Signia App Not Working? Hearing Aid Bluetooth & App Fixes (Step-by-Step)
Updated: Sep 26
Quick answer: If the Signia app is not working, restart the phone, restart the hearing aids (open and close the battery doors, or place rechargeables in the charger for about 10 seconds), confirm Bluetooth and, on Android, location permission are on, then forget and re-pair. Most problems clear in minutes. If they persist, Professional Hearing Solutions in Islamabad and Rawalpindi can check firmware and settings in Connexx.

Why is my Signia app not working?
Almost every app problem comes from one of four things: a lost Bluetooth pairing, a missing phone permission, the phone's battery saver closing the app, or a hearing aid setting that was never enabled during fitting. Only a small share are true hardware faults.
Professional Hearing Solutions (PHS), an authorised Signia hearing aid dealer serving Islamabad and Rawalpindi since 1999, sees the same app questions every week: "the app cannot find my hearing aids", "calls cut out", "only the left side connects", or "it stopped working after my phone updated". The good news is that the hearing aids themselves keep working without the app. The app is a remote control and streaming companion, so an app fault rarely means your hearing aid is damaged.
The Signia app brings several tools into one place: volume and program control, sound balance, the AI-based Signia Assistant on compatible Bluetooth models, and TeleCare remote support, which must first be activated by your hearing care professional. Because it touches Bluetooth, phone permissions and the hearing aid's own programming, a fix sometimes needs the phone and sometimes needs the clinic. You can read more about what the app does on our Signia mobile app page.
What should I try first when the Signia app is not connecting?
Run the five-minute reset routine below in order. Signia's own support guidance follows the same sequence: reboot the phone, restart the hearing aids, reset the app, then reinstall.
Turn the phone off, wait about 30 seconds and turn it back on. A full restart clears Bluetooth glitches that toggling Bluetooth in the quick menu does not.
Restart both hearing aids at the same time. For battery models, open and close both battery doors (and replace a weak battery). For rechargeable models, place both aids in the charger for about 10 seconds and take them out.
Keep the hearing aids close to the phone for the next few minutes. After a restart they are in pairing mode for roughly three minutes.
Open the Signia app and wait for it to connect. Do not tap repeatedly; give it up to a minute.
If it still fails, reset the app from its settings (Settings, then App settings, then Set up the app). This does not change the programming your audiologist set in the hearing aids.
As the last home step, uninstall the app, restart the phone, reinstall it from the Play Store or App Store, and allow every permission it requests.
Resetting or reinstalling the app never erases your hearing aid prescription. Your fitting lives inside the hearing aids and is only changed in the clinic with Connexx software or through a TeleCare session you accept.
How do I fix Signia hearing aid Bluetooth pairing problems?
Delete the old pairing everywhere (phone Bluetooth list or iPhone Hearing Devices), restart the hearing aids to put them back in pairing mode, and pair again from the correct place for your phone. Pairing from the wrong menu is the most common mistake.
On Android phones (Samsung, Xiaomi, Oppo, Vivo, Infinix, Tecno and others)
Go to Settings, then Bluetooth, tap the gear next to each hearing aid and choose Forget or Unpair. Do this for both sides.
Make sure Bluetooth is on and that the Signia app has location permission. Android often needs location access for Bluetooth scanning, and without it the app can search forever.
Restart both hearing aids and place them near the phone.
Open the Signia app and follow its pairing steps. When the hearing aid names appear, tap to select and confirm pairing for each side.
Accept any second pairing request that pops up. Many Android phones ask twice, once per side.
On iPhone
Go to Settings, then Accessibility, then Hearing Devices. If your aids are listed, tap them and choose Forget This Device.
Turn Bluetooth off and on from the Settings app, not only from Control Center.
Restart both hearing aids and hold them near the iPhone.
Pair them again under Accessibility, then Hearing Devices, and accept both pairing requests (left and right).
Open the Signia app so it can find the newly paired aids.
Note that Made-for-iPhone hearing aids should be paired through Hearing Devices, not the regular Bluetooth list. On Android, direct audio streaming depends on the phone supporting the ASHA hearing aid standard or, on some newer Signia models, LE Audio. Not every Android phone includes ASHA, so a phone can control the hearing aids through the app yet still not stream calls. That is a phone limitation, not a fault.
Why does hearing aid streaming keep cutting out?
Streaming drops are usually caused by distance or body blocking, a phone in a back pocket, interference from other Bluetooth devices, low battery, or the phone's power-saving mode. Keep the phone in front of you, within a couple of metres, and switch off battery saver while streaming.
Keep the phone in front of you or on the same side. A phone in a back pocket or a handbag on the floor forces the signal through your body.
Disconnect Bluetooth devices you are not using, such as a smartwatch, car audio or earbuds.
Turn off power-saving modes during calls, because they can throttle Bluetooth.
Charge the hearing aids. Streaming uses much more power than normal listening.
Check whether it happens in only one app, such as WhatsApp calls. If normal calls are fine, update or reinstall that app.
If calls drop on every phone you try, or only one hearing aid loses the stream, the hearing aid may need a firmware update or an inspection. See our guide to hearing aid repair in Islamabad and Rawalpindi for what happens at an inspection.
