I don't even have a second SIM unless I pry one from my wife's phone, but she's unlikely to let me do that. Still, from what I read on other forums, people got no issues with dual SIMs.

Certainly would take the time to find the 4/64. It's a snappy web browser/book reader.

Xiaomi Mi 6 with LTE enabled clocked out at 18ms/52.26mbps/10.17mbps. Not that huge of a bump as I was expecting, really. Still, 50mbps on the go is nothing to sneeze at. Neither is 27mbps, to be perfectly frank.

I remember them WAP sites on GPRS. Now that was a hellish invention.

Speaking of purchasing them 4/64's, they're in abundance on AliExpress, if you're into that kind of thing. Not sure where you are but we get free shipping and some kind of warranty.

Never personally bought anything from AliExpress; that is not an endorsment. On the other hand, if you do buy one, get one of them proper Lenovo-made cases, they're top-notch.

I would like to thank you again for your advice.

I found one in Germany and one in UK. It has customs outside EU.

I would like to ask you what languages the tablet supports? Can you upload a screen capture ?

Thanks again.
[Thinkpad Tablet General] wonderfulme:
Can't provide a screenshot since the wife is currently sleeping with it, but it's pretty much stock Android 7 with everything from Hungarian to Malay to everything you've come to expect. Really the last thing you ought to be concerned about.

It's not a Chinese version with google translate version of English by any means.

Here are some tips for our devices.

To be able to write to system partition (device freezing when using Adaway, and some otherapps) you have to remount system partition as RW.

I have made a magisk module for this task. If you have magisk installed just flash the attached zip in twrp. No more freezes with rooted apps.

If you are using an sd card you might have noticed, that log files are being created constantly in sdcard/logs folder. After few days it can grow up to couple of gigs. To disable that you have edit your build.prop

change

persist.service.sdlog.enable=1

to

persist.service.sdlog.enable=0

Save and reboot.

Get rid of bluetooth logs btsnoop_hci.log being written to your internal drive:

go to

/system/etc/bluetooth/bt_stack.conf

change

BTSnoopConfigFromFile=false

to

BTSnoopConfigFromFile=true

Here's how I installed lineage 16 after many soft bricks!

Hi guys

This is my 1st post here only because I've had a nightmare getting lineage to install on my Lenovo TB-8704F tab 4 8 plus. I think I have tried every guide I could find and nothing worked. I always ended up either stuck on the Lenovo boot screen at the very start or the lineage boot screen.

What finally worked was a dirty flash on a clean stock 8.1 system.

Basically all the guides are fine to get you to twrp. But they all fall down after that. So if anyone else is struggling;

Once you have got to the point of fastboot boot twrp.img try this.

Fastboot flash recovery twrp.img

(This permanently installs twrp to recovery)

Then boot into recovery

Then format everything in twrp

Then wipe the top 3 tick boxes in advanced wipe in twrp

Then find the page on needrom that explains how to fix a soft brick for the tab 4 8 plus and download the Android 8.1 image. You will have to create an account which I was wary of doing but this was the last straw for me.

You need to extract it to an SD card. The zip should only contain boot.img recovery.img and system.img

If it doesn't, you downloaded the wrong one so try again.

Once this is done put the SD in the tablet and press vol- & power to go to fastboot and connect to your laptop.

From here I followed the instructions to flash boot and recovery and then dd system. But I had to dd system twice for it to work for some reason.

Once done, reboot the tablet and wait while it boots into stock 8.1. When it gets to pick the language turn it off and put it back into fastboot mode.

Then flash twrp permanently with fastboot flash recovery twrp.img

Now put your SD card with lineage.zip (whichever version you choose) into the tablet and boot into recovery.

Now just install lineage through twrp. DONT WIPE OR FORMAT ANYTHING!

Once it completes reboot and lineage should boot with no problems. Once it gets to the language choice power off and boot into recovery.

Now do a factory reset.

Then you can install other stuff like magisk or gapps or whatever.

Once complete, reboot and enjoy!

Hope this helps someone else who is pulling their hair out like I was.

So you know, lineage 16 solved my WiFi issue where it would drop altogether randomly and consistently as well as the random screen blackout while watching full screen video. Both issues came after upgrading to 8.1.

