[Xiaomi Redmi Note 7 ROMs, Kernels, Recoveries, & O] Fak07:
My review on this rom.

(Originally Spanish but too lazy to not use Google Translate lul)

My ROM analysis AOSP Evolution X 4.20 Predator Kernel (I hope it works: D).

**This mini review is aimed at those who do not decide between unlocking the bootloader or staying in stock.

**You have to know at least a little to know what type of user I am when using the device since that is what the battery consumption will be based on, among other things. I had the Redmi Note 4 Global 2 years ago, and then I switched to the Redmi Note 7 and had never tried the custom roms,

always in global stock of each version of MIUI until 3 days ago when I unlocked the bootloader and installed the ROM verbatim using the steps provided by the switch in the XDA forum.

**I never play on cell phones, I consume a lot of videos and social networks, I never use brightness to the fullest, even if I don't see in the sun,

Regarding the battery, I never let it drop below 20% of capacity, I never charge it with fast charge so as not to deteriorate it in the long term unless I am in a hurry since I usually use each phone for at least 2 years and I am a patient who monitors every day consumption.

The following scores are to be based on and take as reference my personal experiences using various operating systems and user interfaces.

FLUIDITY AND FUNCTIONALITY: 9.

**Flawless, so far no jerk the entire interface fully fluid,

Zero lags in scrollings of social networks like Facebook or Instagram with videos playing. Transitions very, very smooth compared to MIUI that could give some jerks on certain occasions.

**The multi task does not always keep all the applications that we open, for example,

If you open Facebook Instagram Youtube and WhatsApp at the same time, chances are that when you change from the last one you opened to the first one, it will not keep it in memory.

The "increase tactile response" section within the settings is quite noticeable regarding the problem that some Redmi Note 7 have when pressing the letter "a" on the keyboard (which costs a good grip and is quite annoying due to the manufacturer of the Tianma screens ) this problem is not completely solved,

but it helps a lot to eliminate that annoying hardware defect.

PERSONALIZATION: 7.

**Compared to pure Android 10 as it is Pixel Experience (as I documented in reviews and YouTube videos since I have not used it personally until now) it has more parameters to change, but so far. Beyond some little colors in the interface,

restart options and the "Evolved" section within Settings is still Android 10 semi stock (which was the developer's goal since they were looking for a clean interface), and coming from a system like MIUI that is highly customizable perhaps it contrasts with the design sober from the google rom.

BATTERY: 9.

As I said above I am sick of the numbers and consumption, I had expectations for this rom because Android 10 base already handles the background processes in a more neat and efficient way, let's add to that that does not come with bloatware or applications unnecessary (not even Maps or Youtube) to open in the background, the result is great

.

**Mostly used with WiFi due to quarantine and 85% brightness (all colors reduced to 90% to reduce phantom screen which minimizes maximum brightness logically, which would be about 75% brightness in MIUI for example). As the attached screenshots show,

8 hours and 21 minutes of total screen without exhausting that remaining 1% that at most would give me about 5 more minutes at most.

**The fast charge I am not sure that it works, for the same use a Turbo charger for Moto Z Play of 15 Watts (in MIUI it works correctly),

and compared to the 10 Watts of the original charger the amperage shown in the screenshots of the Ampere application shows that the mAh levels are practically identical, perhaps it is a Kernel problem and then they solve it, but today, it does not work.

Charging time from 0% dead to 100% 1hr and approximately 50 minutes using stock charger.

**Something that should be highlighted about this ROM is the low standby battery consumption it handles, practically nil. Surely it is due to the architecture of Android 10 and the handling of apps in the background that I mentioned above added to the custom Kernel,

but coming from MIUI 11 that at night perhaps consumed me sometimes up to 3 or 4% without having apps open, this rom does not consume even 1% (last night I went to bed with 87% and after 7 hours I woke up with 86%, so that in that aspect very, very well.

BUGS AND BAD DESIGNS:

- Notification LED does not work up to date (although it does when it loads).

-

It does not have a 24 hour format on the clock.

- The backward gestures do not work on any keyboard (Gboard and Swiftkeys at least) while it is open, so you have to make the gesture above the keyboard area, which becomes too annoying (perhaps this section is directly from Android and not from the custom rom,

but it is also a dung and is present in the rom).

- The menus are designed like the eyelet, not very intuitive, they make you confused and even make you abuse the search bar within Settings due to the clutter of options there are.

- In WhatsApp when you select the camera to send a photo while in a chat

When switching to the front mode of the camera it has an impressive lag that lasts a few seconds until it changes (it works at least).

- The volume bar is very short, which often forces you to have to use the physical buttons to control the volume at ease.

-

The notifications that come to you with the device blocked will turn on the screen, this would not be a problem if the Note 7 had an OLED panel, but it does NOT have it (plus add the quilombito to configure it).

- The Evolved "Papers" app that contains wallpapers cannot be removed.

GHOST SCREEN:

I had read here several times that taking 10% off each color on some roms reduced the effect, and indeed it did. In Settings / Display / Live Display / Color Calibration I set Red to 90%,

Green in 90% and finally Blue in 86% so far I did not notice the ghost screen that occurred to me when using Chrome in incognito mode (it has colors very likely to mark this effect, such as the dark gray that the app uses in that mode ). Zero traces at the moment, although as I mentioned above,

This setting REDUCES THE MAXIMUM BRIGHTNESS OF THE PANEL, so if some had a hard time seeing the celu in the sun, now it will cost a little more.

CONNECTIVITY AND MULTIMEDIA:

**WiFi ok; Bluetooth well; 4G (operator Tuenti Argentina) fine; Headphones fine; File transfer to PC fine; GPS (Maps) ok; Speaker speaker good;

Atrial speaker good, volumes correct; Infrared port does not turn on the TV but I think it is because they updated the apk I was using, as soon as I can I will try something else and edit this section.

GAMES AND PERFORMANCE:

*As I mentioned I am not a user who plays on the phone, but I did download Antutu Benchmark 3D and did the test,

I attach the score of the Redmi Note 7 stock and mine with Evolution X.

PERSONAL CONCLUSION:

**To be a Custom ROM I thought it was going to be much less polished than it is, the truth that for day to day it seems great, very good autonomy and fluidity, minor errors mostly, nothing that affects the daily use of the phone.

A super complete rom that the only thing that makes me miss MIUI perhaps is the Second Space that comes by default (because these days I was using it on time) and the gestures that were perfect compared to those of Android 10 that although they are not bad , the detail of the keyboard that I mentioned before is re breaks balls. Super recommended,

I am not going back to MIUI at the moment.
