[Fairphone 1] paphko:
I am using this phone for about 10 days now (comparing it to my Galaxy S3) and I would like to share my experience.

1. hardware

The hardware is sufficient for using it as a daily driver for calling, messaging, surfing the web, etc. I didn't test games though.

Some more details:

- good built quality but quite heavy.

- The screen is ok, a little bit too bright in dark rooms. Using Xposed framework with Gravitybox, the lower bound can be set a bit lower though.

- The touchscreen is not as sensitive as the Galaxy S3 screen, but still usable. Sometimes you just need to touch a bit 'stronger'. But I like the smaller size of the phone (4.3")!

- Mic and front speaker quality is good.

- The back speaker is incredibly loud. The lowest option is still too loud to listen to music in a quiet room. I didn't try to turn it louder than half way - it is really loud and the quality is just too bad. I use an equalizer of my music app to turn the volume further down. Then it is ok.

- The camera is just ok. Definitely worse than the camera of the S3 but good enough for quick shots.

- The dual SIM option is really good, in contrast to most other recent smartphones, regular (not micro) sim cards are required.

- Micro SD card is an option I don't want to miss.

- GPS does not work that well, maybe because GLONASS is not supported. Navigation was several meters off, see screenshot. For me it is not usable for navigation.

- The battery is average, 1.5 days with average usage. However, the remaining capacity is apparently not reported correctly. It often sticks at 14% for several hours of use. Then after a while it decreases normally again.

- 1gb ram... could be more, but probably sufficient for an average user

- 1gb for apps is ridiculous for a device with 16gb internal memory! Re-partitioning should solve this issue though.

2. software

- The software is very close to stock Android 4.2.2, just the launcher and some additional widgets (Peace of Mind, Google Apps Installer, Your apps) are added. The 'Your apps' widget seems to be some recent-apps launcher which is only working with the Fair-OS Launcher, because it does not work with Nova Launcher.

- Pre-installed apps include a tasks and a notes app, a simple file manager, a backup and restore app, an OS update checker, and a fm radio app

- The Dual-SIM functionality is really nice which I think is built into Android (I might be wrong, it's the first dual SIM phone that I'm using). The options 'sim 1', 'sim 2', 'always ask' are available for 'void call', 'video call', and 'sms/mms', whereas 'sim 1', 'sim 2', and 'off' are available for 'data'. Furthermore, each contact may be assigned to one specific sim card. Very well implemented.

- There is already a superuser app pre-installed! :)

The rest does not differ much from stock Android.

3. With the following configuration it is not even necessary for me to look for a custom Rom like Cyanogenmod. There are all the features I need :)

- Xposed framework with two modules:

- Gravity box for a lot of customizations like statusbar transparency, hiding battery and alarm icons, extended reboot menu, screen brightness adjustment, torch in lockscreen, etc.

- App settings to revoke app permissions

- Nova launcher, much more functional than the Fair OS launcher

- Music app with equalizer to reduce volume

- Focal camera app to get some more options for taking pictures
