[Q] Why there is no uninstall feature in Android?

I have about two weeks experience with Android OS and as a software developer I will be interested to know the technical details behind the Android OS.
I have already noticed this is possible to upgrade applications ported with the handset's ROM i.e. the Market app. This raised the question to me why can't I uninstall applications from the ROM without rooting or risking my handset's warranty to achieve this?
Is my expectation as a user of computers for 20 years unreasonable to think in 2010 with all software development and technological advances the uninstall feature should have been in Android OS from day one?
This is not exactly like Google is the first company in the world developed an OS to just the lack of experience with what users would want. From what I have seen so far in world of Android is that, the first thing users would want to know how to root their handset to remove packages that they have no use for.

My guess is that Google doesn't want users removing Systems apps. I'm assuming that they think that these applications are core and thus don't want you removing them. Remove the market, no more apps... or way to get it back etc.
Applications installed by you can be uninstalled, I'm just thinking it is the same as in windows, you can't uninstall the task manager etc (Bad example but meh =P)

Very simple - to prevent lay users from removing critical components.
Can you imagine the service costs involved in reparing devices that that have been damaged by people trying to remove bloatware?

They still give you the option to restore.

OK DISREGUARD THIS AS I MISSED THE PART ABOUT NEEDING TO ROOT!
They can be removed but its not recommended to do so without know EXACTLY what your removing and weather is vital to your phones operating system.
BUT in order to do so your phone needs root access, and root explorer installed. There are several forums on just about all android support sites that explain how to root, install the manager, and which apps/files NOT to remove.

Ye u can remove almost every stock app but this may affect the stability of your phone, modifying your phone always comes with the option restoring it back to default. If something goes wrong with moding (something really hard and extraordinary rare ) u can restore it. Browsing through Xda might solve many questions, we all didn't wanted stock rom (not because it was bad, because we can have s omething better. This community has VERY VERY good developers.
Androids own!!!

One thing I still don't get is...
How can Google upgrade Market app without the su privilage but the rest of the world has to root their phones to remove bloatware such as 'amazon mp3'?
@ftgg99: How much bloatware in Windows cost Microsoft or PC manufacturers? None in fact they get paid to include them with your hardware. However, I see an issue with mobile devices. You have already paid for the ROM storage, the bigger ROM size is the more expensive your handset would be, then the manufacturer uses your already paid ROM to make even more money by installing bloatware. I would be a fool to think manufacturers would pass on a percentage of the bloatware earnings by reducing the cost of their products to the consumers in this model.
The way I see it, the burden has been put on the communities such as xda. Users wouldn't ask the manufacturers how to root their handsets and this is left to the dedicated individuals to overcome the mess compnies normally leave us with. I'm not going to say the mess is a cost saving measure by companies.

The thing is that there are a lot more people buy and use phones than computers. After someone buys a smart phone with intention to use for calls, text, web and to use some apps, they realize the possibilities of the smart phone, they start digging in to the files, therefore Google blocked the root folder from modifying, otherwise Google would have to repair warrantied phones that didn't have to end up there just because people didn't know or care what they did. But if you got passed ROOTING, you must know what you are doing and from this point you can modify files and apps, but now ROOTING becomes too easy.
Basically just because too many juveniles got their hands on the equipment.

The answer, from my point of view, is quite simple: they just upgrade the application on /data/app ON TOP of the /system/app default Market version. So, you can always go back to your "default" version just by "uninstalling updates".
Summary: they do not upgrade the Market form ROM, just install the new version on top.

Have you tried to work with iPhone(don't know about iPhone 4)? They build fortress around their system and even the apps you install cannot be uninstalled until you gailbrake it and use 3rd party installer to uninstall. And not talking about the "MONOPLY" they run with AT&T.

[Q] What to do with HTC Desire HD?

Hey
Im kind of behind with Smartphones because I had a Samsung D500 for several years, it was only a few months ago I upgraded and got myself a HTC Desire HD on Contract. Ive been using it completly standard, with all the official software etc..
Im beginning to get quite bored of it now though and I still have like 1 and a half years left on my contract.
All I seem to do with the phone is... standard SMS texting, phone calls, facebook, twitter and check a couple of websites every now and then.
I have read around and hear things about "ROMS" and "ROOTS", but dont really know what that means.
Im just wondering, if you had this phone.. What would you do with it exactly?
Something to make it look/feel like a new phone maybe..... I duno
Just want some opinions, recommendations really
Thanks

