Replicant 4.2 0003 on I9300

The Replicant project released version 4.2 0003 recently. I have been using Replicant on a Samsung SIII (I9300) for around 14 months now. Since I have blogged about issues with NFC and Wifi earlier, I wanted to give a status update after upgrading to 0003. I’m happy to report that my NFC issue has been resolved in 0003 (the way I suggested; reverting the patch). My issues with Wifi has been improved in 0003, with my merge request being accepted. What follows below is a standalone explanation of what works and what doesn’t, as a superset of similar things discussed in my earlier blog posts.

What works out of the box: Audio, Telephony, SMS, Data (GSM/3G), Back Camera, NFC. 2D Graphics is somewhat slow compared to stock ROM, but I’m using it daily and can live with that so it isn’t too onerus. Stability is fine, similar to other Android device I’m used to. Video playback does not work (due to non-free media decoders?), which is not a serious problem for me but still likely the biggest outstanding issue except for freedom concerns. 3D graphics apparently doesn’t work, and I believe it is what prevents Firefox from working properly (it crashes). I’m having one annoying but strange problem with telephony: when calling one person I get scrambled audio around 75% of the time. I can still hear what the other person is saying, but can barely make anything out of it. This only happens over 3G, so my workaround when calling that person is to switch to 2G before and switch back after. I talk with plenty other people, and have never had this problem with anyone else, and it has never happened when she talks with anyone else but me. If anyone has suggestion on how to debug this, I’m all ears.

Important apps to get through daily life for me includes K9Mail (email), DAVDroid (for ownCloud CalDav/CardDAV), CalDav Sync Adapter (for Google Calendars), Conversations (XMPP/Jabber chat), FDroid (for apps), ownCloud (auto-uploading my photos), SMS Backup+, Xabber (different XMPP/Jabber accounts), Yubico Authenticator, MuPDF and oandbackup. A couple of other apps I find useful are AdAway (remove web ads), AndStatus, Calendar Widget, NewsBlur and ownCloud News Reader (RSS readers), Tinfoil for Facebook, Twidere (I find its UI somewhat nicer than AndStatus’s), and c:geo.

A number of things requires non-free components. As I discussed in my initial writeup from when I started using Replicant I don’t like this, but I’m accepting it temporarily. The list of issues that can be fixed by adding non-free components include the front camera, Bluetooth, GPS, and Wifi. After flashing the Replicant ROM image that I built (using the fine build instructions), I’m using the following script to add the missing non-free files from Cyanogenmod.

I hope this helps others switch to a better phone environment!

  2. hi simon,
    thanks for your great work!
    do you know how to get gps to work on a galaxy s2?
    i’m trying to get it to work on my s2 with replicant and saw a post of a user “dllud”, referring to your blog. he apparently modified your instructions for a s2 (see below).
    unfortunately, just copying the two files doesn’t seem to work. i can’t find any file “gpsd”, neither in nor on my phone.
    do you know anything about this?
    any help would be greatly appreciated! 🙂

    Why don’t you also add the proprietary GPS drivers? The files for the i9100 are:
    /system/lib/hw/ /system/lib/hw/
    /system/lib/ /system/lib/
    (from ) “

  3. Hi

    I installed Replicant on S3 and it works great. I was wondering if removing the
    blobs is equally easy to do. Will it be the same commands as described, only
    changed to a deletion command? Or does installing the blobs have some side
    effects that will remain on the device?

    While you are at it, is there any blobs to try that deal with the touch screen?
    It is maybe a little slow in the response, although still OK as you say.

    • I believe removing the blobs is just as easy as removing the files. Having the files present should not cause any side effects. The software will load the firmware if present, and skip it if otherwise.

      The touch screen is a bit slow due to missing EGL implementation. This is not a firmware issue, so cannot easily be worked around. Unfortunately…
