Hi. yes, it's possible to install a clean OS without Google-Stuff but ur phone must be rooted.
here is a good instruction http://www.beritahuaja.com/2015/10/how-to-root-samsung-galaxy-j2-sm-j200.html
If you do have done, you can uninstall the Google stuff. If you have no idea what you should do there, let it be.

I have CyanogenMod | Android Community Operating System installed on my phone (an "old" ZTE Blade) and it works just fine, it was a bit complicated installing it, but there are plenty of people posting tutorials and other information on how to proceed. However, I think your phone is still "too recent" to have an alternative OS available for it, at least for CyanogenMod -devices... Unofficial Ports - CyanogenMod , you should probably check these links once in a while, and maybe post a request here .
Meanwhile find out about "rooting" your phone. After you "root" your phone, you'll at least be able to get rid and block some of google's junk.

some way to install "alongside"? like install a second OS on the sd card?

Puedes intentar instalar replicant aunque es algo complicado. O descargar kingroot para rootear tu teléfono y poder desinstalar esas aplicaciones de fábrica que no quieres. Finalmente si lo anterior no funciona solo queda inhabilitar las aplicaciones.

maybe u try to uninstall or disable with F-Droid (search them on the net or on github) disabling manager?
dress for success :-)

.. i'm kinda on an outpost, kinda marcian .. not going to risk much .. if you never hear from me again it's because i screwed it up ..

kingroot.net try with this rooter, it just take a few minutes to root your device. Then uninstall those google apps. Fast and easy!

@ʕ•ﻌ•ʔ jeSuisatire RequêtéChe cc0-NC How is life with a rooted smartphone? at least made it and got rid of the googl*ey*?

If you managed to get it "rooted" but still can't install a different OS, you may find the following apps interesting (some will help you escape some of google's crap), you will have to install F-Droid – Free and Open Source Android App Repository to get them.

busybox (needed for some of the others)
systemappmover (a go-around to disable some stuff)
Disable Manager
AFWall+
OS Monitor
AdAway
Cache Cleaner
GApps Browser

Most of these need "root". The "Disable Manager" app works without "root" and will allow you to stop some of google's apps from running in the background. F-Droid is probably the safest place to get apps.
I'm not an authorithy on the subject but I hope these help. Make sure to read the info on the apps.

do not cry about it, but always look at the brightside of life...

well, to be sincere i only managed to read the link daniel posted and am trying right now to wrap my had around this new toy.
So you cant just .. #su .. password .. and be the owner of your life?
very disapointing!
i expected more ..

thaaan .. to root from the outside or to install another f** program that might hack you .. to be or to do .. that's the question ..

seriously guys, i apreciate your help and efforts .. but actually yesterday nearly literally while reading this post my debeian jessie just killed itself while i was doing some movie rendering and starting skype .. like to say .. the skype troyan has so many bugs that i guess i will first fill out those reports before i throw myself into more trouble .. :(

understood. let us know, when u find the nerves to deal with it.

:)
thx for the comprehensive insights and tips to all!

looks like it wasn't the skype-horse but the "disk-full security breach" .. :)

now at least i have access to the phone, debian wheezy is a pane to impossible .. :(

ok .. i started by digging into #fdroid .. it's kinda linux/github compared to google that fels like microsoft. i like it .. i will start to clean up without routing and see to witch extent that is possible i guess .. :)

you're not obliged to open a google account, even on android. But use other appstores than googleplay like aptoide or fdroid

@shonpolo@framasphere.org Be very carful, which way u order ur flights with considering departing between France-Birmingham and Berlin. Don't let the app read ur system-supply.

@yourWay : what do you mean by system-supply ?

@shonP as NOtek I do prefer easy going with programming and routing, that's why, when not my own system and progs in use I relying on the devicesfirmware, which can be manipulated by the connect to the different "shops", when registering to the net by ident-email. That's why I disconnect during installation and reset, and then put anti-theft and register with that to the net. My thought: it'll be unable to read my passwd.
Ahblablabla. Where and why are u asking?