Custom ROMs
A stock ROM is the version of the phone's operating system that comes with your phone when you buy it.
A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc - everything you need to operate the device, except it's customized by someone in some way.
So what does the "customized" part mean? Since Android is open source, developers are free to take stock ROMs, modify them, strip them of garbage, optimize them, add things, and pretty much do whatever their imagination and skills allow.
Custom ROMs are oftentimes faster, more efficient, and use less memory because:
- the developer ripped out useless garbage, such as carrier installed apps or
- the developer optimized the kernel. For example, an undervolted kernel can provide a much better battery life than the stock one.
You can upgrade to a version of the OS that has not yet been released for your device, or never will be. This is possible in 2 situations:
- A leaked version of the new ROM showed up online, and the developer got on it like the fat kid chasing an ice cream truck.
- A ROM from another phone was ported by the developer to work on yours. For example, G1 and MyTouch 3G users may never see Android 2.1 officially released on their phones, but Cyanogen, one of the most respected Android developers, was able to create a custom ROM running 2.1 for those devices.
ROOTING:
Getting root or rooting your phone is the process of modifying the operating system that shipped with your device to grant you complete control over it.
This means you can overcome limitations that the carriers and manufacturers put on your phone, extend system functionality, and even upgrade it to a custom flavor of Android.
The name root comes from the Linux operating system world, where the most privileged user on the system (otherwise known as Administrator on Windows) is called root.
You have access to alter any system files, use themes, change boot images, delete annoying stock apps, such as Sprint's NFL Mobile live and Nascar Sprint Cup Mobile, and other various native applications that might drive you crazy (Footprints, Voice Dialer, etc).
On most rooted Android devices, you can back up your entire system to an SD card, much in the same way you can image a hard drive. This is great if you’d like to try a new ROM, as you can back up your phone, wipe it completely, flash the new ROM, and if you don’t like it, just restore from your backup to get your device back to exactly how it was before you wiped it.
The easiest way to do this at the moment is by using ROM Manager.
ROM Manager allows you to easily flash a custom recovery image which is what you will need in order to backup and restore your phone. The recovery image is a special program that can be booted into outside of the phone's main operating system, sort of like an OS recovery console on a PC. By default, the recovery image on most Android phones only gives you a few options, mainly related to wiping the phone. Custom recovery images expand upon these options and usually include scripts that can do things like backup and restore your system, fix file permissions, or allow you to flash custom ROMs that the normal recovery image would otherwise reject.
Normally, flashing a custom recovery image requires some command line work, either on your PC, or on a terminal emulator directly on the phone, but Koush's ROM Manager should automatically flash his custom recovery image (known as ClockworkMod Recovery) for you, provided you're on one of the supported phones and that it is already rooted.
Using ROM Manager is pretty simple. Download and install the application from the market, fire it up, and you’ll be prompted to allow the application superuser permissions - make sure you approve it.
The first thing you’ll need to do is flash the ClockworkMod recovery image that I mentioned earlier, which can be done right in the app (it’s the first option). ROM Manager should automatically find the latest version of the right image for your phone, download, and install it - the whole process is seamless.
After that is done, you can simply use the ‘Manage and Restore Backups’, and ‘Backup current ROM’ options to, well, backup your current ROM or restore from an existing backup.
Rooting Guide for Desire HD
Desire HD ROMs

If you're bored with the look and feel of the phone then by all means customize it. Custom ROMs etc can help with that, or even just trying another Launcher like ADW EX. Make it a project to do something creative and artsy and then post your work here. Rooting will allow greater scope of what you can accomplish, like changing the system Fonts, for example.
Really though, if you're not interested in that kinda thing, i'd suggest just doing more of what the phones are designed for in the first place, which is running applications. Perhaps you might edit your OP to request a list of entertaining apps so that people can throw out suggestions?
A few time killers that i enjoy:
IMDb (For watching trailers and reading about movies)
Cracked Lite (Funny and informative articles)
Amazon Kindle (Reading books on the go)
Wimp.com (Fantastic collection of videos. Think of it as youtube's greatest hits)

Heya thanks for that reply
Well I am interested in a custom ROM, it sounds cool. Especially if it removes crap I dont need to save my battery life etc
Id like to try a new ROM, I had a go last night and installed ROM Manager but it said something about it couldnt find superuser and told me to google it lol, so I went to sleep
Now I am awake I am willing to give it a bash and would like to do it
Dont think Id be much use trying to do my own though,would rather use someone elses if Im allowed too? A very fast/power efficient/nicelooking/stable one etc.. Any you recommend?
Just doing that successfully would be a big enough project for myself as its my first time Heh

Before I go ahead and break my phone, are these instructions the correct ones for me?
Shall I do what this says to setup superuser?
pocketnow.com/android/how-to-root-your-htc-desire-hd

Sorry I just noticed you have a big massive link with a guide for rooting my phone lol
I am going to do that now then thanks

As for ROMS, for my phone, is:
[ROM] MIUI 1.9.16 v.1: Freshly Squeezed Edition™ 16/09/11
The main custom ROM for me?
Would you recommend that one, from that link you posted, that one seems to be the only main one I can see

Need abit of help, got visionary on my phone. Ticked box r/w after boot or whatever and then when I click on Temproot now, it says rooting device etc.... but then it just goes to a black screen and stays a black screen.
Is this normal or is something going wrong?
- Apparently the latest firmware doesnt allow Visionary to work. I need to downgrade to an earlier firmware? How do I do that lol
Or should I just give up and stop now?

