Bugz bugz bugz First the app worked like a charm. Lately after updates, it stopped applying settings on boot. Every time I restart my phone, had to hit the X button.

Blake Duncanson

It'll work fine for like 3 days then everything will start crashing and then my phone will freeze and after I finally get it to reset it tells me no UCI support. However if I go and clear all of the date for the app it'll work perfectly fine again until the next time that it does it

Surach Man

Cant open I dont know why. I cant open my synapse. Its fine before. Please fix it.. :)

eric bloss

Awesome kernel control. I would love to see pre-built color control options several other apps currently are using.

Kristian Naglic

Really nice The only thing that bothers my is that it sometimes hangs when switching more than 3 settings at once and sometimes causes the app to crash. Otherwise does the job well.

Tom Rebel

Not working Not working in OnePlus One with VM12.1 5.1 ROM. Says device not supported...

Ash Frost

Great app for free! Good app, good functionality, very popular amongst the xda community, and free! More often than not, issues with this app are due to operator error and not down to the developer.

Igor M.

Good but buggy Regarding the options it offers, this app is great. But, it has many bugs. Profile restoration and import does not work, false detection of failed boot settings, CPU voltage bug when using global option.

Michael Barbara

Developer Dev gets butt hurt leaves bad, and stupid reviews on other apps..

Grant Mendes

Simply awesome Makes my oneplus even better.

Vivek Jindal

i wish if developers update the app and fix bugs i guess devs are having a hard time due to kernel fragmentation?

Suraj R

Works like a charm. This is the only app that works with xcelerate kernel. Downside is that it only works with xcelerate kernel.

Chris Pyle

Works Great It interfaced with the "Vindicator" kernel flawlessly on my Nexus 6 and allowed me to tweak my kernel as advertised. I have to wonder if issues are "pebcak" or should it be "pebcap"?

Greg Smith

Needs UI upgrade bad. Works fine but needs a material upgrade bad.

Upakul Rox

Crashes and Age old UI Occasional crashes and the UI looks like 1975. Rest all good.

Devansh Kumar

Best all-in-one app Best kernel tweaker so far with loads of customization options.

Sean Humes

Bugs Great app. When it works. For example, after updates, it's not applying settings on boot and the inability to change the CPU governor.

Shimabde Koerniawan

Cool Awesome

Louis Narvaez

Don't working Don't working when others do...

aqila zafa

Nice but Nice but i realy hate the user interface material theme please

Daryl Bennett

Works... Lots of options Horrible UI flow. Crashes often. Not for the faint of heart

Milan Kojić

Awful Device not supported??? Nexus 4.

Kevin You

Very good Great app to customize kernel, material design would be awesome!

Don King

This app is awesome.

Jiramet Kebwai

want a restore to default button

oxygen os

Stopped error The application gives an error and closing when restoring profile. Busybox and ak kernel is installed and i am rooted.

Trushant Patel

Limited Options Only 2 options available to me 1)Hotplug 2) Advanved . How am I supposed to change CPU & GPU settings?

Darshan M

UI can be improved.

Эдуард Артюх

Doesn't work.... Universal Kernel Manger already installed, but app doesn't work...

Сергей Тимченко

Please add Russian language

Стас Калишевич

5 Material theme please

Alex Sosykin

Super Best kernel and soft, respect bro

Bona Fide

wacky bugs. i used this app on kitkat just fine, but on lollipop it's the cause of all the crashes in my apps and everything starts to force close. i installed another kernerl app and uninstalled this one and everything went smooth again. so it's this.

sushant mhatre

Best out of all just need a good ui make over now Main thing I personally loved is this is the only kernel app which remembers my saved settings,profile,global voltage tweaks correctly. Hats off to Dev. But now its probably the time to update its UI, cause that why I started using other apps.

