Which /system apps can be safely uninstalled? - Sony Xperia ZR

I have recently upgraded my Xperia ZR to Lollipop 5.1.1 stock Sony ROM. I have rooted it. One big irritant I am facing is lack of internal storage space. Among the main culprits here are apps in /system (both /system/app as well as /system/priv-app) that are taking up precious space in internal memory (only 4.6 GB is user available out of total 8 GB) in the form of .DEX files.
My goal here is safety first. I know that I may not need them now, but I should be able to install them in future if necessary. Hence I am mainly looking at applications that are not required for normal functioning of the phone and could be installed from the Play Store if necessary later (considering that so many are already on the Play Store including many Sony applications)
Do all these applications necessarily need to run as system applications for their proper functioning? If I can install them as a regular user app, I can use Link2SD and send both the APK and DEX files to SD card with a link on internal memory thus greatly saving space.
Here are some I have shortlisted:
Google applications
1. Maps
2. YouTube
3. Google Search (the APK is called Velvet) - I do not use Google Search app, I do not want OK Google.
4. Drive - I do not use it now. May be in future.
5. Chrome - it is just a browser. Will it not work equally well as a user app?
Sony applications
1. File Commander (not exactly a Sony application but available on the Play Store and is already pushing ads, is there any unique functionality that only File Commander can provide and not other file browser? WiFi Direct?)
2. Album - is it not available on Play Store too? Can I install it from there?
3. Movies - same as Album.
4. Walkman or Music
5. What's New - not needed for me.
6. Movie Creator - I doubt I will be routinely stitching up videos on the phone. Still it would be nice to have in case needed in future.
7. Podcast - I do not listen to podcasts now but in future if the situation changes.
8. Movie Creator - there are 2!!!!!
9. Xperia with Facebook
10. Xperia Lounge Pass
11. Sony Music
12. Xperia with Twitter
13. Xperia Calender Sync - seems to deal with Facebook
14. Xperia Social Engine****
Please go through the list and suggest.

Greetings, you are on the same boat as I am, and yes I have uninstalled all the apps you have mentioned in the list. I have deleted even some other apps too. Also you may wanna keep "whats new" >> This app is like the update center so any new OS updates will be shown from here only and Xperia ZR will have a bug fixing update soon.

Thanks. Could please tell me the other applications you got rid of?
I will keep What’s New then.
Are we probably the only 2 active ZR users? [emoji13]

Webview is needed by many applications to display webcontent right? What did you mean by 'its same bugs'?
Exchange probably is related to Microsoft Exchange which is a corporate email thingy(?) and hence I too may not need it.
What about Chrome? I actually am a Firefox person but some sites may need Chrome. Hence I want to keep it but does it really need to be a system app?

For example ; Application details in Google play store can't not show.. Iys says play store stopped.. And My sms Application Truemessenger is too.. Stopped..
I don't use Chrome.. Deleted.. I use lovely Dolphin browser with Flash.player

I don't remember them now, because using CM. Also why not try TB feature ? If space is your concern, sort apps by size and you will get which useless app is eating your internel memory. Also use "backup > verify > uninstall app" when un installing imp system apps. If they cause FC , you can restore them later.
Yeah its a pretty old device, soon you may be the only one (Hunting for the next Mobile )

Also some apps may seem like redundant (2 movie creator apps ) but in reality they are very useful. One used for merging and editing Video clips and the other used for PlayMemories Slideshow for album. These apps are very small in size and doesn't clog your internals. Look for the big one.

You shouldn't uninstall system apps, as they won't free up any space; if you want to free space, uninstall the apps on the /data partition, i.e. the apps that you can uninstall normally. If you want to improve performance, just disable the app in question. Deleting it does absolutely nothing that disabling wouldn't do at much less risk. I'm a little surprised nobody else has pointed this out.

Does anyone know of any program i can use to directly stop these unwanted apps to stop running every time, or any individual information on the programs?
cheers
Why do you not want them preloaded?
The main reason im being such a memory whore is because my launcher lags like crazy under 70-80mb. I have 250ish apps, and see many people with a similar setup demonstrating on youtube, and theirs is instantly responsive, as is mine >120mb free. If I leave all these apps etc free, i end up on ~40mb which makes my old nokia 6300 looks like flash gordon compared to my launcher :/
Re: Apps seem to open themselve sin the background when they
Android preloads apps into its memory for fast load times.
Just because an app is loaded does not mean it is using any resources. They're usually just sitting there idle. Android also frees up memory as needed.
That said, I've seen apps that can control what apps you never want preloaded. Search around on the market.
Looks like the slowdowns from a lack of ram still exist. I hope froyo will help with this. This problem makes the lower end android phones run slow.

