The J3 2016 might be one of the worst phones to have ever come out
It's so slow that an S3 is faster
The Lumia 735 and the S4 mini are also faster
Mine J3 2016 only has 8 GB of storage (3 something GB usable) and 1.5 GB of ram
Its stuck on android 5.1.1 (mine has a android 7.1.1 custom rom on it)
You can get android 10 (exynos only) on it with a custom rom
It doesn't have a magnetometer (digital compass), gyroscope or ambient light sensor
It doesn't get loud even for 2016 budget standards
The lumia 735 got windows 10 1709 (6 years of support)
The lumia 735 has Wireless (Qi) charging, NFC, gyroscope and a magnetometer
Even the S1 is a bit better than J3 2016
It's louder than the J3 2016
It does have a compass
How about custom roms
Almost all links are dead
The best one i could i have found was Pixel Experience Plus
Some sensors and the gps didn't work with lineageos
I had to flash wifi-fix.zip to get the wifi to work
Edit: apparently it has been fixed in the latest build
Edit 2: it isnt fixed
And twrp is very unresponsive
