As the title states, the Galaxy Tab 4 8.0 doesn't seem to have a Screen-Mirroring feature. I believe it is also a 2014 edition too. I've checked the notifications tab when sliding down the screen, and there isn't any option to mirror my screen.

I've tried several third party apps as well, one being mira-cast which didn't help. I'd prefer not to root my device also.

Thank you!
[XDA Assist] Art Vanderlay:
Hi and welcome to XDA!

From what I read here I see that you have a SM-T230NU.

Tab 3 7 and Tab 4 7 don't have screen mirroring, only the 8.0 and 10.1 do.

The SM-T230NU model is indeed a Tab 4 7, so no screen mirroring for you on that tab.

Apologies for the late reply.

hey guys, i was trying to domestic unlock an sph-l720 galaxy s4. I followed a lot of different threads here and i felt like I was getting pretty close when i soft bricked my phone. My original modem was the L720VPUGOK3 (running lollipop 5.0.1), i used odin to flash the MDC modem. then (using odin) i rooted my phone. basically i got everything up until i started following this thread:

http://xdaforums.com/showthread.php?t=2530610

which, i got up to step 12) where it tells you to add the lines

ril.sales_code=LOL

ro.csc.sales_code=LOL

then when i tried to reboot, it got to the galaxy s4 screen then went black. usually after that screen it goes to a samsung screen then a sprint screen. I can hook it up to my comp and Odin will recognize it, but no matter what i flash (i've tried re-flashing MDC and root) nothing works. i can also boot it into download mode and recovery mode, i tried doing a factory reset, but that didn't help either. i now no longer have CWM though and so when i go to recovery boot i see this :

android system recovery <3e>

LRX22C.L720VPOGOH1

With the options

reboot now

apply update from ADB

apply update from external storage

apply update from cache

wipe data/factory reset

wipe cache partition

reboot to bootloader

power down

view recovery logs

enable cp logging

disable cp logging

and i am now lost as to what to do...

update: ok so after about 5 hrs of googling, i have managed to pull my build.prop file. oddly enough i didn't see the two lines i supposedly wrote.

i used build.prop.editor app from google play but i supposed i didn't know what i was doing and didn't actually write them in the first place. so now i'm really lost, since i don't know what my problem is. i'm also having trouble finding a build.prop file to download for cross-reference. any suggestions would be great

update2: ok, after a few more hrs of searching every forum and post i could find, i managed to flash a whole new rom (using odin) onto my s4 with the thought that if i coud just get my phone to reboot, then i could go through the system update over wifi, problem now is that i'm can't turn on wifi. i can press the button but it just goes straight back to off. And since i can't use my sim, i have no way of updating it to my original rom from the phone (which i'm still only guessing is possible). i couldn't find my original rom, so i guess i'll just keep flashing new ones til i find one that works. any suggestions would be appreciated.
[Samsung Galaxy S7 Questions and Answers] JovHok:
As a test I played 'NFS No Limits' in my Galaxy S7(Exynos) for about 20 min and I felt hotness all over the metal sides especially more in the area near power button. Also the back of the phone was a lot warm for touch. Is this expected from the S7 even with the heat elimination method inside. Below linked image is the results I recorded. Kindly take a look at the CPU temperature as well as the battery performance throughout the test.

https://drive.google.com/file/d/0B60MJrdiGFpZREM4enF5VVduUG8/view

Please note that Game Launcher optimizations were no used.

Is everything fine based on the above results?

PS: Even watching YouTube videos(in native app) for like 6 min makes the device a bit warm with CPU Temp to 34C from 30C(Idle state). Still normal?
[Samsung Galaxy S7 Questions and Answers] Blues fan:
I just bought mine this afternoon and it was a bit warm when loading the updates which I would expect is normal when downloading big software updates. Right now it feels normal.
[Samsung Galaxy S7 Questions and Answers] JovHok:
Well if you have time, please play and see how 'NFS No Limits' is on yours I see stuttering in game when there is rain. To measure CPU temp at regular intervals use this app https://play.google.com/store/apps/details?id=com.yanyan.cputemp
[Samsung Galaxy S7 Questions and Answers] wipeout207:
I repeated your test of NFS No Limits for 20 minutes using the CPU temperature app on a Galaxy S7 (Exynos). My results were similar:

Before test: 35C (it had heated up from 32C idle to install the game and app for the test)

At 7, 13, 17 and 20 minutes: 38C.

