    I have held and played for a bit L640 and L640XL, both are great devices, both feels awesome in hand (Even tho i adore my ATIV S i8750, wp8.1.1, I have to admit that it's not a good device to hold it in hands, it's slippery, while 640 and 640XL are not). This is one of the feature where 640/640XL is beating the ATIV S. Anyway, for comparison sake, let's compare ATIV S with L640.

    In my opinion here is where L640 is better than ATIV S:
    - It have bigger screen (5") than ATIV S (4.8"), both 720p, altho in pixel density ATIV S is better cuz of smaller screen size, but the difference between 5" and 4.8" is not that noticable. L640 have 294ppi and ATIV S have 306.
    - It have better CPU than ATIV S. L640 have quadcore QSD400 which is slightly better than ATIV S's dual QSD S4, altho the L640's cpu is clocked at 1.2GHz and ATIV S's on 1.5GHz
    - It have better GPU. L640 have Adreno 305 versus ATIV S's Adreno 225
    - It have better support than ATIV S in the Micro SD department. L640 is supporting up to 128GB SD Card versus ATIV S's support up to 32GB (altho I have heard with the new and latest WP8.1.1, ATIV S can support up to 64GB, but i am not sure and if someone knows better, please correct me)
    - It have bigger battery than ATIV S. 2500 mAh versus ATIV S's 2300 mAh (keep in mind that IPS LCD are less battery hungry than Super AMOLED screens, but Super AMOLED screens are more battery efficient when you use full black backgrounds).
    - It have Gorila Glass 3 versus ATIV S's Gorila Glass2

    In my opinion here is where ATIV S beats Lumia 640:
    - Better pixel density which means more clear view on the screen.
    - It's slightly smaller than L640, which means better feel in hand.
    - It have Super AMOLED screen versus L640's IPS LCD. In my opinion Super AMOLED screen are doing better justice to WP UI and it is better pleasure to look at the screen than on L640's IPS LCD even if its Clear Black technology. Clear Black is not Full Black.
    - Bigger internal memory (16/32GB or 13.5/19.5GB user available) than L640's 8GB (6.5GB user available)
    - Better front camera (1.2/1.9 MP, depends on the model) versus L640's 1MP.
    - It have dedicated physical Camera button, where :640 (or L640XL) doesn't have.
    - It have more sensors than L640. ATIV S have 4 sensors (Accelerometer, gyro, proximity and compass), where L640 have just 3 (Accelerometer, proximity and compass) it lacks the Gyro Sensor, which is very important one and lot's of apps are taking advantages of it.
    - It have combination of 2 capacitive buttons and one physical Home button, where L640 have on-screen buttons. In my opinion I like it more the ATIV S combination of the buttons because with the capacitive buttons is less fingerprints on the screen and i can wake my phone from the On/Off button on the side and with the Home button bellow the screen.

    Conclusion:
    Specs wise L640 is better (cuz it's newer) device than ATIV S, but there is no significant changes or upgrades that will make any previous owner of the remarkable ATIV S to switch to L640. Or if you like the looks of L640 better than the ATIV S, then that is one reason to replace your ATIV S with L640. Altho in my opinion ATIV S have unique design and it looks better than L640 design, but that's just my thought. I will not switch my ATIV S for any of the L640 or L640XL, cuz i love too much the damn phone and on top of that it is on the schedule to get WP10, so... you do the math.
    On the other side, L640 is a perfect device to start if you want to switch to WP from some other OS. Or if you come from lower specs Lumia device (like L520, L530, L630/635, etc.). In that case L640 is a worthy upgrade for the one who doesn't want to spend too much money or is budget limited and to get a good phone with decent specs.

    I am sure i forgot to mention some other stuffs, but in general this is it, :) I hope this helped to some people wondering should they or not switch or "upgrade".

    Cheers.

    I have a Sanmsung Ativ S. It has been my main mobile phone for 2 years. Recently I have bought a L640 for my mum. In my opinin:

    -The performance of both phones are quite similar. L640 is better in multitasking while Ativ S is better in single thread since most apps are not optimized to take advantage of 4 cores the ativ S looks faster in my hands.
    - The camera of the Ativ is better, even with low light. I ve read that the L640 XL has a better camera but im afraid the L640 isn't so good. Im not saying its bad, just that it cant match the quality of an old flagship as the Ativ is...
    - The size is on the Ativ side to... its smaller and looks more premium, the L640 isn't very different from my dad's L535...
    - The screens are similar, ativ amoled is better with dark screens while the Lumia displays whites better.
    - The Lumia 640 lacks wifi 5GHZ, some sensors and camera bottom, but has glance, senso-core and all the Lumia software.
    - The Ativ S has 16 GB storage vs 8 GB of the Lumia. And a better nand flash since the internal storage transference are much faster...
    - The Lumia 640 enjoys MS support and is updated to windows 8.1.2 out of the box. While only some Ativ variants have 8.1.1 and you have to mess with your phone to get the 8.1.2....

