Xiaomi Teases MIUI 9 through Screenshots – Most Likely to Release This Month

1 comment
MIUI 9 - Banner

Xiaomi may release the much awaited MIUI 9 this month. Recently, Xiaomi’s Vice President in Marketing, Huan Long posted a few screenshots of upgraded OS on the Chinese microblogging site, Weibo, hinting at the release.

Xiaomi’s CEO, Lei Hun had earlier confirmed that MIUI 9 would be more powerful and smooth, hinting at not many visual changes.

Official Screenshots:

Official Teaser Screenshots
By analyzing the screenshots of home screen UI posted on Weibo, we can say that MIUI 9 doesn’t feature many changes in UI apart from new icon design and theme. The clock widget is centered and has a different design from the previous version i.e. MIUI 8.
Also the recents window is almost same as before except the background. In MIUI 8 we got single solid color/blurred background in recents, but in MIUI 9, as shown in the screenshot clearly, the wallpaper be used as the background.

It has already been rumored that MIUI 9 will feature some awesome new features, like – split-screen multi-window mode, picture-in-picture mode, quick reply, advanced doze features to save battery life and many other tweaks.

Multi-Window Support with Split-Screen

Split-Screen Mode

Multi-window support is must for quick and easy multitasking and official Android 7.0 (AOSP) Nougat has already included it. And Split-Screen is just great for tablets and phones with larger screen. In split-screen mode we can use two applications simultaneously, by splitting the screen into two parts. It should be noted that Nubia UI has already included this feature even in older version of Android, tracing back to Kitkat!

And now Xiaomi is looking to bring this feature to its MIUI 9.

Picture-in-Picture Mode

Picture in Picture Mode

It might be one of the most wanted features for MIUI fans. LG, Samsung and Nubia has already this feature. This feature lets you view multimedia in a small window at the top of the display while letting you use your current application at the same time.

When the update will release?

Teaser posted on Weibo
At the present moment it cannot be said clearly when will the new OS be released by Xiaomi. But we expect it to release this month or the next, as the rumors say. But it is sure that MIUI 9 will be coming with Android 7.0 Nougat. It is very much disappointing that Xiaomi is releasing its Android Nougat update when Google has released Android 8.0 Oreo. But still, MIUI fans are excited about the MIUI 9 release.

Xiaomi has recently published the list of 14 smartphones which will get MIUI 9 Nougat update: Mi4c, Mi4s, Mi Note, Mi Max, Mi 5, Mi 5s, Mi 5s Plus, Redmi Note 4X, Mi 6, Mi Max 2, Mi 5C, Mi Note 2 and Mi Mix. And all the upcoming smartphones from Xiaomi are expected to run on MIUI 9 Nougat.

MIUI 9 Update

Also the other Xiaomi devices like Mi4i, Redmi 2 (Prime), Redmi 3, Redmi 3s (Prime), Redmi 4 etc. will get MIUI 9 update but without Android version upgrade.

And devices like OnePlus One, OnePlus 2, OnePlus 3, flagship Samsung devices, flagship Motorola devices and Nexus devices will also get MIUI 9 ports later on.

How to Choose Best Headphones by Looking on Specs

1 comment

How to choose best headphones on the basis specifications • Earphones Specifications Explained • How to know if headphones have good Bass, Clarity and Treble

There are variety of headphones (or earphones) available that it becomes difficult for us to choose the right one that suits our purpose.

We may sometimes find that a budget headphone may give a better output than a costly one. This is because everyone’s taste is different, some people like bass and some treble, some love loud music and some people love soothing music. So every headphone may not suit everybody.

So how to choose which headphone is best for you. For that first let’s discuss the different types of headphones and their features. Later on we will discuss in detail about different specs of a headphone like frequency range, sound pressure level, impedance etc.

Types of Headphones

There are basically three types of headphones.

1. On-ear Headphones

On-ear Headphone
On-ear Headphone
On-ear headphones or supra-aural headphones are those headphones which rest on the top of the ear. They are basically more light weight than over-ear headphones and are easier to carry. As they sit on the ears, there may be some leakage of sound and may not provide noise isolation as good as over-ear headphones. Sometimes they may be tight and my squeeze the ear too tightly to make it uncomfortable for you to use it for a long time. So, it is crucial to choose the correct pair that fits perfectly.

2. Over-ear Headphones

Over-ear or circum-aural headphones enclose the whole ear. So they are more comfortable for a long term usage. As they encase the entire ear, there is no leakage of sound so it gives better noise isolation. Also because of this bass is better in these type of headphones. Since they are bigger in size they are less portable than other type of headphones.

These type of headphones are further divided into two types:

Closed-Back Over-ear Headphone
Closed-Back Over-ear Headphone
Closed Back: These are most general type of circumaural headphones having the back of earcups sealed. Because of this it provides superior noise isolation and more clear audio.

Open-Back Over-ear Headphone
Open-Back Over-ear Headphone
Open Back: This type of over-ear headphones has the back of its earcups open. These type of headphones have more sound leakage but sometimes they are preferred by the audiophiles as they provide more natural sound, they feel.

3. In-ear Headphones

In-ear Headphone
In-ear Headphone
In-ear or canal headphones fit inside the ear canal. Since they fit inside the entrance of the ear, they provide better noise isolation and good quality music. These type of headphones come with different size of tips, so you need to choose the one which fits perfectly in your ear canal otherwise it may be loose and will reduce noise isolation.

These were the different types of headphones, now let’s discuss about the different technical specifications which we see on the box of headphones or on its site.

