[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
Many of us don't have root and many of us also uninstalled may system apps, including Fire Launcher. That left us with some annoyances. One major annoyance was being kicked to the lock screen whenever we swiped away apps from the recent apps menu. Some people saw annoying flashes. Well this isn't quite a fix, but it pretty much takes care of the problem. You can now remove your lock screen completely and replace it at will and you do NOT need root access.

***WARNING: Touching any other settings on your tablet during this guide can cause a brick!!!***

1. Download and install Settings Database Editor.

2. Plug your tablet into your PC and open an ADB window. Enter the following:

adb shell pm grant by4a.setedit22 android.permission.WRITE_SECURE_SETTINGS

Step number 2 MUST be done in order for this to work.

3. Open Settings Database Editor and tap on the 'secure' tab at the top.

4. These settings are in alphabetical order. Scroll until you see:

"lockscreen_disabled" "0"

5. Change the 0 to a 1. DO NOT CHANGE ANYTHING ELSE

6. Close Settings Database Editor

Now turn off your screen. Now turn it back on. You are welcome! I have a few more tricks coming. Watch for some later!

IF THE ABOVE DOESN'T WORK, TO DISABLE LOCK SCREEN:

adb shell settings put secure lockscreen_disabled 1

ENABLE LOCK SCREEN:

adb shell settings put secure lockscreen_disabled 0

It worked almost instantly for me. Maybe wait a bit? Did you reboot? It won't work on every device. Doesn't work on my Galaxy S7.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] sensboston:
Not working for me too (Fire HD 8 2016). Also, you've made a mistake: original setting name is "lockscreen.disabled" (dot, not an underscore).
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
Disappointing. Today I got a good one though. I can't wait to get home and post a thread.

is there an updated way to do this?

[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] tobean:
Doesn't work on my Fire HD8. But while browsing through Settings Database Editor I have found something useful.

In the "Global Table" tab there's a setting called LOCKSCREEN_AD_ENABLED. Change the value from 1 to 0, save. Turn off screen, turn it on again --> ads are gone!

At least for a while...
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
Seems to be working on KFAUWI (Fire 7 7th Gen) on 5.4.0.0.

EDIT: Maybe it doesn't work with 5.4.0.1 and later?

It would be useful for those reporting success/failure to include not just device model, but fw version as well.

EDIT1: After some time playing around the system I have found out that by default it actually does not work, but if Global Table->"device_provisioned" = 0 then lock screen gets disabled, but serial number gets greyed out and developer options get disabled, while adb remains functional.

On 5.6.0.0 even change to "device_provisioned" did not disable the lock screen.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
There are settings in the "private" class that override some of these lower ones, usually in favor their using their own software. I think most device stock settings are hidden for the purpose of favoring their own software. Though with Amazon, I scratch my head. Why spend the large amount of money, to install a high tech, customizable GPS system on devices, only to spend more money carelessly blocking your Access?
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
That's fairly simple, the same goes for one of the iPhones (don't recall which gen exactly) which had two different models of radio chips, one of which did support LTE, but Apple decided to disable LTE support for that gen of the phone altogether.

Now more on the topic, checked the specs of all 7th gen tablets, indeed none of them seem to support GPS officially (for some reason I thought that HD8/HD10 might have it), but if they have the hw, it could be for testing purposes to test proprietary GPS related sw on development devices before introducing it in the next gen? Or simply they decided to drop it somewhere along the way but left the hardware (as we still have Serial/UART on some production devices nowadays, which are used only for debugging in the development stage).

On the other hand, where did you get the info that it actually has GPS related hardware? Because while exploring my device settings I only found a hint on A-GPS support (which is not proven).
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
Add a few .xml configuration files to start and there is configuration settings in the framework. Look for an app on the tablet with HERE in all caps in the title. That's the APK module making it possible. And yes I figured out a way to modify framework settings
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
I see, just checked MT8127 specs, and indeed there seems to be integrated support for GPS with GLONASS, that may be something interesting to play with.

EDIT: HD8/HD10 even have broader support of GPS related technologies according to their SoC specs.

Yeah, I was following root progress thread, even tried Blueborne exploit (the one published by Armis labs on github) on KFAUWI without much success as there is no access to /proc/<pid>/maps. And framework-res.apk mod looks promising only for devices having root, as getting required permissions outside /system is rather problematic.

Yet I was surprised that WRITE_SECURE_SETTINGS can be assigned outside /system. :D As I was poking around com.amazon.dcp.permission.DISPLAY_DEBUG_UI for quite some time.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] lakitu47:
Do you have any idea if you can grant something like Activity Launcher the DISPLAY_DEBUG_UI permission? Some of the activities gave me errors when I tried to open them, saying they require com.amazon.dcp.permission.DISPLAY_DEBUG_UI.

