just to let ya all know --- there is a possibility to install aptx codec for better audio quality --- you need to have a custom recovery (we have it) and flash a zip that is provided here in the forums.

Just search for AptX Nougat on XDA. I must say that if your device / headphones / speaker supports this codec then the audio quality is definitely better.

Still doesn't solve the problematic BT handshakes (actually I had only one, took me 30 seconds to solve it via disabling/enabling BT and reconnecting), sometimes doesn't reconnect automatically -- need to force connection -- but afterwards --- all good and no biggie.

I ordered a voyo tempered glass screen protector at aliexpress. It fits very well.

But my only problem with it: it seems the screen of my voyo is not 100% straight. On the corners and the sides of the lcd the tempered glass has air under it. And at the border of the tablet, it fits again. So i thing the place where the lcd meets the white border it is slightly deeper then the rest of the screen.

Anyone encountered the same problem? I can´t get the air away from this place. If i move it to the outside with my finger, it comes back again a second later.
[Android Q&A, Help & Troubleshooting] goofer22:
Hi,

I have exactly the same issue with the glass from aliexpress, it fits perfectly from a size perspective, but does not apply to the screen completely. I also did not find any way to get all air removed :(

Unfortunately, nobody answered to my question on the Q&A section, but maybe someone will help me:

Is it safe NOT to flash the newer preloader (which comes with Android 7.0), when upgrading the OS (from 5.1), and thus, using the older one ? I really do not want to hard-brick the device, but I am not sure if it's ok to ,,mix them" - to UNCHECK the preloader (when flashing the new firmware) ...
[Android Q&A, Help & Troubleshooting] _PrEzi_:
IMHO no, you need the new preloader.

I would say that it is far safer to flash the whole ROM as it was meant by the manufacturer than to experiment with partial flashes.

It's not necessary (to reflash the preloader) when staying within the major version (e.g. 7.0 -> 7.1 / 7.1.2) but not when changing from 5.x (6.0 is also a fake 5.x) to 7.0.
[Android Q&A, Help & Troubleshooting] rauliordache:
I want to try a partial flash of 7.0 (from a back-up posted on this topic), on my 5.1 VOYO (without staying scared about that f*cking preloader which could "RIP" the device). Hmm ...

I have no problems with my actual 5.1, but I need API24 for programming purposes....

[Android Q&A, Help & Troubleshooting] starbright_:
Do they have same hardware? I mean the device with Android 5 and 7?

From my experience it is complete unusual that same hardware is supported (by these kind of product) versions that are so far away from each other. But maybe SOC-producer did this in this rare case.

Could this version (with 7.0) be rooted and is TWRP available? Please let me know, once you have done that (and how).

Hello together,

i have the voyo since this summer. Version 6.0 with the newer screen revision (flickering with old firmware)

But now finally i have rooted my device. So i want to share it.

SD Card with following apps:

Kingo Root

TWRP & Supersu from jemmini

jemmini@4pda.ru:

http://www98.zippyshare.com/v/pmdfU3Y/file.html

I have flashed with sptools the screen revision firmware 6.0 from 4pda.ru to have a clean system. But i dont think that is a must have.

1. Install Kingo root -> root

2. install flashify from play store

3. flash twrp from jemmini with flashify to recovery (twrp 3.1.1. dont work on my tab)-> restart

5. flash supersu.zip from jemmini with flashify

6. delete kingoroot and his own supersu programm (not systemapps like kingroot which are difficult to delete)

when supersu is not working

8. install kingoroot again -> root

9. flash supersu.zip from jemmini again with flashify

10. delete all kingoroot apps

For me it works.

Rooted Voyo with adblocker. Perfect.
[Android Q&A, Help & Troubleshooting] rauliordache:
Yup ... today I've flashed mc_seem's ROM 7.0. And it works!

So, the second revision of display - it's a Samsung display (the other one is Huawei) - works with mc_seem's 7.0 seems. After 2-3h of playing, I've no flickering, or other issues.

The battery problem exists (veeery slowly discharge from 100-50%, then a huge drop to 1%). But I hope that a calibration or some mods into the firmware will "cure" this problem. I have to mention that

i didn't have this problem with the previous 5.1, stock ROM

. All in all, this upgrade is a big +, despite this problem.

Now, I'll sum up the procedure of upgrading from 5.1 to 7.0:

1. Firslty, I took a back-up of the entire system, including nvram, nvdata, userdata, etc.. For this, I needed to create a scatter file containing the address blocks for each partition. Unfortunately, MTK Tool

does not

work good with MTK 67xx. Wrong blocks, wrong partitions, unable to create scatter file, etc. So:

1.1. You have to modify manually the original scatter file (take the MTK6753 scatter from the second revision, posted on VOYO's website) using Miracle Box (M.B.), which works, again, just partially. You will use the M.B. just to see the block addresses and sizes for each partition, in order to modify the scatter. Do not use it in order to create the scatter, coz it will fail!

