Jan 15th. I'm getting browser and other apps fake crashing: 'this application is not responding: Wait / Close'. (And one hard crash where phone rebooted). I think that with the slowness, applications are hitting timeouts (unless it is a memory leak or something).

I went into to Settings,performance, and turned off force high graphics mode. Is there anything else I need to change? I didn't notice a difference when I did that (and rebooted). It would be great if we could get the speed of the Jan 15th build back. I'll probably flash back for the speed ( and confirm it isn't all in my head, but task switching, open apps, scrolling, button selection all feel slower). All the other issues of this build are minor. (And the android is updating on startup just went away, maybe it just takes a much of boots / builds).

Cheers.
[Samsung Galaxy Exhibit 4G] canodroid15:
Im pretty sure it'll get better with the OC kernel, until then, not much you can do about the speed. I use "disable services" app & only run the apps I really need & it runs pretty dang good for me. I always clean flash too, used to dirty flash but gave that up long ago on this phone as it caused too many issues
[Samsung Galaxy Exhibit 4G] exhibit679:
I got my stale notifications bug (anyone else see this?) on the 2-1 build, so I did a fresh install of the 1-14. Feels much faster (usage and boots). So far, notifications are fine. I'll do updates / installs slowly to see what (if anything) breaks notifications. Anyone else find 2-1 build slower than 1-14? Maybe my dirty flash caused some problems and I should do a clean install of the 2-1.
[Samsung Galaxy Exhibit 4G] exhibit679:
Notifications Issues

I think my notifications issues (stale notification, swipe down, swipe up, swipe down, see different newer notification, but only one) started when I upgrade Google Play Services. Everything was fine until I did that upgrade (and updated a few apps that required new Google Play Services like Hangouts). Anyone else seeing this?

I started with the 11-09-14 Gapps. I believe this timing is consistent for both 1-14 and 2-1 builds, although I wasn't paying super close attention with the 2-1 build.

I'll probably try downgrading and seeing if that fixes things.
[Samsung Galaxy Exhibit 4G] Kotetsukun:
I found the new oc kernels for the latest cm12 build (2-1-15)here

Anyways downloaded the new recovery, rom and kernels and I will flash it on my friend's exhibit I am borrowing. There's not much since she factory reset in case she wants to lend it to me, so I'll just wipe data cache system dalvik and internal storage and partition my new 32gb sd card I bought to ext4 this thing. Then flash recovery then flash the rom inside that recovery then flash gapps and tada you got lollipop!
[Samsung Galaxy Exhibit 4G] shelium:
I got one of these over the weekend and decided to take this ROM out for a spin. Unfortunately it was to slow to be used as a daily driver. After I've gone ahead and flashed the OC Kernel though I can say the speed had dramatically improved though it could be better. The one thing that I can't figure out is why I lost WiFi. I'm not certain if anyone has that issue and if there's a fix for it. I'm still reading through the thread. Nevertheless... Thanks for the hard work Devs!

[Edit] So like I was reading it's a K^Kernel issue. I flashed ADC and the WiFi is back. I haven't seen a fix for it though. Does a clean install with the K^Kernel fix the issue? Also, what do you think the best partition table for a 16GB card is?[/EDIT]
[Samsung Galaxy Exhibit 4G] cars1189:
The OC kernels dont work which is why i haven't posted them... The issues i saw with K^Kernel is wifi broken and sensors(accelerometer and compass) broken. IF you guys could test these three things and report back what is and isnt working for the builds you have tested that would help a bunch. wifi is pretty easy to test but for sensors... sensor box on the play store works nicely.

Currently OS2SD doesnt use external sd for anything but external storage. So you are kind of limited but you could split it and add a partition for swap or something and manually set it up with an init script or something. And the first partition(external storage) is mouted with "auto" so it can be ext4 exfat f2fs w.e. you want should work fine.
[Samsung Galaxy Exhibit 4G] canodroid15:
[MENTION=1816400]cars1189[/MENTION] I'll test all 3 shortly & report back, off you want me to I'll log out the errors & send them to you, just let me know, I'm on the latest build & have all 3 k^k kernels, and the ADC kernel downloaded. Thanks bro!
[Samsung Galaxy Exhibit 4G] cars1189:
Yes locgats and dmesg logs would be great. You can use pastebin or w.e. to send em.
[Samsung Galaxy Exhibit 4G] Kotetsukun:
[MENTION=1816400]cars1189[/MENTION] So far so good. Playing with the new lollipop build. It does feel awesomely speedy, if it wasn't for gapps.

The bad thing is... People who are saying that it is slower is because of the gapps. The installation time of apps are very very long, like the time I am installing those gapps. Yep it took almost one hour to finish its first boot! So I flashed it cleanly without the gapps and it worked fine. No Google apps though, so no YouTube. I will find a way to watch YouTube videos such as UC browser and TubeMate.

So far right now, It's performance is wonderful with some very minor flaws.

Wiped system, data, cache

Flashed 2-1-15 build

Flashed ADC linaro kernel

Flashed supersu

Reboot

No gapps

Installed aptoide, mx player, etc.

btw, Tried all the k kernels and no wifi, no accelerometer, and no compass. Plus one of them cause a hard crash in performance settings, which is why I went for the ADC.

HOPE YOU GUYS EXPERIENCE IT.
