P905 successor

Hi

It seems that Samsung has finally made the successor for the P905, the Samsung Galaxy Tab S7+

It's a beast of a tablet, 12.4" Amoled screen, latest SD865+ processor, 6GB ram and 128Gbyte storage

Only downside i can see is that it is VERY expensive.

$1000 for the wifi only version and even more, for a 5G enabled version.

I would be tempted to buy it if it was to come down a bit in price, my P905 is beginning to show signs of age.

More specifically it has begun sometimes to run very slowly for a period of time, making it not very usable. Have tried taking the back plate off, pulling the battery connector to do a real cold boot, and also tried installing the latest version and doing a full wipe and new setup from scratch without it helping.

I am thinking of trying, going back to android 9 to see if this will relieve some stress on the tablet, but i am not too optimistic.
[Galaxy Note Pro 12.2 Android Development] JaWilfe:
I think the same about S7+, it is the sucessor for P905. But I have the same issue that you told: the price is very expensive ( I'm brazilian and here the price will be like RS 8.000, 9.000)

About the problem with run slowly for a period of time, mine has the same issues some tames. But i just need to reboot to everything be alright. I just use like a notebook in college and see some movies, surf in the internet, etc.
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Yeah and here, when you add VAT the price is more like $1175 so really expensive.

I think i will wait and see, if the price will drop.

Mine does not recover just by rebooting it sadly. Sometimes when it is slow, i dont use it for a few days, but keep it turned on and on the charger, and then it will be just fine the next time i use it.

Another thing that makes me think not to buy it, is the experience of the samsung P905 android updates.

Mine was born with android 4.4, it was upgraded to 5.1 by samsung and then promptly dropped and it never received another update.

Had it not been for Valera1978 it would probably be on 5.1.

I am afraid that Samsung will do the same here....Release the tablet, release one major update, conclude that the sales did not go as well as expected, and then promptly drop it from future updates.

At that point i will be totally dependent again, on someone like valera1978 to continue updating the firmware whenever a new android version is released.

Samsung did not even release that many security updates either, i would not mind being stuck on an android version a couple of versions back, not that much has happened from 8 to 10 for example, but having a tablet that is a few years behind on security updates is a big problem for me.
[Galaxy Note Pro 12.2 Android Development] jed84:
Samsung officially announced that they will release the total number of 3 major Android updates for Tab S7 series and Tab S6.
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Which is really great offcourse, but if that is

Born with 10, will get 11 and next year it will get 12 and then it is finished, it is still a bit poor, as they usually sell these specialist tablets for atleast a couple of years.

I bought my P905 on sale in the summer of 2015, at that time they had already upgraded it from 4.4 to 5.1....It had 4.4 from the store, but 1 hour after i got it, it had the 5.1

So if i buy the S7+ next year, it will only have 1 real update, as they might already have updated to 11.

I dont understand why it is that Samsung would only do 4.4 to 5.1, but one single guy was able to make Android 6, 7, 8, 9 and 10 available for the same tablet.

If Valera1978 or someone as clever as him, gets one of the S7+, they will maybe keep it alive, but for a $1000 tablet, i would expect it to last more than 2 years and to make Samsung responsible for this.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
All what you said is IMO right and that's the reason why I don't buy any new samsung devices any longer.

I wait 2 or more years, look if a dev is supporting which and then buy it used.

I'ld rather give the dev some money than pay Samsung the whole lot.

My P900 (bought with the age of 4) has not even the need of a new battery although it's from 2014.
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Yeah, as long as my P905 works, i am not going to shell out in the region of $1000 for a new one.

Especially after the let down from Samsung with the poor update lenght of the P905

I know that it cost money to take a new version of android and making it work on a specific hardware, but samsung also makes it really difficult for themselves, because they do so much costumisation and put in so much bloatware.

I have no doubt the S7+ has a lot of processing power to cope with all of the bloatware they install on it, but i remember when i installed CyanogenMod android 6 om my P905, it was like getting a whole new and faster tablet. I can not understand why they would bog the P905 down with so much...essentially crapware.

