Hi [MENTION=7269564]chin_bone[/MENTION]

Hate to be the bearer of bad news for you mate, but this is common with out tablets, I have had this issue and so has....well... Lets just say a hell of a lot more.

The Issue is spread across three things typically:

1. Battery is dying, whilst you can run programs all you want and they will say it is in good health. Once that vlotage drops too much, the screen will begin flickering, and then at or near 50% or 30% power it will shut down

2. The connect at the battery terminal on the motherboar has cracks on the solder, this is also part of the problem, which I soldered myself but would highly recommend you get someone who has the right soldering iron or it wil get butchered like mine

3. The battery connector issue extends itself to the otherside of the motherboard, this is where it starts to get a bit painful as it increases the work needing to be done

Suggestions:

* Buy a new battery of eBay, they range between $20 -$60 depending on whether it is fake or genuine, to be honest I have tried both types and they work much the same. This will overcome the cracking issues for a little while as the voltage in the battery will be strong due to the health of it, but typically it will return within a few months due to the constant shorting out

* If you know someone who can solder, and they have a fine tip soldering iron, get them to fix it up for you (They will need a powerful magnafying glass as everything is so tiny, and you cannot easily see the craks or the solder with the naked eye

* Bend yout tablet a little so you put some pressure on the connector and the PCB board, but this is very temporary fix and also dangerous as you can damange the screen if you dont know how much pressure to apply

Sadly there is no ROM that will fix this probelm up for you as it is a physical issue that is widely reported and if you look on XDA further you will see some of the other guys have posted picture of the exact issue.

Cheers,

David.

Hi [MENTION=4465682]kb8no[/MENTION]

Yes you are gith, Nougat has this funtionality removed.

It is now located at "Settings > Display > Scroll to the bottom and you will see "Display Size" and this now kind of replaces that feature, al beit crippled.

I have no ides why this was done by Google an it made no sense to me, but these are the only options we have now, we cannot even change the DPI settings which sucks badly.

Cheers,

David.

Hi [MENTION=5230113]killerjay[/MENTION]

Yes there will be, and there will be one almost every week movign forward most likely as the team will work on this continually.

The majority of the updates can be dirty flashed, unless either myself or [MENTION=4817899]thompatry[/MENTION] advise that it will require a clean flash, the updates are quick to do.

Typically I will advise if a clean flash is required after I have done a series of testing on the ROM before it gets released, I actually always test it with dirty flash first, see how it runs for a bit, and then do a clean flash and see how it runs after that, then draw a conclusion as to what will be the best user experiene.

However there are typically routines that need to be done to ensure a good clean dirty flash, if those routines are followed then the user experience should be pretty well suited.

Also after any major updates are release, you should always do a clean flash regardless as the fundamental base of the system has changed, and once the clean flash is set back up properly, you then proceed to do a backup in TWRP in the event you want to do a relfash at a later point, but you dont do the TWRP backup untill about the 4th day as you need to give the ROM some time to settle after the upgrade, and you always clean the cache/art/dalvik before a backup as well.

Cheers,

David.