Battery before test: 35%

Battery after test 27%.

I also saw stuttering with the rain. The game was very smooth initially.

So very, very similar results.
[Samsung Galaxy S7 Questions and Answers] johanbiff:
ideal over 30c?? mine is under 27c...28-29c after 30min of browsing, yours seems defective or you are having rouge app thats using your cpu.

[Samsung Galaxy S7 Questions and Answers] chungdae:
38 is not that warm. My G906K would get up to 49 c while I was in the sauna and would not have a problem. If the phone gets too warm it will go into standby mode stating it needs to cool down
[Samsung Galaxy S7 Questions and Answers] ponkz:
Op location? Dubai? Room temp 30c ?
[Samsung Galaxy S7 Questions and Answers] KoRoZIV:
That app does not show real cpu temp...

at best what you have is battery temp.

And that was just because google services starter acting up ( from 9 to 15% usage in 10 min, consumed 6% battery ), no gaming or heavy use.
[Samsung Galaxy S7 Questions and Answers] dbux:
The therm_zoneX values are in no way related to CPU as far as I can see from these pics(attached).
[Samsung Galaxy S7 Questions and Answers] KoRoZIV:
The CPU is the hottest thing in the device; therm_zoneX reads are 75, normal for a CPU under load, therefore they indicate CPU temp.
[Sprint Samsung Galaxy S7 Questions & Answers] WeatherTech:
Is anybody with the S7 or S7 edge on Sprint having problems with various apps delivering push notifications late or not at all? I've noticed this specifically with apps like CNN and Reuters but also with a neighborhood app called "Nextdoor" that I use. I will get a notification about a message 10-15 minutes after I already received and checked it on the web version on my computer. I came from an S5 and never had anything like this before. Is this perhaps the power saving feature that suppresses background app activity? I would think it wouldn't do that for apps I very frequently use. No issues with text messaging notifications or anything directly related to the carrier.

Also - these have all been while on WiFi vs mobile data. It's really the only negative thing I've found so far. I am getting great battery life and standby drain.

Thanks!
[Sprint Samsung Galaxy S7 Questions & Answers] meyerweb:
I've noticed this only very rarely. For the most part push notifications come through instantly for me.
[Sprint Samsung Galaxy S7 Questions & Answers] Nextstep:
I think it has something to do with power saving feature, when enabled.

I was missing my Gmail notifications.
[Sprint Samsung Galaxy S7 Questions & Answers] WeatherTech:
It's happening really frequently for me. I will have to try adjusting my power saving functions.

Happening with a lot of apps for me - but mainly FB Messenger and Gmail. With FB Messenger the orange notification number on the app itself will display but I never get a sound/vibrate or notification bar notification. With Gmail it's like my email is not syncing but once every few hours instead of pushing notifications (my notification settings are fine).

I will have to try to mess around with the power saving function.
[Sprint Samsung Galaxy S7 Questions & Answers] hoodlum89:
Having the same issue S7. No notifications from WhatsApp, FB messenger etc. It seems like when the screen goes off it also turns internet off as each time I open the FB messenger it displays a message that it's connecting... not sure how to go from here :/ tried application manager options already
[Sprint Samsung Galaxy S7 Questions & Answers] ned4spd8874:
Yep, quite a few apps for me are affected. Using the stock settings for power settings, but I guess I'll have to play around to find which setting is causing this.

