The heat issue could be that the battery is faulty. Other problems were sporadic, but documented fixed in the 6.5 official upgrades. Which carrier do you have, and is the phone branded from that carrier? If not, what carrier brand is the device?

thanks for the quick reply
well i'm using the phone with a vodafone egypt sim, but the box of the phone has TIM on it which is an italian carrier, i downloaded the 6.1 shipped rom for GCC & Egypt, i'm still looking for the 6.5 rom

That's too vague to really answer. All computer CPUs generate heat when in use. The TP2 gets warm under heavy use, such as web browsing, GPS navigation, games. Any reason to believe the heat is excessive? If the phone is getting too hot to hold, then its likely a battery issue as cajun suggested above.

This is normal behavior. The switch to turn off the data connection is mostly useless, it just turns it off until the next time an app turns it on again. If you want you data connection to remain off until you turn it back on, try Modaco NoData or similar mod.

Thx red for your reply,
i thought that it was heating up within spec but i wanted to check, as this is my first HTC and winmo device, hopefully i'll be able to catch up with you guys
quick question which is better simplicity rom or energy rom?

Try them both and see which one you like better. It's all a matter of opinion.

T807 Root News ?

Was just wondering if anyone with the T807 10.5 tablet might want to share any news as to gaining root for our devices. I've begun feeling like the bastard child over here. This is my first tablet and I love how well it's performing. I just really hope that the processor in this model is not worth anyones effort to try to work on.
At any rate, should anyone want to share any news or any other info on the T807 model matbe this can be the place to start ! I surly can't be alone .. can I ?? Maybe we can get some sharp developers attention.

I'm right here with you. I check Xda every day. I have pm'd chainfire already but nothing yet until the firmware is release I guess. I have tried to extract the recovery but no luck. I guess it's going to be a waiting game.

Battery is not an issue. I've only had mine two weeks. I watch a lot of videos on CNN and YouTube. When I first got the tablet my battery did seem a little sluggish. most likely the result of all the crap that was being downloaded automatically the first day or two. I noticed now that after a few cycles of charging things have settled down and I'm getting adequate battery life. to be honest this tablet is a beast and I love it. I've watched close to an hours worth of videos this morning only down 7 percent. maybe you have some rogue application running in the background ?

I didn't even have mine out of the box that it came in and I was on XDA already! I was just getting ready to install the t-800 version when I realized I had the T807 model. anyway I'm just glad I'm not alone

I got mine right when it was available from sprint and at first there was one other person on here looking but the number of people are climbing everyday. Hopefully the firmware is released soon and we will have root shortly after.

I AM NOT RESPONSIBLE IF U DAMAGE YOUR DEVICE OR DELETE DATA....PLEASE ATTEMPT THIS AT YOUR OWN RISK!
first i suggest reading through the thread linked below so u will know what i do...long story short though there is a user here by the name of @BDA_Rival who basically did the worse thing possible by trying to root his SNAPDRAGON 807 with an EXYNOS 805 cf auto root and as u may have guess ended up soft bricking it (its hard to actually permanently break it...although the fact that the odin firmware is unavailable at the moment is a bit of an issue). The ONLY reason i'm even suggesting this is because there is a known working way of getting the tab back booting & worse case u can return it & say it messed up during an over the air update or something. Ok...so what ended up saving the other guy was twrp for the NOTE PRO 12.2 905 LTE which is not only snapdragon but apparently uses the same partition structure (just to be clear...twrp only caused the device to become bootable again but does NOT actually function properly most likely due to different display drivers). So....with all of that said it is QUITE possible that the cfauto root file for the P905 could be used to root the sprint/verizon (full disclosure...the other users tab was a sprint variant) version of the tab s! Did i mention that there was a catch...well even if this does work due to the nature of how @Chainfire root method works u will be left with a copy of the stock note pro recovery instead of the origial 807 version which most likely will NOT work combined with the fact that there is a no cwm or twrp for your device yet (should be an easy fix if we could get the devs attention) and u will be left with a device that boots possibly with root as well but WITHOUT recovery.

^807 root brick thread (advise reading before trying...its only 2 pages long)
just wanted to add...the user tried the suggested autoroot in post #6 but that didnt work & the one mentioned here is linked in post #14

Id love to root, but I am perfectly fine holding off until we have our versions firmware available. Root is another thing (as I've noticed lately with phones) that I have seen, where users can obtain root with other similar models. Having TWRP from the Note Pro work is going in the right direction for us.
I'll definitely be watching the thread you linked. Thanks for your post.