The thing is, this appears to be a custom permission added by Amazon, not available in the official Android documentation.

Would Activity Launcher even be capable of launching certain "hidden" activities with this permission granted? Presumably you would grant permission over ADB the same way as WRITE_SECURE_SETTINGS?

Any ideas would be great.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
Tried granting it to other apps and it resulted in "com.amazon.dcp.permission.DISPLAY_DEBUG_UI is not a changeable type" the command I used was pm grant com.amazon.dcp com.amazon.dcp.permission.DISPLAY_DEBUG_UI so yes, the syntax is the same with custom amazon permissions. Also execution of dumpsys package com.amazon.dcp shows that app already has DISPLAY_DEBUG_UI permission.

My guess is that it requires root, as even when I am launching activity from adb shell (not in context of activity manager) I get the same error that it requires the permission, and the same goes for some other hidden amazon applications.

EDIT: you can get list of device permissions by executing "pm list permissions" without quotes from adb shell, there are at least a few interesting ones.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
That's a great question and one that hasn't been asked before. I can tell you I've been able to, in some apps, modify the manifest permissions. For example, I can use an app to edit the manifest of Jack Pals terminal emulator to add the secure settings permission and have it successfully install etc. I never thought of doing the same with activity launcher and if successful, seeing what happens. This could be very interesting. If you give me a few copies of some of the manifests permissions, I can see if a recompile and install will hold.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] lakitu47:
I attached a text document with ALL of the permissions listed by "pm list permissions" since it was too long to put here.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
Give me a few hours to see if I can modify the app. If I can, I'll upload a. APK
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
Questionable whether anything would change, as I don't see where activity launcher would need write secure settings permission.

On the other hand I did some digging on the "not a changeable permission type" message, and this provides some answer on what it might be expecting in order to activate?/assign the permission.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] lakitu47:
Interesting. So each permission has a certain "protection" level?
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] gabosius:
If I understand it properly protection level is associated with the application itself rather than the permission, but some permissions can only be granted under specific circumstances.

For instance, some permissions can be granted only for apps in /system/app or /system/priv-app folders while others according to the link I posted only to apps which have specific protection level set in the manifest of the apk file. And in this case understanding the real reason behind "permission is not a changeable type" needs some analysis of the source code of the OS, but is likely to be a dead end, in particular if the protection level is set to signature.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
I can modify Activity Launchers manifest just fine. But even with root, i installed it into system/app and it wasn't performing any better than before. Good to know it accepted the Amazon permission though. But wasn't granted it.

Sadly disabling the lock screen this way didn't work for me. HD 10 (7th Gen) 5.6.0.1, rooted.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
For some reason it doesn't seem to work on the HD 10. I recall seeing the settings in the framework if I'm not mistaken. I'll have a look into it later today.

Update

Just an update about this thread's laudable goal:

On Fire 7 (7th) 5.4.0.0 and Fire HD 8 (7th) 5.6.1.2, although the setting of lockscreen.disabled does nothing, setting Global Table->"device_provisioned" = 0 (a reboot may be needed) removes the lock screen entirely. Unfortunately it also leaves the quick access menu (swipe from top) devoid of apps, controls and notifications. As mentioned previously it also grays out the serial number and blocks access to Developer Options. There may be other unwanted side effects.

Still it could be a price worth paying for those who really want to get rid of the lock screen.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] dondraper23:
Awesome! Thanks!
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
The lockscreen.disabled may have been patched. It worked on 5.4.0.0 and that was quite a bit ago.

Me and a buddy have been working with a kindle fire for a while now and I have seen this question posted before so as of May 2019 the following command is confirmed to work, tested on two devices.

adb shell settings put global device_provisioned 0

Set it to 1 to undo it.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
Still not permanent and with the current policies in place, and inability to remove parental controls, will eventually be overwritten and will default.
[Fire HD 8 and HD 10 Q&A, Help & Troubleshooting] DragonFire1024:
it took me several hours but I have convinced fire OS that Google services is now the device owner and I have been able to uninstall and completely disable all parental controls and functions along with it and still keep open all lockscreen options. I may post the guide I may not because this was a real pain. but as long as the file holds and the system continues to think that Google services is the new device owner then all parental restrictions are now gone and will stay gone.

[Galaxy S 4 Q&A, Help & Troubleshooting] Shaamaan:
Hi,

I'm having some trouble restoring the official FW on my old S4. The idea was that I wanted to give it to another family member, and would prefer to give them the stock FW rather than deal with whatever potential issues a custom FW offers (don't get me wrong, custom FW tend to be awesome, but I hope you get the picture).

