I have no idea why people want nav bar on zuk z2? We got the hardware button which provide all feature as nav bar since 2 year ago.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] vinay069:
Nav bar plays a major role in Android q roms .... But most of the people don't actually know it's relevance.....

Lack of nav bar is making a conflict in switching of multiple apps switching gestures and killing the actual fluidness of gestures.. Hope devs will realize it over time
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] locolyric:
I just flash the latest version. I thought they are talking about the old nav bar . And i found out is the new nav bar are missing. However, if pe team make an option to let user choose to on and off for that is much better. I can live without it, because my phone never have that bar until android 10.

I do hope the hardware button can back to swipe left and right to previous app.

Wut ? Swipe from left on edge gone with the nav bar ? Ok. I want it back.

After the Android 10 beta update of 28th Sep, the NAV bar is gone though 3 button navigation is enabled under gestures/system navigation. It was visible and working in the 21st Sep beta (previous beta). Any one faces a similar issue? what is the way out?

For a Beta Rom, it' quite good.

Jio Volte works.

Only issue I faced is Gcam. HDR process bar stuck. But image saved. Portrait mode 2nd image is showing i gallery after a minute or so.

Charging seems fast enough.

Hope, stable rom won't have a problem with Gcam.

[LG G5 Questions & Answers] ezzony:
I use a uGreen multi functional adapter for attaching usb memory sticks and HDMI cable for TV use with my G5. It works great apart from the picture breaks up on the TV from time to time mostly when playing video and curiously only when I have a sim inserted and active.

I'm wondering if the adaptor is somehow incompatible with my G5. I have 2 G5's and both have the same problem. When I use the adaptor with my V20 it works perfectly. Or maybe it's a kernel issue which might make it resolvable.

Has anyone had a similar issue and does anyone use any other brand of adaptor that doesn't have this issue?

edit: this is the one I use https://cf1.s3.souqcdn.com/item/2018/05/02/32/73/00/34/item_XL_32730034_131939745.jpg
[Shield Tablet Q&A, Help & Troubleshooting] SupremeScotian:
I bought a fairly new 2015 tablet a guy a bought it from had Blisspop OS on it v3.8 -( it was mint in box ) anyway in trying to get it to accept the official Nvidia OS - it failed many times in Twrp recovery i hit the wipe by mistake now the hard drive got wiped and it only hangs at the Nvidia Logo - is there anyway top recovery it? I had a backup on my sd card of the Blisspop OS but i was hoping i could access it via ADB fast boot ( been reading yet unfamiliar with the process ) when i hold the pwr button and volume down it takes me to the recovery but it just goes back to the logo screen it not even going into twrp ( no dounbt because the drive is wiped ) its this futile or can i recovery it somehow
[Shield Tablet Q&A, Help & Troubleshooting] fpozar:
If you can enter TWRP you are saved

As long as you can enter fastboot mode you are safe as well :)

In case you don't have twrp you need to enter fastboot:

I believe its power + vol down (might be up its beeb years since Ive entered anything with button combinations). When you're there follow this guide to flash TWRP. You will also most likely need to flash some old version because new ones require the newest firmwarw and bliss os is quite old (again I might be wrong). When you have TWRP follow Lineageos [OFFICIAL] by steel thread to get the latest firmware file and flash it. Then you need a rom and that can be any one you like (you aon't find a rom on Steel's thread but there are new LineageOS threads).

Good luck ;)

[Samsung Galaxy Tab S6 Guides, News, & Discussion] JarkMackson:
A little vent session: I’ve had note phones since the note 2 and I love them. I can’t stand iPhones but when it comes to making tablets, Apple is leaps and bounds ahead. Samsung has never been able to get it right...

Tab S3- Laggiest least usable piece of hardware I’ve ever owned.

Tab S4- Keyboard is almost unusable because the keys double & triple type all of the time.

Tab S5- didn’t bother, neither did Samsung.

Tab s6 - Keyboard deactivates when you swing it around to the back but it won’t properly activate the on-screen keyboard., now the WiFi cuts out every 10 minutes and requires a reboot to be able to get it to work. Seriously, Samsung should stop making attempts, they find a new way to mess it up every time.
[Samsung Galaxy Tab S6 Guides, News, & Discussion] gottahavit:
how's that trackpad mouse support on your ipad? oh wait.. no mouse support!

How big of an SDcard can you add to the ipad? oh wait no SDCard support!