I already own a Tab 4 8 Plus with 4/64 GB running LOS 16 (Android Pie 9. I have been happy with this device. My trusty N7 2013 has died. The battery appears to be charged. Holding Power button + Volume down does nothing. I have tried reseating all the cables and connectors.

I am looking for a new 7 or 8" tablet that is developer friendly. To me this means that the tablet can be rooted. TWRP would be nice, but I am living without that on my Pixel 3 XL running Android 10. I discussion group on XDA would be even nicer. The tablet also needs to have a USB-C port and support Nova launcher.

I may get another Tab 4 8 Plus. Is there anything out there that is better?
[Thinkpad Tablet General] Ja_som:
Hmmm, I don't think there is a device which will not support Nova or any other custom launcher...

But, to the point. I'm also thinking what will be my next device. I think I will change both of my devices for one, a bit bigger phone, like 6", probably OnePlus. Because there is no tablet which is interesting for me.
[Thinkpad Tablet General] dahawthorne:
I was waiting for other suggestions but I don't see many...

I did some research just a few months ago when I wanted to replace my Nexus 10 - QHD display & stereo speakers make it a hard device to replace. As you know, @swieder711, I too have a TB-8704F and it's a nice little machine for the same reasons, if a bit small with tinny sound in comparison to the N10.

I found nothing I wanted. Huawei is out for me because they refuse to allow unlocked bootloader, Lenovo are out because they appear to have little or no interest in keeping their devices updated, and there are few others who produce tablets any more.

Samsung is of course the big one. Their S series is too expensive for my liking, and the A series, though reasonably-priced and rootable, has "stereo" speakers on one side of the device, which makes it useless for media watching.

So I'm sticking with my N10, despite it being old and creaky. It plays media superbly, and I don't think that the current (and possibly the future) tablet market will produce anything better.
[Thinkpad Tablet General] swieder711:

Hi everyone.

I am looking for a stock ROM in flashable zip, or a twrp backup (no data partition) for the TB8704X.

Does anyone know where I can find it?

Today, out of nowhere my tablets power button / fingerprint scanner came out. I dont recall myself handling it badly. Never dropped it. The rest of the device is in prestine form. So I was guessing if those parts are simply glued? Are the really broken and do I have to buy new ones? And does new parts available anywhere online? (I didn't find any information / disassembly / assembly instructions / videos online)

Thanks all for the help and advice. Got my Tab 4 rooted with no problems!

Does anyone know how to remove the persistant Alexa Assistant icon from the bottom right of the navigation bar, though? I froze the Voice Assistant app via Titanium but it still comes back after a while. It doesn't do anything with Voice Assistant frozen but is still just there. I'd also like to be able to remove the 'clear all' brush icon from the Recents but the Alexa one is way more annoying. Thanks for any help.

edit- Just saw that Lenovo have officially marked the Tab 4 as part of the Amazon Alexa range. Sigh. I fear this might be really difficult to remove. Again, any help would genuinely be appreciated.
[Thinkpad Tablet General] cmvrgr:
Nice tablet perfect as a dual sim gigantic phablet replacement :)

I will wait to see if Huawei mediapad had dual sim, led flash, ear piece for phone calls like the features of Lenovo tab 4 plus and then I will have to decide.

I would go with Lenovo but in my country only the 3gb/16gb is available and I want the 4gb/64g version that I will have to get it from another country. That make problem with the guarantee.
[Thinkpad Tablet General] zelect0r:
I have rooted the tab and remove all of the bloatware incl. the alexa app.

No alexa icon in the nav bar :)
[Thinkpad Tablet General] skttrbrain:
True, and that does work for about 95% of the time. But (for me at least) if you install another unrelated app, it reappears for a while.
[Thinkpad Tablet General] zelect0r:
Not for me dude, sry, my tab is now rooted for around 24h. I have removed all bloatapps with sdmaid and titanium backup.

After the removing comes a lot of apps from playstore to my system.

And some reboots later the Alexa icon is no more showing since yesterday.

How too? Its deinstalled.
[Thinkpad Tablet General] skttrbrain:
Tried freezing it, not really a fan of deleting stuff in system but also deleted any referenced directories and still nothing doing, it comes back whenever I install a new app via apk. It's bizarre. I guess I'll have to just mess around with it a bit more, or with any luck we can get LineageOS to remove the crap for all of us (not likely though looking at how many Lenovo devices they support).

