so i saw that the apple a7 chip is actually just a snapdragon 800 processor just like our nexus 5, does that mean the nexus 5 kernel does support 64bit?

No, it doesnt. The entire system has to be optimised for 64-bit and not only the chip.

Android wouldn't really need to be optimized for 64-bit like the iPhone 5s because Android uses a virtual machine (Dalvik) to run apps, whereas iOS runs applications natively so those applications would need to be optimized for 64-bit.

just FYI , right now 64bit on iOS is a gimmick , notice i said " right now" ... dont you find it odd Apple never mention specs ? didnt tell us what the CPU speed was , how much ram... but all of a sudden , they tell us its 64bit architecture? hmm

Incorrect. Much,much, MUCH, of android is native code (even the dalvik interpreter), which is dominated by ARMv7 architecture at the moment. With the transition to 64 bit ARM (AArch64 mode on the ARMv8 processor), the kernel, drivers, bionic libc library, libgralloc (graphics), and countless other libraries need to be ported to 64 bit. This involves 64 bit compilers becoming release quality, and code reviews to ensure that pointer casts are handled appropriately for the transition to a larger address map.
However, there is nothing inherently better about '64 bit' and the Snapdragon 800 chip is a monster.

Learn something new every day But the apps themselves on Android wouldn't need to be re-written for 64-bit like they do on the iPhone 5S, right?
Back to Apple's A7 chip, I think Apple did this to get a head start on 64-bit development; I doubt the iPhone 5S has 3.5GB+ of RAM so 64-bit doesn't seem practical for the 5S.

Yes and No. Some Apps (most Games) run native code the would have to be rewitten in 64bit.
I think it has been confirmed that the 5S has 1GB of Ram.
64-bit is meh.. its going to take time for it to mature. Its still in its infant stages and will take time... but eventually down the road, it'll become the standard. For now, I don't think its that much of a thing to look at when buying a phone.

Yep. In fact, the best thing about 64 bit is the ability to see a 4GB+ memory space. ARMv8 does a nice job of cleaning up the instruction set (I spend my days writing ARMv8 right now), but I expect power to be an issue even at the cost of possible speed improvements due to doubling neon/VFP registers and other such improvements

This...
If the addressable mem space (RAM) goes unutilized, the cleaner instruction set remains the only pro. For now, gimmick.... Down the line, standard.
booooom
A7 is not by any means close to a Snapdragon, completely different designs. But similar performance though.

I actually have a P8000 but it doesn't have a gyro. I would like to develop android app with Unity for cardboard.
Which phones are actually the best ?
Must have : gyro, 3gb ram, 1080p, 3000+ mah, if possible support with clean drivers, if possible android 6.0 if not 5.1, max 270€ (300$).
Thank you

I fond it in amazon india but i can't import it in my country. Any other ideas ?
So does anyone know if huawei is affected by the newest cpu bugs?
Seeing that ARM states that cortex a72 is affected, kirin 960 is almost definitely affected.
as i know, kirin 960 meldtdown=no / spectre=yes
Every month it is some other security breach... I am losing hope in technology.
The question is: when we'll have a tool to check devices (both mobiles and PCs, any OS) for these vulnerabilities ?
EDIT: the mighty Alex Ionescu (ReactOS) published a Windows utility !

Month? Lol its every day. Just be glad you aren't tuned in to security, it's absolutely mindwracking
I would strongly suspect the answer is yes, but can anyone check that the OS on the One Vision is the 64-bit version of Android? I ask because Motorola has put a 32-bit OS on some phones with x64 CPUs before such as the Moto G6.
You should be able to check buy using an app like AIDA64 under 'CPU>Instruction Set' it should say 64-bit and not say anything like "Running in 32-bit mode" or using the Antutu Benchmark in 'Info' it should say next to the Android version '32 or 64-bit' as well as it should be able to run 64-bit only apps like the Dolphin Emulator.
Many thanks in advance

Looks like it does. Check out the screenshot from my One Vision.

Thank you, with Google pushing to 64-bit apps and eventually going to phase out 32-bit apps I wanted to double make sure as I keep my phones for a long time (currently still using a Moto G2).
Hey everyone !!!!!!! Do you know any PS4 emulator for android. I searched on Play Store and got one but it has bad reviews. I searched on Google and got some apps but who knows if they work or are safe. Please provide me an apk if you know one which works and is safe.
THANK YOU !!!!!!!
Hi Arc,
I strictly doubt that any ARM based processor (except for the M1 by Apple) is capable of emulating PS4 in real time performance.
Therefore, there are no good apps for this, and if there are - you will likely have severe performance issues.
Most PS4 based operations are done with the help of a x86-64 architecture, which you mainly find in desktop-grade CPU's.
Which phone do you have?
Picture below is gotten from pinterest.com and reflects the specifications of the PS4.

None of the specs match to my phone (Lenovo Tab 3 10 plus) so no chance. Anyway thank you for reply !!!!