I usually get 4.5 days per charge with 7 plus hours of screen time. Lots of Web surfing on network and youtube. There is a trick to condition your battery when you first use a new device it solve your issue currently.
I always setup then use my new device until the battery dies. Then recharge fully before the next use.
My setup includes tuning the sound, I disable all click tones and vibrations including touch vibration
WIFI
WiFi alway on, ALL Wifi >Advanced options disabled
SCREEN
The display I set to 25% then set to auto
Screen timeout set to 30 seconds
Smart screen disable reading disabled
Reading mode Disney
SYNC ACCOUNT
Gmail sync all disabled (when I read my Gmail I manually sync)
I have two email accounts I sync automatically for my business
GPS
GPS disbled unless in use
Disable locations and notification for all apps expect Google maps
MESSAGING
Messaging notification on but sound disabled
WIDGETS
Weather widget set to refresh hourly (this is the only widget I used which syncs)
No Facebook Twitter or other accounts , If I had them I would sync them manually
I also have a cover with magnets which disables screen when I close the cover
The procedure has become second nature for all my new devices
SG Note OG , note 2 and 3. On these phone I get 7 plus hours of talk time per day mostly on bluetooth with 2 - 3 hours of screen time over 18 hours mostly on the network, and moderate music streaming
I hope this helps

What i do is I turn wifi scanning off when connected to a network. I also set my brightness to 25 percent and keep auto brightness off which works better for me. Smart stay on, adapt display off and set to cimema mode, smart pause off, and debloated some things such as knox,flipboard,buiness+,sidesync since im rooted. Hope this helps for anyone else too!

We need to be careful about these threads-- evidently ALL US LTE versions have the SM-T**7 naming convention, including the exynos AT&T version. As far as I know, the Verizon and Sprint versions are T807.

I have the t807 for tmobile ( non snapdragon )
used the 805 auto root.
worked just fine.
I am not trying anything else, such as twrp and roms
unit the official development is done

I just bought the 807T from T-Mobile too. When you restart your Tablet holding the home, volume control and power button bring you to a download screen? I don't get that option. Instead I get a image of the android laying down with a exclamation mark coming out of his stomach and the options:
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
Am I doing something wrong?

Looks like you're pressing volume down instead of volume up.

Umm. Volume down, home key, and power button ??

[Q] Samsung Galaxy Tab S 8.4 - Screen issues

Hi there,
I was hoping you could give me some advice regarding an issue I've had for a while with my Tab S.
The screen is flickering occasionally and at times it causes the battery to drain very quickly and suddenly it reboots.
I have tried disabling hardware overlay option in the developer settings which seems to be suggested in many forums but that has not made much difference.
This has been getting gradually worse and now I am at a stage where after entering the PIN code to unlock the SIM the screen flashes a few times (white lines across the screen) and then the tab powers itself down.
I should add that I have root access and can flash roms if needed.
I believe the tablet was originally from United Arab Emirates but since I am in France I changed to a French stock rom. Before doing that the phone app kept crashing every time I missed a call...
Your help is greatly appreciated!

Well I have heard of this, but never seen it. Could you perhaps provide a video of the flickering? I guessing this is an firmware issue as people flashing lollipop said they saw this. The only thing I can think of is going back to KitKat or check if your on the latest update

Thanks for you reply.
I am actually on KitKat already, and going back to stock would mean issues with my phone app crashing when I miss a call.
Incompatible firmware seems likely but how do I know which firmware is right for my tab apart from trial and error?
Any other diagnostics? Changing CSC?

It sounds like a battery or loose connection problem to me, does the flickering happen when you move or slightly bend the tablet at all.
Have you tried the Samsung hidden codes to do an battery/hardware test.

I read a lot of people reseating the battery after having issues with battery draining, I might give this a go.
But before I open up my tab, are there any other diagnostics I can do, what are those codes for testing the phone?
Thanks

I have not tried any myself as you need a dialer and my T800 is wifi only, be careful what you are doing, there are loads of lists of secret codes.

You can use activity launcher from Adam Szakowski to lauch the hardware testing apps, just be careful what you launch, you can end with a wiped tablet.

I have now reseated the battery (disconnected and reconnected it) and so far so good!
No screen flickering and no random rebooting.
Thank you for your help!