[Q] Couple of days in - a couple of Qs...

So after some great help by gregbradley and others, I have a rooted T and now have an OTA 195 update.
However I have a couple of questions (apart from my continued quest to find a way to get the phone to save camera output in less compressed fashion.
1) Is it usual for mediaserver to be the 2nd great drain on battery after the screen and ahead of android system?
(there appear to be many web discussions on this, but I could not find a definitive answer. Mine has always been like this even before I tinkered with it, or before I put the sim in (I didn't put the sim in until after I had rooted and updated. I do not have an SD card in there yet (64Gb on order) and I have not added any new pics or movies to the stock provided ones.
2) Can you change where apps are installed? Can this be changed for Google Play apps (like xda) Is the default to install to "phone memory" rather than "internal storage". Given that "phone memory" is only ~ 2Gb, it would be good to install to "internal storage"
3) Are apps on the home screens (eg Walkman) always running, even when not in use (the walkman example is the app 4x1 icons wide and has basic controls on it)?
Many thanks as always!
icstm
some clarification I should have added yesterday...
1) quite simply I would be keen to know what type of apps call on the mediaserver process
2) I know that from the "apps" in settings" some apps can be moved, but that appears limited and no default can be set
3) when I say apps, I mean widgets and the like, not the simply shortcut icons

1) Anything that needs to scan the sdcards for contents will call on the media server. After a fresh flash many apps will be collating their cache so the mediaserver may have a high battery drain, you should never worry about battery drain untill you have run a ROm for at least 3-4 days to let it settle
2) Yes, use apps such as link2sd or app2sd, free in the market. However I have not yet felt the need to do this with a 16gb internal memory
3) Thos e widgets are just shortcuts, e.g. I have a weather app set to refresh every 2 hours...it will be woring in the background whether or not the homescreen widget is on the homescreen or not.
However, do not worry about task killers, since android 2.1 the best task killer is the one that comes with the OS. The only other exception is if you install init.d scripts and supercharge scripts etc, but you may want to leave that for a bit and get used to the phone first.
So I am on the xda app, much better way to view the site than mobile browser .
However, I cannot see what you wrote when I reply.
But it relates to your last point on making customisations. And not just keyboard which prefers US spellings over UK ones .
I am thinking of tinkering with the OS files as I am very upset with the compression of photos. So I am keen by what you say just below number 3.

AW: [Q] Couple of days in - a couple of Qs...
Change your keyboard or even better your whole phone to UK in language and keyboard setting and it'll propose BE instead of USE.
Greg is correct, the media server goes nuts the first two to three days after (re)flashing or taking up a device. You can improve the situation by keeping your folder structure clean and neat and trash out left over files, old garbage and file system junk.
Thanks for your posts in both threads.
As for mediaserver, yes all is quiet now.
Not sure about which system files to delete at this stage, but I sure do keep a neat folder structure for my content.

Move Apps to SD Option?

Hello,
Waiting for my Z3 Compact to arrive. I can't wait!
Question for you owners out there. Did Sony add the option under storage settings like they did with the Z2 to move apps to SD?
Fingers crossed!
Thanks in advance!
Would like to know myself. Seems like a boneheaded move if it's not an available feature by default. I mean, I know eventually root will allow us to achieve apps2sd even if it weren't, but it would be such an Apple move if this were a restriction.
I could only see 'Transfer data to SD card'
Photos
Videos
Music
no apps or any other options yet.
App2SD is not present and I'd predict that it'll also not come. I'd already be happy if we could get write access to the SD. Thank you Google... no, I don't want to use your Cloud "services".
Can you set pictures, videos and Music to get stored on the SDcard by default? Setting the location by default would make things much easier. Not too worried about 16gb for apps, always was fine for my N4 with everything else as well. Just needed to clean up storage every once in awhile.

Anyone found a solution to this, running low on internal storage!
Luckily Google will bring back Apps2SD in Lollipop. Now we just have to wait, till Sony releases a LP rom...