Technical Details or Specs

Frequency Range and Frequency Response

Human audible frequency range is 20Hz to 20KHz. Different headphones come with different frequency range (e.g. 17Hz – 22KHz, 20Hz – 22KHz etc.). While choosing a headphone it should be noted that lower the minimum frequency more will be the bass and higher the maximum frequency more will be the treble. And the response or output that we get at different frequencies is called frequency response. Some headphones contain a chart for frequency response. By studying the chart, we may understand about the output of the headphone.

Driver Size

Driver is the most important component of a headphone which creates the sound. It converts electrical energy into sound energy and has a diaphragm which vibrates to produce the sound. It is generally regarded that larger drivers produce better quality audio, but it is not a fixed rule. Size of a driver is measured by the diameter of the diaphragm in millimeters. So, a driver size of 40mm or above is good for an over-ear headphone. The in-ear headphones contain a driver of 8mm to 12mm. Some in-ear headphones contain two drivers, one for handling bass and other for mid and high frequencies. And some premium in-ear headphones contain even more than two drives.


Impedance is the electrical resistance produced by a headphone. It is measured in Ohms. Headphones with higher impedance require more power. So, impedance is generally less (below 32 Ohms) in headphones designed for mobile devices. So, headphones for mobile devices use a low voltage and require a high current which sometimes creates a hissing sound. On the other hand, high-end headphones have a higher impedance (above 300 Ohms) which produces clear sound but require a dedicated amplifier to power them.
In some cases, impedance mismatch may also create sound distortions and noise. So, higher impedance headphones should not be used with smartphones and low end headphones should not be used with high-end audio systems and amplifiers.

Total Harmonic Distortion (THD)

In some headphones we may find some sound distortions at higher volume levels. This happen when the diaphragm could not vibrate as fast as required at higher volumes. This creates a sound distortion called Total Harmonic Distortion (THD). Most headphones have THD of less than 1%. Lower the THD better will be the sound output at higher volumes. So, many premium headphones have a THD of 0.5% or sometimes even up to 0.1%.

Sensitivity and Sound Pressure Level (SPL)

Sensitivity of a headphone may be described as its efficiency. Sound Pressure Level indicates the loudness of a headphone. SPL is measured in Decibel SPL per milliWatt. The SPL of most headphones is in the range of 85 – 120 dB SPL/mW. So, higher the Sound Pressure Level of a headphone, louder will be its sound output.

Noise Cancellation

Some headphones have noise cancellation technology. They have a dedicated microphone which records the ambient noise, then creates an inverse sound wave and feed it back into the headphones to effectively cancel out the noise. It works best for constant low frequency noise (like sound of the engine of an aeroplane) but does not work for higher frequency noise (like people talking around).

Noise Isolation

Noise Isolation means blocking external noise by the physical design of the headphone. As we have already discussed before, noise isolation is higher in in-ear headphones and over-ear headphones with closed back.

So how to make the choice?

Understanding a headphone configuration is a much complicated task. But still we may try to find the headphones that best suits our purpose by taking into account the above factors, our environment and the type of music we love to hear. People’s review of the headphone may also become an important factor affecting your decision.

Workaround: Just change the default SIM for Data through settings or use the provided FixSignal app.

Cannot set up pattern lock in Second Space (though PIN and Password lock works)
This is a bug of MIUI PatchROM source so cannot be fixed from my side.

Workaround: Use PIN or Password

PTP not working (MTP works though)
No fix yet.

Some Tips

How to get global Music app and MIUI Browser?
Ans.: You have to edit the build.prop.
Change "ro.product.mod_device=tomato" to "ro.product.mod_device=tomato_global"
Note: This will also reduce some features of developer ROM like Root access, Quick search etc.

How to enable on-screen Navigation Bar?
Ans.: You have to edit the build.prop.
Change "qemu.hw.mainkeys=1" to "qemu.hw.mainkeys=0" and reboot.
Then go to Settings > Other Settings > Disable hardware buttons

Then select your desired profile from the list (Battery | Balanced | Performance)

Q. How to enable Google Search widget in recents in QuarkOS 3.0?

Ans: In QuarkOS 3.0 you may find that Google Search widget has been removed from recents screen. This happened because Google Search got embarrassed because of awesome unified search widget of Evie, just kidding :p

So, to get it back install Google Now launcher (or any other) and then make it default and disable Evie launcher from Settings.

Then reboot your device. You will see that Google search in recents will come back happily.

Then you can revert back to Evie launcher.

Bugs and Workarounds

Known bug: Led notification light not working for notifications when charger is not connected. [But works with USB plugged]

Workaround: Use Light Flow Pro app (or LED Blinker app) to set led notification for your favourite app. Set the LED to “Always on”.

Limitation: Since the ROM is fully based on AOSP, there is no native support for NTFS and exFAT file systems.

Workaround: Use Paragon NTFS, ExFAT Mounter app from Google Play.

Some Tips

The ringtones are set to 'none' by default. So select your favourite ringtone after flashing. ("Sound picker " app is preferred)
Use Xperia Camera Widget to access all the Camera addon apps.

For Devs and Advanced Users

After hours of hardwork I have finally made patchable source of QuarkOS. Here it is:


This source contains all the history of methods that I used to make the ROM.

Now Devs of different devices can try making with different bases like MM, N, MIUI, Lineage etc.

Now users can know the secret of making ROMs by modding. And there's lot to learn.

I hope to see QuarkOS for other devices too. :)
