boot time

I have about 160+ apps installed in my xoom, and it almost needs 1min50 secs to boot up. is this normal? what can i do to boost the boot up time? i m in stock 3.2

Uninstall some applications.

most of them are games.. i neednt to delete them right?

Use something like Titanium Backup to backup all your apps on Xoom (or any other rrooted android device) then uninstall the apps you don't use much/anymore/etc... It'll backup the app itself and the data that goes along with it (although it prob won't backup things like your game saves, just leave them where they're at on the sdcard whether it's internal or external). If you decide later you need the app again, just fire up TB and restore it, quick and simple. Sometimes after a restore of certain apps, you may need to reboot the Xoom to get all the functionallity back but aside from that, you get to keep your apps as backup and restore them anytime while reducing your overhead of having a pile of active apps that you don't always use...
This is what I do anyway on both my Xoom and my Epic. I typically don't uninstall apss through TB although you can, I just use it to backup and restore. I do the uninstalling through the normal system settings. That's just a preference tho...
Hope this helps!
EDIT - When I suggested this to you, I was assuming that your stock 3.2 setup was rooted. If not, then TB won't do you any good and the only other advice it what solarnz offered, delete some apps.

250+ Apps here, over 5 Minutes Boot Time. Running Tiamat Hammerhead and already Reinstalled everything once. Boot Time caused by "Unpacking Native Libraries" of every single application. I hate that -.-

Learnt something new i have 101 and thought itwas getting slower lol

200+ apps on my Xoom and the boot time is still solid as can be! For the rooters: Try using an app called Autostarts to disable all of those unwanted apps that make their way into the startup list. For the non rooters: Autorun Manager.
A lot of times, apps will attach themselves to the startup list even though they do not need it, such as a game. Why would you want a game booting up with your Xoom? I wouldn't, that's for sure. It's pointless, takes up memory, and it makes the boot time worse.
For the most part: Wipe out every single one of the startup apps that are not a part of the system, or as many as you need to. If you disable the user startup apps, you will have a more solid boot time no doubt. Almost none of the apps you install will ever need to boot up with your Xoom, unless you want it to. For me, I keep only a select few apps at startup such as: Equalizer, AdFree, and SetCPU. And chances are, if you have a ton of apps... your startup list will be massive, to say the least when you load up the app for the first time.
Rooters: Autostarts
Non Rooters: (Also has a root option) Autorun Manager

[How to] Get best app/gaming performance

I made this for people who saw that they're phones can do lot better!
For example, I have an Optimus One, and I get performance lot better than nexus one!
Things market with "*" need root!!! At your own risk, blahblah (wevall know the disclaimer!)
Please help if you know something else...
Here it is:
1. Storage place
If you have an app on SD, it will have the worst performance, because SD is hard to read... if you have no place for it (e.g. a game) just increase the SD speed* to the highest you can... (I get lot better performance when set to 4096 than on 2048)
Here is performance based on storage location:
SD<Internal<ROM (This is why stock browser is so fast on some devices)
So, if you have enough space on your ROM* memory, use apps2rom from market, or move the apps to internal, then take the apk from /data/app/ and move it to /system/app/, reboot and enjoy!
2. Overclocking*
This is well known, so nothing to say here...
Some devices, like the Optimus one, have same voltage at 122-480 and same voltage for 600-806, so overclocking will be actually better, because tasks finish faster.
3. Never clear cache, unless you need to!
Gonna make it simple: no cache, loading speed 100%... with cache, 140%,
Speed may vary from website to website!!!!
But, if apps have problem with checkboxes or something, clear it!
E.G.: a checkbox wouldn't open on browser, cleared cache and it worked...
E.G.²: the es file explorer showed me wrong icons... cleaned cache and enjoyed!
'4. No background tasks, but no task killers!
I use app swipe from market, it shows me what apps are open, in running tab... I swipe and it gets me to fc android settings window (I force stop the app from app details)
Task killers don't work for android 2.2+, it will just be an epic failure to your battery and system!
5. Autostarts*
IMO, this is the best app I have!
6. Clean up of useless apps (may need root)
On my Optimus one, the bloatware could be uninstalled, with an error, but it was uninstalled!
I used to have 150 apps, now I have 90 and I am happier! Performance rocks, nothing lost, awesome!
What system apps to uninstall... if it is not in the list, it is safe to uninstall!
7. Custom ROM and kernel*
Custom ROMs get rid of all the bloatware crap, is tweaked, and trust me, it is worth it!!
Kernels can make, actually, too much influence! They will simply simplify, or make it better, don't hesitate to use them!

