Review of HiOS: How well does TECNO’s custom user interface work?

Posted by

It is not exactly news anymore that TECNO has launched a custom user interface to distinguish their smartphones from other generic Android phones out there. The question is whether HiOS delivers more value to the user than vanilla Android user interface does. It has been my experience that even the most functional custom UIs also have issues that users have to deal with. Will HiOS be any different? I have had a unit of the J8 (the first phone to run HiOS out of the box) with me for a few weeks now, and I have found out. Come with me.

HiOS Themes & Fonts

I love that HiOS lets users apply themes to their device to give it the look and feel of their choice. Of all the available themes, I fell in love with the N Family because the design scheme is based on an old love of mine, Symbian OS. Feel free to pick yours.

HiOS also lets you pick a default font for the device from a range of available fonts. Personally, I am very fine with the preset font.

HiOS Web Browser

There is a new default browser that comes with HiOS, and it isn’t what it used to be on older TECNO phones. It is redesigned and built on Chromium engine. Technicalities aside, it looks clean but fails me in a key area.

After loading a webpage in the browser, tap the address bar to edit the website address there, and it clears EVERYTHING there, leaving you a blank address bar. You cannot edit text in there. You cannot copy or paste. You can only clear it and then type all over from scratch. TECNO, that’s a no no. Very poor. Please fix this like yesterday. Update: TECNO Mobile has since fixed this in subsequent releases of HiOS. You can now tap on the address bar to edit the website address there without it clearing everything. Yay!

HiOS web browser

The user interface of the browser is good. I like that most controls are placed at the bottom of the screen within easy reach of fingers. It would be nice if TECNO would move the address bar, search button and refresh button down too.

Hi Manager

Hi Manager let’s he user cleanup and free space on the device to improve performance. You can also choose what apps auto-start when your phone boots.

Number Blocking

HiOS call block
I was glad to see that HiOS comes with a feature that lets you block pesky numbers that call or SMS you. I rejoiced too soon though, as the implementation wasn’t as user friendly as I would have loved. You cannot block an unknown number. You have to save the number first to be able to block it. Which is odd for some scenarios. If a spam number calls me, I don’t want to save it. I just want to block it and move on.

Hi Message

The HiOS messaging app brings a few nifty features. You can pin a message to the top of your SMS list. Nice for messages you want to remember. You can also move a message to a “Notice” timeline, as well as determine how you want your messages displayed – according to dates or names.

Update: Hi Message also allows you to schedule messages. The function is hidden deep in the message composition menu that it took some digging around to find it. While I feel great about being able to schedule outgoing messages, I do think that hiding it away like that is a bad idea.

Other Bits and Pieces

HiOS includes a feature that gives you the option to display in the notification bar at the top of the screen your current internet data speed. That is similar to what obtains on Xiaomi’s MIUI. I like it. I can tell when my connection is performing optimally and when it isn’t.

A Bandwidth Manager let’s you set a limit on the amount of data you use on the device periodically.

HiOS Performance

On the performance end, HiOS appears to perform well, but there is one place where you will see a significant amount of lag – when you swipe down to use the drop-down menu. There is a significant pause between when you swipe down and the menu actually responds and drops down. We ran comparisons with other devices and it was quite glaring – and grating.


TECNO’s HiOS looks good and is simple enough for most users. While it adds extra functionality here and there, there isn’t anything groundbreaking in it, but it gives TECNO phones a distinct look. It also needs touching up here and there. The browser address bar issue, in particular, is a horrible one. Power web users will groan and curse over that. Whenever TECNO fixes that and a few other minor issues, HiOS will be close to perfect.


  1. Eem, I didn’t think Tecno was for the power user – least of all, users of the new J8.

    Anyway, I hear is Camon C8 users should be expecting the update some time next month so….??

  2. Noni, now that you mention it, spot on. TECNO smartphones are clearly not for power users. Still, that issue with the browser is really bad.

  3. Hi Mr. Mo,
    Thank you for this article . I am one of the software product manager of HiOS. About th e HiOS Performance part ,will you take a screenshot and send me an email ?

  4. Power users!

    I think the BOOM J8 is here to solve all those power issues with the optimization the HiOS is bringing to their phones

  5. IMr Mo

    You failed to mention that the Hi Message can help people actually schedule messages

    That’s a massive one in messaging

  6. Also, you need not save a number before you block them as far as I have seen

    I have blocked some Airtel spam calls and I did not save them

  7. OnyeAraNdilgbo, please state the steps for blocking a number without first saving it. We have tried to do it several times here without success.

  8. Dear Mister Mo, the only devices that I use the built-in browser with are BlackBerry and iOS. On Android it’s either Dolphin or Opera.

    I can live without the disappointment.

  9. Ogohidaniel,

    I stated a problem with number blocking as implemented in HiOS. It is unintuitive. It requires me to save a number first in the phone menu before I can block it. OnyeAraNdilgbo says he is able to block numbers without saving them, so I have asked for steps to replicate it. So, far, I do not see how to block a number without first saving it.

    A number that I want to block calls me. I open the phone menu and want to block it from there. No show. If I have to first open another app e.g. Hi Manager, that is even more unintuiitive. The blocking should be possible right there in the phone menu/app, and without me saving the number.

    Kindly assist with steps to block unwanted numbers from inside the phone menu if you have them.

  10. Honestly Hi Manager is just the most irritating app ever. It keeps suggesting I freeze apps that I frequently use, an alert I can’t disable. Worse, I now have so many apps it thinks should be frozen that it fills the whole screen with a notification which can’t be dismissed and which doesn’t contain the freeze or cancel options, forcing you to restart your phone in order to use it again. I hate it and wish I could uninstall or at least disable it.
