Same here :(

Great ROM, it's my daily ROM since a long time.

After several days of daily use this is my report of use about this RR Stable 18:

Characteristics:

No Bluetooth loss of signal!

Good camera quality.

Full Substratum support.

Very stable (isolated FC seems corrected with Kernel Adiutor fix).

Very fluid, until the end of the day.

Lots of configuration options (it's an RR)

Android 7.1.2 NJH47F Compilation of August 2017.

Kernel based on version 3.10.108 of November 2017.

December Google Security Patch (r36) , safe from Blueborne and Krak

Z-RAM, can be especially useful on 2 GByte RAM model. Can be activated with applications such as Kernel Adiutor (the one I use) and others that allow to activate kernel options.

SDCardFS file system active (improves access to SD card and data/media).

F2FS support on partitions /data and /cache.

exFAT support on SD card.

Multiple libraries updated with native Nougat sources.

GPS fast to get fix, precise and identifies American, Russian and Chinese satellites.

Stable and fast wifi.

Good battery consumption. Over 4 hours of display in 18 hours of use.

Without fast charging support (max. 1.3A over AC and 500mA over USB)

Video playback without bugs.

With Magisk 14.5b and the SafetyNet module it passes the SafetyNet tests, but the bank's NFC payment app still fails.

Over 50,000 points in Antutu.

It allows to install from Google Play certain apps (like Netflix) that sometimes don't do on some other ROMs.

Bugs/limitations:

Stable voice and data connection, without cuts in voice calls but with signal loss with fast reconnection (I use 4G auto directive). It completely looses voice/data signal and reconnect, the cut could lasts over a minute. It can occurs several times in an hour or could saty stable during hours, so random. It seems this bug depends on signal quality reception, it seems that the modem in this ROM have problems with signal reception. I tried other modems and they were far more stable but had the Bluetooth loss of signal bug :(

Random sound reproduction hang ups. Sometimes it needs to reboot to restore sound reproduction.

Exaggerated battery consumption with active Wifi, more notorious with screen off, when it doesn't enter well into DeepSleep. It happens to me in all Nougat ROMs. I manage with Wifi off normally and manually connecting when I need to make transfers of high volume data.

Wifi Tethering is broken, 5Ghz hangs and 2.4Ghz connects but it doesn't give access to Internet: I manage using USB tethering.

Send display wirelessly to smartTV doesn't work.

EngineerMode app can't save lot's of values or do calibrations (Gyroscope, Gsensor...). Previous RR Stable 17 build can do it right.

Bugs corrected in this build:

Some isolated FCs with certain apps that end up working (seems corrected with Kernel Adiutor fix).

Incorrect estimation of battery charge level. Chopped down from 40/30% to 30/20%.

Camera crash in night mode.

Extra configuration applied:

750 Mbytes of Z-RAM activated

Greenify configured to hinernate no critic apps.

Data & Caché partitions F2FS formatted.

microSD exFAT formatted.

Last GApps Pico, Magisk 14.5 (1456) and Dolby Atmos installed from Recovery

In summary, it's a very pleasant ROM for daily use, with a few bugs I can live with. Until we could get and Oreo at the level of this RR, I'll stay comfortably here.

As usual, thank you very much, [MENTION=7698574]sandstranger[/MENTION] and MAD Team, for your efforts in Jiayu S3 development, trying to bring the last improvements to our mature but capable smartphone.
