Sample report

Nigeria usability report

This is a synthetic sample showing exactly what a buyer receives after a study: device-stamped session evidence, findings with steps to reproduce, annotated frames, a scripted test-case matrix, and machine-readable exports. The app under test, DemoPay NG, is fictional. All tester references are anonymised and no real client data appears on this page. Real deliverables add full screen recordings and original screenshots.

Key finding

The transfer PIN modal (F-01) is the highest severity blocker: it reverts to empty entry while the debit is still processing, so users re-enter their PIN and risk a double debit. Together with the OTP dead end on slow 3G (F-02), the money path fails exactly where Nigerian users are least forgiving. Both failures only surface on real devices with real SIMs on congested cells.

Findings

Synthetic sample data

Each finding carries steps to reproduce, expected vs actual behaviour, the timestamp in the session recording, and a recommendation. Numbered findings tie to the evidence frames and the exports below.

F-01Transfer PIN modal reverts to empty entry while the debit is still processing

Critical
Infinix Hot 30i · Android 13 · 4G (Glo)Tester T-014207:41 into recording
Steps to reproduce
  1. Log in and open Transfer.
  2. Enter a recipient account and an amount of NGN 5,000.
  3. Tap Send and enter the transaction PIN.
  4. Wait on 4G while the signal drops to one bar.
Expected

A visible processing state stays on screen until the gateway confirms success or failure.

Actual

After about 12 seconds the PIN modal clears back to empty entry with no message. The tester re-entered the PIN, which risks a double debit on a still-processing transfer.

Recommendation

Hold the processing state, disable PIN re-entry until the gateway responds, and de-duplicate transfer requests with an idempotency key.

F-02OTP screen dead-ends when the resend countdown expires on slow 3G

High
Infinix Hot 30i · 3G (Glo, congested cell)Tester T-014204:12 into recordingReal-network finding
Steps to reproduce
  1. Sign up with a new phone number.
  2. Wait for the SMS OTP on a congested 3G cell.
  3. Let the 60 second countdown expire before the SMS arrives.
  4. Tap Resend code.
Expected

Resend requests a new OTP and restarts the countdown, or the screen offers a way back.

Actual

Resend stays disabled after the countdown hits zero and the screen has no back action. The tester recovered only by force-closing the app. An emulator on office Wi-Fi cannot reproduce this; it needs a real SIM on a congested cell.

Recommendation

Re-enable Resend the moment the countdown ends, add a back affordance, and time out gracefully with a clear retry path.

F-03KYC document upload fails silently at 90 percent when the connection drops

High
Tecno Spark 10 · Android 13 · 4G (MTN)Tester T-014411:05 into recordingReal-network finding
Steps to reproduce
  1. Open KYC and photograph the ID card.
  2. Tap Upload on 4G.
  3. Move to a weaker signal spot mid-upload, as a commuting user would.
Expected

The app reports the failed upload within seconds, keeps the captured photo, and offers retry.

Actual

The progress bar sits at 90 percent indefinitely. Leaving the screen loses the photo and KYC shows pending with nothing queued. Transfer stayed blocked for the rest of the session.

Recommendation

Upload in resumable chunks, surface failure within 30 seconds, and cache the captured image so retry does not restart from the camera.

F-04Airtime amount field rejects comma-formatted input with a generic error

Medium
Samsung Galaxy A14 · Android 14 · 4G (Airtel)Tester T-014318:47 into recording
Steps to reproduce
  1. Open Airtime.
  2. Type 5,000 with a comma, the same way the app formats money on its own receipt screens.
  3. Tap Buy airtime.
Expected

The field accepts or auto-formats the comma, or validation says exactly what to fix.

Actual

A generic toast saying something went wrong appears and nothing marks the field. Two of eight testers gave up at this step.

Recommendation

Strip separators before validation and show field-level errors instead of a global toast.

F-05Back button after logout briefly shows the cached dashboard

Low
Samsung Galaxy A14 · Android 14Tester T-014327:19 into recording
Steps to reproduce
  1. Log out from Settings.
  2. On the login screen, press the Android back button.
Expected

The session is cleared and the login screen stays in place.

Actual

The previous dashboard, including the account balance, renders for about two seconds before redirecting back to login.

Recommendation

Clear the navigation back stack on logout and gate the dashboard route on a live session check.

Evidence frames

Scripted test-case matrix

Synthetic sample

Every scripted case is run on every device in the cohort. Three of the eight devices are shown here. Transfer on the Tecno Spark 10 is blocked because KYC upload failed first (F-03).

Verbatim quotes

Pidgin quotes with English gloss, exactly as they appear in a delivered report. These examples are synthetic sample content.

“Abeg, e too dey delay when I press submit. I no know if e don go or e don jam.”
Please, it takes too long after I press submit. I do not know if it went through or got stuck.
High

During transfer submission: loading exceeded 15s with no feedback (see F-01)

“Wetin be this? Na so e dey show? Make I enter my PIN again? I no trust am.”
What is this? Is this how it shows? Should I enter my PIN again? I do not trust it.
Critical

After entering PIN on the transfer modal: screen reverted to PIN entry (see F-01)

“The font too small for my eye. I fit zoom? No wahala for WhatsApp but for this app I dey struggle.”
The font is too small for me. Can I zoom? WhatsApp is fine but I struggle with this app.
Medium

During OTP entry: font size not adjusted for the Tecno Spark 10 display

“Oya, make I transfer go another phone. My network dey fail for this app.”
I will just transfer to another phone. My network keeps failing on this app.
High

After three failed transaction retries on a congested Lagos cell (see F-02)
