[Guide] Fixing major CM13 bugs - One (M7) General

This thread is meant to help you fix major cyanogenmod 13 bugs. CM 13 based ROMs are very nice, and probably the best way to being the android marshmallow experience to the m7 but they suffer from several problems.
Let's cut to the chase:
1. Camera: install cameringo from the play store, it works flawlessly. Also, cameramx works but expect some fc here and there.
One could argue that neither app is as good as HTC's stock camera app. But sadly they're the only options I'm aware of right now. Plus the m7's cam isn't all that good to begin with. If photography is your top priority you should consider another device.
2. IR blaster: install Asmart remote IR or ct remote from the play store. Both work for me but I recommend trying both and then keep whichever you prefer.
3. heat/battery issues: install no frills or set CPU app from the play store. I Peter no frills as it shows the current settings (so you can memorise them in case you decide to revert later). Kernel auditor is very good too.
Lower the maximum CPU speed to 1.134 GHz. You can change that whenever you need to, but 1.134 provides good battery life without compromising much performance. However before you run a benchmark or any other CPU hungry app remember to increase the max CPU speed back to the highest value.
set the I/o scheduler to bfq. cfq is OK but I prefer bfq. Google I/o bfq vs cfq to learn about the difference.
Set the CPU governor to intelliactive, interactive or smartmax. They're considerably better than ondemand. Smartmax results in lower performance but slightly better battery life. interactive is a very good all around governor. Intelliactive is an enhanced version of interactive. Experiment with all available choices. intellidemand is good too but I prefer intelliactive or interactive. Experiment with all available options your kernel provides. You should be able to figure out your favorite governor thru trial and error.

Thank you to you too
Have you unlocked your bootloader of your current device ? If so, read it ! If not, learn the benifits ! :victory:
What is this thread about ? It is a very brief explanation of every governors and schedulers to let you find the best combo for your device.
I've been searching a lot about informations about Kernels, Governors, I/O Schedulers and also Android Optimization Tips. No matter its Google or XDA or other android forums. I will go into it and try the best I can to find these infos. So I thought of sharing it to here for the XPlay users.
My main reason to share this is to benefit users for better knowledge about Kernels, Governors, I/O Schedulers and Tips on Android Optimization. I'm not aware of whether where this should be posted, its related to kernels, governors and schedulers so I think it would be best if I share it to here. Yes, I wrote it word by word with references.Happy learning. :angel:
After months on XDA, no matter its in a development forum or Off Topic forum. Users kept on asking what's this what's that. And I'm sure that not all members will understand what is it until they bump into my thread

