Do applications cause phone slow down? - Android Q&A, Help & Troubleshooting

Hello,
I have found that over time, Android phones usually get slower. Even if I delete my downloaded applications and downloaded music or picture files, it seems that the phone just isn't the same speed as it was fresh from a clean wipe. I'm not sure if this is a totally made up thing in my head, but does downloading and deleting stuff on the phone leave residual stuff that slows down the phone?

Phone incredibly slow now

Hey all - not sure if this is the right place for this post but I'm having some serious issues with my phone. I have DCD's 3.2.0 rom and r 3.42.02 . All has been well for some months now..haven't changed or installed a thing. No matter how many resets I do after a few minutes, my phone starts hanging/locking up. It's odd..it'll work fine for texting etc, but then when I go to the phone function and say want to scroll through call history, it just hangs and takes forever..soft reset makes it fine for a few mins then it slows again...any ideas!?
How much free space does your phone have right now? Try and move any extra files, photos, media onto your storage card. Have you tried deleting all your temp files and clearing out your browser history etc. Try not to have a very loaded today screen. Those can slow your phones down considerably. Also make sure you close (tap and hold x on most WM phones) all programs when not running them.
It sounds like the call log database is slowing down your device. You can back up the various WinMo databases with dotFred's PIM Backup then erase them from your phone. You might find it faster.

[Q] Vibrant very slow and disappearing apps

I am very new to this, but I have rooted Vibrant. Everything has been working fine for the most part, things have been going downhill. All day today it's just been extremely slow and when I take pics they either show up in the gallery with a long delay or not at all, I can find them in the files directory. Also, my emails were not being received nor could I send any. After uninstalling a few un-needed apps (I had over 11 GB of memory left to begin with and an empty SD), clearing cache, etc, I decided to just factory reset. I couldn't find anything that could possibly be clogging up my phone. I did, and it got a little better. I am getting my emails now, however, I tried to redownload some of my apps, and I've had major problems. Some of them downloaded completely and then just disappeared. Some of them downloaded and worked, but it took a couple of hours to download a few apps. I have no idea what to do at this point, any advice would be very much appreciated.

copied files to sd card and phone apps are hanging

Hi folks,
has any of you seen this?
I have the atrix 4g, I have a 16GB sd card, I copied some files (like 2GB in mp3) to the sd card, I safely removed the device from my computer, then from the atrix status bar I changed the usb mode to none and it mounted the card just fine, but now when I try to open apps like gallery, music player, files, or even winamp, they will just hang and I have to force close application.
Also, it drying out the battery very quickly, is like is hanging in trying to read the files.
What can I do? I don't want to have to reset the phone.
Any ideas?
Hi, ok I found the process taking all the cpu, is android.process.media, I dont know what is trying to do, how can I tell why is hanging?
I cant stop it either, is it important?
Thanks

I've had this problem twice. I think that the Atrix's software cant handle so much new media at one time. The first time it happened I ended up preforming a factory reset, which fixed everything (Make sure to back up first!) The second time was when I was adding lots of music again, and since I'm doing this constantly, I ended up unlocking and flashing to CM7.
hmmm yes this ain't my first time with this problem either and i had to reset as well. but that's too much work, i have a mod for the lapdock and having to reinstall is a real pain. but anyway I've manage to kill the media process with the kill -9 command using the terminal emulator as root and t this released everything else, gallery and music are working fine. i still don't know what will affect if i don't let the process start again, i might look for an app that would help me prevent it from starting , but if it causes any pain i will try maybe another flash like you said .
thanks
ok, I might have found another solution, may be too prompt but wanted to share.
I kept searching on google and found more options, since killing the media process wasnt very useful, eventually it would start again and hang everything. Basically, go to Settings, Applications, manage applications, all, tab on media storage and then Clear Data, go back tab media share and clear data, then reboot the phone.
After reboot the media process will start again and will scan all drives, I can see it taking something between 20 and 40%, the common at 25%, is way below the 60% that it was using before, so I gave it a second chance and let it running for a while.
Indeed, after some minutes it finished the rescan and cpu went back to 0% on the media process and I was able to open gallery, music, etc.
So, I kept all my files in the sd card, didnt have to factiry reset and the media process went back to normal.
Hope this is permanent, and hope it works to anyone else with the same.
cheers

[Q] Mediascannerservice; in the name of all that is holy, why won't you die?