Trimming ROMs for LG P500

As we know, JB and Kitkat ROMs have gotten much larger than their ICS predecessors. Flashing these and some gapps can easily run our device out of space on the system partition. Some apps will not even be installed, others will have errors. Even some hardware may not work correctly. So the ROMs must be trimmed to fit correctly.
In higher-end devices, they will be 1GB of system space. ROM-builders and chefs tend to dump everything on system as a convenience. Flash the ROM, a load of gapps and one has a complete-functioning system. What could be simpler?
For our oldie-but-goodie, we do not have this luxury. Even with micro-gapps consisting of an old Play/phonesky.apk and some framework will run out of space.
Really, anything not needed to get Android up and running does not need to be on system. There are some additional apps that require extra permissions afforded system apps to work. They need be kept there as well. But the others? Install as user apps. Then let link2sd or such symlink them out of the way (data space runs out too easily on our old phones as well!)
I trim the ROMs to bare metal. Not necessary to be so severe however. I ran ICS for a long time with 3 meg on system with no problems.
What do I remove, keep, etc?
1. /system/usr/srec (speech recognition stuff, most likely no longer in use!) I keep a copy on sd-ext and symlink to there. No problems.
2. Ringtones, alarms, sounds -- most of these have already been trimmed off the ROMs by the devs so I leave what they leave. Want more? Place in similarly name folders on the sdcard and Android will find them.
3. Fonts:
Linux, Android, XDA, are international communities. To save a small bit of space, non-Latin fonts have been removed from recent CM-11 and Omni ROMs. I objected, placed revert request on Jenkins. Raise those voices, folks. Many of us regularly use non-Latin fonts and languages. I keep all the fonts. The fairly large "fallback" font is usually missing on ROMs nowadays. Those using CJK languages or getting a lot of '?' in text should put it back.
4. Apps, apps, apps:
Calendar should be installed from Play. Take off ROM.
I install Apollo, Calculator, CMFilemanager, Cameras, Galleries as user apps. Work fine.
If one does not use live-wallpapers, take their apps off.
If one is using Google Search/Now (must be side-loaded as not fully compatable with our device and will not install from Play), the QuickSearchBox is no longer needed in system.
Google Play Services can be installed as a user app and auto-updates as such anyway. A version of Play, older and smaller the better, apparantly must be on system but the full newer versions should be installed as user apps and will be auto-updated as such.
Flash the tiniest gapps one can. Most all gapps such as Maps, Keep, Hangouts, etc., etc., are installable from Play as user apps.
.
5. Keyboards
The LatinIME with all the languages was ridiculously large. Recent ROMs only have English. There are numerous kbs on Play. One only needs a small kb on system to enter Google account on first start if one wiped data. Do not need swipes, handwriting, voice, dictionaries, etc. Since I do not wipe data, I do not even keep the LatinIME. But better to have a kb on the ROM.
Want swipes and languages without the bloat? Try multiling-o. Whole business is 330k and numerous!! languages install as user apps as well and do not eat up data space. Not quite as good as Swype or Swiftkey but pretty close, very light-weight, and very configurable as well. Note that recent paid link2sd versions can symlink app data as well so one can now have one's Swype or Swiftkey and eat it to
Interest in other's ideas and alternatives!

There is now an app on Play just for installing CM apps! Those include Apollo, CMFilemanger, DSPManager, etc. New there is a "CameraNext" which is NOT Focal. Says might not work. Does on my phone.
Anything available from this app can be made a user app, taken off system, symlinked away by link2sd. If the app is on system now, i.e. Camera, Messaging, et al, do not install from the app. Instead, force stop the app (avoid FCs after moving), link2sd convert to user app, create links. When flashing newer ROMs, trim the apps made user apps off the /system/app/ before flashing.
The weakness of this is that if the apps were upgraded, one might miss out. To check, compare apk sizes, dates. If seems like newer version, extract them before trimming and try an adb install -r.
This will gain some /system space and som /data space as well. However, the linked dalviks will be a larger total so will not help prevent link2sd "Achilles heel." More system space enables experimentation, placing something new there that needs to be.

I do it using KDE's ark. Have to downgrade to an older version to get it to work because they have not fixed the bugs in newer ones. Pain, but gets it done.
There must be other GUI apps to take care of this, for Android, Linux, Windows.
Otherwise, unzip the whole thing.