What they did was give me a reasonably powerfull car, but then strap a trailer filled with junk to the hook, making the car a lot slower and harder to drive.

Have never owned a samsung phone but from what i hear, they also pile on the junk on those.
[Galaxy Note Pro 12.2 Android Development] 94b20gsr:
So, I saw it asked a couple of times with no clarity. Is it possible to use this ROM on a P907A? I've got one with 5.1.1 that I've had since new and would love to breathe new life into it if possible.

[Galaxy Note Pro 12.2 Android Development] 94b20gsr:
Thanks.... But all LTE models have the Snapdragon 800 meaning the 905/905v/907a. That part I've got. I am wondering if it is possible to unlock the bootloader on the 907a and if there are any drivers specific to it that would be an issue if software for the 905 are loaded onto it. Here is a link to a much better comparison of all versions of the 12.2": http://phonedb.net/index.php?m=device&s=compare&ids=6057.6569.5237.5281.5300.5604

Sorry I've mangled up 900 and 905.
[Galaxy Note Pro 12.2 Android Development] mojoe:
Been using this software and others from dev for over 5 years. Great and Thank You.

My device is P905, your software version 20200815.

Wifi Direct not working and USB connection reboots if I choose File Transfer.

Please advise.

Although 17.1 supports Korean language, it is a little inconvenient because Korean keyboard cannot be found even with keyboard settings. Is there any way to add a Korean keyboard?
[Galaxy Note Pro 12.2 Android Development] alantay11:
You'll have to install a 3rd party keyboard. Gboard is the most similar to the stock one.
[Galaxy Note Pro 12.2 Android Development] shardsx:
One method to have working USB connection is to enable Developer Options. In the Developer Options you will find "Default USB configuration". Change the option in here to File Transfer before plugging in your tablet to a computer. This avoids the crash.
[Galaxy Note Pro 12.2 Android Development] mojoe:
Thank you. Appreciated. It worked.

Does this mean that every time I want to use USB connection I have to go "Default USB configuration" and change the option to File Transfer?

Is there no way it can be kept on permanent to File Transfer.
[Galaxy Note Pro 12.2 Android Development] mad0701:
Yesterday it wasn't possible to establish an adb connection. No toast popup for authentication / fingerprint. Adb didn't detect any device.

I have updated adb (1.43) all drivers (adb and Samsung) nothing happen via USB.

Adb over network see the decive but if I try to make anything, the message device offline was all the time visible. Nothing help. I Downgrade to an image with 5.02.ADB is working without any issues.

So I believe that there's more as only a small bug with USB

Hi I tried the build: lineage-17.1-20200815-UNOFFICIAL-viennalte

There is no palm rejection...
[Galaxy Note Pro 12.2 Android Development] shardsx:
Valera1987's official unofficial build from August does not contain the fix for palm rejection. You need to download Ahgoo2020's build from post #225, which has the fix. Ahgoo based his build off Valera's code with just the S-Pen palm rejection code modifications.
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Crossing my fingers that the "missing" updates for the last 2 months, are because Valera1978 is working to get Android 11 working on the P905.

I feel Samsung owe him quite a large wad of cash, for his continued support of the device that THEY should themselves have supported...For way longer than 4.4 -> 5.1 ... And then goodbye
[Galaxy Note Pro 12.2 Android Development] High#5:
... or he moved on to the S7+
[Galaxy Note Pro 12.2 Android Development] onoffitalia:
i downloaded and installed your update with this fix, thanks for offer this work done but I cannot find any difference with original rom, how test if palm ejection working correctly? thank you!

+1
[Galaxy Note Pro 12.2 Android Development] shardsx:
Speaking on behalf of Ahgoo2020, palm rejection can be tested using any application that allows you to draw or write.

In the ROMs where palm rejection is not working properly, start drawing a line with the S-Pen. While the pen is still in contact with the screen, using your finger touch somewhere else on the screen. With malfunctioning palm rejection, the line being drawn with the S-Pen will disappear, and the touch event with the finger will register instead.