Explanation
OnDemand
Brief
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point, OnDemand will rapidly scale the CPU up to meet the demand, then gradually scale the CPU down when it isn't needed.
Click to expand...
Click to collapse
Review
Brief says all. By a simple explantion, OnDemand scales up to the required frequency to undergo the action you are doing and rapidly scales down after use.
Conservative
Brief
It is similar to the OnDemand governor, but will scale the CPU up more gradually to better fit demand. Conservative governor provides a less responsive experience than OnDemand, but it does save batter
Click to expand...
Click to collapse
Review
Conservative is the opposite of Interactive; it will slowly ramp up the frequency, then quickly drops the frequency once the CPU is no longer under a certain usage.
Interactive
Brief
Available in latest kernels, it is the default scaling option in some stock kernels. Interactive governor is similar to the OnDemand governor with an even greater focus on responsiveness.
Click to expand...
Click to collapse
Review
Interactive is the opposite of Conservative; it quickly scales up to the maximum allowed frequency, then slowly drops the frequency once no longer in use.
Performance
Brief
Performance governer locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task. After that it returns the CPU to extremely efficient low-power state.
Click to expand...
Click to collapse
Review
Good at gaming, Really good. Disadvantages are it may damage your phone if too much usage.
Powersave
Brief
The opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.
Click to expand...
Click to collapse
Review
Set it to your desired minimum frequency and you won't have to look for your charger for once in a while.
Scary
Brief
A new governor wrote based on Conservative with some Smartass features, it scales accordingly to Conservative's way. It will start from the bottom. It spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as Conservative right now.
Click to expand...
Click to collapse
Review
Hmm.. Overall I don't see any difference. After I understand its main objective. I was very curious and decided to use it again. Results are the same.. No difference. Report to me if anyone has tested this.
Userspace
Brief
Userspace is not a governor pre-set, but instead allows for non-kernel daemons or apps with root permissions to control the frequency. Commonly seen as a redundant and not useful since SetCPU and NoFrills exist.
Click to expand...
Click to collapse
Review
Highly not recommended for use.
Smartass
Brief
It is based on the concept of the Interactive governor.
Smartass is a complete rewrite of the code of Interactive. Performance is on par with the “old” minmax and Smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Click to expand...
Click to collapse
Review
Smartass is rather the governer that will save your battery and make use of your processor for daily use. Like the brief explantion said " Smartass will spend much more time on lower frequencies." So logically you don't need for sleep profiles anymore.
SmartassV2
Brief
Theoretically a merge of the best properties of Interactive and OnDemand; automatically reduces the maximum CPU frequency when phone is idle or asleep, and attempts to balance performance with efficiency by focusing on an "ideal" frequency.
Click to expand...
Click to collapse
Review
This is a much favourite to everybody. I believe almost everyone here is using SmartassV2. Yes, it is better than Smartass because of its speed no scaling frequencies from min to max at a short period of time.
Smoothass
Brief
A much more aggressive version of Smartass that is very quick to ramp up and down, and keeps the idle/asleep maximum frequency even lower.
Click to expand...
Click to collapse
Review
In my personal experience, this is really useful for daily use. And yes, I'm using it all the time. It may decrease your battery life. I saw it OC itself to 1.4 gHz when I set it to 1.2. Good use. Recommended.
Brazilianwax
Brief
Similar to SmartassV2. More aggressive scaling, so more performance, but less battery.
Click to expand...
Click to collapse
Review
Based on SmartassV2. But its advantage is a much more performance wise governor.
SavagedZen
Brief
Another SmartassV2 based governor. Achieves good balance between performance & battery as compared to Brazilianwax.
Click to expand...
Click to collapse
Review
Not much difference compared to SmartassV2. But it is a optimized version of it.
Lagfree
Brief
Again, similar to Smartass but based on Conservative rather than Interactive, instantly jumps to a certain CPU frequency after the device wakes, then operates similar to Conservative. However, it has been noted as being very slow when down-scaling, taking up to a second to switch frequencies.
Click to expand...
Click to collapse
Review
Used it before. Like the name of the governor, I didn't experience any lag whatsoever. Another governor based on performance, but not battery efficient.
MinMax
Brief
MinMax is just a normal governor. No scaling intermediate frequency scaling is used.
Click to expand...
Click to collapse
Review
Well.. it's too normal that I can't really say anything about it..
Interactivex
Brief
InteractiveX governor is based heavily on the Interactive governor, enhanced with tuned timer parameters to optimize the balance of battery vs performance. InteractiveX governor's defining feature, however, is that it locks the CPU frequency to the user's lowest defined speed when the screen is off.
Click to expand...
Click to collapse
Review
A better understanding from the brief to you users, this is an Interactive governor with a wake profile. More battery friendly than Interactive.
Due to current kernels doesn't have these governors. I will be delaying the explanation, its very interesting. If you want it ASAP, post below