Google Play Services

Hi,

I bought the Tab4 10 Plus (X704N) from China not knowing there would be issues with Google Play Services.

Am trying to install Google Play but no luck so far. Have not attempted to root the device as yet with the fear of bricking it.

Could anyone please help and guide? Am unable to use this Tab productively without Google Play.

Cheers,

Sumeet

[Thinkpad Tablet General] Ja_som:
I bought TB-8704F (4/64GB WiFi) few days back as Nexus 7 2013 replacement and it is really good tablet, nice looking and fast.

Does it have only blue notification light? I saw also red, but only with battery info (charging, charged or low, I'm not sure when it was :) ). Before I used LightFlow to set notification light and sound for apps, but on this tablet the light starts flashing right after I install LightFlow even if I don't have any notification :( , so I installed Light Manager, but I think it is pointless when the led is only blue (no matter what color I set), and I can't set a sound there.

Also, I had to factory reset my tablet yesterday when I had almost everything set, after setting "Custom Navigation Bar" app I got System UI stopped working error and I could not do anything, only factory reset via TWRP helped. Sad, I wanted to move navigation buttons.

After I read posts about rooting I'm a bit afraid, it was really easy to unbrick Nexus with factory images, I read that someone had issues to restore system partition via TWRP. I hate so many ads anywhere, I want to use Substratum and CF.lumen :(
[Thinkpad Tablet General] zelect0r:
On the Stock Rom without a 3rd Party App is there no way to set a custom colour for visual notification.
[Thinkpad Tablet General] Ja_som:
Did you read that I use Light Manager and also tried it with LightFlow? But I still have only blue.
[Thinkpad Tablet General] zelect0r:
OK, my fault. But you have right. Only blue for notifies and red when connectected to power.
[Thinkpad Tablet General] Mr_Armageddon:
Were you able to find a solution? I recently purchased one off eBay coming from China as well since the US version is hardware gimped. Mine shows version TB-8704F on one of the sellers Screenshots.

[Thinkpad Tablet General] dywersant:
Bit late but...

This update is trash.

It does bump secutiry patch level to january 2018, and fixes a bug with wired headphones, but adds a dealbreaking bug with touch screen. Basically your screen will tap on its own, which is quite annoying.

I recommend you skip this version. I had do downgrade my tablet to previous patch.

[Thinkpad Tablet General] enigmo:
I got a TB-8704F to replace my Nexus 7. The good points:

It feels well built

It has a uSD slot and a headphone jack

The screen is swesome for a 8" tablet

It feels quick and nippy

The very, very bad:

It has now eaten three uSD cards; a Samsung, a SanDisk, and now a Lexar. Without uSD capability this thing is pretty useless.

A recent update has screwed its waking up, so if it's been left idle for a few hours trying to switch it back on results in the screen going haywire with dozens of small white dots appearing as if many fingers were touching it at once. If I do get to unlock the tablet, they carry on, selecting things at random. The only way out of it is to force a shutdown and restart.

In summary:

This is a wonderful looking doorstop right now. Thanks Lenovo. Roll on LineageOS.
[Thinkpad Tablet General] wavelet:
Re the microSD issue, definitely sound like a HW problem...

The model was only intro'd in July last year, so should still be well within the warranty period (at least a year globally, as far as I know). Did you not try and have it repaired/replaced under warranty?
[Thinkpad Tablet General] enigmo:
It definitely is, seeing as I've only owned it since around Xmas. I was hoping it was a software fix, seeing as some people claim to have seen better reliability from recent software updates, whereas I have not.

To be honest, if I could find confirmation anywhere this was a hardware issue, it's a widespread one and I wouldn't be interested in a repair. I'd want my money back to buy something else.
[Thinkpad Tablet General] wavelet:
Notification LED control?

(recently bought the Tab 4 10 Plus, TB-X704F, but there's no existing thread on it, and as far as I know, HW and SW are identical with the 8" version, aside from the physical size of the display).

I'd like to customize the notifications given by the LED via Light Flow or a similar app (allows setting a specific notification color per-app, control of solid/blink rate etc.)