[Q] Best cleaning app

Hey ladies and gentlemen.
Can someone tell me what is the best cleaning app?
And i mean advanced cleaning, not something like clean master and such.
SDmaid is great, but i think it doesn't clean everything.
Many thanks in advance advance and sorry if its wrong section.
By the way i have Xperia Neo running ICS stock rom rooted.

What do you want to clean? You can use the recovery mode to wipe cache and dalvik cache, advanced enough?
Or titanium backup to clear apps data and stuff.
Hope it helps .

I don't know if I have used any cleaning apps specifically. I find that normally just deleting unused applications is generally enough. Everything is sandboxes and fairly self contained. Also never underestimate the size of your image lib. Always good to backup your phone and archive off pictures at the end of each year.

So called cleaner apps are all a joke. I would avoid them. Just do some minor cleaning yourself every now and then.

Cleaner apps do the contradictory action don't download them...
If u want free RAM then use
Greenify [root]
To cleanup the cache use recovery mode..

CCleaner. I got I for free from amazon appstore. It helps with cleaning,with a few clicks you can delete unneeded garbage.

Avoid cleaning apps
I strictly recommends you not to use cleaning apps they eat up more battery and RAM.:silly:

Those cleaning apps dont do anything other then place ads on your screen. All effects are placebo designed to make noobs think they are doing something great.

Actually, CCleaner has no ads, at least the version I have. Suffice to say, its a useful tool. Less menial work to do, especially when deleting many things at once.

Have you even looked at what it really does. These types of apps were put to the test years ago. They were found to be mostly pointless as they mainly cleaned up DB files what we're just redone on the next reboot.
And now with Android 5.0 they are even more pointless.

360Antivirus geek. Maybe.

I agree most clean up apps don't do much for you. I do like SD maid as it allows me to toggle whether or not certain apps run at start up, duplicate finder can also be useful at times.

Also use SD Maid to check its file's recommendations out occasionally. Interesting to see and optional to remove...

Dalvik-Cache, the cache partition and app cache is not the same. AFAIK no recovery targets app caches except when doing a factory reset.

The sandbox is pretty leaky though. Especially the sdcard is basically a huge free 4 all with developers thinking they are the most important app on the phone and stuffing files everywhere. Then there are also the cases where apps think their data should stick around because you "might" reinstall, who specifically make sure the data is not just deleted on uninstall.
If we put root into the mix, it's all fair game .

"Most" cleaner apps are a joke, but don't put them all in the same bucket . But i do i have to admit that the majority are a joke if not even missleading or straight scummy.

All the "RAM cleaning stuff" has been pointless since 2.2/2.3. Not sure what you mean that Lollipop has changed further, while external sdcard restrictions have been forced since 3.0 (in reality 4.4) it doesn't completely solve most issues, especially on custom ROMs or rooted devices where the restrictions are often deactivated as they are pretty inconvinient.
I'm not sure what DB files you are talking about, care to elaborate?

Interesting to see indeed, and pretty much how i think it should be used, but people want comfort and rather have the apps make the decision for them. Can't blame em though. Android has lots of room for improvement in that deparment, not easy to solve though. If they change the whole sdcard access system they could track file access of each app and use that data for security and uninstall purposes but i guess that would be difficult to do with the differences between each handsets storage solution. Also brings some performance penalties, and storage access already is one huge bottleneck on Android.

Thank you all for your answers.
I will just keep using SDmaid its best till now.
I dont want Clean master and DuSpeedBooster craps, thanks but no thanks.
Also CCleaner is pretty simple, i think sdmaid is doing better job.
I dont know how to use recovery mode, i never made it.
I am on ICS stock rom rooted, maybe its not even possible for me to go into recovery mode.
Yeah lolipop is great but my phone wont get it and i cant get new phone so Lolipop is nowhere near me.
Cheers

