Hey guys, I acquired this phone and followed this tutorial to NETWORK UNLOCK it for free: https://forum.xda-developers.com/showthread.php?t=2024514
Then, installed CyanogenMod 13.1 (Android 6.0) on it. It runs extremely smoothly and everything is better than ever! Link to CM 13.1: https://forum.xda-developers.com/galaxy-s2-tmobile/development/rom-unofficial-cyanogenmod-13-0-hercules-t3246059
There's also Android 7.1.1 available that works smoothly, too. Link: https://forum.xda-developers.com/galaxy-s2-tmobile/development/rom-cyanogenmod-14-0-celox-t3470659
REN3G8, 15 Feb 2014love this phone, I've had it for a year and no issues to date... this page is wrong or outdate... moreI have same version 4.1.2 but I want to upgrade it plz if you can upgrade it then tell me my gmail is email@example.com
I've been using this phone since september 2012. I did NOT upgrade the OS, it's using Android 4.0.4. I honestly have zero complaints about this phone, I like that it does not have the physical button on the front for dirt to get caught in. It has the 4 "touch" buttons. It's now August 2015 and I still have absolutely no reason to upgrade. I'm not going to lie but this is probably the best smartphone ever made, if there is such a thing. It's seen it's share of abuse, I use a thin "adrema" black rubber case and it still has the factory screen protector on it(yes it came with a factory screen protector, unlike new stuff) and this phone has seen it's share of abuse. It's an outright champ. Unless you're playing demanding new-age games on your phone, you don't need anything more to this day. That's my two cents and I never write reviews for anything. That's how much this phone rocks.
Overall a great phone you can buy inexpensively, unlock it, root it, install a custom recovery, and now it will run everything up to Android 5.0 and work on all GSM & 3G networks worldwide. For a dual core 1.5Ghz device, it really does move quite well.
01101android, 25 Feb 2014Im running cm11 android 4.4.2 on mine and it is awesome!how to run that
Anonymous, 28 Nov 2013Does dis fone support video calling? can't find d video call option yes, but either through Skype or Google Chat
had this for over 2 years now, always been a great phone, but has recently been a very problematic device.
Running ICS 4.0.3, haven't been able to upgrade OS, in fact i haven't had a single OTA update since i got the phone and i have only ever been able to get Kies to work once (when i upgraded from Gingerbread).
It has served me well these two years and has out performed any other phone i have ever had, put its time to put it away and embrace my Nexus 5.
Anonymous, 24 Sep 2013I loved this phone! Everything worked great and the camera was awesome. Only flaw was the Blue... moreworks fine for me, have you upgraded the OS? I have jelly bean and works fine, I had issue with it when it still had ice cream sandwich, however that issue is gone after upgrade.
love this phone, I've had it for a year and no issues to date... this page is wrong or outdated, I have the Telus (Canada) version of this phone and I'm running Android 4.1.2 Jelly bean... so far very stable, I don't even think I'll upgrade yet until something I like comes out.
I am using this phone since February 2012 and I am in love with the perfection of this phone, everything works perfectly till date.
Love the Decent shape and Camera, also the Battery life is better than usual S2 sets, never faced any fault or malfunction and i use it 80% for WIFI internet.
the battery life is still pretty good and i am really a satisfied customer.
Y S, 23 Jan 2013Vol+ and power button didn't work for me on T989D.Does dis fone support video calling? can't find d video call option
I loved this phone! Everything worked great and the camera was awesome. Only flaw was the Bluetooth, to my knowledge, never worked... I only went to use it several months after I purchased the phone and the bluetooth wasn't working. it connected 2 or 3 times then stopped. My BF even changed the ROM in hopes it would help but it didn't... too bad. now im on the hunt for a new phone.
phone keeps going to emergency call, it was fine until lately, Sometimes have to resend text message. How can I boost signal to where it was
it has 4.1.2 as well now... and theres rumours that some of the s2 phones are getting 4.2.2 (this one was not mentioned). so for an android phone this one had the most major updates of any to date, from gingerbread to ice cream sandwich to jelly bean