    All in all, if you are going to buy a new mobile phone, and you can get both devices for the same price is hard to say which one is better. However in most countries the L640 is cheaper and buying a second hand Ativ for the price you get a new L640 is hard to recommend. I must add that upgrading from an Ativ to a L640 looks like a stupid thing unless the Ativ is broken...

    i would prefer 640, simply because now in the summer ativ outside in the day, with sunlight is very difficult to see. I think (not tested by myself) 640 is better.

    Seems like L640 is actually a downgrade, based on comments and specs. I think I'll pass on it, althought I woukd have to pay a small defference (~20 euros).
    Thnaks everyone for comments. I'll have ti wait more.

    Adreno 225 is better than 305, I done a benchmark with my brother's 640XL, I got 19fps, him 13. The same with same benchmark on an Android device with S410 and Adreno 306, only 13 vs 19 of my ativ.

    640 could be better in sunlight, but Ativ S screen is simply beautiful by itself and not difficult to read at all.

    Agreed, I compared the screen on the 630 my mum has with my ATIV S in Facebook Messenger and you could tell that the 630 screen looked washed out.

    Yes, ATIV S's screen can be real pain to watch it in direct sunlight or outdoors with lots of brightness, but guess how i solve that problem? Simply, I ordered a high quality anti-glare screen protectors, problem solved :)

    I found something interesting, AIDA64 states that the ATIV S has a SD S4 Plus MSM8960 in it so we have BT4.0 and LTE Support.

    I am surprised you didn't know that so far? Yes we do have that but i guess we need to be interop unlocked (guess that's the level we need to tinker with the Registry?) and i am sure that the bands for LTE are there but we somehow need to find the registry that enables that. Someone with more WP hacking knowledge please correct me if i am wrong. So far I think grozaman can try this on his ATIV S since mine is still not interop unlocked.
    But for the sake of confirmation, I will check if AIDA64 will say the same for my ATIV S too like it said on neo's ATIV S.

    Doesn't t899m variant have the LTE support?
    06-08-2015 05:25 PM
  16. grozaman's Avatar
    No, T899M and I8750 have different chipset (some guys already checked this). So there are no registry hacks to enable LTE on I8750 model. BT4.0 theoretically there, but it's hardware disabled by Samsung. Samsung can probably activate it, but apparently he's too lazy :D

    Just a note: Even with the Interop Unlock, you cannot edit the entire registry. Often, the main system partitions of registry can be edited only by using customs. So it's cause the problem to test quickly.

    Ok, I just did a test with AIDA64 and here are the results:
    (I scale down the images but the image of all test screen together got big again)
    However, it is too bad that we have the CPU but we cannot enable the LTE, what a shame...
    Anyway, grozaman, what kind of unlocking level we need to get the registry we usually cannot? Developer unlock or Full Unlock?
    Ok, here are the screenshots from AIDA64 from my phone put in one picture:

    Ativ S has BT 4.0 enabled from Windows Phone 8.1 update because it can be paired with Fitbit and BT 4.0 heart rate monitors.

    Really Kaunaz? So, I have on my own the latest WP8.1.1, so that means mine is already enabled? Wow, that's nice to know.

    maybe after w10 update LTE will be enabled
    If I understand grozaman, we have on our i8750 ATIV S's a different chipset where LTE doesn't exist.

    mine with auto brightness, but even with brightness locked to high, is very difficult to see in strong sunlight condition.
    It's not a problem og flare, but the amoled brightness. Sure, i'0m very myopic, maybe for others the problem is lower but... I think for everybody is more difficult.
    I prefer i can easily to see everything than better color or similar.

    Oh I knew that so it was more for the benefit of those who didn't know. LTE would be difficult to get working for several reasons, it might be disabled in the firmware or on the SoC itself not only that I would guess the antenna we would need is missing as well. Also the MSM8960 has support for LTE but chances are that it's disabled in the SoC rather than firmware.

    Go check the specs for the SD S4 Plus MSM8960, the SoC in the i8750, and you'll see that it DOES have BT4.0 which was enabled with WP8.1 as you can pair BT4.0 devices to it. LTE would be in the SoC itself but disabled as the relevant antenna isn't in the i8750.
