User opinions and reviews

  • 4I (2015)

Finally Found One Pretty Okay Battery Backup Custom Rom Still Felt Not The Top Yet, Running Nougat, Gaming Performance Should Be Great I Guess!

  • 4I (2015)

Experience With This Device Is Pretty Okay! Using Stock MIUI 6! Benchmark Test: 33K Low-End In 2019 But Release As A Mid-Range In 2015. Running Flawlessly But Gaming PUBG Will Lag & Heat Abit As The Chipset Is Snapdragon 615! Other Games Not Test...

  • 4I (2015)

Use Official Rom Miui 6 & 7 (Global or China) For Better Battery. Test Most Of The Custom Rom Drain A Lot Juices Out Of My Device, Hence's For This Device I Stop Using Custom Rom & Back To Stock Feels Much Better In Battery Life.... Don't Use...