Prashanth Meesara

Force close when restoring There are lot of features and best to tweak kernel but the one most annoying problem is that it just force closes if I restore a saved profile and only way to get it working is by clearing app data, please fix this

Joshua Connelly

Restoring profiles not working Restoring profiles on AK Kernel 262 & 265 doesn't work. The .Tgz profiles don't stick and "none" is there after trying to apply profile. Please fix. Oneplus One, Exodus 5.1.1

Jamie Taylor

Good but Great wide variety of features but it doesn't save.. I have to re apply it all the time and there isn't even a save profile

Sean Duckworth

Love It I'm no kernel expert..but I can even use this app..really like how he describes what each settings is.and in a really crystal clear discription as well.5 star great to..using on kitkat hyperdrive rom..Nadia kernel with full support from this app..the dev said to use this app..and I've set up every setting myself for the very first time not using any other user profile..and its cause how clear he explained each settings..and after boot sequence was over after boot up finished all went well..

Paul Tropea

Best kernel app bar none No matter what your kernel's options, you can configure them here. Options actually stick too, and when they don't you're made aware, not just surprised by reset configuration. For novice users it may cause a couple headaches, but for advanced users it saves so many more. Only issue this app has is the hard coded theme that breaks themes - get rid of that so it doesn't conflict with full CM themes and this app would be perfect. Still 5 * as is though.

Tushar Choudhary

All okay but.. I can't save my current profile. It always says that I haven't entered a name although I've done it! Please fix this. I'm using Bacon running CM 12.1 with AK Kernel.

Aldy Zen

Work perfect on my xiaomi but the interface is very old and the update of this app is very late please make this app beter than other kernel tools with new feature and new interface

Anonymous Anonymous

Dont work on AICP Ive had this before tho, its amazing so i rated accordingly.

Ian Jackson

Very unstable and a pretty confusing UI. I like it, but after a few OTA's it made my phone very unstable. I uninstalled it and got rid of UKM and it's stable again..

Hassan Shah

Bugs It says Device not supported.Using Nexus 5 with UBER Kernel after update its not supported on every kernel. Fix it

Dylon A. G. Smith

New ui please Please please please new ui.. Why do heavy duty toolkit apps never have nice ui ..its great for functionality but ui just bugs the hell out of me

Sagar Terekar

Good Good but it doesn't come with some modern UI. Looks powerful but somewhat dull. Great app though.

Micha Schellingerhout

Amazing Love it, fiddling around with all the settings. It hasnt blown up yet, thats good I guess..:)

Derek Logan

Plus hlp Json configuration parsing error sky high kernel root stock rom sm-t805w galaxy tab s

Bira Hawker

The best Simple the best, everything you need to control your kernel is here.

Yudha Piero

Nexus 5 How can i bringing back gamma profile that has been deleted by accident?

Forid Snm

Restore Restoring has issues, json has issues. What is this...

Hendry Setiawan

It is great but the profile backup/ restore feature is broken.

kaveh ensafi

Please ad more support for galaxy s5 octa core smg900H

Fredrick Estrada

Needs Repair User desired preferences are not holding making the kernels unstable during boot causing freezing while unlocking the phone immediately after boot takes up to four minutes to settle after boot before you could even unlock the phone or forces the phone to hot reboot do to unresponsiveness if attempting to unlock the device immediately after start up as well as every time you go make a backup or restore your settings files it crashes & force closes as a result the desired user back up is not restored


Please rework / optimize the Boot settions. Some users have issues , settings not hold

Alexey Andronov

Phone freezing up randomly After rooting my Galaxy Note 4, this somehow got installed (maybe bundled to rooting app, maybe part of TWRP rooting process?). I browsed it but didn't change anything on any screen. Then my phone started going unstable after ~2 days of use: waking up would take about 10 seconds, call interface would not come up in time to pick up a call. I removed apps one by one and removing this one solved the issue. So it must be the one causing the problem.


Awesome power over kernels etc. HOW do I add a special thanks t someone in the info window? I see many kernel devs have added specific people in that field in the app. I own it. Please and TY! Fas

Kevin Ireland

Settings wont lock properly When i reboot some of the settings change like for when u choose a setting it stays like that even after a boot untill we decide when we want to change them...ill give 5 stars once that happens but over all its one of the best if not the best...keep up the good work devs.

