I'm using my Redmi 4x for music playback in my car and I was searching for the best equalizer app. I found that most apps support 5 bands, while a few manage 10. Is there a 5-band-limit (and those 10-band-EQs are cheating) or does the Redmi support 10 different bands? If my ears don't lie I can hear en effect from all 10 bands. Unfortunately all of the 10-band-EQs have problems with saving presets or simply crash when selecting a preset. Any recommendations?

Although the Nexus 4 works fine for the most part, the firmware seems to have been "rushed out".
Hopefully LG and Google will release an update soon but in the meanwhile it won't hurt if a few brave
souls dive in and attempted to fix things. I myself, learn best by trying to fix broken things, even if I don't always succeed.
I will put together a list of what is broken/needed and update it to the best of my knowledge. Please post to this
thread to tip me on possible issues and solutions. Please include credible links and pictures in your posts.
1) USB OGT does not work.
Google changed it's documentation to state that USB OTG is not supported on the Nexus 4.
Relevant thread --> http://forum.xda-developers.com/showthread.php?t=1966864
Problem:
It's unclear whether this functionality was disabled in hardware or software.
However it was verified that the Nexus 4 is not able to supply power to external devices.
Any future solutions will most likely involve a powered USB hub.
2) FM Radio does not work.
The Qualcom SoC supports FM Radio and it is unclear whether this functionality was disabled in hardware or software.

3) Poor camera performance
Problem:
Low-light performance of the Nexus4 camera is noticeably worse than the LG Optimus 4X that uses the same camera sensor.

Leads:
The camera needs to be properly calibrated. Since that is not a trivial task developers might instead
look into swapping the camera drivers on the Nexus 4 and the Optimus 4X.
4) Voice call recording disabled
Relevant thread --> http://forum.xda-developers.com/showthread.php?t=2079016
Problem:
The Android SDK provides a Voice Call audio stream for recording. Many great apps already take
advantage of this feature. The Nexus 4 however does not implement this.
Leads:
ALSA could theoretically be used to open a Voice Call interface in the Audio Mixer and routed out to a PCM stream.
The stream could be exposed to the Android SDK "MediaRecorder.AudioSource.VOICE_CALL".

5) Sound recordings are very noisy.
Problem:
Sound recordings, sound on video recordings and the sound of VoIP on the Nexus 4 are unusable.
Voice calls however sound OK so I'm confident that there's room for improvement.
Leads:
I'm using ALSA to look into the Audio Mixer. The recording streams seem to have the LP filter set too low
at 4Hz, I can try changing that. Another theory is that the gain is set too high causing distortion. So far I
did not see a control to enable AutoGain.

6) Ability to switch to a preferred 3G band.
Problem:
The *#*#4636#*#* menu crashes when trying to change the preferred 3G band.

7) (FIXED) The screen colors exhibit a yellowish tint.

Give me a downgrade to 4.1.2 and a fix for the 3g connection issues.
everything else is fine
I tend to record quite a few videos of live music, and need a phone that isn't going to completely destroy the audio quality. My Note 8 and now Galaxy S10 do fairly well, but I'm really wanting the camera features and bigger battery in the Huawei P30 Pro.
Anyone know how Huawei has generally been with audio quality while recording video, or (better yet) have a P30 Pro and have tested this?
My Mate 9 Pro and the P30 Pro seems to have fine audio recording when using default camera apps. Third party apps all recorde audio at extremely low (unusable) volume, but it might be that the apps need to be updated. I hope it's not some stupid limit set by Huawei. That would make no sense whatsoever.
Quality management is a hard job and not all bugs can be found from a single (or a few) developer(s) in a practical time. So I want to create a list of bugs we've found in our different provider and version dependent Android versions.
I start with my Sprint G8 Android system:
FW Version: G820d
Bug 1: APN settings are greyed out. Only with service code and ##data# changes in settings are possible.
Bug 2: Don't know how much LG is responsible for this, but in Netflix only DRM Widevine Level L3 is used for streaming. I don't care that much about resolution on a relative small smartphone display,
but at least HDR would be fine for better shades in dark movie scenes. So streaming in Netflix will only happen in SD quality.
Bug 3: DSD audio files will not be played anymore by the G8 natively. Found from the V50 friends in actual Android 10 update, and approved on my device.

The Bluetooth audio codec defaulting to ACC bug from 9 is still present in Tmo Android 10 update. Still defaults to ACC despite aptx and higher allowed to stream on headphones. _NOACC has no effect.

NOACC works on Sprint version since Android 10 update, but the max volume for my bluetooth earpiece is much lower than Android P.
I now use wired earpiece only. :\
Sprint
- Unable to access roaming settings
- Volume slider missing from notification area
- Can't hide nav bar in apps
- Comfort view won't auto engage at set time occasionally
- Playlists ignored by android, despite being in same place
- Choppy video recordings under extended + maximum mode. Also laggy viewfinder in both saving modes
- Roaming reduction battery drain (roaming was disabled before updating)
no duration for call log
No duration for a call in call log. This is major flaw.
My accessibility options crashes when I tap on it...
Oh and Kiwi browser crashes when going to Landscape.
On the T-Mobile be version when getting a pop-up in any browser (such as the page asking to share your location), there is no ability to tap "yes" or "no"." Pressing the back button is the only way out.

I own a Xiaomi Redmi K20 Pro. As you might be aware that it rocks Qualcomm Snapdragon 855. Please check out the specs of SD 855 on the web, if you don't know already.
The chip supports HDR10+ recording at the hardware level. While I understand that you need to have a supporting camera lens to record with that color gamut, I have found it to be disturbing that the metadata of the video recorded on the camera shows Rec.601 as the record profile with Y'Cb'Cr of 4:2:0.
I want to know whether is it possible to record on this device in Rec.2020 or at least Rec.709? Does anyone have any idea?
Additionally, the chip supports 802.11ax(which I guess uses 60GHz spectrum). How to check if the fone also supports WiFi connection in this band and the WPA3?
Wow, surprisingly not a lot of people are aware of this issue.
You cloud try FreeDcam from GitHub.
You'll have to change the profiles via profile editor.
I am able to record videos in Rec.2020 using the same app on Asus 8Z.
Check out the attached screenshot to see my settings to shoot video in 10bit Rec.2020
Though, utilising the same is a pain in post processing platform (Davinci Resolve), but I fortunately found a the correct way to transform the color space.
Hello all, I have a good FLAC collection and K20 Pro as well. I use hi-fi audio setting on K20 Pro. However, MIUI 12 has been getting cancerous by the update and I want to switch to a clean custom rom that supports HI-Fi Audio Playback like stock rom. But I am not able to find any list of roms that support the feature. Can anyone help me out curate a list of custom roms that support Hi-Fi playback feature of MIUI Stock Rom. Thanks in advance.