You have to downgrade to Froyo 1.3.2 first. Follow this guide.
Here's a guide for rooting, ENG and Radio S-OFF, Flashing radio and ROM

Flashing a radio?
Um this sounds abit to risky actually for my first time.
So from what I understand is, I could successfully flash my chosen custom ROM but the radio signal for phone calls/SMS texting and stuff.... could not work ?
I dont think I want to take that risk now Ive read that

dont flash any radios the one you have will work fine also have a look around in the dev forums.

Im quite happy with what Ive done, someone mentioned to do it earlier on in this topic and its basically all I wanted, just a fresh look
I changed the HTC Skin to Slate, and then used the GO Launcher and using a green + black theme, done abit of customizing. Before all this I did a hard reset on the phone too, and using JuiceDefender. I like it, happy with it, feels fresh

Thanks for all the help and advice though I do appreciate

[Q] android help anyone?

Well I got my galaxy s2 on release day and being a former crackberry addict I have no idea what to do with android. I understand that there are endless possibilities but I have no idea where to begin. Anyone know some stuff I can do to make my android experience simply better?

in same boat
i am not only new to andriod, i am new to smart phones. that said, i have had my andriod for a month. i have done a lot to it just by reading posts here and in andriod central. andriod central seems easier to navigate by phone choise than xda.
my wife is still a blackberry adict. after gettting my phone she wined about how much i could do. she still likes the blackberry and has found ways around the issue or boasted about something she could do that i cant.
this is just from reading about backberry so feel free to correct me if i am wronge. the PC device manager allows you to modify your phone. ie change theme, apps, ect.
the biggest issue most andriod owners have is that they cant get rid of the carriers apps(bloatware). most of these apps take up space, run when not in use, use up your ram. as far as i am aware the only way is to root(gain administrator acess) the phone. then you can get an app that will freeze the unused, unwanted apps(titanium backup,pay for version).you can also delete them, but i read it could be hazardes. recomend reading manual. i wont do it any justice, so info on rooting is everywere, i do suggest andriod central.
if you dont care about the apps then dont root. you cant get multiple home launchers,ie go launcher, launcher pro, adw launcher, theres more. i prefer go launcher, it lets you customize the most, ie change icons, the way the app drawer functions, the way icons function, different functions for the direction you slid your finger on the desktop.
with a rooted phone you can get custom roms to change the look and feel of the phone. what i understand flashing a rom to be is installing a new operating system, its like someone took andriod OS striped it down to just the OS and then added what they feel should be there for apps. generaly they just get rid of the bloatware, optimize the system, and a few usefull tools.
i have rooted my phone. sadly no custom roms yet. freezed most of my bloatware, freed up a lot of space. changed my desktop. got a wifi tether app so i can hotspot my phone with out having to pay for the data plan. any way i hope this helps. if you have anymore questions feel free to ask.

to expand on the topic about rooting (assuming that you take this route), here are some rooting methods (android version-specific):
z4root (2.2/2.2.1)
SuperOneClick (2.2/2.2.1)
Gingerbreak (2.2.2)
everything you can possibly discover about your phone (roms, kernels, themes, etc) can be found in the sgsII's forum:

"To Root or not to Root?" that's the question...

I don't want to know how to root, I can find my answer for that on Google, however what I don't get is what it does...
I know it unlocks the device somehow, but can't I simply access everything in the system if I compile android from source and install it on the device?
I have downloaded the android source and I believe I can access every possible thing, so why is rooting needed?
If I install an app as a system app, won't it automatically have the permissions to do what I need it to do?

AFAIK rooting is for the people you'd call the end user/consumer or whatever.
If you have a new phone and want to install one of the many custom ROMs around, you simply need a rooted phone.
A custom ROM is in easy terms a custom made User Interface for the phone.
There is lot more complicated stuff going on under the hood, but in general you change the look and feel of you phone's UI.
The phone has to be rooted, because the manufacturers and net providers around pack a lot of useless crap called "bloatware" (like Samsung Shop and Samsung Play and Samsung Sing and Dance and Music and whatnot) on your phone, which often makes it slower than it can be without it.
But naturally the big corps don't want you to be able to get rid of that **** too easily, which is why you don't have access to the system folders as a normal user.
I guess in your case it's possible that you (if you compiled android from source and installed it on your device) so to say have an already rooted phone, since Android itself is rooted by default. Like I said, the manufacturers are the ones to unroot Android in order to dictate which apps their customers might or might not use.
But I'm a noob and am not sure how you would install Android on your phone if it's new (and unrooted by default?) if you haven't rooted it before?
meh, hope that helped a bit at least...

root- you would love to do it after reading this..
Root? what is it?
it is what i call full access to our phone, flash new roms, have dual boot (example- you can have to os like ics and JB), can access the evasive /data folder which holdes the apk/setups of apps installed from playstore and many other things..
If you are concerned about warranty you can unroot your phone and give in your phone for warranty. i have given my phone for warranty like this.
The most important thing i like about root is that i can fix my phone myself (if it is a software problem). any other question please ask, and i will answer it.
Thanks if helped!