In the ROMs where palm rejection is working properly, start drawing a line with the S-Pen. While the pen is still in contact with the screen, using your finger touch somewhere else on the screen. With working palm rejection, the touch event with the finger will not register or interfere with the S-Pen input in any way.

For as long as developer options is enabled and the Default USB Configuration changed to the File Transfer option, this is permanent.

If you don't want to enable developer options on a permanent basis, but have root access, there is a way to modify the default.prop and build.prop files to force File Transfer permanently.

In default.prop, remove the line persist.sys.usb.config=adb

In build.prop, add the line (or modify the value if the line already exists):

sys.usb.config=mtp

sys.usb.state=mtp

after installing image and gapps my device keeps rebooting into TWRP

Hello, I installed TWRP, wiped all, installed the image from August patch, then installed the gapps and the devices rebooted to system. After waiting with the "animation" for some time the device reboots again in TWRP. Then I tried to do it again but my device still reboots into TWRP. What can I do? Please help!
[Galaxy Note Pro 12.2 Android Development] Antoneeo:
I understood the problem..

To recover I used Odin with official release and it recovered.

Then I installed TWRP and the Lineage 17.1 and it worked!

Then I tried to install google apps but it said that there was a size problem with System.. I did what I found in another thread here at XDA:go to wipe/advanced and then select system and did resize and restore.

At this point it was possible to install the stock gapps but it could not fully boot again (minutes on Lineage animation then reboot to TWRP). So obviously the problem is installing stock gapps resizing the system partition.

I will recover all again but I will try to install the "pico" version of gapps
[Galaxy Note Pro 12.2 Android Development] mad0701:
Use the Gapps Nano.
[Galaxy Note Pro 12.2 Android Development] Antoneeo:
Thanks, the "micro" worked fine.

After all, when I tried to install Netflix I found that the SELinux not enforced of this release does not allow to use Netflix..

I found that the Android 9.0 version is SELinux Enforced and installed it (another user pointed out).

Would it be possible to have Android 10 built with SELinux Enforced? This would be great!

Thank You!
[Galaxy Note Pro 12.2 Android Development] mad0701:
With lower version of Android, the Netflix version works, which is available directly on the HP of Netflix (in the help sector, Netflix doesn't work) In Android 10 you must fry different version from APKpure. Some version are working, some not.
[Galaxy Note Pro 12.2 Android Development] Antoneeo:
Yeah! I am trying Lineage OS 16.0 Android 9.0 and Netflix works but unfortunately the microphone does not work with Skype and Zoom.. I am giving up and going back to stock release. Before I return to stock there is any new build with fix coming?

Thanks!
[Galaxy Note Pro 12.2 Android Development] mad0701:
The microphone bug I've reported a long time ago.
[Galaxy Note Pro 12.2 Android Development] spectre.laser97:
So, does this ROM support signature spoofing? I know that the default Lineage OS does not support it but it may be added by the dev of this ROM. If not, does anyone tried the Xposed Signature spoofing module or nanodroid patch with this ROM?
[Galaxy Note Pro 12.2 Android Development] Ralinde:
This is my first post here and I just want to give thank you to all this community. Not in my first try but now I'm running in my note pro 12.2 Android 10 based on Valera1978 rom, with palm rejection working good, with Netflix app working good (downloaded from apkmirror, not from play store), etc.

As a musician and music teacher I use the tablet every day for my work and it's amazing how so many years after buying it, the tablet is still updated. Thank you all!

Anyone with the same problem?

Any solution?

Could we expect any updates or it this Version more or less the last version?
[Galaxy Note Pro 12.2 Android Development] xsatquest:
There has been periods where Valera has been absent or focused on other models of tablet.

Let's hope that the reason Valera has not released any new version is because he is focused on the development of Android 11 for the P905

With that being said, even if there is never a newer version released, it has been an amazing feat for him to keep this, now 5 year old tablet alive and up to date, where samsung has clearly failed miserably.

Had it not been for people like valera, our P905 would still be on Android 5.1 and security wise it would also be very outdated.