Where did you read this?
Google only said:
Google said:
Hey all, in KitKat we introduced APIs that let apps read/write file in app-specific directories on secondary storage devices, such as SD cards.
We heard loud and clear that developers wanted richer access beyond these directories, so in Lollipop we added the new ACTION_OPEN_DOCUMENT_TREE intent. Apps can launch this intent to pick and return a directory from any supported DocumentProvider, including any of the shared storage supported by the device. Apps can then create, update, and delete files and directories anywhere under the picked tree without any additional user interaction. Just like the other document intents, apps can persist this access across reboots.
This gives apps broad, powerful access to manage files while still involving the user in the initial selection process. Users may choose to give your app access to a narrow directory like "My Vacation Photos," or they could pick the top-level of an entire SD card; the choice is theirs.

you can set the default image/video location from the camera settings, read somewhere that you can do the same with music via the play music app.
Okay probably got that wrong, but on the other hand effectively it's the solution to the problem. If the apps can easily store their biggest part of data on the SD, the internal memory will be save.

[Q] How can we discover what each of the apks actually are from the package files?

Hi All,
I haven't had much luck with the questions I've asked, it's a shame these forums aren't more active but I'll try my luck again (and thanks in advance to all those who read).
A lot of us newbies who want to debloat our phones are unsure what apks to delete and what needs to stay. I've found various lists of apks that others have deleted, but with no indication of what they are exactly are. Some are obvious but others are not.
I, for instance, can't figure out which apk produces Video Unlimited, Smart Connect or Xperia Care Support from looking in system/app with the root browser. Is this even the only place I'd need to delete each apk from to remove it? But I digress.
So there surely must be a way to read each package and view or extract the user-friendly name that appears to the user in the Apps list or in the home screen. Can anyone tell me what it is? I would be very happy to go through each apk and list it out for people to then use as a reference, and we'd have one more resource for newbies to draw on, instead of us just deleting them blindly and/or at random.
Cheers as always,
schnidex
Use ES File Explorer and check the "App" menu. You will be able to see the apps by its user-friendly name, and clicking on each one you will see its package name.
- Install ES File Explorer from the Play Store (it's free)
- Press the hamburger menu (located up-left -> Library -> App)
- You will see user apps, then you can click on the menu and check system apps or all apps installed.
If you are rooted, you may uninstall system apps from there (long press, uninstall located down-left).

¡MUCHISIMAS GRACIAS, MI AMIGO!
:good:
The problem is not in knowing which APK belongs to which app (and sometimes one APK is several apps at once - like Google+, and you need to know it, and sometimes you don't see an app at all for the APK, like for most system APKs). The problem is knowing what the app actually does, which parts of the system rely on it being present, and how well will these parts behave if the app is removed (vs disabled, which is a normal way to deal with unwanted apps). And this is where "debloating" can do more harm than good.

True in many ways, but my primary concern was removing the apps that appear in the app drawer. This seems to handle that perfectly.

Device getting Slow(Moto G 2nd gen) non-rooted

I have had my Moto G2 for more than a year now. But with recent Android 6 update some things improved but phone started getting slower and lagging. I have tried factory reset but still has issues. Maybe it uses too much RAM.
Please give some suggestions.
Thank you