I/O Schedulers(thanks to droidphile)
Deadline
Goal is to minimize I/O latency or starvation of a request. The same is achieved by round robin policy to be fair among multiple I/O requests. Five queues are aggressively used to reorder incoming requests.
Advantages:
Nearly a real time scheduler.
Excels in reducing latency of any given single I/O.
Best scheduler for database access and queries.
Bandwidth requirement of a process - what percentage of CPU it needs, is easily calculated.
Like noop, a good scheduler for solid state/flash drives.
Disadvantages:
When system is overloaded, set of processes that may miss deadline is largely unpredictable.
Click to expand...
Click to collapse
Noop
Inserts all the incoming I/O requests to a First In First Out queue and implements request merging. Best used with storage devices that does not depend on mechanical movement to access data. Advantage here is that flash drives does not require reordering of multiple I/O requests unlike in normal hard drives.
Advantages:
Serves I/O requests with least number of cpu cycles. (Battery friendly?)
Best for flash drives since there is no seeking penalty.
Good throughput on db systems.
Disadvantages:
Reduction in number of cpu cycles used is proportional to drop in performance.
Click to expand...
Click to collapse
Anticipatory
Based on two facts
i) Disk seeks are really slow.
ii) Write operations can happen whenever, but there is always some process waiting for read operation.
So anticipatory prioritize read operations over write. It anticipates synchronous read operations.
Advantages:
Read requests from processes are never starved.
As good as noop for read-performance on flash drives.
Disadvantages:
'Guess works' might not be always reliable.
Reduced write-performance on high performance disks.
Click to expand...
Click to collapse
BFQ
nstead of time slices allocation by CFQ, BFQ assigns budgets. Disk is granted to an active process until it's budget (number of sectors) expires. BFQ assigns high budgets to non-read tasks. Budget assigned to a process varies over time as a function of it's behavior.
Advantages:
Believed to be very good for usb data transfer rate.
Believed to be the best scheduler for HD video recording and video streaming. (because of less jitter as compared to CFQ and others)
Considered an accurate i/o scheduler.
Achieves about 30% more throughput than CFQ on most workloads.
Disadvantages:
Not the best scheduler for benchmarking.
Higher budget assigned to a process can affect interactivity and increased latency.
Click to expand...
Click to collapse
CFQ
Completely Fair Queuing scheduler maintains a scalable per-process I/O queue and attempts to distribute the available I/O bandwidth equally among all I/O requests. Each per-process queue contains synchronous requests from processes. Time slice allocated for each queue depends on the priority of the 'parent' process. V2 of CFQ has some fixes which solves process' i/o starvation and some small backward seeks in the hope of improving responsiveness.
Advantages:
Considered to deliver a balanced i/o performance.
Easiest to tune.
Excels on multiprocessor systems.
Best database system performance after deadline.
Disadvantages:
Some users report media scanning takes longest to complete using CFQ. This could be because of the property that since the bandwidth is equally distributed to all i/o operations during boot-up, media scanning is not given any special priority.
Jitter (worst-case-delay) exhibited can sometimes be high, because of the number of tasks competing for the disk.
Click to expand...
Click to collapse
SIO
Simple I/O scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.
Advantages:
Simple, so reliable.
Minimized starvation of requests.
Disadvantages:
Slow random-read speeds on flash drives, compared to other schedulers.
Sequential-read speeds on flash drives also not so good.
Click to expand...
Click to collapse
VR
Unlike other schedulers, synchronous and asynchronous requests are not treated separately, instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.
Advantages:
May be best for benchmarking because at the peak of it's 'form' VR performs best.
Disadvantages:
Performance fluctuation results in below-average performance at times.
Least reliable/most unstable.

Yeah LuPuS has Lulzactive, Virtuous, Intellidemand, Lazy, Ondemandx, Lionheart and Badass added (but no mention of LionheartX).
Turbo kernel also has intellidemand but the parameters have been modified quite a bit (by me) to suit our snapdragon SOC's better. I think wedgess also put these changes into LuPuS too (at least one of the ICS/JB kernels he builds he said he did). The browser mode still has no effect AFAIK but in my experience it's more battery-friendly and better performance than on-demand (thanks mainly to dbus_input ramping). But many users have reported slightly better gaming experience with SmartAssv2.
Great reference, this will be of much help to new comers, thanks for the hard work you put into this.

Throughout my experience(mainly from observing CPU speeds during music playback), I found that:
Scary:
Ramps up to max after reaching a threshold (50/60% CPU load) then slow scales down to match as 50-80% CPU Load @ X MHz. After a while if load lowers (30-40%), it will clock down to match the 50-80% load. You will see a lot of 100% @ low MHz with this governor.
SavagedZen:
It maintains a 80-90% CPU Load @ X MHz for a fairly constant load. This one also scales based on the Max CPU Freq. settings. So the lower your Max CPU Freq, the better it is at maintaining the CPU Load/MHz balance (for music playback at least).
I didn't look at the source, so these are just from observations only. So I might be talking out of my ass.
Also, having good CPU Load at appropriate CPU Speeds may or may not contribute to battery life. No experiments showed that yet iirc.
Monitoring done via "Diagnosis - System Information" an app that generates an overlay with whatever information your want ie cpu load, speed, memory free, used, disk io, network io, etc.
Refresh rate kept at 5 seconds to keep CPU Load interference minimal (lower than ICS/JB CPU Info overlay from Development, Settings tab).
Great thread, this should be sticky!

