[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] hytl:
Thank to you you guys. I installed the U firmware with the Tmobile CP file on my phone. It's running smoothly but Android System is killing my battery. What package/apps do you guys disable/uninstall? How do you guys optimize your phone? Thanks

PS: I followed the guide from AT&T S7E thread

"How to install:

Put your phone in download mode.

I personally had success with this version of Odin: http://www.mediafire.com/download/2t...din_3.12.3.rar

However another user couldn’t get it to work and used this version: http://d-h.st/gsDA

Flash the 4 files in this zip to your phone using Odin. All 4 of them: https://www.mediafire.com/?fm3oxddajta1k07

Put the BL in the BL slot, AP in it's slot, and so on. Flash all 4 at once through Odin."

Let the phone settle for a couple of days. Mine did the same for several days and now is good to go.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
If I flash this firmware and then do the root method will this firmware have that same lag issue etc with the eng bootloader?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] noobiedev83:
Yes! to be honest this root is garbage, we need a better method!
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Hm I see. How come the guy earlier in the thread on the first page was saying how he had like no lag when flashing the u firmware and then doing root? I'm asking because I don't wanna flash for no reason and have to start all over again
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] noobiedev83:
This rom is faster than the t-mobile version but the root still makes the phone lag,so I said yes for the rom no for the root!
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Yes I know that part but he said the eng bootloader after root did not have that lag effect after root on this u firmware when compared to doing the same root on the previous firmware that's why I'm confused.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] noobiedev83:
Is the same thing man!!
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Sigh.. Ok. Good thing I didn't flash the u firmware then.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] noobiedev83:
U firmware is better! But not root
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Ok I don't really have the lag issue much since I installed l speed and did the cpu governor adjustments and all that. Does this firmware have the same YouTube app issue when you play a 60fps video and the video freezes sometimes but audio continues?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] blane3298:
install sEFix and set it to the highest setting. Speeds things way up
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Yeah I did all that stuff already but noticed that even people without root have that same YouTube app problem as me
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] crashnova:
Does this last link include the TMO CP file?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] hytl:
No, it doesn't include the Tmobile CP. You have to go back 1,2 page to download the Tmobile CP someone posted in this thread.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] noobiedev83:
Wait you can't use the modded Odin?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] Compusmurf:
I know using ODIN to reflash the SAME rom doesn't wipe data. EX Tmob pia to Tmob pia, what happens when you do odin PI3 over PIA? Does this wipe your data?

I have a customized work app I really don't want to have to reinstall and reregister.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Question to people that flashed this firmware.. Any of you root afterwards and still get smooth performance or is it the same slight lag issue after adjusting cpu governor and all that?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] frostwildfire:
Can anyone confirm if flashing the FW 935u sim unlocks the phone? TIA
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] frostwildfire:
It hangs a little during boot but after is smooth, I prefer stock is smoother enough for me.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] b0ricuaguerrero:
quoted from greenman, over at sammobile forums

"If you place the "normal" CSC-file in the CSC-slot in Odin, your device will be "wiped" and you'll get a phone as "out of the box"

If you place the "HOME_CSC"-file in the CSC-slot, your device will NOT be wiped and the data is preserved on your device (as in the 1-file update in previous devices)

That's the difference between those files."

[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] Compusmurf:
Thanks. Learned something new today! Mind has been expanded.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Hm Ok. So it is smoother than the tmobile firmware with the same root method with the engineer kernel?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] frostwildfire:
It is to me, I play games and run great, facebook, whatsapp are fast. The root is up to you mate, for me stock is enough.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Uh :-/ it's like no one has rooted with this firmware for me to get a firm answer
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] blane3298:
ive rooted it a few times. its smoother but the battery life still sucks
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] b0ricuaguerrero:
so...... i personally tried flashing the u firmware. loaded all files into modded odin 3.12.3. flash through odin was successful, reboots to recovery and get the "dm-verity need to check verification failed" error. I tried wiping cache and factory reset with no luck. even tried just flashing the ap file over the tmo-pia firmware. same thing. any suggestions?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] nitroevo:
Does volte work and do you have any heat issues etc..and also how much smoother is it?
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] blane3298:
i didnt check volte to be honest. it still gets hot and its a tad bit smoother
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] frostwildfire:
Did you placed HOME_CSC file at the CSC space? I did that and rebooted to recovery too, I flashed again all files but this time selected the CSC file instead HOME_CSC and booted without problem.

I did mine yesterday with the files and odin found in the thread and had no problems. I even restored with smart switch and got everything back. The only thing that I miss from the T-mobile firmware is the wifi calling, this firmware doesn't have it.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] purotijuana:
Lol hahahahaha i was just saying. Whenever you want to try ROMS and then back to stock, u have to go back to latest original stock
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] cruel91:
It does have. Check your phone app settings
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] DreamCrusher:
Open phone app. Then tap on "MORE" in the top right corner. Select "SETTINGS". Scroll down and you should find "Wi-Fi calling ".
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] cral:
Thanks guys, I found it, but it won't connect, keep getting error 081. I rebooted the phone and the router and nothing.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] cruel91:
I also have that error sometime, but it just vanishes as it comes

Can anyone help me out or shout out if there is any chance to install SuperSU or Root without PC/cmd?

