Le 1s is a very good phone and I have been using it and yes the phone is very nice but yes I have felt some problems in it which are not so much major ones, when I play high end games or use high end applications it gets heat up fast.
The design and body of the phone is good and its UI is very good, the Ram in the phone is 2.1 gb available but you can restrict some background process and use 2.5 gb ram, I like its camera very much and its very good in daylight photography, the body is not that much strong but also not that much fragile, the price is very affordable as it has high end features.
For long time gaming this phone is not for you but yes for normal usgae and good battery life the phone is best for you in this range.
I recommend to buy this phone if you have budget between 10k to 14000.
Thank you!