There was, I ported it over a few months ago. But I removed it because it was causing priority issues. The latest BFS patch for our kernel has some critical bugs, so I ditched it. When I get ext# fixed in .60 kernel up and going I will probably take another crack at it, backporting one of the more recent 3.x BFS versions.
One of the LuPuS kernels might still have na laternative BFS version, but I think wedgess stopped building it for the same reason as me.

I see, there are really few BFS based kernels out there. BFS is better in my opinion so i would like to elaborate more about BFS to attract more users.
Btw, one guy in Xperia Mini, Mini Pro and Active forums had already successfully making it up and running for stock and CM ROMs. Its already hitted version 2.3
Maybe you could get some help from him ? Name is Mesa Kernel.

I was using v0.313 of BFS, it wasn't that hard - just had to adapt the patch for the Xperia's stupid kernel. That version is so unstable and buggy, in fact all 2.6.x BFS patches were so problematic that the official page has removed them.
I'll check it out, if he back-ported BFS for Linux kernel 3.0 and has them on GitHub, otherwise it would be easier just to do it myself. But I have other more important concerns for Zeus development right now, BFS doesn't really bring any significant performance boost (which is why it is continually rejected from AOSP inclusion).

Gamer Rom

I Need the Best gaming Lollipop Rom for I9505 with great performance and Battery life ?
That would be AOSP rom by the JDCTeam.
Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel
if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower
If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.
GPU overclocking isn't really stable, it actually takes away from the gaming experience.
How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.
Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.

What is the best performance setting for governor interactive?

hello guys, I made the root S7 edge Exynos version, and wanted to know how to set up the most of the interactive governor to improve performance, without too much worse battery, because with the performance governor the performances are excellent but it consumes too. thanks in advance to those who will help me. excuse me for my bad English.
I have to bump this. I am interested too. I installed super stock kernel that came with superman rom. And as I far I saw with synapse. There are tons and tons of possible adjustments. Around 20 or so governors. But some lead my device to be very instable. For instance Hyper I can not recommend. Instant crash and reboot.
As far the default setting is Interactive and it works well. Got like 12 hours with 3 hours Display on time. Performance is a bit lower in the moment as stock. But I have the bfq sqedular running. It's not super for Benchmarks but I hope it's good for video streaming.
i woundering this as well i got galaxy s7 930f running superstock kernel it has a lot of cpu profiles but non bearly works trying to select ,,,Barry allen profile fails ,,,,Intellimm fails,,,smartassv2 fails ,,,,
those that works are only electrodemand ,,, and interactive which as far as i know to close to original profile off the samsung own i think so idk how many tweaks there are in those
the profiles fails when i check A53 profile in synapse and A72 cpu profrile is it only the interactive cpu profile that you can use for those cpus since it says select interactive profile for those cpus ??
kinda confused a bit now .

Battery Life on CAF based kernel/ROM. Android 7.1.2

Please correct me on anything that I'm about to post below. I will correct it ASAP. Here Goes:
Here's what I've noticed since switching from a stock based ROM (Viper 9) with using EX Kernel to LOS 14.1 or AICP 7.1.2.
From what I've researched, these AOSP builds are using a MSM8960 kernel on our apq8064 board. It is also CAF based kernel as well. MSM8960 is very very similar to APQ8064. Which is why it works on our M7. APQ8064 support ended on CAF around ICS/JB days (from what I've skimmed in the CAF changelog). I've been researching different tunables on the interactive gov and the Ondemand gov. I'm trying to find the best settings to extend the battery while on 7.1.2. To me, it just dies too quickly with default gov tunings either on LOS or AICP. I'd like for other users to post their settings and which gov they are using while on 7.1.2. I'll post my settings as soon as I find the right combination on either the interactive gov or the OnDemand gov.
Edit: I've noticed that by disabling MPDecision and disabling at least 2 cores, battery life has improved. What I have been doing when I play a game is re-enabling the other 2 cores and switching to interactive gov for better in-game experience. I also set the min GPU freq. to 400mhz. Another tunable I adjust is the sync freq in the interactive gov. When gaming I set to either 918mhz or 1026mhz depending on how much load the app places on the cpu.
I've also been tinkering with L Speed app (root required as well). Enabling a profile caused my phone to exhibit a faulty touchscreen. Cherry-picking the optimizations I want doesn't have the same effect.
Which ROM supports customizable turntables or what kernel? I don't use ondemand anymore, it's always interactive for the CPU and simple for the GPU on my end.
i use a kernel manager like Kernel auditor or EX Kernel manager to adjust kernel settings. With those to apps you must have root.

