Hi guys,
I've had my HTC One for over a year now and love it except recently it seems to have gone really slow / sluggish and visibly takes ages to do anything recently. For instance today in work I wanted to show someone a photo I took on my camera this morning... I went into the camera app and then clicked the thumbnail at the bottom to get to gallery and it must have taken 30 seconds to open the picture.... as much as I have iPhones, with them I have seen people click and it is pretty much instant....
I have updated it to the latest software (4.4.2) as soon as it was available a few months back and it is completely stock / unrooted etc.
Is there any way to either a) find out what is making it slow or b) get something to make it faster?
To note, I would rather not root / install a custom rom if I don't have to but if thats the only way then please do say so.
Thanks in advance for any help.
Did you install any new Apps that might be hogging resources?
There are process loggers and probably take a look at battery drain to identify apps.
I'd suggest to backup essential information (just in case) and perform a factory reset.
Thanks for the responses guys:
@gotcha69 - I install apps all of the time so it may well be this but I have no idea how to track down which one is at fault, shy of a very long process of installing everything one by one...
@davebugyi - can you recommend a process logger please? Looking at battery app usage this morning, 41% Google Play Services, 40% Android System, 5% MX Player and TV Catchup 2%... does any of that seem unusual?
Was watching a video on the way to work this morning and when I got there, pressed pause and it took a couple of seconds to actually stop the playback. I just cant get my head around a phone more powerful than most desktop/laptop computers from 3 years ago can be so sluggish for simple actions.
Definitely thinking about a factory reset - is there any way to backup apps on a non-rooted phone?
@gk141054 - I use only the built-in app in Android Tuner, but you can try OS Monitor or Elixir 2 or CPU Monitor.
For me GP services a bit too much in my opinion.
To back-up things you can use the accounts sync option on a non rooted device - copy all your stuff into a computer from SD Card, but nothing much can be done with apps. Maybe you can try HTC's backup app (can't help much, since I am rooted and using Titanium backup).
Check your media server

I've been having a bunch of trouble recently on my HTC One... some app update (I suspect Twitter for various reasons) has been causing my HTC's media scanner to go crazy, frequently hogging 25% CPU and causing 15% logcat (as measured by CPU Monitor).
I finally solved the problem seemingly by force closing the media server, clearing its data, force stop twitter, clear its cache, and delete it's cache folder (Android/data/...twitter/cache). For good measure, I also cleared .thumbnails (DCIM/.thumbnails, use ES file manager and enable hidden files).
Your mileage may vary...

I had definitely the same issues with my HTC One M7. I identified Mediaserver as the source of the problem. Mediaserver regularly scans all files on the device.
What I did to get rid of the problem is installing SD Maid (Pro) (no rooted device needed!). Scanning and deleting all the trash files that accumulated in the last 2 years freed about 2 GB of space!
Since then no lag on my HTC One was encountered!

In my new Moto G Indian dual sim bversion Asphalt 8 is sometimes crashing suddenly without any error message like 'Unfortunately Asphalt 8 stopped' etc. It's directly comes to the homescreen quitting the game all of a sudden... Is there any problem with the game or firmwire? I downloaded directly from PlayStore. Any same incident or help?
Did you try reinstalling it?

try freeing some space & clear cache
I did it.. Cleared cache and data too several times. Even did fresh reinstall from PlayStore. Same problem occurring again. Even sometimes just before the end of a race and coming 1st position game suddenly crashed. Total frustration! Space available a lot already!

I've just got a moto g (1 gen) LTE model running 4.4.4... from amazon in the UK. I thought I'd try Asphault 8 to test out the phone today. Crashes back to the homescreen with no message whatsoever from the menus, during loading and sometimes I can get it to just get into the game.. when I use task manager to got back into the game it just loads from the start again (Gameloft logo). I haven't actually been able to get through the tutorial at all. Medium (default) settings.
Any ideas?
i think ram management problem in the new moto g 2nd gen... I never have this problem on moto g(2013)
same
same problem tried it several times always crashes no matter what u do
same problem here is due to low ram clear ram before playing game.
Asphalt 8 not working for me too..
The same happening to me too..
you are right---"i think ram management problem in the new moto g 2nd gen"
This happens with the background apps also.. closes for no reason...
Yeah the problem exists.
Asphalt 8 does crash to main screen and many apps are closed in the background. Can someone tell what issue is that and how can that be handalled. Also Firefox and Chrome don't keep the tabs loaded in the background. The tabs reload even if you jump from tab to tab, which is very bad and inconvenient. If someone finds a solution please tell, waiting for reply.
All this problem have only 1 reason low ram problem try to free up ram before playing any game u always disable apps that you dont use like some motorola app to free up ram.
Clearing RAM is not a proper solution. It crashes even after that. In KK ram is cleared a=by automatic in built tasker. Anyway, after a much research and tinkling with my Moto G2 I finally came with a successful solution. Most of the time with high graphic most part like Dubai track with high speed car the chance of crashing suddenly is more. Moto G 2 has a serious RAM management problem. Hope this bug may be corrected in L update very soon. With smaller application it is not felt particularly.
Anyway, root your phone first. Install RAM manager (paid app) and any build.prop editor. First edit your build.prop section the VM Heap size to 512 mb and VM Heap growth limit 256 mb. No matter, due to less collection of paging garbage your battery backup should also increase a little. But your RAM potential will be utilised at fullest. Now go to ram manager set 'Hard Multitasking Mode' and clear memory with it before playing the game. Asphalt 8 will never crash!! Tested!!