Debloating The SM-G360T1, SM-G360T & Others: An Easy Guide

There's not a lot of information out there for the Galaxy Core Prime on how we might debloat and save more space, so I decided to make a short tutorial that might help people with some easy steps in cleaning up their device. This guide is meant to be pretty basic and to just help point people in the right direction so that it speaks to a broader scope of Galaxy Core Prime Models, but is based specifically on the SM-G360T1. The SM-G360T is essentially the exact same phone though, so all of these steps should apply directly to that device too. Other Galaxy Core Prime models will be able to use this as well, but just be sure to read the special "NOTE" part of each step. Also, I'm sure it goes without saying, but inevitably I'll get the question, so obviously, root is required for this!
Anyhow, here we go:
1) Do a full backup in recovery before deleting system stuff. This is always a good idea just in case you delete something you're not supposed to and android stops working, then you can just go into recovery(TWRP, CWM, etc.) and restore your backup and your back to square one. It's good to do a new backup too a few days after when you're sure your deleted apps aren't causing any problems so you can restore to that slimmer version later if need be. Also, you should probably save your backup files to the external sd as you will likely have more free space there.
2) Install a debloated rom in recovery. SlimPickins is a great one for the SM-G360T1. It's basically the stock firmware for the MetroPCS Core Prime, but thanks to @Koognod we can now run Android without all the extra junk using his rom. It comes already debloated, deodexed and deknoxed, so you can just install it and not have to deal with finding all the junk to delete for yourself. It's already gone! It's also great for speeding up your bogged down phone or creating more space for your apps and media. Here is the link.
http://forum.xda-developers.com/gal...rom-slimpickins-stock-rooted-bloated-t3250883
NOTE: YOU CAN NOT INSTALL THIS ROM IF YOU DO NOT HAVE THE SM-G360T1. It should work fine on the SM-G360T too, but for anyone else just try googling or searching XDA for your "model #" and "debloat rom".
3) I recommend deleting the "PreloadInstaller" folder from "/system/app/" with a Play Store root browser. You should do this before deleting any system apps in my opinion, as this folder contains an apk that is programmed to put back a lot of the system stuff you delete(either immediately or after reboot). If you don't feel comfortable deleting this folder just yet though, then you can just move it to your external sd card for now with your browser to save space in case you ever want to move it back or just skip this step. Your choice!
NOTE: If you don't have the SM-G360T1 or SM-G360T, then your "PreloadInstaller" folder may be called something slightly different or you may not even have it at all. Just look for something similar in there. Be careful not to delete the package installer though as that's the program that allows you to install apps yourself.
4) You need an app that uninstalls system apps. I use "System App Remover(ROOT)" from the Play Store personally because all your deleted system apps actually go into a recycle bin first where they can be restored later if needed. It also tells you if the app in question is a "Key Module"(ie. proceed with serious caution).
5) Google search the internet for system stuff that's ok to delete for your device. It helps to search your model usually, but I don't think there's much info out there for the Galaxy Core Prime unfortunately, so just searching something like "Debloat Samsung Safe" can be a great resource as many Samsung phones have the same system junk.
6) Delete all the obvious stuff you don't want. This would be things like any of the MetroPCS stuff(or whatever carrier you have) or even the Galaxy app store if you don't want it. A lot of Google apps can be deleted too, though you want to be a little more careful with those as Android is pretty much based on the Google Services Framework and many Google apps are tied into the system. Generally, apps like Chrome, Docs, Drive, Hangouts, Maps(if you prefer another map application like Waze or whatever), etc. are good to go if you want. I wouldn't delete any of the core Google apps though that may handle major processes on your phone, like Calendar, possibly even Gmail or any of the ones that you don't know what they do. Deleting the stock camera, gallery, video or music player may sometimes give you problems down the line too, so I would probably keep those. You can also back all your apps up before deleting with Titanium Backup from the Play Store too in case you delete something that you need to put back later.
*NOTE: Some apps, like the Google ones for instance, may cause popup errors after you delete them. This is normal. Your phone's just looking for all those files that were just secretly running a few moments ago. All you have to do is reboot to get rid of those messages. If they still persist, then just reinstall the app.
7) Download an app to clean up that leftover mess. When you delete an app, especially with system stuff, it often leaves a bunch of folders and junk behind. Go to the Play Store and download an app that allows you to clean all that up. There's lots of good ones. I like to use one called "SD Maid" myself. It's good at cleaning up those leftover files and has a feature called "CorpseFinder" in fact that does just that. It also cleans up a lot of other things on your phone.
Anyhow, if you're a heavy power user like myself or you store a lot of music or other media on your phone in addition to 20 million apps or so and you need more space, then I hope this helps you out. Take care guys. Thanks!

Out of curiosity, how does this affect the "phone unlock" feature? In case I want to change providers?

It won't affect it at all as long as you don't delete the "Device Unlock" app. More info on unlocking your device here:
http://forum.xda-developers.com/showthread.php?p=63729887
Also, you can just install SlimPickins if you want an already debloated rom.