98% of the scatter will remain the same (it's logical), but userdata and cache partitions could have diff. addresses. Verify entire scatter... it's 10 min!

linear_start_addr && physical_start_addr should have the address pointed by M.B in the "Addr" col

partition_size should have the size pointed by M.B. in the "Size" col (see pics)

1.2. Now, using SP Flash Tool + doc. from XDA, you can take a full back-up of the entire partitions. The most important: nvdata, nvram, userdata (maybe). These are device specific partitions(+ your data). The others, also important, are posted by VOYO on their website. But,... just for sure, take a full back-up :). SP Flash Tool, read back, ... etc. It's easy, use any tutorial.

1.3. We are ready to flash mc_seem's 7.0 ROM. Open SPFT, point to scatter file from mc_seem's archive, change to firmware mode, not the download one, then click download (button). Connect the powered-off tab, wait 10 minutes, and you should have 7.0 on this f*cking tab.

Now, I'll root it.

For those who can read Chinese (or is happy to work with Google Translate), the Voyo Chinese site (http://www.myvoyo.com/xiazai/anzhou/Q101/down/) has posted a new firmware writing tool package which includes a SN writing tool in addition to the usual flash tool. This SN writing tool can apparently write/repair IMEI, BT, WiFi and several other parameters. Maybe useful to those who has the knowledge to use it.

The site also has a link for a new firmware dated 14/12/2017, possibly the "real" 7.0 that is on recent tablets, but the link is currently empty. Hopefully they will upload the file soon.
[Android Q&A, Help & Troubleshooting] rauliordache:
It sounds great!

Btw, some people have found the problem with battery on 4pda. The problem stands in the LiPo (LIthium-Polymer) battery combined with the Android OS.

Android OS is set to show a linear discharge, based on the LiIon format.

So, there is not a problem with the firmware (it is, but not how we are thinking), nor with the battery itself.

LiPo voltage VS. Capacity

What I wanted to get at is that in RC we ALWAYS use voltage to determine remaining capacity. The voltage is, as most likely already know, proportional to remaining capacity between 3,6V (empty) and 4,2V (full) per cell.

This means that volt/capacity can be measured as: (per cell)

4,2V = 100%

4,03V = 76%

3,86V = 52%

3,83V = 42%

3,79V = 30%

3,7V = 11%

3,6V = 0%

approx 3,8V = storage

This measurement works in 99,99% of cases. Only known cases I know where method fails is if a cell suddenly breaks.

Source: https://forum.dji.com/thread-33867-1-1.html, #18

So, a little change in the firmware (I'll try these days) OR a custom app to show the real % (it's a simple app!) based on the Voltage, is enough!

All devices with LiPo (or other battery types than LiIo) are in the same situation. So it's not a specific bug for VOYO.

====

Now, I want to root it (using TWRP + SuperSU), without wiping the data partition (even though the IMEI is recoverable via the full back-up I've made). Any ideas? I read that wiping data partition is a must, as long as the device will not boot until this step.

Look at the boot.img, cache, recovery, and - the most important - system image. Also, the userdata is not the same (so, there are some new apps maybe).

I wouldn't worry much... might be that mc_seem ripped a bigger (than needed) area of the internal storage, which was e.g. empty/not used.

Hi all, new to XDA so please bear with me I'm not programmer :)

I bought the Voyo i8 plus, which seems good for the price (nice screen) but didn't come with google play installed. Tried rooting the device (no luck with the well known 1 click rooters) and I'm not confident enough to try and do it by a manual method. I'm reasonably tech savvy but not a programmer...

I tried installing Google services (via apk downloaded from apkmirror) but even with their descriptions couldn't seem to find the right version of Google Play Services (just continuously crashes whichever version I try...440 and 430 seemed like the most likely, but neither worked)

Thus the tablet is extremely limited at present, then I noticed there's a new official ROM available, which states it has Google Play Store enabled. Available from their official site, can't link as I'm a new member. en dot myvoyo dot com

Only problem is I've no idea how to install it, I've copied it to the devices root folder (as a zip, as downloaded) and tried starting the device in recovery mode, only to be confronted with chinese language options (tried google translate but that didn't help much). Can advice how to install this for an amateur in the android modding sphere like myself?

Try the following (from: https://www.apkmirror.com/?post_type=app_release&searchtype=apk&s=google+play )

1. First, try to get (and install) Google Play services 11.9.51 (1st Jan)

Video streaming + WiFi around 5-6h. With lowest brightness.

The usable range is between 100%-45(50)%. But it drops slowly. After 45%, huge drop.