I changed only build.prop as you write on my Moto G LTE (1 gen.) and now Asphalt 8 works fine. No more force close. Thanks!
I had this problems with asphslt 8 and other big games... I wont root until 5.0, but I hope motorola release an ota to fix thid ram bug...My 1st gen Moto G didnt have this bug
Same Problem.. But is Rooting the only solution
I am facing the same problem as GT racing 2 also force closes. and Real Racing 3 too tried several apps but i'm unable to run all the apps. what to do
asphalt 8 :airborne
I have installed Asphalt 8: Airborne on my XT1068 , and it runs smoothly with good graphics ( i didn't change any settings for graphics in the game )
the game crashed 2 times after installing , but it has worked fine ever since i rebooted the device once
my device is rooted but there is no optimization apps .
Real racing 3 also worked fine without a single crashed, since i haven't installed many apps there is always about 300mb RAm free
Asphalt 8 crash on Moto G2
I'm facing the exact same problem on my Moto G 2nd Gen. What do I do? I really want to play this game.
My gf's Moto X (1st gen, stock, unrooted, Verizon, 4.4.4) has been freaking out lately and she brought it to me to investigate. The thing will sporadically tie up all of its RAM and basically become unusable. Phone gets hot and battery drains fast.
I understand how Android handles memory, so this isnt me being paranoid about available RAM...im talking about less than 20mb of available RAM and I cant even open the app drawer because it crashes. I clear all recent apps, force close anything i can, and no RAM opens up at all. Only solution is reboot and then its only good for a few hours until it gets jammed up again.
Sounds like a software issue to me, so a factory reset should fix it, but i just dont want to deal with backing up my gf's crap and heaven forbid i miss something and lose it forever. Anyone have any ideas?
PS - gsam battery monitor shows nothing noteworthy...doesnt report weird app usage, and no wakelocks or anything like that seems out of the ordinary.

Something like Watchdog Task Manager or a memory monitor app might help you figure out what's misbehaving. Logcat might give some clues.
Personally, I think I would just prefer to backup what is necessary and reset the device. You might spend a lot of time trying to attack this from any other direction. Good luck.
I'm really new at this and it looks like nobody care about each other. When someone asks for help most of times gets no answer at all... at least with me. I've asked for help in a lot of sites but nobody replied me. So my last hope is here.
I tried everything to solve my Moto G 2014 lag issue. Changed ROM, Kernel, Kernel APP (Synapse,Kernel Adiutor, Device Manager etc) , flashed the MK_PFRMCe v3.0 , I even FACTORY RESETED. My RAM looks fine even with a lot of apps open (usually I have 150MB left) so the problem is the massive lag from nowhere! When I open the sms or whatsapp everything starts to freeze! I've downloaded Watchdog Task Manager in order to find any problematic apps but still... nothing was found.
I've tried to search good performance tweaks of kernels but I couldn't find a recent one. So I tried to search here but i couldn't find any guide ANYONE HELP ME PLS!!?
Not really much to go on, but it could be a sign of a falling eMMC.

Im in the same boat here. Had original 4.5" Moto G & loved it for a couple of years. Upgraded to the 2014 (XT1072) model for the bigger screen & have had nothing but trouble with it.
Upgraded in April, was OK for around a month but then huge lag problems started. SMS app takes forever to open, Chrome is very vey slow to do anything. I get phone calls & miss the call due to the inordinate amount of time it takes for the screen to illuminate. When I make an outgoing call, I hear at least three or four "rings" before I get the visual "calling" thing on the screen.
I;ve tried clearing cache which makes a slight difference for a week or so but then it goes back to being unusable. I;ve also tried factory reset which sorts it out for a few weeks.
Very disappointed with this MotoG. So much so I'm considering switching to an iPhone 6 on a monthy contract.
I have a N6 purchased Dec 2015 new from Amazon. The only mods, if you can call it that is, I have unlocked the boot loader. I am currently running N6F26Y sideloaded via ADB.
The phone was great when I first got it but now after about a day or so of usage it becomes slow and sluggish and unresponsive I have to restart it to use it. I have done a factory reset a couple of times which gets it back to normal for a week or so and then the problem recurs. Occasionally I will delete the cache which also helps. Snapchat is one of the worse apps - crashes the phone regularly and is a very slow app.
Also the camera can get very slow often taking seconds to take one photo.
I love the phone but it's becoming unusable now. The contrast between this and a new phone (I have purchased a Moto Z) is like night and day. The Moto Z runs instantly, has no lag and is a nice phone. But what I like about the N6 is the large screen which makes it great for videos etc.
Short of perhaps flashing some custom ROM is there anything I could be doing?
I'd recommend flashing a rom like pure nexus, super stable that should fix your problem, otherwise you've done all you can and is the easiest fix