I have just received a lenovo P780. I ordered it from etotalk. They pre-installed the etotalk rom. As far as I can tell it is simply the factory rom, set to english with supersu installed.
The device has a battery life that is not as good as a 4Ah battery should be. I installed 'wakelock detector'. It turns out 'mediascannerservice' runs all the time. The device never goes into sleep mode.
I have read everything I can about solving this problem. Everything I have read implies it is an issue with a corrupted media file. The thing is, there are no media files on this device. There is no SD card in it.
Things I have tried:
-Resetting to factory image.
-Deleting ALL the media files I could find (inbuilt ringtones etc).
-Resetting to factory image and uninstalling everything I could, clearing all caches and deleting all media files.
-Resetting to factory image and uninstalling everything I could, clearing all caches, deleting all media files and wiping the internal storage.
None of this does anything. This POS mediascanning service will not stop. WTF do I have do to find WTF is going on. Is there some kind log I can look at that will tell me wtf is wrong with this POS 'mediascannerservice'?
My rom has this inbuilt, but did you try with Greenify?
So in the entirety of xda developer, no one knows wtf mediascannerservice is doing or indeed how to stop it?
igasil case
So after much floundering and gnashing of teeth I have finally tracked it down to something to do with drmprovider.apk and downloadmanager.
Simply clearing the cache of these programs stops media scanner in its tracks. WTF.
Unfortunately I have to clear the cache on every boot.
In other breaking news, it would seem Lenovo phones are full of spyware. If you run a program like interceptop-ng and watch network activity you will see some really dodgy ****.
If you use any of the built in lenovo stuff, i.e. dialer, contacts or lenovo power manager you will see they make HTTP connections to some remote server. If you look at the data you will see it contains your phone number, IMEI and location. **** you very much lenovo.

Virus On My Samsung S5 Has Practically Completely Erased My SD Card. Now What?

Hi everyone!
So the inevitable has happened- a viruses infected my phone that my boyfriend soley uses. I knew viruses existed on Android but I didn't know to what extent.
The phone is a Samsung S5. It is NOT rooted.
My boyfriend was watching 'adult' videos and he has his phone set so you can hold your finger over the screen and not actually touch it to select things (IMO i think that feature is stupid! ). Anyway, While watching a video his finger hovered over one of the banner/block videos that are along the side of the actual video you are watching for too long he guessing and inadvertently selected something. He doesn't recall actually seeing anything download though.
Unfortunately because he likes to download some programs that require you to select in your settings to allow downloads from untrusted sources, he just always leaves that option selected. (Not smart).
He took screen shots of what happened next. I've included the screenshots he took in this post.
At this point his phone was frozen on the screens that popped up. He tried turning it off and on again but once back on the screens were still there and were stopping stopping him from doing anything on his phone. He didn't know what was going on and called me at work. Immediately I knew he had infected his phone, a similar type of virus was huge a few years for computers.
I didn't really know what to do so I suggested doing a factory reset. I figured he must have inadvertently downloaded something, and factory reset would get rid of everything.
When I came home from work he told me he did the factory reset like I said and the pop up screens that were preventing use of the phone were gone but he still thought he had a virus because his contacts were all messed up, they were very old and none of his newer contacts exsited (Im not sure where he got the backed up contacts that he did manage to get back...although they are mostly useless.). As well there are a lot of things missing, over 2000 pictures on the SD card have disappeared along with movies, documents, music etc... Almost 32gb of stuff!
I plugged the SD card into my computer thinking maybe his phone just wasn't reading it properly because the phone did show the SD card and you could view what was on it, but almost everything was missing.
All of the photos/videos were backed to his Google photos and they are all gone! The only thing there now is what is left still on his SD card. Checked Google photos trash and it says nothing was deleted.
His SD card is 32gb and use to be almost full, but now it has 27gb free!!!! Where did almost 27gb of data go!!?? And the approx 5gb of data left is just random stuff that I highly doubt would use up even close to 5gb...
(I just learned while typing this, that he was able to get most of his pictures back from Facebook, so nothing was removed from Facebooks backup)
I researched this for hours and I'm pretty sure this is a type of malicious Ransomeware Virus.
I think the virus is gone due to factory reset... Could I be wrong?
As for the missing stuff, my guess is either the missing data has actually been removed by the virus OR its still on the SD card but encrypted by the virus. (Which means it'd also be compacted?)
If it's still there but encrypted how can I find the encrypted files and unencrypted them.
Thanks for reading! Hopefully one of you will have an answer.
Cheers, Rebecca
This looks like the standard ransomware. I would look to see if there is one out there for android. I'm not sure there is a true version. What I mean by this is it locks out your bootloader. Can't be done on stock Samsung. So I think it is gone.
Now when you say he did a factory reset are you sure he didn't wipe the card by mistake?
The contacts sync with Google and what most likely happened is that have been saving to phone memory and not to the Gmail account. Which he most likely signed into after the factory reset.
As for the back up there should not have had anything that could remove them from Google pics.