How is playing your games from your Note Phone on you Ipad? Oh wait Apple has banned account sharing with android.

Typing this up on the keyboad with mouse support. Is it perfect? Hell No, is it better than letting Apple decide what is possible and what is not? F Yes.

I can deal with tearing off the keyboaed rather than wrappig it around to the back until they fix the firmware. You kep waiting for mouse support in IOS.

Interesting I find most people frustrated with samsung(or android) are frustrated because they couldn't open the box and have everything the wanted without having the change any settings or install any apps. Apple appeals to the masses who just want it to work(as defined by apple). Don't get me wrong that's a valuable thing and a valid reason for a lot of people. Also Apple makes a hell of a piece of hardware, but that OS is just so vanilla brown bag I just can't use it.
[Samsung Galaxy Tab S6 Guides, News, & Discussion] JarkMackson:
I'm no stranger to customizing Android devices, I've rooted most of my phones over the years and I also know which apps to install. I'll agree with you about iOS, I'm not a huge fan of how much control Apple needs to have but at the very least I can connect to Wi-Fi. That's something I can't say about my Samsung tablet. Also all of the Apple branded accessories have worked right out of the box. I can't say that about Samsung either.
[Samsung Galaxy Tab S6 Guides, News, & Discussion] gottahavit:
no issues here with wifi, though I did exhange one tab for another to resolve poor battery life. Ive use both at home and on my work wifi without a problem. Here's one I just found, if you are in dex mode and have keyboard attached, then the on screen keyboard button works as epected.

[Samsung Galaxy Tab S6 Guides, News, & Discussion] nrage23:
I had no major issues with the S3 the Samsung software at the time was not very smooth. The S4 keyboard worked well with mine. I never saw any kind of multiple keystrokes. No idea about Wifi on Tab S6 because it never cut off on mine. Maybe you should have swapped yours out for a hardware defect. The S6 is far and away the best android tablet available. As for the keyboard folding around back there a couple threads with ways to fix this. If you cannot search or contact Samsung when you have an issue, maybe you should just stick with Apple and stop making threads like this.
[Samsung Galaxy Tab S6 Guides, News, & Discussion] JarkMackson:
So, if you experience no issues with the S4 keyboard you are in the minority and if you've never had an issue with another Samsung tablet then you must have the Magic Touch. Check the threads. You're right, this is the best Android tablet available right now and I want to love the damn thing but I feel like Samsung screws something up every time. I have contacted Samsung support and I do know how to search. The issue with the keyboard has only a somewhat serviceable work around and only if you use the Samsung keyboard. I like gboard. . Also, I started this thread stating that I was going on a bit of a rant, if you cannot handle someone criticizing a product that has real issues maybe you should just stick with not looking at the threads or just not responding. ;)
[Samsung Galaxy Tab S6 Guides, News, & Discussion] Mr. Orange 645:
Tab S4 was my first Samsung tablet and I LOVED it. I had the same infuriating issue with the keyboard, but a couple months ago, Samsung pushed an update that fixed it. I only sold my S4 so I could buy an S6. Now I'm just waiting for it to ship. Backordered until October 4th, unfortunately.

Sorry you've had a rough go of it. Technology is a fickle beast. Sounds like your WiFi issues may be an issue with your router, or you got a faulty Tab S6. Should be covered by warranty. The keyboard thing does sound annoying, and I've contemplated how I'll work around it when mine arrives. For now, I'll probable detach the keyboard when not using it. But I believe Samsung support said they are already working on a software fix for it.

But iPad may just suit your needs better. I just can't stand the iOS ecosystem. I have to use an iPhone for work, and I'm sure in the next year or two they will force an iPad on me. I prefer Android, and the Galaxy Tab S4 was a brilliant piece of tech. Loved every minute of using it and miss having it with me now.
[Samsung Galaxy Tab S6 Guides, News, & Discussion] Reuben_skelz92:
And on another note the iPad keyboards have always been worse with mushy keys
[Samsung Galaxy Tab S6 Guides, News, & Discussion] JarkMackson:
I didn't realize that Samsung had pushed a fix for the keyboard however that's still really stinks because they did it just in time for them to release a new tablet. I honestly hate the iOS ecosystem too.. it's far too Limited in far too bland for what I'm looking for, that's why I bought every single Samsung tablet since the note 10.1. The most frustrating part I find about them is that they are so close to being good and it's stupid little things that should have been taken care of pre-production or at the very least as soon as they popped up that keep me having to go back to the iPad. Maybe when the LTE version of this tablet is released they will have resolved the issues.

