In this device problem of auto data connection start, wifi automatically start, hidden application automatically install, auto balance gone so try first of intex aqua i5 mini reset or hard reset but same issue not solve this problem then i decide to flash device when i flashed device with below link firmware or tool so result problem solved all type issue but not only use this tutorial above mention problem but any try software related issue in this device then you can use this tutorial but remember first carefully all read tutorial after step by step following.
This flash file tested by me without any error working well, you can use this flash file when your device hang on logo problem, restarting problem, security lock problem, password lock problem, pattern lock problem etc software related problem and you can use this tutorial without any box and this is free for all who know about software in mobile, impotent for flashing first must check your micro usb cable if not good then you can't flash it so check micro usb cable second check your device battery that is impotent for flashing if your device battery low so stop your device between flash so this is impotent for flash, before you flash save your data like contact, photos, videos etc because this is factory flash file so you can't save after full flash so must remember all are impotent notes.