Did you find any solutions
Use Greenify App ........its help u..
Stock 6.0 is very buggy, flash los13
This is what I strongly recommend doing. I tried everything that could be tried without rooting, as I think unlocking the bootloader and using customized software doesn't give you the reliability of the Moto apps, and it doesn't provide an acceptable level of security. If you have an unlocked bootloader and a custom recovery your passcode is useless as it can be bypassed in minutes. You don't want that.
* The #1 culprit is accessibility services. Even if one single thing is enabled in accessibility, Android is going to slow down hard. Android's accessibility settings allow apps to gain special permission, and stuff like that makes it possible for Braille back or any medical device to be able to get deeply tied into the OS. When an App starts an accessibility service, it gains special services and it becomes tangled to the OS so deeply that Android will start logging every little thing you do. That's great if you have special needs and you need something like that to use your phone, but if it's just some cool App, it's really not worth it.
Head over to settings, accessibility and make sure everything is toggled off. On top, you'll see a list of Apps. Get inside all of these sections and turn the toggles off.
* Cut down on Apps. The more you install, the worse it gets. Very simple. Strive to install Apps that are small in size and that don't use much RAM. You can see what's running in the background in developer settings (Google how to enable those) > running services. If you see any App running that shouldn't be and it's not essential, it must go. Anything you haven't used in the past 60 days must go. Whenever you find you have an App you never open, even if it's super small, just get it out of the system. Not only is it good for your phone, but it's also good for your own sanity and balance! Do some research. You'll find that the excellent suite of Google's preloaded Apps is already enough for pretty much everything. Many of the features are pretty much hidden or not advertised, but they're there. Your phone was designed to be usable from the ground - up, only install apps for things that you can't do natively i.e. chatting using WhatsApp, social media, Spotify, an RSS reader, Google Keep, nutrition tracking apps, Uber/Lyft and so on and so forth.
* See which of your Apps have web versions. Uninstall the App, and create a shortcut for the web version in Google Chrome.
* Free up storage. Strive to keep as much free storage as possible. Get a file explorer that's not ES and delete folders from apps you no longer use. Dig through WhatsApp > Databases and delete all the outdated ones. Get rid of all the unwanted, old photos, videos and voice notes left behind by messaging clients. Go through that mess your Downloads folder it and simply get rid of things you no longer need. Get rid of your screenshots too. Save the important ones in another album.
* Reboot on a regular basis. I'd say, turn your phone off and back on every 2 - 3 days.
* Use Google Photos's "Free up storage" to get rid of local copies of pics and videos that already safe and sound on your Google Photos account.
* Don't use Greenify in this day and age, especially if you're not rooted. It uses accessibility and, as you might expect by now, right, it's counter - productive. Your phone already does a good job at freezing Apps you don't use after a long period of time starting Android 6.0
* If an App keeps running in the background, consuming too much RAM and misbehaving, force close it. Get it from the App drawer, drag it to "App Info" and go "Force Close" on it. Android will get the hint and it won't let it start back again unless you so choose.
* Wipe the cache partition. It does not require root and there is a very nice guide on the instruction manual online. It doesn't delete any personal data and it works wonders.
* To wipe cache, head on over to settings > storage > internal storage > Cached data. Tap it and tap OK.
* Chrome caches a lot. Get into its app info, then storage, then clean data. Tap the first button: Chrome will delete cache from websites it deems unimportant, so you'll still have all the cache, cookies, history and login info from your favourite websites.
* If you have any App that promises to make your phone faster or free up storage or prolong the endurance of your battery such as Clean Master, DU Battery Booster, HTC Boost + etc etc get rid of that too. They're counter - productive and overall bad. I could sit there for hours giving you reasons why they are useless. The same goes to antivirus software.
* If you use Facebook, either uninstall it and use it on Google Chrome (it pushes notifications too!) or switch to Facebook Lite or Swipe. Also delete Messenger, as the web version and the external clients deal with that too. Again, if you prefer, use Messenger Lite instead. Or just don't use it on your phone at all and gain a lot of free time.
* Consider giving up on Snapchat as long as you have this phone. It's just too much. I got rid of it and I'll hop back on on my next device!
* If you use any cloud service other than Drive, buy Solid Explorer, add the cloud service and delete its proprietary App. Solid will be more than enough to run it.
* You don't have to keep Motorola and Google apps you don't need, such as Google Plus, the almost dead Hangouts or the discontinued Assist. Simply drag and drop them to "App Info", and then "Disable" them. Actually, do it. These apps are super demanding in terms of storage and stuff. As soon as you turn your phone on they don't make an impact on your storage, but as soon as they get updated the original App gets frozen and a duplicate gets installed in the user memory. That is, YOUR storage. Disabling Apps will get rid of the double copy and freeze the one that's in the system partition, storage you can't use anyway. Say: Google Play Books keeps running and it uses 200+MB, but you're a Kindle user like me and you couldn't care less about Google's own objectively inferior e-reading competing service. Simply disable Play Books and boom, your phone's a little faster and you've claimed yourself well over 200MB!
* The best security is common sense. Only install apps from the Play Store and disable unknown sources in security. Really, it has everything you need and more.
* Nova Launcher. The preinstalled launcher is great and lightweight enough, but now that it's on the way out I notice it slowing down and randomly being unreliable and not showing anything on it. Nova is graphically the exact same, except it's a lot faster and more optimized. Caveat: you'll need to open the Google App to access the Now feed.
* Delete all the data out of Play Music and set it to "Downloaded only" to prevent it from getting so huge again. It apparently doesn't always save to the SD card, and we can't do that on an 8GB phone.
* Disable the HP Printing service if you don't have an HP Printer.