Hello,
It seems like some apps are really slowing down your phone. I use my N6 at home for web browsing mostly as I have a Pixel XL now. Just like you I love the screen size.
The camera has always been slow fore, because of the time it takes to focus...
Did you try using your phone a few days without Snapchat installed? Maybe you also have other misbehaving​ apps installed.
Uninstall Snapchat and other apps and start from here. Reinstall one per one with a few days interval. See if the issue still occurs.
Installing a custom ROM + kernel will likely speed up things a little bit. I second @Dugaldrob with Pure Nexus and I'd suggest ElementalX kernel on top. Running this combo on N6, N6P and Pixel XL and they work flawlessly.
I don't believe installing a custom ROM alone will fix your issue though. Stock ROM shouldn't cause the phone to slow down to the point you need to reboot to use it.
Finding the culprit will...
Good luck...

First step is to remove Snapchat. I rarely use the app and only because my daughter sends stuff on it. I am going to tell her to send me stuff via another method
If that doesn't work then it's a new ROM. I have performed ROM installs before but have never flashed a new kernel on a phone before so that will be a new experience. Hopefully I won't brick the phone

I've been running Pure Nexus and wanted to let peeps know I put Nitrogen on and man it's so smooth, my wifi tether is back and I went to sleep last night with 50% battery still. When I installed it I opted for the nano gapps I think so like 175mb for minimal apps and maybe that's why it's running so efficient. Maybe I could have re-installed Pure Nexus with a clean install and it would have gotten better but it was a good time to try something else. Also when Nitrogen got an update I was notified just like stock and it downloaded. I didn't even know these could do that. Anyways give it a try and you might just switch back. I was looking into new phones but if it keeps working so smooth with battery longer than a day then I'm fine for now.
Snap chat is not that big of an issue. What I have found to cause the device to slow down is normally almost full device storage and a crappy cache release code in apps. Some apps don't release their cache properly. So it causes lag. This is why a reboot seems to fix it.
While a custom rom may fix this issue it is not the solution. The proper solution is to find what is causing it and fix/repair/ditch it.
Worst offenders for crappy code in my thoughts. Other will disagree with one on this list I am sure. So don't bother. I know people swear by it. It runs like crap for me at times and causes my whole device to lag until I close it out.
1 Facebook
2 FB messenger
3 Google Chrome ( don't do it lol)
4 whatsapp
5 Hangouts
Mind you this is just a list on my usage. It may very per user and even device (considering different hardware)

I can confirm this, because I've removed these apps (-whatsapp) and also decrypted the data partition...
My N6 is fast.
Maybe a lite stock ROM and an other kernel is a good start.

Currently I have FB, FB messenger, and Chrome but when I installed gapps I chose a super lite install so tons of bloat and google apps were not installed and my battery has gone way up and it's so smooth. I'm sure even when we don't use apps they're always doing something in the background. I bet you're right and a stock lite ROM would be good too with the minimal bs apps.

Thanks for the advice. Of the list of apps above I have only Chrome and Hangouts. I really can't see replacing either of them.
I also should have pointed out that the phone locks up randomly requiring a hard reset. I wonder if an errant app could cause that or I have some RAM problem. Certainly on a PC bad RAM can use in Windows a blue screen or something but perhaps Android isn't so forgiving?

I would flash TWRP, flash supersu in TWRP to root, make a complete backup in twrp, then remove whatever Google apps you're not using with a system app removal app. Getting some of that bloat off the device should help. If it's still laggy, then look into a custom ROM. I run Tesla on my Nexus 6 with none of the issues you're having. I don't decrypt it either
Running abdroid 7.1 here. I dont get any slowdowns, at leas until the battery doesnt drop below 50 and 25 percent.
Im running a custom kernel and my phone is rooted. Everything else is stock.
Can you flash a custom kernel and presumably TWRP without wiping the phone? If so then might try that before a custom ROM

Hello,
Since your bootloader is unlocked, flash TWRP and install the kernel, no problem.
Might give you a slight boost at first sight, but your device will likely slow down over time anyway...
Cheers...
I'm on 7.0 with the April SP. I have dozens of apps installed, including Hangouts. I use Firefox for browsing, I like it better than chrome (and you can install an ad blocker).
My camera slows down when the battery is under 40%, and the whole device slows dramatically, though not unusable, at or below 5%. But otherwise, no issues what so ever.
One solution that I have not seen suggested here is resetting the device and NOT taking the Google account backup of all your apps. I would suggest making a completely clean install of the factory rom you have and installing one or two apps at a time, most important to you first. And do this for a few days/weeks until you find the app that's misbehaving.
Although there are general bad players out there, this bad app could be unique to your device. Just because all devices of the same model have the same specs and components, doesn't mean that there isn't variability in parts quality.
I would do this before trying any new roms or kernels. Find the true problem first.
Good luck!
edit:
I had another idea: Go into your battery stats and network stats and storage stats and see if any app seems to be using too much of any, or all of the 3. This may get you the answer more quickly.
