Wake Lock - PowerManager

Basically I tried everything in my power to fix my note 4 for about a year...but in vain. Freezes, gets into an endless 'could not do normal boot, mmc_read failed' error mode, fires up again, giving me false hope and crashes again, etc. Total madness. I even bought a brand new spare battery thinking that would save my phone, but nada! It's a shame that Samsung is getting away with this. My phone was absolutely healthy until they pushed the security updates of Sep. 2017. Now thanks to this app and it's developper, been two months already my note 4 is back up and running. I don't even know whatever this app is doing to the system board but it's holding it alive and shining again. Huge thanks!

My phone was acting weird. It was freezing all the time and restarting itself often. I tried to factory restart, I tried to delete the cache partition and I tried bunch of tricks to solve the problem. None of them worked. Then I saw someone recomending this app. At first, I was skeptical and as far as my understanding goes this app should even make it worse by using some of the cpu all the time. However, somehow this app makes it work and solved my freezing and rebooting problems. Thank you :)

I used to use this on my note 4 and it was great then but i didnt think it help my ROG phone 2. My issue was the phone was rebooting WHILE using it so i thought no way this would fix it. But somehow, magically, since installed this no reboots in the last 4 days! Its really amazing. This should just come stock with phones, truly.

I was highly skeptical, but my Samsung Galaxy Note4 went from being close to totally unusable to seem almost like it should behave. It seems this program takes over the role of power manager for the phone, as the behaviour indicate it prevents apps from locking resources causing glitches and crashes. No idea why this happens with the original software which worked fine up to a month ago. Changing to new original samsung battery only had a 10% improvement on stability. This app fixed the other 99

I have no idea what this app is doing but it works. It prevents my Galaxy Note 4 phone from freezing and from the “could not do normal boot, mmc_read failed” error. That being said, most Note 4 users probably have a spare battery, and the process of switching battery still have some freezing issues. However, I found a get around solution by removing the battery, wait 5 minutes, put the recharged battery in, and wait another 5 minutes before power the phone on. Thanks for saving my Note 4. Oh, and don't just thank the app developer, send him/her a well deserved donation.

Works well. It's currently the only thing making my galaxy note4 usable. It uses some battery but it stops it from crashing every time I unlock the phone by not letting it hibernate in the first place. Thanks for fixing an issue that Samsung couldn't be bothered with.

Phone would not get past network carrier screen before getting hot by on/off button and switching off needing a reboot. Would sometimes get further but then either freeze or shut off completely. Managed to get phone working long enough to download this app. Issue resolved immediately. ..

Just when I thought my Note4 reached the end of its life, this app which I came across on youtube saved it from ending up in the trash. Saved me from having to spend hundreds on a new phone. I was having lag, random reboots etc out of nowhere, not anymore. Thanks!!!

Literally just download it, of course it crashed 3 times while trying to download, so i plugged the charger in even, tho the batt was at 50%, crashed one more time on the charger then finally stayed on long enough to download. I selected "partial" and now im off charger at 41% charge and NO CRASHING! It was literally crashing every 2 minutes before i googled this fix! i was actually shopping for a new phone yesterday! Love the removable batt on Note 4!

I downloaded this app about a year ago after buying a new galaxy note 4. My previous one mysteriously started acting up after an update and then bricked itself. Before I installed I was getting the same problems on the brand new phone: fresszing, black screens, random restarts etc. But since I downloaded this app NOT A SINGLE PROBLEM! this app is truly a lifesaver. Thank you developers

This app saved my galaxy note 4. The phone was barely a month old and started having problems with automatic restarts ( 10 -15 times everyday). I searched for solutions on YouTube and almost everyone recommended this app. it works great. I have not had any issue since i downloaded this app

As others have said, this app saved my Galaxy Note 4! Thank you SO much for this, pizza sent! :) One request - would it be possible to have an option to prevent the Wakelock notification showing up on the homescreen and notifications? Just having the icon in the task bar would be great. Anyway, thanks again!

Yes! Best app ever! Now I never have to worry about my VPN connection dropping when I hit the power button to turn off my screen. I've been looking EVERYWHERE for this app. Thank you so much to the developer! 10 stars!!!!!

This is s very useful app. I recommend it highly as a simple tool to keep your screen on, or just to keep your phone from going to sleep on you.

I guess this app is especially designed for samsung galaxy note 4 duos because the phone creates a lot issues like autmatic restart if the battery is fully charged the phone gets down sudden shrink of battery but this app solves them all. Thank to all the developers

Wow! It works for my Samsung Galaxy Note 4, instantly when i installed the App, It's real amazing App, but also it works to my wife phone which is I phone 6 , she had the same problem of Stucking and freezing, but now things are on air Thank you Darken for this wonderful App, small size about only 30kb

this app can save note 4 and note edge but if some how your phone turn off just remove the battery and put the phone in freezer for almost 5minute then put battery back on and turn on your phone very easily

Well-made app. A massive thank you to the developers for not making this app a slow-ad overloaded app and one that works and works well. Cannot thank you enough for your work, saved my Note 4.

This may really saves my life,I frustated about my phone.Its restarting by itself,when first i thought it was a battrey issue,but not.So,i think very very far,maybe coz im playin games so the phone gets really hot.But,when im not playing games (Normal use.Instagram,facebook,etc.) Its restarting too.So,idk what to do.Hope this will works well on my device.Samsung Galaxy Note 4 SM-N910G

Why does a power manager app upload approximately 69 MB of data to who knows where? The power management features work well, though. It stopped my S5 from random reboots and freezes, for a while.

It is must required app for galaxy note 4. Reboot, slow, touch unresponsive all issue gone. It uses 10% battery in 24 hours but saved my note 4. Thank you.

After an android update, my samsung note 4 is unable to wake up after sleep mode. This app fixed the problem. Saved me from buying new phone

brilliant solved the problem of my note 4 re-booting all the time. got the problem solved . found a guy on Uribe who suggested it.. thinks if wax the last system update by samsung

So far so good,my phone used to freeze in an hour it could freeze about 10 times or so,but now all that is gone, thanks to the developers of this app

Thank you for providing life support for my poor note 4. I'm not sure how much longer I will have it considering the board is failing, but it's keeping it alive.

very useful on samsung note 4 with restarting and freezing issue.I recommend this app to all note 4 users. Thanks Developer for making my phone function as a phone again.

My NOTE 4 was falling into a deep slumber from which it wouldn't wake. Wake Lock helped stop that. Thanks!

Seems to work. Not sure which option to check off though. Going to try out the revamped version (v3) instead now.