What does "swing it around to the back mean?" If you mean folding it under so it's sitting keys down on a table wouldn't it be easier to take it off and just use the kickstand? I'm curious what use cases require swinging the keyboard around back and why an Apple tablet does that better.

I agree. I don't like Ios at all. But I have an ipad for years from my job. I use it only there. For my personal use I got the tab s2/4/6 , the sony ones, huawei, xiaomi...... And when you know all the « good» tab, it's obvious that IPAD is so far better.

And it's not really about « apple is the best» , but more about « other brands doesn't care anymore about tabs» ....

Ios 13 is pretty good about tab, when android still not adapted at all for big screens.

Samsung keyboards are Junk! The S6 as a Tablet is Excellent. Ditch the Samsung Keyboard and get the Logitech Illuminated K810 Keyboard and an MX Anywhere S2 mouse. They are perfect for tablets using Bluetooth. Love mine! The keyboard is just a bit wider than the tablet and mouse is small. It's really a joy to use with the Tab S4 and now the S6.

[Sony Xperia XA2 Questions & Answers] st33rp1k3:
TL;DR: After rebooting to slot b with TWRP following a failed LineageOS flash, my XA2's screen is broken: showing only flashing vertical lines. This problem persists after an attempted reversion to stock firmware and software using Emma.

Apologies for the long post, but I'm at a total loss even after a lot of reading, and would appreciate any suggestions to turn this £180 paperweight back into a phone. I'm not trying to blame the LineageOS or TWRP teams here; any error is my own :)

What I've done to install TWRP on my XA2:

Installed the newest system updates (including an update to Android 9)

Unlocked the bootloader

Enabled developer options and USB debugging

Installed TWRP as per the instructions on TWRP's XA2 page (i.e.: not flashing TWRP using fastboot)

Happily rebooted into fully-functional TWRP

I then tried to flash LineageOS using TWRP:

Formatted data

Wiped system, cache, and internal storage partitions

Attempted to flash LineageOS (lineage-16.0-20190916-nightly-pioneer-signed.zip)

Flash failed with "ERROR: 1"; "Error applying Update: 18 (ErrorCode:: kdownloadPayloadPubKeyVerificationError)"

After some reading I found a post which suggested rebooting into slot b to fix this problem

Used TWRP to reboot into slot b

Screen is now glitching: flashing vertical lines on a black background; Sony splashscreen doesn't show during boot, nor does the unlocked bootloader screen

Here's what I've tried to fix it:

Flashed stock firmware, and then software, using Emma (which showed both operations as being successful)

Attempted to reboot to slot a using fastboot

The current state of the device:

Broken screen showing only flashing lines and colours (no splashscreens)

Boots to voice-assisted setup (!?) despite the broken screen. From what voice assist is saying, there seems to be a system there (e.g.: I can take screenshots)

Can be powered on and off, and put into flash mode (green LED)

Is still recognised by (and can be controlled using) fastboot

Thanks for reading. Any help is much appreciated :)
[Sony Xperia XA2 Questions & Answers] st33rp1k3:
Update: I've tried using Newflash to flash stock firmware downloaded via Xperifirm.

The operation complete successfully, and the device boots (thankfully not to voice-assisted setup), but the screen is still broken, as described in my OP.

Does anyone have any suggestions?
[Sony Xperia XA2 Questions & Answers] st33rp1k3:
Alright, on the off-chance that anyone comes here with the same problem (i.e.: XA2, broken screen), I seem to have fixed it by:

Powering off the device

Putting it into flash mode (green LED)

Fastbooting a special TWRP .img with "fastboot boot /path/to/twrp.img"

Rebooting the device normally

I have no idea whether my previous step of using Newflash is a dependency of this working, or whether it works on its own

Now my screen works again, but every attempt to flash LineageOS zips with TWRP fails as described in my OP:

Error applying update: 18 (ErrorCode: : kDownloadPayloadPubKeyVerificationError )

Updater process ended with ERROR: 1

Error installing zip file

This happens:

With several different nightly pioneer builds

With several different versions of TWRP

Trying to flash the .zip from SD card

Trying to adb push the .zip

Trying to flash from the fastboot booted .img

Trying to flash from different versions of the TWRP .zip, flashed from the fastboot booted .img

Despite having already flashed the older firmware version (50.1.A.13)

So I am again at a loss :eek:

-Formatting data and wiping system partitions
