For an application we need to toggle the flash LED of the mobile as fast as possible.
In a for loop the flash LED is toggled 100 times.
We noticed a 4 time speed difference between different devices running the same Android version (version 9).
What is strange is that the device with higher specifications (an 8 core Samsung Galaxy J7 duo) performs 4 times slower than a 4 core device made of a different brand. (both devices have similar clock speeds).
Note that both devices were brand new "virgin" devices with no apps installed on them.
Can somebody explain this difference ?
@Ridge dewaal
The amount of CPU-cores tells nothing about how well/fast a device performs. Note that the primary core is the rate limiter for an application.

Not exactly relating to the Nexus 10, but it is mentioned in the article and how supposedly this new processor can cut power consumption by 70% compared to the processor in our tablets:

Would be nice if a new model of the Nexus 10 (or 11?) could be based on this.
Hello everyone,
I'm looking for information. I have the current use case:
My smartphone is a Sharp Aquos Zeta SH-03G with lollipop 5.0.2 (I didn't get a choice on the device I could get )
By digging a bit in the system I found out that this smartphone is configured somehow to not use the full CPU capacity. It justs use 5 cores out of 8 of the snapdragon 810 whatever the activity on the phone.
However all the core are seen as possible to use by the kernel with correct frequencies.
Only the core up to 1.5Ghz are use normally. for the core up to 2Ghz, only one is used and not at the top frequency (max 1.4Ghz)
Which make this phone to act as a 5 core up to 1.5Ghz. I'm just curious to understand where I should look like to see where that configuration is done.
Is it in the custom kernel source code? Is it some arguments given at boot time? Is it in some configuration file somewhere on one of the booting partition?
They release the source code of the kernel so I just give at least a quick check in the processor core frequency definition for a snapdragon 810 and it was looking like all is defined approprietly to use all of them. Also the system report that it really see 8 cores and that 8 cores may be use if needed...
Any help appreciated, thanks!
Hi! Guys
I have some weird problem. I have two of this device bought it from different shops. both RN3 pro 32 gig.
but when I check the hardware in antutu for one of these says:
CPU model: 6 Core ARMv8 Processor (VFPv4 NEON)
and for the other one says:
CPU model: Qualcomm Snapdragon 650 MSM8956
both have adreno 510 GPU
results of the first one was 66000 but the second one 76000!
also the Light sensor of the first one is from Liteon and the second one from Sensortek!
besides I see the color accuracy of the their screen is not the same both in same sattings
Please check your device if it's possible and help me out to understand why they have these differences! is it normal?
Not sure but it looks like you might have an mtk version and a snapdragon version
don't worry, it's the same processor.
first pic is the result of antutu not being able to verify exact cpu model cuz your device isnt online. however, what it reports corresponds to 650 anyways. try and go online, it'll show the real name. as far as benches go. heat, rom, usage could affect scores greatly. i wouldnt worry about it.
oh and as far as sensor goes, yeah, xiaomi made several rn3 "versions" with different fp/light/camera sensors. who knows what else was changed tbh. prolly cutting costs after pushing "higher quality" devices in the first batch and gaining some popularity for the device
Completely normal, nothing to worry about.
1. Dont rely on Antutu scores, they are inconsistent everytime. Both of your devices are original running on Snapdragon 650.
2. Xiaomi uses internal hardware from different manufacturers ranging from sensors, camera modules, RAM, display panels etc.
3. Same as above, both devices have display panels from varying OEMs calibrated differently.
thanQ all. Now I'm relieved
I have another issue that I don't understand! in recent apps, one of the phones shows the recent apps with the apps last image, but one of them shows the apps with just its icons! although both are running with 7.3.7 global stable! is it a hidden setting or something about it?!
double finger zoom in/out if i remember correctly
Most manufacturers use parts from different suppliers, like xiaomi. None of it is better or worse than each other. The display seems different because SHARP panel is "cooler" and BOE panel is "warmer". That's just how the manufacturers of the displays calibrated them.
Hi there
I'm trying to achieve the best bandwidth over wifi which i need for local file transfer, but strangely enough my Redmi note 4x (Mido) can't get any higher than 150 Mbps link speed over wifi.
My router Asus rt-ac3100 can handle way more than that.
Looking at SD625 specs reveal that the SOC can peak up to 364Mbps.
I used a bunch of 7.1 and 8.1 ROMs but they all have the same results
So i'm wondering what is the limiting factor, and if there is anything to bypass it
The phone's WiFi chipset only supports N bands. It's a/b/g/n only. Though you'd think it'd connect a bit higher, since N allows for 600Mbps. My laptop is stuck with an Intel a/b/g/n card and I get a link speed of 240 to 270Mbps when connected via 5 Ghz.
How far away is your router? My router is in my room, where I am right now with all my devices. Though the link speed on my Note 4 is still capped to 150Mbps. Strange. Don't know if it's a fixed hardware limit or something else. I previously checked on MIUI and now on LOS 15.1. Both show the same 150Mbps link speed.
My LeEco x722 (SD820, 802.11ac WiFi) got 866Mbps easily. I also had another Snapdragon 625 phone, but with AC WiFi. It too got a pretty high link speed of around 600Mbps. I think the issue is that the wireless chipset in the Note 4 is very poor.

The router is in the same room as i am with no obstacles between.
I found (at gsmarena.com) that Mido only support up to wifi N (no AC) even though the SoC support AC standard, probably due to the implantation of cheap radio hardware, and because most phones optimized for efficiency it run only on a single radio band that is why 150Mbit and not the 300/600mb advertised even for wifi N standard.
The news left me disappointed, for a top midrange phone not to support AC, i guess something to consider in my next phone
The twin brother of mido the Mi A1 which is literally a Redmi note 4x play edition support AC wifi. Moreover the Mediatec version (nickel) also support AC wifi, so why xiaomi left the redmi note 4x without?
The more i dive the more i feel betrayal.

I believe it is a driver from the firmware and/or kernel that doesn't allow full speed N or AC to work. I have looked into most of the software and cannot find what is stopping it.
Try wired connection by buying usb adapter maybe? Have you tried flashing latest dev firmware along with rom that might help.

Wired connection is not an option for a phone. I tried both stable and dev firmware with a bunch of roms and it is always the same 150 Mbit link.
Gsmarena listed the phone as Wi-Fi 802.11 a/b/g/n enabled device. So it it official, no AC for mido
Im using samsung galaxy m30s mobile it comes with os one ui core
But all galaxy mobiles except m series has one ui
One ui core does not have all feature's like one ui it has limited features its lite version of one ui
And the major problem is one ui core doesnot support knox ,good lock and many other great apps which was used for customization.
So finally i want to change my os from one ui core to one ui
Does anybody knows how to change...with root or without root any solution....
There is a reason why OneUI Core isn't being provided to such mid-range smartphones. OneUI has a horde of pre-installed applications and hardware based features which require a high configuration of RAM, GPU and CPU. Only Samsung devices equal to or higher than A series are provided with OneUI "non-Core" because their hardware is suitable for running it. Anything lower than that has OneUI Core.
But, but, this isn't the end of it. Many devices have developers that provide custom ROMs that allow you to basically wipe OneUI Core and install OneUI. You can have a look at M30s XDA forum.

Not really, no. Samsung A10S from A series which I have, has One UI core.
And high configuration? Check out A32 and F22, Same chipset, same ram and rom combination, yet, A32 contains One UI and F22, which is just another version of A22 with varying battery capacity, both of which also contain One UI core.
It's not about series or letters, it's about the numbers.