Billy Lima Castro

Like it a lot but.. The app is very awesome but please update it to material design!

Dania Yinka

Lot to be done This should hv been d best..but boost won't stick and also pls integrate tasker. Like Kernel Auditor

Christopher Booker

Gadzooks so far! Most in depth kernel settings app I've seen so far. Gonna play around with it for functionality with ur nebula kernel... Very impressed so far.

albert usher

Gets the job done I have a Sm g928t and use synapse with upintheairs kernel for my model. I follow the instructions that are laid out for me in black and white. I have great results with performance + battery life. I give synapse 9 stars out of 5

Wesley Zhao

Add a feature Add a confirmation to the optimize data bases feature under tools. I was scrolling through and accidently pressed it then the app froze for 2 minutes. Just kind of annoying

Joel Clendineng

Great app Ui is pretty bad and the app doesn't scale to bigger screens and profile restore is broke but it does what it claims and it is free so there ya go!

Shishir Timalsina

Does not work No UCI supported on sgs3 running cm 13 nightlies

prosenjit nath

Actually it comes pre installed in Archidroid Rom 3.1.5 for my s3 I must say it's awesome fully functioning with archi kernel...

Jyotirdeb Mukherjee

All settings are good but... The app is very good but if I select barry_allen governor on my nexus 6P my phone reboots. Would love to see it fixed. I think it is happening due to the 64 bit arm architecture. Would be great to fix this bug.

Ajith Chandran R

Great App To be what it supposed to be and to do what it supposed to do. Simple and great.

Indranuj Kar

Awesome The best app to manage your kernel and rom provided it supports it! S6 edge

A Google User

Astonishing idea but forgets profile!

Thomas Wall

Best app for control of my device! I've tried dozens of apps and synapse is by far my favourite. Thanks for creating this gem!

Hân Phạm

Great but I need manual I dont understand clearly of how to use this app properly. Please help! I already have Skyhigh kernel on my note 5.

Tushar Choudhary

Anyone? So I've applied a profile, but when ever I open Synapse I get a cross and a tick. I don't know what does that exactly mean.

M-Ubaid Raza

Works well, but interface and usability is very difficult compared to kernel Adiutor.

cole edwards

Great control Tons of options

Mihir Mistry

I love it !

S4-8 muthuvel vimal

Settings not sticking on boot on Marshmallow

Lee Haynes

I know it's a known issue, but... Any fix for the Qualcomm min CPU speed reverting to 300mhz? I have it set to 422 to alleviate Bluetooth music skipping on screen off. However, at random times the speed will default to the slower speed.

Akhil Jaya Sathyan

Awesome app Those who get UCI unsupported message should flash UKM. Google it. Don't give 1 star because you cannot figure out how to use the app. ? As for me, I keep coming back to it to enable Fast Charging if it's not set up by default. Color profile modification is another awesome part. Perfect companion for AK kernel.

Sapri Hardianda

Crash, edit : working good after changing theme to default At first its work fine and i can set thing up but then it suddenly crash everytime i want to run the app, My Device : Xiomi Redmi1s, running cusrom unofficial cm12.1 latest release, kernel used : xcelerate build prod 20 for cm12.1 by kairi, hope you can fix this, thanks

Dusan Knezevic

Very good - awesome Awesome app. It has some small bugs that can bother kernel/ROM developers but app dev was always listening to others issues and helping out. I recommend this app to any dev. It's simple JSON interface is like from heaven. Only kernel/ROM dev or script "magician" (like UKM) can add support for this app. Other who get UCI not supported should really see if they know how to add/enable it and not rate app lower. Those who get JSON parsing failure always have some small unnoticeable syntax error.

James Longfils

Brilliant App. Quick one:- Core Boost Freq overrides and "max active" clusters aren't preserved after reboot. Example I have an 8-core A53/A57 cluster. If I disable two cores each per cluster using "2:2". It would be great to have that preserved after reboot. Great app keep up the great work.

