Hello,

I've just installed the latest CM13 espressowifi on my 5110. Auto brightess doesn't work. I see that there is a mod kernel for that but it's only for the 3100. Any other has the same issue on a 5110?

Thank you.

Update:

After a reboot now it's working.

Thank you Andi, your CM13 give to my tab 2 a new life! It was unusable with the stock 4.2.2 Samsung firmware.

Hi, I have a little problem: the WiFi connection during all online games session, after 3 or 4 minutes, disconnects and reconnects instantly, so the game kicks me out and must reload the game session... It's really frustrating for me... I have just tried to reset to default the network setting... Only this tablet with all WiFi connection have this problem, how can I resolve? Sorry for bad English

As far as I know at least 5100 does not support 5Ghz. Probably the same for the other tablets?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
Using google search, sometimes it's mentioned to have dual band wifi and i remember some user told they have it working. Maybe it's an country specific feature or only on p3113 or p5113 available?

Support for it removed on latest build, I'll add it back once i have a confirmation for 5ghz variants.

I might have something i can add next time for testing.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] BoneWithABeagle:
That was me, and at the time we discussed it (was it Lolipop or already Marshmellow?), it worked.

The problems were:

- Android screws up when the access point / router is set to _not_ broadcast itself. Even when you manually enter the SSID Android doesn't want to connect to the "invisible" AP. Allowing the AP to broadcast itself resolved the problem.

- Android gets confused when both WiFi have the same SSID ... having a different name for the 2.4 and 5GHz spectrum was the solution to the problem.

That being said, I just pulled one of the 3110's I have sitting about collecting dust out and flashed the latest CM13.0 ROM + AnyKernel (was still on a CM13 build from July '16).

No Go with 5GHz, doesn't even see the access point.

Restored the 20160702-1234 TWRP backup and 5GHz works again.

So, whatever the problem, you seem to have introduced it at some point after the 20160702 build.

EDIT: Just as a "food for thoughts", maybe something to do with your revamped kernel? If I'm not mistaken the July build isn't based on your kernel-cleanup sources.

Hi! Sorry to ask, but am I using the right gapps package? "open_gapps-arm-6.0-nano-20161103" is the file name I downloaded on opengapps.

I also downloaded "gapps-601-base-20161103-1-signed.zip".

The situation is, I flashed rom (oct30), flashed "open_gapps-arm-6.0-nano-20161103", then reboot.

It rebooted ok but gapps shows crashing too many messagebox popping up.

Then I reflashed rom, then I flashed "gapps-601-base-20161103-1-signed.zip", it shows an error of --

` set_metadata_recursive: some changes failed `

`E:Error in /external_sd/gapps-601-base-20161103-1-signed.zip

(status 7)

Installation aborted.

After this I tried to reflash the first gapps I tried and it says incompatible version of gapps installed.

Please can anyone tell me what am I done wrong, thank you

Hi, not sure if this has already been asked, but does anyone know if using a dedicated microsd card for internal storage has any noticeable performance benefits? Is this even possible on the CM 13 Rom, in particular with a microsdHC or microsdXC card?

If so, how does the read/write speed of the fastest SD cards (UHS 1 and UHS 3) compare to the tablet's native storage speed? I've noticed that the tablet is a bit sluggish with CM 13 (even with Greenify auto hibernating most apps). Would a microsd card help boost performance at all, or is it for the sole purpose of expanding storage with no additional benefits?

Also, just to confirm, after adding the SD card, would the transfer / setup be done automatically, or would I have to reflash anything (TWRP, CM 13, etc)? Is all settings, apps, and app data preserved? Is it compatible with encryption / root? Lastly, would anything change for flashing updates to the CM 13 Rom and TWRP?

- using Samsung Galaxy Tab 2 10.1, P5113.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] jasxyhen:
Im sorry sir Andi. But now I have a different issue. I use your posted recovery, and tried to reflash rom and gapps. It results in bootloop. I tried to flash rom only, without gapps. And the rom is successfully flashed and booted. Can you please help me?

The gapps I used is open_gapps-arm-6.0-nano-20161103.

Again Im sorry, and thank you.

Why you require screen cast for chromecast? To view photo/video or youtube videos on TV, third party apps like All Connections from PlayStore can be installed. Its working perfectly as screen cast.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Dr.Fix:
Because I need to stream the whole screen.

There are some streaming applications which shows videos in a format which is not supported by chromecast or that don't have the "send to chromecast" feature.

At the moment I'm doing it with Omni, but I really prefer Cyanogen.

Greetings,

I just wanted to report that the "Screen Mirroring" or "Cast Screen" feature is working on the latest build (with the recommended changes to media_codecs.xml).

Device: P5113

Recovery: espresso-common_TWRP_3.0.2-7.zip (performed wipe as described here: https://andi34.github.io/faq/faq_twrp.html).

ROM: cm-13.0-20161106-1214-UNOFFICIAL-espressowifi.zip

GApps: open_gapps-arm-6.0-pico-20161104.zip

Installation of ROM+GApps was performed as described here: https://andi34.github.io/faq.html (How to flash a Rom properly?).

I can also confirm that both Video recording (from the Camera App) and "Screen Mirroring" are working on your latest OmniROM as well.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Andromeda_Station:
Sorry, maybe I didn't word that right...what I meant was, to the best of my knowledge casting in Android is only implemented for Chromecast devices. From your post I think you are trying to cast to a smart TV? Unless I'm mistaken, casting to a Miracast/UPnP/DLNA device will always require a 3rd party app. Unless you are using Chromecast, in which case ignore me :o
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
I do not have a mircast device, nothing i can test. I am not sure if the aosp cast is made for miracast...

Can you see the device in the cast list? If yes, try to connect and take a logcat while doing it.

If the device/tv not available in the list, nothing i can do for you.

Edit:

Just as information: it might take some days (next sunday?) until first official CM builds shows up, CM switched to weekly releases on CM13.
