This phone is not for you, If you are a very heavy multitasking user
> Letv Le 1S runs on custom UI known as E UI which is so heavy.
> Though it has 3 GB of RAM but you will get only 1gb of RAM free even if you kill all the apps.
> If you are using 4-5 apps simultaneously in the background then it tries to kill some of the apps due this bloated UI, which can cause some issues. for e.g. if you have opened whatsapp along with some other apps then you might not be able to get the notifications from whatsapp. Only after re opening whatsapp you can get all the notifications from it.
> Because of that heavy UI Ram management is not great so it causes lag on the device.
> Handset gets warmed after about 10-15 minutes usage while on mobile data.
> Camera performance is strictly average though it has 13MP rear shooter.
If above cons are not matters for you then definitely go for it. Built quality is awesome.