I downloaded the latest, official FW for this phone and proceeded to try and flash it using Odin (MD5 file specified as PDA). Alas, this got stuck on flashing BOOT. So I tried to hook up the USB cable to a different USB port (I was using a hub before) and that went through BOOT, but failed with a write error later d.wn the line. This, alas, has been my experience thus far. I've tried other Odin versions and another FW version, all failing with the write error.

I've even tried to use KIES to restore, but now KIES fails to recognize the phone at all (neither normally, nor in the recovery mode as the phone suggests, nor can I "initialize" the phone, as apparently the GT-I9505 does not support it).

I do feel not all is lost, as I can get into the download mode without issues, but I'm unsure how to proceed. Please help.
[Galaxy S 4 Q&A, Help & Troubleshooting] Shaamaan:
OK, I think I got it.

It turns out my USB cable was sh*t. With a new USB cable it works fine.

Do You know how much money is it worth:

Samsung Galaxy S6 Edge Plus 32 GB Black SM-928F, perfect condition. No Scratches. The Best Protection hrdglass and gumm in the world. Never tripped KNOX. Never rooted, modded etc.

Can You help me?

Thank You for your Time.
[Galaxy S6 Edge+ Accessories] androidbadboy:
In my estimation around 280 $ -/+ 20 $ on eBay.
[Galaxy S6 Edge+ Accessories] Rehvix:
I would say a little lower now, maybe +/- $220
[Galaxy S6 Edge+ Accessories] androidbadboy:
How do You all XDA users would judge the worth of my phone after the premiere of S9/S9+
[Galaxy S6 Edge+ Accessories] Rehvix:
My variant (G928T) maxes out at about 200 USD. If you have an F variant, I would say your still at about 220 USD, assuming perfect condition.
[Galaxy S6 Edge+ Accessories] Segamalaga:
I have sold mine (G928F 64GB) for 220€
[Galaxy S6 Edge+ Accessories] androidbadboy:
I don't wanna hurt Your feelings but that is way too low price for the rare 64 GB version assuming it's in perfect condition like my predecessor said.

In EU you should be able to get as much as 300 USD minimum.
[Galaxy S6 Edge+ Accessories] Segamalaga:
It was in perfect condition (Knox 0x0) and I think this is a good business cause in Spain there are a lot of second-hand market. I've sold above it's price
[Galaxy S6 Edge+ Accessories] androidbadboy:
Oh I forgot that that 220 was in euros not dollars lol :)

BTW Remind me, (Knox 0x0) = Tripped Knox?
[Galaxy S6 Edge+ Accessories] Segamalaga:
No man, tripped knox it's 0x1
[Galaxy S6 Edge+ Accessories] androidbadboy:
So in Your opinion You've got a very good price on Your S6E+?
[Galaxy S6 Edge+ Accessories] Segamalaga:
Yes, absolutely. But, as I said before, here in Spain de have a huge second hand market.
[Galaxy S6 Edge+ Accessories] androidbadboy:
So it's a huge competition for and kind of used phone?
[Galaxy S6 Edge+ Accessories] Segamalaga:
Not exactly. I mean that there are a lot of good phones on selling and this makes prices to decrease
[Galaxy S6 Edge+ Accessories] androidbadboy:
Yep, that sounds correct: the invisible hand of the market is at work ;)

I know that pain, when I wanna sell something and find out because of a lot of competition a successful and quick sell is only possible when I lower the price very much :(
[Galaxy S6 Edge+ Accessories] Segamalaga:
Yes, that is mate
[Galaxy S6 Edge+ Accessories] androidbadboy:
BTW It turned out that the sixth edition of Samsung Galaxy was the last one with tough to scratch screen (Gorilla Glass on steroids?). Starting from S7 trough S8 and now S9 it turns out that it is ridiciously easy to scratch the surface of the screen. Be aware XDA Friends! As if it were not enough Samsung made it difficult to find a good protection.

For example - Samsung officials do not recommend using a hard glass cover on the front of S8 because in their opinion it will block some features of the phone like face recognition etc. It's kinda strange because these 3rd party hard glasses have special wholes or not dimmed areas to let the device scan user's face and measure the distance from the head.

The next problem they "create" is that the back clear cover sillicon compared with hard glass will not completely "close" S8's potential exposed to scratch areas. In my opinion it's just another way to quickly make a Galaxy generation damaged so people more likely buy a new edition of Galaxy S. The battery problem is another argument :( After 3 years the battery drain of a Galaxy is making a user furious.