I don't have the time for development anymore. I used to play with stuff like that years ago, but life has taken me away from it. I'd still like to be able to access everything on my phone and play with custom roms, and root lets me do that. The end consumer comment is a good one.
As for to root or not root, I tell most people who ask me to root for them what they use their phone for and explain what they would get out of rooting, and explain the risks involved. Seems that people who understand what rooting does are able to do it themselves, and the ones that ask you to do it for them usually decide against it after hearing "there is a tiny chance that your phone could get bricked" lol

If you just want to play emulators etc, how would you benefit from rooting?

IMO rooting is very useful if you want to keep touching system things in a stock rom, optimizing and debloating it, installing other people ROMs, etc... I believe that if you compile your own flavour of android and find no restriction doing whatever you want, you don't need to.

Android phone without root is nothing

Some phones can just be flashed (for example via usb) which gives you full control, others can be cracked.

General question on changing ROM in device

Hi there,
Few months ago, I was told in XDA site that nowadays changing the ROM is not anymore the best way to de-google a device. Now it is better to de-bloat and tweak the device.
Do you agree with this statement?
Did you change the ROM in your device or only de-bloated it? Tell me your experience. Easy to install, need to root, unblock the bootloader, update, what is NOT working, speed, battery, ...?
I own a Samung Tablet S5e LTE few months old, under guaranty and would like to de-google it. I was thinking to change the ROM, is tit the best way?
What is your advice? If needed, what ROM to use? What way, software to de-bloat?
Many thanks

Fully agree with this.

Thank you for your fast answer.
Could you be more specific and tell me why, how (big picture) and if you have experience what tools did you use?

People most times use terms "De-google" and "De-bloat" not knowing what they are really speaking of.
The Vanilla Android ( read: AOSP - today often called GSI ) is totally free of apps developed by Google ( topic: GMS ) and the service ( GFS ) they need to run, this because NOBODY basically needs these to operate a phone. But the overwhelming majority of the users of mobile devices want an Android what is extended by features, so they can download & install more apps, play games, listen to music, watch porn videos. OEMs respect this wish - they want to sell their products - and therefore typically add GMS & GFS to their Android OS, so it in reality becomes a Custom ROM.
Resume: Vanilla Android - and all ROMS that are based on Vanilla Android ( like Lineage OS and many others ) must not get "De-googled".
Bloatware ( or Potentially Unwanted Programs - PUP ) is software users don’t want, that burdens and slows down a mobile device. It usually comes pre-installed by vendors, manufacturers or carriers. IMO "De-bloating" is the first thing a user should do when starting up a new device.
Bloatware typically is installed as system-app, hence phone's Android must got rooted before you can start "De-bloating".

As I am not very skilled in Android, I appreciate your post.
I installed LineageOS 17.1 on my Samsung S6, it working fine, I am happy for the usage but the only issue I have is that I can't update. This is another story in another XDA forum.
My need are usual plus
Read books, music sheets, social networks, Internet TV, news, training, conference (low bit-rate), email, messaging, GPS travel, basic pictures,
some specific app for music practice (tuner, metronome), veg gardening (I need to find one suitable for me).
but no game, no HD movie (download or stream), no large download
Backup locally (I need to learn more), no cloud usage.
As I run GNU/Linux for around 20 y, I hate to have to register for account in any app from GAFAM and I don't want as much as possible give them my data. I try to select the app without tracker, FOSS and I block the permissions as much as possible.
If I can de-google this is the best for my mindset.
I understand that de-google or de-bloat, I 'll have to root so break Knox. Right?
I don't know if I need GMS and/or GFS for my use. Could you tell me? For what app it is mandatory?
With my S5e I want to be more cautious, I need a way as secure as possible to not brick it.
With all these info, what do you advice?

For the Tab S5e de-googling it is next to impossible with stock samsung rom. LOS works great on it and not too difficult to install, CRDroid works well on it but is better with google installed, /e/ rom was being developed for it but I don't know if they are still working on it. I built an /e/ rom locally for my Tab S5e last year and it worked very well. If you want to get away from google you need to ditch the OneUI or whatever they are calling it.
