I see a lot of complaints about OP3/T not utilising more RAM ?
Well, I hate to break it to you guys, but that was true for a few weeks after the launch. After the update, 6GB of RAM did wonders to me and my multitasking. And even without that update, you could still use all 6GB without any issues with a really small and simple fix from xda.
I am sure that OP5 will use those 6GB from the start. OP3/T proved to be best Android device when it came to holding apps in background. And not just by a small margin, but with a really great margin. And I am sure OP5 will do the same.
But saying that, I am rather sceptical about 8GB version. I have nothing against adding more RAM, but 8GB is a overkill, and if they allow all of 8GB to be used, then the battery life won't be so great. So I do consider 8GB to be a complete marketing gimmick.
But the thing that interested me the most is UFS2.1 dual channel storage. Read/Write speeds on OP5 are insane, even when compared to current flagships. So faster installs, faster app loading times, and faster swapping (if this is even needed on a 6/8GB phone).
2 have been already ordered, but not by me, but by my friends. I will first see how they feel in my hand, and if they aren't to slippery (sigh, iPhone 6 design...), I will order one ASAP. OP3/T was and is the best Android device I have ever used. So I will order OP5, but only if it doesn't feel in the hand as iPhone 6/6s/7.
I also expect that with a few updates, this device will get better and better. OnePlus did a great job on OP3/T updates, they really do listen to their customers. Vibration motor proves that, and that was my main complaint with OnePlus devices overall. Now that has been fixed, I just hope that they can improve on camera with updates as well.
