I own the Sprint Samsung Epic 4G
Twice I have had a problem were after charging over night the phone is hot near the camera area and the phone is extremely laggy. I just power down the device and turn it back on and it works fine again. This has only happened in the span of 6 weeks. My sister has the same phone and she has not encountered this problem. Any suggestions?
Not sure if a reset will fix the problem and I wouldn't even know how to do it.
*Side not the volume will randomly drop down really low and I have to constantly raise the volume. Not a big issue but again after paying money in the amount they wanted I should have to deal with that.*
Somewhere around there is where the SOC resides I think. Would have to look at the pictures of it torn apart again to make sure. You might uninstall your apps one at a time or a few at a time - reboot and see what it does.
You might also go into settings>about phone>battery usage and see if something is using a lot of CPU cycles. Watchdog, OS Monitor, and a couple other programs will list specific apps and processes so you can tell exactly what's doing it. CPU Spy is a great tool to use too - it will show you what speeds your processor spends the most time at.
As far as the volume, you may inadvertently be turning it down. If not, you might root your phone (if you haven't done it yet) and slap on the stock EK02 rom, kernel, and modem. If that doesn't solve the issue then go back to stock EG30 - unrooted of course (sticky thread in the development section for this phone) and return it to the store. It might be a hardware issue.
Ever since I updated my phone to stock 4.0.4, it's not been the same buttery smooth Epic Touch that it used to be on Gingerbread. Sometimes the lags gets so bad that the phone would restart itself. I have done a reformat and things have been going smooth for about 2 months and it has started lagging again now. Right now I am running minimum 3rd party apps, and only limited to reputable ones such as Facebook and whatnot. The CPU Spy shows the phone is in deep sleep most of the time. Android OS still takes up about 90% of battery usage. I made sure nothing is hogging up the ram in task manager and clear memory 2-3 times a day. Yet, it still lags like crazy especially while typing or turning the screen off.
Can anyone chime in on what else could be causing this?

since you mention facebook what's your sync situation like? just a suggestion as I remember similar threads where constant syncing was causing issues... if android os is using that much battery something is amiss... its just a matter of figuring out what...

FB's refresh interval is set to 1 hour. Is that what you are referring to?

Welcome to ics. I get the same thing and have tried everything. Good news is they are pumping out new builds pretty quick to hopefully they are working out all the kinks.
Sent from my SPH-D710 using xda app-developers app
try a different rom.
What causes the occasional lag on the Nexus 7? With its fast cpu and ram it still seems to have more episodes of lag than I would expect.
Is Is there a utility that would let the user see which app or background process is responsible for the overloading? Some apps may not be worth having if they overload Android.
Or, since lag occurs after using the tablet for a while, is overheating the problem?
Something else?
Trying to understand. Thanks.
It's always hard to pinpoint what causes lag. You could run low on available ram then when something needs it, the system cleans up some older stuff, causing a delay in the action requested. It could happen while waiting for a minimum CPU freq to get to a smoother one. It can also depend on how the selected governor/scheduler are handling things. That's just to name a few.

From last few months, I've been noticing a major slow down in my device. It lags a lot freezes while opening almost any app making the phone almost unusable for daily basis. I don't know what's causing the slow down.
Here's what I've already tried with no positive results:
- Completely formatting SD card + Internal storage and Flashing stock ROM
- Completely formatting SD card + Internal storage and Flashing CM ROM with all android versions (4.1, 4.2, 4.3, 4.4, 5.0, 6.0)
- Frequently cleaning cache partition and wiping all application's cache.
I also have very few apps installed on my phone and there are no major load on the RAM as well.
I am wondering what can cause such slow down?
As far as I remember, this device wasn't that much slower when I first got it about 2 years back.
Does Google services are causing incompatibility with this device causing freezes or this is a hardware issue? (If it is, then which part of hardware could it be?).
Also do you also experience such slow downs, lags and freezing?
You can try to change your kernel and modify a few things. I really suggest using Wild Kernel and downloading the Trickster MOD app on Playstore and change your settings. I usually set my Governor to "ondemand" and it's worked pretty well. I used to have this problem too back when I had the phone on "batterysaver" and it was a mess.
I agree with the kernel tweaks. I"ve noticed that this device does NOT like to go below about 250mb free ram. I've set my LMK settings very aggressively. Accept for foreground applications, I've set everything to 3x normal.
I too am using On demand, tweaked.
I/O set to BFQ
I also like to run Chainfire's Recently (check the playstore) and I set it to max 6 apps with a limit of 6 hours. I only allow 2 Google search instances, no settings screens and I set it to remove each apps documents as well.
With the above, I experience very few slowdowns any more. I should add, that I am using MM roms.
Hi All,
Anybody here with the same issue ?
Looks like a software issue/touch unresponsive issue because usually I find it coming back to normal once I press power button and unlock it again.
Sounds like RAM allocation issue, isn't ?
Thinking to sell it. Please suggest if you guys know a better way to deal with it !
Even if I go to SC, I cannot reproduce the issue at that particular time. They will just reset it and give me back, and that where I don't want to waste my time.
Does this looks fruitful to flash stock firmware again by the unbrick way ? I feel like that will be me last try.
You seem new here, so welcome on xda
One thing you should keep in mind is to be as precise as possible when presenting an issue, your description right now is not very clear, by the title it sounded like your phone actually froze, which could have been a ram or even a power management issue, but after reading your post it seems more likely that your display was wet, or that you were charging your phone, capacitive touchscreens are sensible to that.
Usually a frozen phone does not respond to the power button like yours did, and a ram issue seems very unlikely tbh