I checked and I have all power saving options disabled, so that can't be it...
[Sprint Samsung Galaxy S7 Questions & Answers] Nextstep:
If I have Power Saving on I miss all notifications until I open the specific app. Samsung changed it, hate it now I have to use my phone without Power Saving! :)

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] minionhunter:
Last July my note 12.2 crashed and I had to wipe and reset. I thought I had been saving my pictures to my card like my phone but I alas I had not. I was resigned after a month to do the reset, did so, rerooted, installed twrp and was just ready to get rolling again after so long without a tablet. However I read a great blog on imaging tablets and being able to recover many many files, found it plausible and could now go after my son's baby pictures and Christmas pictures. However I will need to install Linux on my computer and get that going again to do it and I've not been able to find a long weekend to do it without interruption by the kids. I just need to image it then I can take as long as I need to carve for the pics. I just can't get the time. It's been 8 months I've been without my tablet and it's starting to effect me negatively. So what do I do?

1. Beg my wife for the time to do the needed work to make the image. This would be difficult at best, and I'm understating that massively.

2. Try and find a new 12.2 64gb and use that till I get the time to image the old one. Expensive and I'm getting an old device.

3. Get a surface tablet, expensive and not android.

4. Get a new Samsung android tablet. New but I don't know what to get and if any newer ones can be rooted or have an SD card slot.

I'll take any and all suggestions of help.

Thank you in advance.

As the title says I am looking to make a 2.3 app work on 5.1, what should I be looking for when doing this?

Regards
[Android Studio] klisiecki:
Do you have any specific problems? An app made for Android 2.3 should work at 5.1 as well.

Of course you should consider updating app design, because it may not look very well on 5.1. Material Design for Android should be a good place to start.
[Android Studio] stickin:
Set targetSdkVersion in AndroidManifest.xml to the desired value (22 for 5.1).

Build your app with the updated SDK.

If you use some deprecated methods, lint should warn.
[Android Studio] Asmok78:
In android 5.0 some permission are changed. Eg. writing to an external SD requires use allowed directory, enable and disable mobile data and air mode need system permission (not allowed to normal app) etc.

In layout I found only one problem. Older androids recognize -1dp as match_parrent. (I'm not sure if it was changed exactly in 5.0)

I am trying to make a 2.3 app to work with 5.1, I use android studio but no matter what I do I always get non-exit error 0,1,2, no matter what I do, rebuilding the project, cleaning the project, udated the sdk, changed it, anything and I would not get past. The app is the default samsung music app from 2.3, I understand it needs touchwiz to work but before I can even see how to make it work I can't even go past this non-exit error. I have worked with android studio on another project and did not have this issue. Also, another music app winamp still uses the old 2.3 layout and it is fully functional on 5.1 so I know it can be done.
[Android Studio] stickin:
"finished with non-zero exit value"?

It can mean many things. Maybe you ran out of memory or exceeded 65k methods limit or there is something with libraries.

Isn't there something more specific written?
[Android Studio] johanos123:
This is the exact error:

[Galaxy Note 4 Q&A, Help & Troubleshooting] iSlaker:
I have a Galaxy Note 3 and a Galaxy Note 4. I encrypted them and it seemed to go smoothly on both phones.

However after boot, the Note 4 started giving me headaches.

Turning it on I see the usual CyanogenMod's animation for a few seconds then it jumps and disappears. then I see a white box saying Android is finishing booting, and then I'm presented with a pattern screen different than the one I used to see. This one lets me change the amount of dots. It also lets me make emergency calls. So I slide my pattern, I see "Checking" then it's just the same initial CyanogenMod animation. For ever.

With the Note 3 I saw the exact same thing but the second animation lasted just a few seconds. Now it is working fine. The Note 3's storage had around 100MB in data. The Note 4 has several gigabytes of data in it. I presumed it was still doing some work, so I left it in the animation screen for a few hours. When I touched it was burning hot.

It won't enter Recovery Mode. I tried flashing recoveries with both Odin and Heimdall. With Odin it seems to work but it won't boot into Recovery Mode. Heimdall always gives me an error. I tried flashing cm-12.1-20160316-NIGHTLY-trltexx-recovery.img, twrp-2.8.7.0-trltexx.img and twrp-3.0.0-0-trltexx.img with Heimdall and twrp-2.8.7.0-treltexx.img.tar and twrp-3.0.0-0-treltexx-treltexx.img.tar with Odin.