Also, these P905 begin to show their age. Mine has begun acting up, being very very slow at times, so i suppose it is on it's last leg anyway. I have been thinking about trying to downgrade to android 9 or 8 to see if this will help, as i guess, those versions are less "heavy" to run, but i have not gotten around to it just yet.

Hey there, i followed the guide but after reboot in system i got bootloop.

[Galaxy Note Pro 12.2 Android Development] Energixia:
I always prefer latest builds of every build thinking to Security patches for example
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Will do.

I treated myself and the wife to a new Samsung galaxy tab S7+ each (I can not use mine openly until christmas, as hers is her christmas present). They had a deal with the keyboard cover.

So i will probably not be using the P905 a lot anymore, maybe i will install an earlier android version to make it more stable, and then my youngest can have it.

Not too disappointed, got just shy of 6 years of service out of the P905 which i find acceptable. Offcourse i am still a bit sad that Samsung quickly ditched support, but they have Android 11 just released for the S7+ and there are talks about atleast android 12 also, and after that i hope "Valera1978" or someone like him, will get me 13, 14, 15 and so on.

I see that TWRP is already out for the S7+ so installing a lineage OS build should be "easy"
[Galaxy Note Pro 12.2 Android Development] theAlexPS:
I flashed to August Version and only 2 issues are present:

palm rejection not working (not super important)

problems charging. I flashed stock firmware, then TWRP 3.2.2.0, then the version at the OP.

Sometimes it doent charge at all

Even with USB Charger connected sometimes it draws from the battery instead of charging and even while it charging its super slow (like 3-700mA, sometimes below that)

sometimes it even discharges overnight instead of charging (from 80 to 50 %)

I bought it used, but initally with the stock rom it wasnt that bad
[Galaxy Note Pro 12.2 Android Development] xsatquest:
Du you use a USB3 cable ?

I have found that charging it with a Micro-usb cable with only the normal size connector will result in painfully slow charge speeds.

Also, even if you use a cable with the full USB-3 sized connector, the charge speed will vary greatly, depending on what charger is used. My original cable broke many moons ago and it was the same story....Will charge, but painfully slow.

My advice is to get yourself a power meter for USB

Something like this, not saying this exact seller or model, just as long as it is USB3.0 capable it will be fine

OLED USB3.0 Charger Voltage Current Meter Tester Battery Capacity Power Detector | eBay

The range disappears automatically. Spot Welder. The secondary interface displays the cumulative capacity of the current data group. The next set of data. Capacity unit switching function. Capacity automatic storage function.

www.ebay.de

This plugs into your charger and then you put the charge cable into it and connect it to the tablet. This will give you an indication of how much current is drawn which equates to how fast it charges the tablet.

We did this on my kid's Lenovo and went through all our cables and all our charge bricks and found the exact combo that charged the fastest.

We were rather puzzled as to what exactly that the tablet decide to take more or less charge from these. Some were probably due to cheap china cables, but even beefier cables would not make it charge faster.

The worst combo's were about 200mA and the fastest combo was 1½A

There is a massive difference in charge times between the 2
[Galaxy Note Pro 12.2 Android Development] theAlexPS:
Thx for the elaborate answer, I ordered another cable (since non of the cables was orignal), I have a USB-Powermeter and most of the time it seems to draw 10w (which would be great). I will try to charge full, use till empty and recharge it a few times to recondition the battery.
[Galaxy Note Pro 12.2 Android Development] xsatquest:
10W is 2Amps

From what i can find, the Snapdragon 800 supports qualcomm quickcharge 2.0 that would support a charge speed of up to 3A or 15W, which is really slow by todays standard (Unless you have an iphone :giggle: ) but even charging at 15W would be better than 10W

I dont think i get any more than 10W out of mine, but i am also using a generic multiport charger that probably does not support QC2.0

My new Samsung galaxy tab S7+ has a 15W charger in the box, and i have bought a 45W charger for it as well, and with the 45W it charges really FAST :)
[Galaxy Note Pro 12.2 Android Development] theAlexPS:
I will have a look if it stays at 10W, the total charging time is a lot longer than estimated for 10W charging. I installed GSam Battery Monitor to record some charge and discharge behaviour.