I've been using Light Flow for years on Samsung phones, and wouldn't buy a phone without a controllable multi-color notification LED. It's less important on a non-cellular tablet, but would still be nice to have.

1) I can't find any documentation on the LED; I've noticed that without the app, it's solid red when charging / solid green when battery is at 100% / solid blue for at least some notifications (unclear which and when). Nowhere in the Settings (running the stock 7.1.1) can I find any mention of the LED.

2) Has anyone had any luck controlling the LED? If so which app did you use, and which settings in the app and/or Android OS should I look out for in particular? Is rooting necessary?
[Thinkpad Tablet General] wavelet:
I presume you're referring to this issue?

Annoying, because my pre-purchase research on major issues did not turn that up.

It does seem to have been widespread, although apparently one of the FW updates fixed it for most people. However, one of them still has it with a 10" model, like mine.

While I don't need the microSD immediately (I'm not in the US, and have one with 64GB built-in), I'll definitely need it later on. Returning an opened product isn't an option here, so I hope the problem doesn't show up -- I will try it with an older microSD I have lying around first, altho' it may not be fast enough.
[Thinkpad Tablet General] enigmo:
Yep, that's the problem I'm referring to. So far three firmware updates, three different brands of uSD card, and a little over three months have not resolved things. Neither has switching off Lenovo's logging to the SD card via the engineers menu.

I did the same as you and turned up no major issues, but being limited by wanting a decent 8" tablet my search was already restricted. In any case, in future I'll trust my gut and obvious problems or not, never buy Lenovo, and never buy a tablet or phone that doesn't have enough public support to earn an aftermarket ROM like Lineage.
[Thinkpad Tablet General] Ja_som:
Light Flow does not work for me, when I enable LF the LED flashes even when I have no notification, I also tried the root mode and also direct mode. But no luck. I also tried to contact the dev, but no reply.

For notifications the LED is only blue, you can't change it.

I had success with Light Manager, but you can't change sounds in that app, so I uninstalled it.

I have root and Xposed, so I use Gravity Box, where I can set LED (only blue) and also sound for apps.
[Thinkpad Tablet General] tmihai20:
Well, your argument is invalid. Community support is very fickle and does not guarantee that a device is worth buying. It is a nice thing to have, because we were disappointed by manufacturers so many times. It is a shame this is happening, but honestly we (people that want a good 8 inches tablet with a decent price) only have so little choices. I had the G Pad 8.3, I gave it to my sister, but the tablet broke for some reason. I bought a Mediapad M3 for myself and I like it. It does not have security updates, Huawei is either very slow at issuing updates or does not care about it. I bought the Lenovo Pad 4 8 Plus because it was recommended by some people and because some people went from Mediapad M3 to this tablet. I will ask my sister about the tablet and if she had updated recently.

Bottom line: there are no perfect devices, unfortunately. We do not have a lot to choose from, Samsung Tab S3 is a lot more expensive and I personally do not like the 4:3 ratio. If Mediapad M3 had regular updates, it would be almost perfect (it does not have fast charging). Judging tablets on community support is not the way to go. Mediapad M3 only has root and some tweaks here and there, but this tablet is the first that I did not feel like I wanted to root or change the OS.

Edit: my sister's tablet has the ghost touches too. She initially thought that the screen protector is to blame :( Damn it, Lenovo!
[Thinkpad Tablet General] enigmo:
Well, it wasn't meant as an argument, just for me a quite hefty entry in the Cons list when considering a new purchase. Fact is, community support can last long after OEM support has ended, and can resolve issues that the OEM simply doesn't care about. So while it is a 'nice to have', if you're not someone who can afford to junk and replace their tablet or phone every year, it ends up becoming increasingly important. I understand that I have been somewhat spoiled with my old Nexus 7, seeing as it's now six years old and I still have a choice of aftermarket ROMs and access to regular updates, and I don't seriously expect that again. But the availability of an alternative to the OEMs installed Android is just too useful to ignore.

I've not resolved it (I too suspected my screen protector, or the small magnet in the case flap), but I have found switching the screen on and off a couple of times using the fingerprint sensor can bring it back to sanity without a reboot.