Hi there all, I have searched and read and then searched some more, even on other forums but (probably due to my technological stupidity) I have not found an answer... I need to use Chinese sometimes when emailing or smsing etc and I like to use the hard keyboard if its going to be a long one (amazing how quickly I got to like the qwerty keyboard)... now I have AEKmap so I can quickly change from the English one to a Chinese one (or so I thought) but I find that it does not have a Chinese keyboard listed in the options (just the default and a couple of Russian options). I have CEStar installed and also the d-ear Chinese sip as well as the 10 Key d-ear sip... but still cant find an option to enable the Chinese mapping for the hard keyboard. Am I missing something obvious (all to likely given my skill with tech stuff) or do I need to find a Chinese keyboard map? thanks for any help anyone can offer...

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] ruffruff:
install CESTAR or A4 pinyin input for Kaiser

then, open up your registry editor

go to HKLM->HARDWARE->DEVICEMAP->KEYBD

change curlang to 0x804

restart your kaiser

slide out your keyboard, the Sym/Tab button should allow u to switch to chinese input (if yours is a Eur/US device)

if yours is a Chinese APAC device, then you should see a chinese character at that button.

the button is on the left of the space bar
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] zcsx1985:
I have CEStar and it works perfectly for me. as long as you select the chinese mode, you will be able to eithe type in chinese with the keyboard (slide-out) or type with the stylus (regular)
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Shadowdh:
Ruffruff... thanks for the advice, if I make this regedit will it be chinese layout all the time or can I select between default and Chinese in AEKmap?

Zcsx1985 yeah I sort of worked it out, I had to select the sip in portrait and then when I slid the keyboard out it worked fine...

Actually now that I have done that I can bring up the sip switch thing (little triangle next to the keyboard symbol on the screen) after sliding out the keyboard which I couldnt do before and now its all ok... well so far... cheers

Hi Shadow, how did you get the d-ear sips to work? Any special configurations necessary?

I have not managed to get them to work properly. when i type any messages, it appears right on my kaiser screen but when sent, my client will receive a whole page of question marks.

Did you overcome that issue?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Shadowdh:
I didnt do anything special, just install and then use... is your clients phone set up to receive Chinese characters cos thats the only reason for them not being able to receive them I can think of.. of course I am not too knowledgeable about such matters so it might be something else... if it is perhaps try uninstalling and then reinstalling... plus I am using a cooked ROM not stock...

I'm using a WWE ROM and after I installed CE Star and the input method, it works great without any registry modifications

but one thing that bothers me is everytime I need to open the soft keyboard, press the "Chinese" symbol" once, then I can use the "input switch" button on the hardware keyboard to switch between typing English and Chinese ...

Tony as Kw31 says, CEStar is my main IME and it works fine, only conflicts with MS reader when its in Chinese mode (and also Pleco2 but thats another program)...
[Samsung Galaxy Note 8 Questions and Answers] Nebell:
I've noticed lastely that my pen sensitivity is different in the middle of the screen compared to the corners. I have to press down the pen harder to actually write something, while on the corners I can write normally.,

This was not always the case, the problem appeared just recently. The pen has bad sensitivity in the middle regardless if I try to write or just scroll on a webpage with it.

Restarting the phone didn't help.

I have a custom rom which I have not upgraded for months now (I'm waiting on Oreo roms).

The digitizer seems to work fine when I use my fingers.

I have uploaded a screenshot testing the pen. The corners are where I gently just swiped with the pen. As you can see there's nothing in the middle.

Could this be software (rom) issue, digitizer losing response or the pen itself? Any ideas?
[Samsung Galaxy Note 8 Questions and Answers] Gizmoe:
None of the above. The pen has its own sensor behind the screen. It got damaged somehow. Time for a warranty replacement.
[Samsung Galaxy Note 8 Questions and Answers] WaxysDargle:
do you have a case on the phone? any magnetic closure will cause exactly this
[Samsung Galaxy Note 8 Questions and Answers] Nebell:
Correct, I suspected it and removed the case and it solved the problem.

I recently bought https://www.aliexpress.com/item/Zim...lloy-Metal-Cover-for-Samsung/32828780058.html

It's a fantastic case in every way, except that it makes Spen go crazy.

Will it cause any permanent damage or am I safe to continue using it?

It was the magnet messing around, the problem disappeared when I removed the case. Good thing I don't need to RMA this, I have 2-step verification for everything haha.
[Samsung Galaxy Note 8 Questions and Answers] Gizmoe:
Glad it was easy!:good: I'm surprised a case would be made that interferes with the pen coils. That's annoying. Good thing it didn't permanently damage it. Having to RMA would have been lame. What case did you buy, I'm just curious.
