I first using xender in 2016 and then This app was trending for file sharing but it caused to my phone hangging.
Xender is the number 2 file sahring application after shareit. My all friend using xender then If I need any kind of file from them, I need to open xender application.
Xender file transfering speed too fast through wifi but in some mobile it gated lagging, in my mobile when I transfer any kind of big file like movie, jukebox, zip then its become hang and some time after its take to stop permission after many updated this problem had fixed but bux not delete yet.
Today's day xender making his marketing plan through xender application by showing ads, game, and spin also for that many mobile can't holding that app in chipset.
My opinion : If your mobile cost price in todays day avobe 10 thousands then you want to use frequently, because todays all chipset motherboard making for best performance.
