RR-N-v5.8.4-20170810-markw-Unofficial Review

Introduction

This is a short review of the 10/8 5.8.4 version of Razziell's RR. I'm writing this review so more people might try out this rom which in return might help develop the rom further. Razziell mentioned that XDA is not his go to forum and that he hasn't received much of any help here, but I'm sure that we can change this!

I have tested the rom for a couple of weeks while traveling across Europe. Since I had absolutely no clue about anything abroad I had to use the phone at all times for navigation, train departures, hotel booking and a bunch more.

State of the rom

Instead of going into detail directly I want to make clear that this rom is perfectly usable already. It is very stable and I'm yet to experience a single reboot in the latest update. There is absolutely no reason to dual boot with MIUI for instance. It's not bug free by any means, but MIUI isn't either.

Stutter and lag

Some users on XDA have mentioned stutter and lag in the latest update. I wouldn't say that this is more noticeable than in previous versions, but it does certainly exist. More often than not the home screen has to be redrawn and frequently apps seem to be unresponsive for a second here and there. I was able to fix this issue by installing the Faust Kernel. After flashing, the rom is as responsive as the official MIUI if not more.

Camera

The main issue with this rom in previous versions has been the camera. Video recording would not work at all with the stock camera app. This was later fixed, but added another bug with crackling audio on recording. Another bug that was introduced was that the front facing camera had a green tint in low light. The latest update has fixed even these bugs and now the camera works even better than in MIUI. While traveling I used the camera extensively to take photos and had almost no issues. I did experience that the photos were not as sharp and vibrant as on my girlfriends flagship phone, but that's without a doubt because this is a budget phone.

GPS

When traveling I used the GPS and compass more than anything and there are noticeable issues. The compass is not as accurate as on MIUI, not even close to be honest. A lot of times I found myself walking in the wrong direction or believing I was on another road than I was. I became used to it after a while and was able to find my way, but still a big issue. I surely hope that this will be fixed in a future update if there is any.

Mobile data

I did try mobile data with roaming in several countries and it seems to work just fine. Of course LTE isn't as stable as on a phone made for the European market. I had to chose networks manually a few times and also had to reboot once or twice when the phone had no reception at all. My girlfriend had the same issue with her flagship phone so I wouldn't call it a bug.

Battery

Battery life is excellent on Xiaomi Redmi 4 Prime and I would say it still is with Resurrection Remix. On average I did manage to get two days of use out of the phone on one charge. Considering I used the phone a lot I wouldn't call the battery life bad at all. Battery on MIUI was out of this world and way better, but I still would prefer using this rom and give the phone an extra charge here and there. There is a bug when charging to 100% though. A lot of the times the charge does not seem to deplete and a reboot is necessary to see the actual battery percentage. This is not a big issue though, just something to keep in mind.

Final thoughts

The latest update with the Faust Kernel is a great experience. Considering I have only noticed a few bugs (the biggest being compass accuracy) I would call this the best rom on Xiaomi Redmi 4 Prime and that is including the official MIUI, Epic rom, Xiaomi.eu and RR 5.7.4. It would sadden me greatly if this rom is not developed further and I would love to see Razziell make a Resurrection Remix for Android 8.0 when the time comes.

Drop me a line or give me a quote if I left anything out. :)
