ROM Porting Rules for Xperia Play

hi.. I want to start porting some ROMS for our Xperia PLay
can anyone please let me know what rules do I need to follow..
I mean.. can we only port from armv6 to armv6 or armv7 also ??
can we port HTC One 4.1.2 to Xperia Play ?? Can we take the AOKP or CM10 as our base ROM .. and all other info that you may help me with.. thanks alot

Well we have a Qualcomm snapdragon s2 processor I believe its a msm8255 and adreno 205, so with that in mind the best bet on porting would be from devices with these specs and also same screen resolution.....and well if you wanna go from scratch and build a ROM then yea any ROM that is open source you can build from ( I.e. cyanogen mod, aokp, slim bean etc) I also believe our CPU architecture is armv7 and I do not believe that it is backwards compatible to armv6 and the HTC one has a Qualcomm snapdragon 600 processor with adreno 320 GPU so unless you plan to do ALOT of moding to a ROM from it I doubt your going to get it to boot

we need to find devices that have the same cpu at least for porting a rom
and gou is very important too
is there any samsung device taht has near specs to our device?
i wana port a rom from it
and its possible to port armv6 roms to armv7.

Maby try the sgs s1

galaxy s+ has the nearest specs

Xperia Play have Snapdragon S2 SOC. You can check on wikipedia wich devices have similar hardware (look under MSM8255).

I don't know if galaxy s will work because its REALLY IMPORTANT screen resolution is the same of that the device your porting from has a bigger screen resolution.

I am going to buy this Phone?

Currently I am thinking of buying this phone, or Xperia Z2. In Egypt they are very closely priced with the 820 at 3100 L.E and the Xperia Z2 at 3400 L.E and the difference is not going to be much. So, if I am buying the 820 will i be missing on so much ? is the 820 capable of handling the most hardcore games out there? and most importantly, is there any current (or incoming) developer support for the 820 (Root, Recoveries, Mods, Roms, etc) because this is one of the main reason i buy android phones.

Question before buy

Hello, i have a couple of questions and need help to decide if i should buy the LG G3 855 (BR edition) vs the Moto X Play.
Well, first off, independent of the phone that i'll get, i'll install TWRP and CM13, i can't have a phone without it.
So, is the G3 easy to unlock the bootloader (specially this version that i would get)?
Also, it's a 16gb of storage and 2gb of RAM (same as the Moto X play), but i have a huge question.
Is the SD 801 better them the 615 from the Moto X play?
How does CM13 run on that chipset too?
And last but not least... how is android dev going to this device, will it "die soon", or it's at full steam still?
Thanks

Only advantage of the Moto X play is that it's a newer unit compared to 2014 LG G3...
There's lots of tutorials here on how to unlock bootloader. I don't think you'd have trouble with it
SD 615 still can't match the 801 even if its octacore.
Aaand dev support is still solid and active.

Thanks M8, i was inclined to get the G3 as the only advantage of the Moto X play is the battery size.
But i heard that the in the G4 from my country, it is impossible to unlock the bootloader. As the G3 is, i'll get it

Moto Z Play worth double the price of Redmi Note 4?

Hi everyone, I'm looking to replace my xperia z3 which is dying and I'm unsure about what I should pick: Moto z play, Redmi note 4 or even Lenovo p2.
I'm looking for big battery (ofc), software, modding, audio, good screen.
Do you think Moto z play (320€) is worth double the price of redmi note 4 (145€)?
Thanks!

Depends on what lte bands you have near you (z supports us bands, redmi and Lenovo does not, I'm sure other countries use these bands), if you want stock software and frequent updates, front facing speakers, if you like Moto mods and swapable back covers, front flash, f2fs, good rom support, etc.

Ofcourse Z Play if between Note 4 and z play.
Z play has better gaming, quality,etc then note 4.
But for P2 and Z Play, P2 has more battery power/backup then z play.
P2 also have more higher specs then Z Play with- 4gb Ram, 64 gb storage.
But i personally prefer Z Play because of Premium look, mods and faster upgrades.(Even both phones are from Lenovo but Z Play will receive more faster Upgrades)
Cheers!?

AImark benchmark score half down in P vs. O - no Hexagon/DSP hardware support?

Hi,
Running AIMark (search for it im Play Store, I'm not allowed yet to post links) which also Anandtech uses for ML/DNN benchmarking gives me in Android 9 ca. 7800 points, only half of the score as when running it on another Moto Z2 device still with Android 8.0 where the score is almost 14000!
The benchmark uses the Snapdragon Neural Processing Engine (SNPE) for ML interference which can support DSP/GPU(?) acceleration. Without the required libraries from Qualcomm only the CPU cores will be used, which of course is slower.
The score for Moto Z(1) is with 13500 almost the same as for the Z2 what makes sense as both Hexagon DSPs 680/682 are quite similar. A newer 845 I tested (Sony, Android 9, Hexagon 685) has a score of ca. 19000.
In the Anandtech article (I can't link) the scores of LG V30 (835) vs. S9 (845) are similar in the same way. But a Pixel 2 XL, presumely without the Hexagon/DSP hardware support libraries looks really bad there.
Could somebody with an Android 9 upgraded Z2 try out the benchmark and tell me his/her score? This Chinese app wants access to calls and media (Maybe it only collects device name/IMEI etc. for statistics/ranking but who knows?) so be careful when you use it with your everyday phone.
If this is not a specific problem of my device then I guess the SNPE acceleration suffered a major regression for the Z2 (835) in Android 9 or some libs for hardware acceleration are missing .
Can someone else confirm this?
Thanks, M.