Yes I have root, but i'm saying do you have a custom kernel?

technically it is. It supports dt2w and s2w. It was linked from the AICP 12.1 Nougat thread

Which ROM you are using?

Share your experience about ROMs of MI 9T ..
Which one do you use now and which one is your favorite and why?
It will help others to switch like me ?
Thank you in advance ?
I am too curious, as I've just bought a Mi 9T and haven't decided yet which ROM I'll try 1st !
From what I'm seeing, the options are MANY:
- LineageOS
- HavocOS
- AOSPExtended
- ExtendedUI
- Evolution X
- Pixel Experience
- Paranoid Android Quartz Alpha
- ....
- ....
I'm familiar already with LineageOS and AOSPExtended (with another device), both are REALLY good...
But from what i am reading, the most Feature Rich / Customizable of all is HavocOS ?
The best ROM to me, and the best customizable is MSM Xtended 6.0 with Anxiety as I/O Scheduler.
https://forum.xda-developers.com/mi-9t/development/rom-msm-xtended-project-v6-0-t4052911
Its customisation level is far beyond Havoc's 3.2, Lineage 17.1, AOSP Extended 7.0 and AOSip Quiche.

SOLD !!!!!!
indeed, it has so many features I'm seriously considering abandoning Xposed for good!
I stopped reading at:
Code:
[B]- System[/B]
Sensor block per-package
Smart Pixel
Wakelock blocker
Amazing !!! :highfive::victory::laugh:
can't wait to flash it clean!

I am curently using this ROM from 3 weeks.
What are the benefits of using Anxiety as I/O Scheduler?
Wich is the default? And how to change to the one you are using?

The customisation level of this rom is stunning but it isn't the smoothest.
According to the Aututu benchmark, this rom sucks during a specific test: "ROM random access" that gives only 4600 with the default I/O scheduler CFQ.
Setting Anxiety instead increases this score to more than 10000. This is like unleashing the rom.
My experience of the impact of this score to the everyday use come from my previous phone, the Redmi Note 5, much less powerful than the Mi 9T.
With this score at 1700, browsing a long list was laggy as hell, a real pain to the user.
With this score at 7000, browsing the same list was smooth.
That's why tweaking the I/O scheduler to boost the result to this benchmark test is useful, not only to get a higher score.
The scheduler can be set through any kernel tweaking app.
I use Smartpack Kernel Manager, but it isn't the only one.

I get now in antutu 11000 score for rom random acces with the default setting
My bad. I have many apps installed and perhaps one of them has waken up to do its business during the benchmark.
This bunch of apps also explains my score stays lower than yours.
I have to do these tests again to evaluate with more reliability the gain of the I/O scheduler Anxiety in place of CFQ.
Anyway, the MSM Xtended is the best rom for the Mi 9T regardless the benchmarks scores.
EDIT: I confirm I have to apologies. I've no clue what went wrong during my previous tests because the new ones gives different results.
They show that changing the I/O scheduler is pointless.
Here are my results with CFQ then Anxiety:
I'm getting 267000 points. Is ok. Any other settings we cand do for better perfomance and battery?
I've found why I've gotten only 4600 to the Rom Random Access Antutu test while the actual score is 11000:
I got the low score from MSM Xtended 6.0, but an earlier version that had another kernel the actual from 2020-02-17.
That means this score depends much more on the kernel than the rom.
I'm on MSM, tried Kernel Adiutor or Smarpack kernel manager.
When kernel manager started, CPU minimum frequency is forced to be 1.2GHz and no lower, even with CPU section untouched.
Without kernel manager, it can get as low as about 600MHz. So I gave up changing scheduler.
But anyway MSM is best rom as it is. It is more customizable than even havoc.
edit
I tried again and saw CPU frequency going down. Now let's see the scheduler.
I'm using msm extended as well but I'm having issues with Netflix, same for you guys? I get the 5.7 error. There is this magisk tweak but it reduces widevine to l3