Tab S 10.1 Touch Screen Stops Working

Ok so I am having a strange touch screen issues with both mine and my wife's tab S 10.1. It started on mine several weeks ago. When using the device, the touch screen will all of a sudden stop responding. If I press the home button, the device goes to the home screen, it just does not respond to any touch. If I press the power button to put the device to sleep and push it again to turn it back on the screen is working again but it will freeze up again, sometimes in less than a minute. When it first happened I tried to do a factory reset to see if that would help and the problem actually occurred during the initial device setup then so I know it's not related to an App that I have installed. I have sent mine to Samsung now three times trying to get them to fix it. They have replaced the screen once and said that there is nothing wrong the second time (still waiting on the determination of the third time). I have tried to research the issue but have not seen anyone experiencing the same thing. I do not have the rebooting issues that others have mentioned and turning the screen off and then back on does make it work, at least temporarily. I only remember noticing it since upgrading to Android 5 so I am going to try getting the device downgraded to Android 4.4.4 to see if that helps. Wanted to see if anyone had any other ideas. Samsung has basically told me if their techs say there isn't a problem they won't do anything for me.

A few people have mentioned touchscreen problems after upgrading to v5.0.2 mostly 8.4" but some 10.5" have you had any horizontal/vertical lines on the screen.

I have never noticed any lines. I have noticed after the first time at the repair center that the touch screen also seemed to be acting erratically, jumping around when trying to scroll or pan instead of having smooth motion. If I am able to get the device downgraded to KitKat and that improves things, I will just stay there until they figure out what is wrong with Lollipop.

I have stayed on kitkat because of the problems with lollipop, it`s just not worth it to me, but the majority of people don't seem to have any problems with it, I cannot see how upgrading to lollipop affects some touchscreens and not them all, but some people have reported the problem after upgrading i just don't know what to say.
It is normal for the touchscreen to behave erratic if you use it while your tablets is being charged, it is mentioned in the user manual.
I would say you have a faulty touchscreen, do you use a screen protector, have you tried the setting that increases the sensitivity of the touchscreen.
John.

I did not know about the charging item so that might explain the erratic behavior. I thought it might explain the screen locking up too but I know that has happened at times when I am not charging the device. I will be interested to see what happens this time when it comes back the third time from Samsung and whether downgrading my wife's device helps the issue on hers or whether we will need to fight with Samsung about hers as well.

For a couple months, I've had exactly the same problem on my Galaxy Tab S 10.5 (SM-T807V). It comes and goes in severity; some days, I lose all touch input every 5 minutes, it seems, while other days, I can go hours without trouble. Using the device without a case seems to help, as does restarting it, at least temporarily.
I have not sent my device to Samsung, nor have I performed a factory reset. But based on your experience, I'm not sure if either option is worth it.

Hi.
I would suggest removing any screen protector and cleaning the screen looking for any damage, download a touchscreen tester app from google play and testing your screen.
After searching around i found an touchscreen recalibration app for android, but i am very wary of it being fake or causing more damage or that it is for a specific brand of phone/tablet.
EDIT: I used an hex editor, and found this text within the apk file, see photo below.
John.

Well Samsung is finally sending the device back to me. This time they said the found the problem and replaced the main board and updated the software. So we will see what happens when it gets back to me tomorrow.

For anyone who is having this problem like I did. My wife has not had problems since she stopped using the device while it was charging. I have not had problems with mine since it got back related to this but whether that was Samsung fixing the issue or the fact that I also am not using it on my charger, I do not know. So if anyone else if having the problem, try the charger thing; otherwise, you may be looking at some kind of hardware issue that Samsung will have to resolve for you.

Most devices behave erratically while being charged. My HTC does it so does my tab.
Samsung even mention it.

Hi, i am having EXACTLY the same issue. The tab toucj freezes and normalizes if i lock it and unlock it with home button. I think its a software issue.

I have two of these from Verizon (T807V) and after updating them to 5.0.2 they both have this same behavior.
Quite annoying.

Any luck finding a cure ? I have noticed that the ram usage gets crazy. Any given time 1.8 gb is utilized out of he 2.77 gb available. I have uninstalled quite a few apps and shut down background processes but still the system is eating too much ram. Can any one help me on how to monitor aap ram usage ?

Hi.
I was reading the HTC forum as i have qone of their phones, and i read that some people were using an Samsung touchscreen app to boost the touchscreen as they were having problems, the app is called "SGS Touchscreen Booster" link below, The Tab S1 has it`s own touch screen booster in the settings, maybe try that first.

That's how android works. Its pointless trying to reduce ram usage if there is still ram to spare.
Android utilises ram not wastes it.

I had multiple problems with 5.0.2, ram hogging, touchscreen problems, my solution was to root and install a custom rom 4.4.4 the tablet is so much more responsive after reverting back to kitkat. I know it's not a solution for everyone but it fixed mine (SM-T800). Just throwing it out as an option.

