Pipo M9 Max 4.2.2 RileyROM 1.7 with SDK 2.0

It should be mentioned that while you can install some apps to SDcard, not all apps will work like that. This way you still have the total 16gb "internal storage", but you "lock up" a bigger portion of this space, for installed apps (and their data), and an equally smaller portion is left for "user space".

An standard Android today, with for instance 16gb storage - will as rrileypm says, have 2gb of this space dedicated to installed applications. But with so much applications and games we often install, especially on tablets as they are more of a middle-way between smartphones and computers - this space is filled up quickly. It is possible to install /some/ games and applications to the remaining user space (SDcard) - but far from all of them.

The way to fix this problem is increasing the part of those 16gb, dedicated to installed apps and their data. That is what the parameter files does.

A sidenote: in an Android unit with internal storage (like this tablet, with 16gb) - if you have an additional physical SDcard that you can take out of the tablet, this is the /external/ SDcard. Earlier versions of Android and their phones, didn't have any /internal/ storage - other than that wich is dedicated to apps and data. Flash memory was expensive then, so all other "user data" had to go on an external SDcard - and it was up to the users how much to spend on external storage - if any. This is why, even though the free userspace that is left after a part is dedicated to apps and data, is internal and not removable - but still called "SDcard". When tablets and phones came along, with both internal free storage, AND an SDcard expansion slot - that external card was adressed as "external sdcard". Instead of changing the name, they added "Another layer to the storage cake". And following the hierarcy: Dedicated System/Data storage > Internal user space > External user space.

Thank you very much, now i understand
I would like to use it efficiently this tablet, how much space for applications would you recommend?
I was thinking just to 12GB because I'm going to take even a 32GB TF Card

How many GB occupies the RileyROM 1.7 when installed in the tablet?
thanks again

It is the total of all img files in the ROM folder.

really? wow
I thought a lot more once it is installed (such as Microsoft Windows that has a weight on DVD and install it requires many gb)
really good!
thanks again for your work and your kindness.
I look forward to the wifi only version

To be fair, windows and such is not space efficient (they have not needed to be since Windows 3.11). And, its an ineffective system as a whole (compared to linux, android etc). But it doesn't have to be - it usually runs on computers, with high-powered processors, big harddrives and other components that don't have to care much about how much power they consume - because either they are stationary (no battery) or laptops (huge batteries).

Android were made for mobile platforms; - small, limited resources, limited small storage space, small power source. Because of this - android is very quick, power efficient and takes little space.

If you don't think you'll flash new rom very often, you will most likely acumulate apps and games more than users like rrileypm and me. If so, I suggest you go with the 4 or 6 gb parameter. Its no point in taking all internal space for data/app space, unless you have other reasons for doing so. But if you don't flash often, maybe only a few times during the tablets lifetime - 2gb is likely going to be too little soon.

Keep in mind; you cannot change the size of this space without flashing (again).

thank you for the additional information
I'm learning a lot and I am grateful

That is what we are all about here at Freaktab. My pleasure to help.

While we're in this topic, I remember reading somewhere on this forum that one can use the 12GB parameter to enlarge the app space, and later on swap mount the rest of available user space (~2GB) with the external SD card. That way, we can have plenty of space to install apps, and at the same time can utilize the external SD card better since whatever the system store on the internal SD card is really stored in the external SD card now. Well, at least that's my understanding of it . So my questions are:
1. How can we achieve the above scenario?
2. What are the disadvantages of doing so? I imagine Android will throw an error/crash if the external SD card is removed while the tablet is on?

No3G Version?

Hello rrileypm,

is a NO3G version planned ?

Thanks for information.

Best regards

The disadvantage I see is that data exchange on the external SD will be slower, and must rely on a good SD card. You might take a performance hit, especially running games that save data to the external SD.

I'm sure you can google the instructions on how it is done, if you want to try.

If you prefer it that way, live it up. You can always switch it back if you don't.

I'm sure Pipo is working on a wifi version of this firmware, but I haven't seen it posted. As soon as I get a firmware to work with, I will do one for wifi only.

If the card reader interface isn't a bottleneck, you can get SDcards that is /much/ faster than internal memory. My 32gb sdhc sandisk ultra class 10, when used in the m8pro - is reading a bit faster, and writing DOUBLE the speed of the internal flash.

For the M8 pro, I've noticed that the only difference between the 3G and wifi version are the file app/phone.apk and lib/libril-rk29-dataonly.so.

Really that's why they are vary much interchangeable. Except for the 3G feature.

I wonder if they are the same files as the last rom.