Chris Rodrigue

It's great but the UI needs work The X and checkmark are very annoying and clunky to apply settings and profiles. When importing profiles, not all the settings change. Awkward to use. I think updating to proper material will fix all these issues. Overall, fantastic kernel app. The profile support alone makes it highly valuable.

Cristian MARIA

No UCI support detected rooted Galaxy Alpha, it only shows a black screen and " No UCI support detected"

Afif Azzazel

Makes me look like magician What a great app, but i have to press the power button once after reboot then the app works like it should

Tonny Hermawan

It does what it says but.. But the setting is not stable.. it revert back.. the setting not stick.. try many kernel.. kernel auditor is better than this in term of stability.. term of feature and uniqe management this app the best

Mojtaba Ashti

Excelent... this app need custom kernel with Synapse features

Mike Adez

Love it Enough said

e anbarasu

Beware of this app It's powerful and it's very dangerous . because some it will freeze your phone . don't try to use with your instructions before use this app

Theos P

Fabulous job. It appears initially it takes a longer time to understand and be able to master. Most of the problems related comes from permissions related(supersu) and this app by itself is very reliable since it rarely catches in bootloop. Tested 3 days over 60 hours. Now all settings stick properly.


Great! Well built app with alot of advanced features.. don't try to mess with them alot!

Majed Kwekah

Majed Kwekah Amazing App thank you ❤

Ibnu Sena Soliqin Putra

Total Awesome Work flawlessly on my i9500 with voltaqe kernel, even saved my phone by resetting itself when my OC got too far, kudos!

Amin Khaki Moghadam

Simple And Strong Juat 1 question. How can I revert back my changes to default? I didn't find any option for that...

Blaze Frostbyte

Very detailed Lots of options. Well done for a free app. Thank you.

Salim Nazar JumboBag

Advanced User This app for advanced and experience user only so please dont give bad stars :)

Muhammad Aamir

The app has no effect anymore

Chris Levine

Best kernel manger ever Amazing, all I would recommend is material design

Shashank Kundliya

Amazing app for kernel tweaking

Shony Saputra

Settings don't stick Every time I change values they don't stick and revert to original. I have flashed many custom kernels but the results are still the same. So it's must be this app preventing my desired settings!

Peter Federighi

It was great when it worked When it worked i would have given it 5 stars. Ever since going to MM, Synapse just doesn't work correctly. The settings may or may not be changed. While it allows me to save profiles, it rarely ever allows me to load them. Apply Settings on Boot always fails. Stability Check always fails. Perhaps it still works for LP and older Android versions.

Do Think Twice.

The Best So many features. All the right controls, it's free, and developer friendly. Way more controls than other kernel manager apps

Guilherme Souza

Terrible The UI is disgusting, think about a glitched holo. Use only as last resource if no other app fill your needs.

Ionut R

It requires root although not clearly stated

Robert Wade

Happy Was the best decision in my life

Arnav Jain

Does what it says very well! For people thinking why I can't access some particular function it is because your device software or more specifically the kernel doesn't support that function, and exercise caution while using the app it may render your device unusable, it has sliders which doesn't mean you can mess around with it any way you want! Now for the app its very well made and a very useful and powerful tool if you know how to use correctly

Hari Angga

Profile Why don't you add profile feature so i can save and switch all my configuration instantly

Reg Thomas

Hardware controlled A good way to keep hardware from running at full speed and burning up battery life.

Ammar Hafiz

Some feature does not work Master switch for boot do not work,

aurey Col-Hos

Greatness hands down!!!! This can be really challenging to use of you're not advanced and familiar with you're ROM and how u want it to work, but since I understand how to use this, it works great with my custom kernel, there are so many options to chose from and so much things I can do, if u need something to help tweak down to the little end, go with this app. If anyone experiences bootloops or random crazy things happening, you shouldn't blame the app dev unless u got a logcat. Otherwise it's your own tweaks, tweak and learn!

Pete Le Boydre

For samsung tab s Nice to be able to control nearly every thing that the kernel builder has set up outstanding.....

Mostafa Rahmani

Saving impossible Profile can't be saved.
