[Galaxy S3 Neo Android Development] prototype74:
F.A.Q

Q: How to root it?

A: Grab Magisk from here.

Q: Does Wi-Fi, Bluetooth, Camera, (dual) SIM, GPS, NFC etc. work?

A: This is a common question but asked very often. Yes everything works execpt those which are mentioned in Known bugs and issues section.

Q: My phone stucks at splash screen.

A: This means you don't have latest KitKat Bootloader & Modem installed as mentioned in installation instructions or the installation was not successful.

Q: My phone bootloops!

A: You probably selected the wrong camera sensor. Reflash the ROM without wipes and select the correct camera sensor. For all other cases make sure you followed the instructions carefully.

Q: ROM booted but there are some apps missing. Why you removed these apps?

A: I didn't, YOU removed them in aroma installer. Reflash the ROM again without wiping data and this time don't remove them.

Q: My signal constantly disconnects and shows "No Service" in statusbar or my SIM isn't working at all.

A: We're using the latest Marshmallow MSM8626 GSM RIL blobs, so make sure your baseband is up-to-date too, if that's the case then probably your provider doesn't support all network bands. So check if your provider supports 3G and 2G networks in order to have a stable connection.

Note: Some providers shutdown 3G network to focus to newer 4G/5G network technologies. It might be possible that your provider did shutdown most or all 3G and/or 2G networks.

Q: What's the difference between (n_)s3ve3g, (n_)s3ve3gxx, s3ve3gjv, s3ve3gds and s3ve3gdd in about phone?

A: The differences in kernel name or build number represents as following:

In Kernel name:

- n_s3ve3g: Samsung camera with NFC

- s3ve3g: Samsung camera without NFC

- n_s3ve3gxx: Sony camera with NFC

- s3ve3gxx: Sony camera without NFC

In build number:

- s3ve3g: GT-I9301I (Samsung camera)

- s3ve3gxx: GT-I9301I (Sony camera)

- s3ve3gjv: GT-I9301Q

- s3ve3gds: GT-I9300I

- s3ve3gdd: GT-I9300I (without NFC)

Q: Does SafetyNet pass?

A: Yes, it does. Rooting or other heavy ROM modifications may cause SafetyNet to fail, so be aware of it.

Q: Can I use NFC for mobile payments?

A: Unfortunately no, our NFC chip doesn't support HCE (Host Card Emulation) which is required for mobile payments with NFC. Only Android Beam is supported.

Q: There is no NFC option!

A: As a reminder, s3ve3gdd (I9300I SWA variant) does not support NFC, if you own one then you won't be able to use it, if not check these:

- Check if your baseband/bootloader does not start with "I9300IDD"

- Kernel version naming ends with "n_s3ve3g" or "n_s3ve3gxx"

- Make sure your battery has a NFC chip (from NXP pn547) included which is meant for S3 Neo (it's usually printed as "Near Field Communication")

Only if all cases above are present, you will see NFC option and an icon in statusbar if enabled

Q: My phone's CPU doesn't enter deep sleep. Is that a bug?

A1: Seems so but from Samsung side. Just peform a normal reboot but not while connected to any charger/usb cable.

A2: This bug has been fixed in v2.0+. If your CPU can't enter deep sleep anyway, then it's most likely caused by an app.

Q: Can I flash a camera fix from other ROMs to fix camera (sony)?

A1: If it would fix it, don't you think I would have it implemented in this ROM already? No, camera fixes from other ROMs will not fix the camera and it's highly recommended NOT to flash them in this ROM!

A2: This bug has been fixed in v2.0+

Q: My GPS does not find my location. Any fix?

A: Download GPS Test app from Google play, run it, go outside and wait 10 minutes to get your fix :D

Q: How about random reboots?

A: This ROM is guaranteedly

not

affected by random reboots 💪

Q: Do I have to clean flash when there is a new update?

A: Nope.

Q: There is no CSC folder in /system. How to add CSC features?

A: This ROM is featured with OMC, a new multi CSC solution. Locate to /system/omc and add your features to seperience.xml (custom csc).

Q: I've selected screen recorder in aroma but I can't find it in settings. How to use screen recorder?

A: You can find it's settings in settings > advanced features > screen recorder. To start recording, pull down quick settings, search for Screen Capture tile, extend it and select screen recorder.

Q: XYZ app does not work/force closes and I want create a log to help you. How can I create a logcat?

A: I'm glad you'd like to help. Follow this xda tutorial or download any logcat app from Google Play.

Q: Will there be a nougat Samsung experience port?

A: It was planned. More info here.