Used kies today to upgrade to the latest firmware but still the problem continues. I have the Samsung sm t807v Verizon locked. Is there a way I can downgrade it to kit kat? Xda experts are saying it's bootloader is locked

This is a strange one I used to have the opposite. 4.4.4 every now and then touch screen stopped responding. Pressing power resolved it.
When I upgraded to LL the problem went away.
However I mostly use custom builds. At the moment the best for me is PhoeniX ROM.
Absolutely bug free so far.
Can't say I had any issues with Ironrom either.

This is a strange one I used to have the opposite. 4.4.4 every now and then touch screen stopped responding. Pressing power resolved it.
When I upgraded to LL the problem went away.
However I mostly use custom builds. At the moment the best for me is PhoeniX ROM.
Absolutely bug free so far.

I'm running BlissStalk (discontinued) but I haven't had any issues with it. I was running the CM11 unofficial also without issues. But the stock 5.0.2 it had on it when I purchased it (used) had issues. All my devices eventually end up with a custom rom eventually!

I flashed stock kitkat firmware via Odin... But it is a different tablet than yours (SM-T800). I found the following thread when I was trying to do it. Just make sure you flash the firmware for your specific model.

Bootloader unlocking
So basically searching around the internet to find a kitkat firmware for this. I think it can be downgraded but I need the stock firmware for the sm-t807v.
XDA forums have support for the other variants but for the one I have which is Verizons sm-t807v there are no STOCK firmwares anywhere.
Ashyx and steve if you know any resource, please help me out. I need to get this fixed. I don't have access to any verizon stores where I could go and get this fixed or sorted. It just me and the internet.

Stock update caused freezing and rebooting Samsung Galaxy Note 4 SM-N910P (Sprint)

I need some help guys. I received the OTA update from Sprint with my stock firmware and it totally made my phone unusable. It keeps freezing and then rebooting. I have tried everything i can think of but nothing helps.
I did i full factory reset about 3 times. 2x with the zerolemon battery i was using for the last 2 years. Then another factory reset using the stock battery that came with the phone, which didn't get used more than about 5 recharge cycles before I replaced it with the zerolemon one.
After that I thought i could undo the patch but as you guys know the QI5 firmware is not backward compatible so am i kind of screwed? I have tried rooting and loading a custom rom, the CMDMOTO is the only one I tried since it seemed to work for others using the Qi5, but i still have the same issue.
I am a bit new to the rooting world but i have been reading up to figure out my problem, any suggestions? I have TWRP, super user and titanium backup.
Thanks

Work around FOUND !
Installing the app 'Wake Lock' and using level 4 'PARTIAL_WAKE_LOCK' seems to have made everything better. I will keep this thread updated if something else happens. I guess for some reason the last patch changed something that made the cpu go inactive or sleep much more frequently or something like that.
If anyone knows how to correct this let me know. It seems that this was actually a very common problem with the other variants of the note 4 it just took a while to get to this version. I wonder if anyone else was having this issue with the N910P.
Cheers

Have you tried booting to recovery and wiping the cache partition? If it falls asleep and freezes that points to a kernel issue if I'm not mistaken. Wiping cache will NOT delete any of your data. Hold Volume Up, Home, and power til the phone turns on and you see some yellow/blue/red text in the upper left corner then release. Try wiping cache and see if it helps

When I did the factory wipe from the 3rd time onward I always wiped the cache and all other options that were available. As long as i keep the wakelock app active the phone does not freeze up and/or shut down but it is draining my battery pretty fast. I am thinking it has something to do with the phone going to deep sleep and unable to come out of it properly. I am playing around with 'Kernel Auditor ' to see if i can find a setting that will fix this issue. I am almost convinced it has something to do with the cpu clock states and Deep sleep not working correctly anymore.

I personally am a fan of 3c Toolbox for most of my diagnostic needs. Theres a free version available, check under the cpu manager tab for whatever info is relevant to you. Example..it will tell you live cpu frequencies/load, live power usage, wakelocks, all sorts of goodies
Have you tried to ODIN a factory .tar image?
sammobile dot com has the QI5 image. Just make sure tou grab the sprint one and not the unknown carrier version.

Thank you so much for posting this work around! My Wife's Note 4 has been working great for over a year, she bought it used. Then a few weeks ago a bunch of updates were pushed to it and it just started to act up.
I narrowed it down to always occurring after the phone was idle for more then an hour or so and started to look for a clue if this may be a known issue so your work around makes a lot of sense.
It does appear to be an issue with Googles 6.0.1 OS version since my BlackBerry Key 1 also received a bunch of updates but its fine.