Update: I've managed to install TWRP 3.0. The problem still persists though. TWRP doesn't ask for password or pattern, which doesn't allow me to do pretty much anything. The only MicroSD card I have is only 256MB - usable 240MB - latest CM 12.1 nightly is 255MB - so I can't even flash a new ROM! I'm surprised TWRP doesn't have a way to decrypt the storage. I very much hope I'm missing something.

Update 2: I've managed to flash a few different ROMs via ADB Sideload. I still can't get access to the data partition at all. I can't even format it! I'm getting quite desperate at this point.

Please, help!

I flashed a stock ROM. I genuinely thought it would completely erase the entire phone memory, but it didn't. as soon as it finished booting I saw the pattern decryption screen, but it just wouldn't accept my pattern.

I flashed another TWRP 3 again, went to that scary screen and wiped, and formatted, and erased, and did everything it allowed me to do, as I was sick and tired of that drama. flashed some CM to it and was done with it.

never trying to encrypt that thing again. Android's openness is too chaotic: too many OS variants, too many vendors, too many minor model variations, too many non-standard stuff going on. the result is it's unlikely someone else will have the exact same problem, with the same model, the same OS. I'm done.

I got the international S7 Edge (935f) and I am using it on ATT.

The ebay sellers remove the region lock before shipping, which requires a 10 minute call in the originating country. I also had no issues when putting my ATT sim in and didn't have to change APN settings or anything, it all worked immediately. I get 4G LTE and speeds are typical for what I am used to. I could also use my phone as a wireless hotspot right away, which was very important to me, and something ATT does not allow without a separate plan. No band 30 as was mentioned, but I can live without that. Also, no samsung pay (for the time being), and no voice over LTE, which I never used before anyway. You're also on your own for warranty.

Not many disadvantages to taking the international over the carrier brand, and you will get a lower cost, bloat free, and rootable/fully customizable phone as an advantage. Very happy w/ my purchase.
[Samsung Galaxy S7 Guides, News, & Discussion] ChristopherXDA:
I'm curious if the Samsung Pay app is missing or if it's present and just unable to be configured due to the model number. Thanks! Also, I read someone complaining about GPS with their SM-G935F here in the US. Can't imagine why that would be, but have you had any issues in that area?
[Samsung Galaxy S7 Guides, News, & Discussion] Hisma:
samsung pay is not even present. It needs to be baked in by the carrier.

As for GPS, it's perfectly fine. I used it earlier today and it locked in & got me where I needed to go without issue. I don't see why people would say GPS would be impacted by an international phone? GPS will be the same in all of these, and it will connect to the same satellites all the other carriers would use. This isn't like a car where it needs to have region-specific maps pre-loaded.

[Samsung Galaxy S7 Guides, News, & Discussion] N-way:
Call AT&T support and give them your IMEI.. they will update it for you in a few seconds.

It won't really make any difference as the SM-G930F is not certified for AT&T's HD Calling. Other than that it works fine on AT&T.

LTE works well, using the ATT Nextgenphone APN settings.

Anyone tried using AT&T CSC on the Exynos variant?

I assume that it would also mean you can't use OTA anymore and will need to manually update every time (correct me if I'm mistaken)

The reason why I ask is that I looked inside the AT&T CSC package and it contains several Qualcomm APKs which obviously would not work on the Exynos hardware.

If you flash the AT&T CSC the international variant would you be able to get HD Calling (VoLTE)?

[Samsung Galaxy S7 Guides, News, & Discussion] purposelycryptic:
I have an S7 Edge International (G935FD), and while so far it works flawlessly on AT&T (4g, GPS, etc), Samsung Pay does not work (at least for me).

It did not come pre-installed, nor can you download it from the play store, and, although after installing the APK's from APKMirror (Samsung Pay & Samsung Pay Framework) and manually setting the permissions, I can get it to run, it will not recognize fingerprints (Have to create a pin), and when trying to register a card, it throws a "Can't connect to Server" error, so its functionality is zero.

Since Samsung Pay is linked to your Samsung account, and you can't register the international version of the phone on a US account (Its supposed to auto-register when you first log in on your phone during setup), it may never work properly (Assuming it checks the IMEI against those registered to your account as part of authorization).

I hope someone figures out a way, but I'm not exactly hopeful at this point:(