My style of using I believe is the same and I had no such issues in my Cool 1 ever in an year. Was a lot better in every way. Picked it up because I loved the looks, but have lost my trust on Huawei. They really need a lot of improvement.
i am having the same issues as the OP (Although i don't know what he means by "going to the SC")
the phone just goes through moments of extreme lag for about 10-30 seconds, sometimes longer, and it makes the phone COMPLETELY unusable during those times. it happens at least once every other day or so, sometimes several times a day, and sometimes it only lasts about 10 seconds, although on a few occasions, it has lasted several minutes, the phone will "attempt" to respond to inputs, but it gets nowhere quick, opening apps i did not click on, closing apps that weren't open, black-screening, half-screening (app on half the screen), etc.. sometimes i have to just power cycle..
i have the exact same feeling as the OP in that i want to sell the phone. (although i type much better, i'll assume english is a second language for him/her)
i like EMUI a lot.. although i think i want a galaxy s8/s9 now.

Since yours is the us variant, I'm assuming you've got 3 gb of ram instead of 4 gb, in which case a ram issue seems much more likely.
Not much of an issue actually, just that you probably had lots of apps open at the same time, leading to almost full ram (so the system starts closing background and even foreground apps if needed, leading to the strange behaviour you noticed).
Just remember to close apps you don't use and you'll be fine

It's 2018 and I think the OP and I know how smartphones work. I am coming from a phone with 2GB RAM and it has no such issues, no matter how many apps and/or games are open. Google explicitly states that closing background apps is unnecessary, and I should think EMUI offers an improvement over stock Android, not a detrimental experience. However, if you are correct and it is the RAM, it is not acceptable and needs to be fixed or I'm buying a new phone from a different company. In today's world, phones will open links to Chrome and from Chrome open reddit, xda app, pinterest, link to Facebook, share to Twitter, etc etc.. every time I click on a button I should not be having to back track to make sure I only have a certain amount of apps open. Nougat limits max open apps to 20 BTW, marshmallow it was 30.. But RAM management CPU management should be better. If it's of any interest, my reported "free" ram always stays at or above 1-1.5GB so I don't think its ram.. CPU or software problem, possibly.. But my Temps are good as well. Yes it's the 3GB version
Just a quick thought of something you could check (I also have the US 3GB version and was experiencing the same issue). Open up Settings > Battery, and other the "Other" section click "Consumption". See if there's any apps there that are keeping the phone awake and preventing it from sleeping. I would get constant lag after only a few hours of use, and it was intermittent just like you're experiencing. I was about to send the phone back, but checked this setting first. Turns out, the CNN app was running the CPU at nearly 100% for hours on end and preventing the phone from deep sleeping. Once I uninstalled that app, I haven't had issues since then. Could be something similar, just a thought. YMMV.
And by the way, it's NOT the ram. 3GB is plenty. You can see how much is being used on the app select screen, and I've never used more than 1.5 with a ton of apps in the background.
Let me help you there guys....i got the US variant too and has these freezing and lags all over the place, what i discover and did was:
1- Not all the apps works well with the phone hardware(they told me that somewhere) so try to test the apps you put on the phone.
2-Delete all the unnecessary apps from emui, that will give you less lag.
3-Check the battery consuming apps like the guy said and if you want turn on the close apps on screen lock.
Now after all of these my phone have been moving better but the problem isnt the ram, is the software so wait a little more so they can fix this cause is really a good value phone
It has to be the RAM management. Huawei must have optimized the software for 4GB, and then released a US 3GB version without changing anything, so it's screwed up even though phone is showing lots of free RAM.
Wao man thats the best explanation for this problem thanks man
It isn't and never was a RAM thing. Android's memory management essentially force closes apps (but shows them in recents) if it needs more memory. Note there is no work involved in that and you'd never know it until you switch apps and it has to reload, shows logo, etc. Amazing how non-solutions we're brought up multiple times and even thanked. Insert that's-not-how-any-of-this-works meme.

Well, yeah, ram issues nowadays should not be present, but I do speak on a basis, I have experienced bad performance and foreground apps getting killed on a nexus 5, which has 2 gb of ram and stock android. I have no idea what's emui's ram management policy, but on a scale, this would be the least likely cause for sure