Things I have lost that I noticed since flashing the u firmware is fm radio capability as well as the ability to make video call from dial pad

Hi could i just flash this straight from being on the echoe rom seeing that it is the same pia?

I have been using the U firmware for 2 cycles. Battery life has been amazing.
[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] kdecoteau1:
Hey all. Only thing is no video calling, text messages works great. Best to be on APIA before FLASHING API3 U firmware. I used a MODIFIED PDA+ apk for MOBILE HOTSPOT, it works EXCELLENT as I can see. This is the BEST STOCK OFFICIAL FIRMWARE ON ANY US SAMSUNG GALAXY PHONES I EVERY USED.

OVERALL PERFORMANCE IS GREAT, I HAVE ZERO PROBLEMS.I will RECOMMEND

---------- Post added at 06:19 PM ---------- Previous post was at 06:12 PM ----------

The G935U STOCK OFFICIAL FIRMWARE IS EXCELLENT ON T-MOBILE G935T phone, BEST PERFORMANCE STOCK FIRMWARE I EVER USED ON ANY US SAMSUNG GALAXY PHONES BY FAR. I HAVE ZERO PROBLEMS WITH THIS ROM, will RECOMMEND to anyone who wants it.

---------- Post added at 06:35 PM ---------- Previous post was at 06:19 PM ----------

This G935U FIRMWARE also FREE UP 2.3 GB OF INTERNAL STORAGE ON THE G935T MODELS.

MY PHONE DOESN'T RUN THAT HOT ANYMORE, that was one of my PROBLEM WITH SNAPDRAGON PROCESSOR THEY RUN HOT ?, Sometimes I have to put my PHONE IN FRONT OF A FAN TO COOL DOWN. One time I was using the MSNBC APP and the phone got EXTREMELY HOT, I put the phones OUTSIDE FOR 30 minutes. I RECOMMEND the U firmware once you don't mind LOSING THE VIDEO CALL feature.

---------- Post added at 12:15 PM ---------- Previous post was at 12:02 PM ----------

Is there a site that lets you download the firmware fast? 6 hours is a long time from this site since they want me to pay like 8 bucks to get full speed..

Here are links (from earlier in this thread) to download the U firmware and also the tmobile CP (modem) through odin.

Wow. Flashed th3 U firmware last night. It's a total night and day difference in performance! I was rooted on echoe rom and I will be staying stock until a new root method is found or I upgrade to a new device. I can live without root on this device simply because stock out performs the hell out of any rooted options we have including stock rooted. Just my 2 cents :)

I must say I have rooted on stock SM-G935T and it was quite laggy and also the heat was bad. I installed SM-G935U and stock batter life was phenomenal. I decided to root and it the root is running flawlessly. I am getting great battery life and no lag what so ever. SO if anyone is considering rooting, I say go for it. I am enjoying it without issues.

hey... did you guys rooted the SM-G935U using the same method as for the SM-G935T? If you did, is anyone having the "unfortunately IMS service has stopped" error when making phone calls. I would like to know before i try to root again. and if you don't get the message what method did you use?

Thanks in advance.

For those that are saying that video calling does not work for the U firmware, I use video calling with my wife quite often. You have to ensure that the Volte setting is turned on. Once you make a call and both of your carriers allow video calling a green video camera will show up just like with stock firmware. Just tap that and it will switch to video calling as long as the other person accepts the request. Both me and my wife are on T-mobile. So video calling is authorized on their network.

[Galaxy Note II Q&A, Help & Troubleshooting] FeitXX:
Greetings,

I recently bought a used Note II and that the seller had already informed me of this problem but I can't seem to figure it out;

Input on the mic and output on the earpiece doesn't seem to work during phone calls. Though any other app isn't affected by this. Apps that had been tested are: Messenger (Facebook), Camera, and Snapchat all are working flawlessly except for the Phone app. And here's a more "bizarre" scenario, any other ROM that I install or Factory Reset that I do retains this problem, even Stock ROMs are affected by this.

And sort or form of help is greatly appreciated :).

Hi,

I'm a noob and my english is not great. I read the Android documentation provided by Google but I'm still wondering what Activities, Services and BroadCast receivers are. Are they classes (subclasses of Activity, Service, BroadCastReceiver), are they the objects we get from instantiating the classes, are they something else?

Thank you for your answers.

PS: Sorry if this is not the appropriate forum
[General Questions and Answers] GenieKnudson:
Re:

If you are new to android, do not get confused with anything. Let me explain with a newbie touch.

If a code is running in background it is service.

If a code is communicating with all the apps to and forth, it is broadcasting.

Rest lie in activity category(with few exceptions).

If you are looking forward to learn android, start with building a simple application which only use activity. After you are done, add more activities. After that try to add services and broadcast messages. This way, you will not get confused in any way and will able to learn more(if you proceed with only learning individual tutorials).
