If you are a keyboard afficionado, you may have heard about the F(x)tec Pro1 and Pro1-X phones with integrated keyboards. Together with some peers of the LineageOS team, I have ported LineageOS over to the Pro1-X. It is still early stages, but eventually, LineageOS will be available as a shipping option for the phone!
Head over to my XDA thread, Github or the LineageOS Gerrit review if you would like to check out progress and/or help out.
Some more good news for the end of 2022: LineageOS 20 has just been released. And I have had a hand at it, as the main maintainer for:
Sadly, of course, the Sony devices will not be updated beyond Lineage 18.1, but still! You may now enjoy a whole slew of improvements if you own a OnePlus 5/5T: better GPS locking, improved audio quality, faster UI performance just to name a few.
We poured a lot of hard work and blood, sweat and tears into this, so please do enjoy. This is also a great opportunity to thank all the people who donated equipment for this effort, please have a look at the hall of fame!
There are some exciting things coming up, so keep watching… and have a happy new year everyone!
After software support for OnePlus 5T ran out 2 years ago, we spent a LOT of time getting OnePlus 5 and 5T up to speed on LineageOS. By now it is safe to say that LineageOS on these devices is superior to OxygenOS, especially in terms of performance and battery usage. We ported over EAS (energy aware scheduling), fixed tons of big and small errors so now everything is working smoothly. The latest official version is based on Android 12, but the version for Android 13 is in an even better state already, so it will be released rather soon!
Also, some legacy devices got some much needed love, such as Sony Xperia Tablet Z2 WiFi and LTE variants. Both of them are now running LineageOS 18.1 based on Android 11 just fine.
Go check it all out at the LineageOS Download Center.
I would like to take this opportunity to thank all the donors who donated money and in some cases even devices for me to help improve the situation. Your help is very much appreciated, and you guys are all in the Hall of Fame!
There seems to be a lot of confusion amongst developers how to get persistible permissions when using the SAF. Wasted some hours on this, so it is worth a note here.
To get the average file open dialog using the SAF, one could do this:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
startActivityForResult(i, 0);That works perfectly fine, but after a reboot, the permissions are gone, and opening the same file (without opening the dialog again) will fail. There are lots of resources on the Internet that tell developers to add some arguments when calling the Intent. This is wrong! Passing these to the intent is completely useless:
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // Don't do this
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION); // Also no!
intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION); // NO!Instead, a single call to takePersistableUriPermission will retain permissions even after a reboot:
protected void onPropertyRequestResult(int propertyRequestCode, int resultCode, Intent data) {
getContentResolver().takePersistableUriPermission(data.getData(), Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
}Today, I am happy to announce the start of CyanogenMod 13 nightlies for Xperia Tablet Z (pollux) and Xperia Tablet Z Wifi (pollux_windy). This means CM13 is considered stable enough for daily use on these devices, so the terrors should be rather limited. Anyone interested can find the official downloads at the usual location. Active development on the fusion3 platform is ongoing, I will attempt to shift focus to the phones now.
Today, Xperia Tablet Z booted into CyanogenMod 13 for the first time. Many things still broken, but it is a start!
As of today, all Sony Xperia devices based on the Fusion3 board (Xperia Z, ZL, ZR, Tablet Z, Tablet Z WiFi) are getting official CyanogenMod 12.1! When I first started looking at these devices in December 2014, the CM12 source code would not even compile, let alone boot, and even the recovery was broken.
Well, here we are, hundreds of commits and quite a lot of annoyances later: F2FS is now supported, a plethora of kernel changes and the new BFQ scheduler made the user experience better than ever, the latest proprietary blobs are integrated, SELinux is properly set up, and a ton of reorganization and cleanup has been done – for all of Sony’s MSM8960 devices and beyond.
Still many things to do, but for today, I’m lighting a cigar! If you have one of these devices, check out GET.CM and give it a whirl. There is a truly fantastic team of developers at Cyanogen and CyanogenMod, and without them, none of us could enjoy mobile computing quite like we do.
After a long, arduous development road, I’ve enabled CyanogenMod nightly builds for the Sony Xperia Z. This brings nightlies directly from CM11 to CM12.1, which hopefully all users will enjoy. Thanks to everyone at my XDA thread, especially Andy van der Steen, who lent me his phone for development. Without that, I would never have come this far.
Starting with early March 2015, CyanogenMod for the whole original line of Sony’s Xperia Z devices support F2FS, a filesystem optimized for flash memory. Tests have shown it to outperform the default ext2/3/4 that we used previously, so definitely a nice thing to have.
However, if you want to benefit from F2FS, you need to manually convert your phone. Be aware that this needs some understanding of how to use ADB and the conversion process will DELETE all you user data/settings!
First, you need to have CyanogenMod 12 or higher installed on your phone, and be using the official recovery. Also, you need ADB installed and ready to use on your computer.
This is how you convert to F2FS:
– Connect your phone via USB and boot into recovery mode
– Open a command line and type “adb shell”
– Type “mkfs.f2fs /dev/block/platform/msm_sdcc.1/by-name/cache”
– Type “mkfs.f2fs /dev/block/platform/msm_sdcc.1/by-name/userdata”
– Reboot the device
After a long development phase, Xperia Tablet Z and Xperia Tablet Z Wifi are now on the official nightlies list of CyanogenMod 12.1, not least thanks to testers on XDA and generous donations.
The list of improvements since CM12 is immense, with a load of kernel updates that makes these devices as smooth and fast as they have never been on CyanogenMod.
Enjoy people!