Why does the app not detect my hearing aids at all?
If the app never sees the aids, check compatibility first, then permissions, then whether the aids are actually on and charged. Some older Signia models and some older phones are simply not supported by the current app.
Compatibility: the Signia app works with Bluetooth-enabled Signia models and with a minimum iOS or Android version. Older non-Bluetooth hearing aids cannot connect to it at all. Signia publishes a device compatibility checker on its website.
Permissions: on Android, open Settings, Apps, Signia, Permissions and allow Nearby devices (Bluetooth), Location and Notifications.
Power: a rechargeable aid sitting on a dead charger, or a battery aid with a flat battery, will not advertise itself. Try a fresh hearing aid battery or a known-good charging socket.
Pairing mode window: the aids are only discoverable for a few minutes after a restart. Restart them just before you pair.
Why is only one hearing aid connecting to the app?
When only one side connects, restart both aids together, check the battery or charge on the missing side, then forget and re-pair both. If one side still refuses, it usually needs a clinic check.
On Android each hearing aid appears as a separate Bluetooth device, so it is easy to accept the pairing request for one side and miss the second. Restart both aids at the same moment so they re-sync, then pair again. If one side keeps dropping after a clean re-pair, likely causes are a weak rechargeable cell, moisture, dirty charging contacts or mismatched firmware. Our audiologists read both aids in Connexx and compare them.
My phone updated and now the Signia app stopped working. What do I do?
After a phone update, permissions and battery settings are often reset and Bluetooth pairings can become stale. Update the Signia app, re-check permissions, then forget and re-pair the hearing aids.
Update the Signia app from the Play Store or App Store. App updates often follow major iOS and Android releases.
Re-check permissions. Android updates frequently switch Nearby devices or Location back to Ask or Deny.
Re-apply battery settings (see the next section) because updates can put the app back under optimisation.
Forget the hearing aids and pair again from the correct menu.
If the problem started with a new phone model, contact us. The hearing aid firmware may need an update.
What Android settings stop the Signia app from working?
Aggressive battery optimisation is the biggest culprit on Android, especially on Xiaomi, Oppo, Vivo, Realme, Infinix and Tecno phones common in Pakistan. Exempt the Signia app from battery optimisation and allow it to run in the background.
Battery: Settings, Apps, Signia, Battery, set to Unrestricted or No restrictions.
Autostart: on Xiaomi and some Chinese-brand phones, enable Autostart for the Signia app in the security or phone manager app.
Recent apps lock: lock the Signia app in the recent apps screen so the cleaner does not close it.
Cache: if the app freezes, Settings, Apps, Signia, Storage, Clear cache. Avoid Clear data unless you are ready to set the app up again.
Android vs iPhone: where to look
Issue | Android | iPhone |
Where to pair | Signia app pairing flow or Bluetooth list | Settings, Accessibility, Hearing Devices |
Direct call and music streaming | Needs ASHA (or LE Audio on some models); varies by phone | Made-for-iPhone streaming on compatible Signia models |
Main cause of drops | Battery optimisation and app killers | Stale pairing after iOS updates |
Permissions to check | Nearby devices, Location, Notifications | Bluetooth and Notifications |
Last resort | Clear cache, reinstall app | Forget device, reset network settings |
Can load-shedding, dust or humidity affect my rechargeable Signia and the app?
Yes, indirectly. If the aids did not charge fully overnight because of load-shedding, they may drop Bluetooth early in the day, and dust or sweat on the charging contacts can stop charging completely.
Plug the charger into a UPS-backed or inverter socket so an overnight power cut does not leave you with half-charged aids.
Carry a power bank with a USB cable in summer. Many Signia chargers run from a standard USB supply.
Wipe the charging contacts and the charger wells with a dry, soft cloth every few days. Dust in Islamabad and Rawalpindi builds up quickly.
In the monsoon and humid months, store battery models in a drying box overnight and never leave aids in a hot car.
Avoid cheap, unbranded wall adapters during voltage fluctuation. Use the supplied adapter or a good-quality one.
Rechargeable models such as the Signia Pure Charge&Go are very reliable when charged properly. If charge time or battery life drops sharply, bring the aids in for a check rather than living with it.
Which problems are not app problems at all?
No sound, weak sound, whistling and muffled sound usually come from wax, moisture, batteries or fit, not the app. Check these before blaming Bluetooth.
Common Signia hearing aid problems and home checks
Problem | Likely cause | Home check | Clinic needed? |
No sound | Flat battery, blocked wax guard, aid switched off | New battery or full charge, change wax guard | If still silent after both |
Weak sound | Wax in the receiver, low charge, wrong program | Change wax guard, charge, select the main program | If it stays weak |
Whistling (feedback) | Loose fit, ear wax in the canal, damaged dome | Reinsert carefully, replace dome | If it persists, fit or mould may need attention |
Muffled sound | Moisture or blocked microphone port | Dry overnight, brush the microphone openings | If muffled after drying and cleaning |
Sound cuts in and out | Dirty battery contacts, moisture | Clean contacts, fresh battery | If cutting continues |
Distorted sound | Damaged receiver or wire | Fresh battery test | Yes, needs inspection |
Weekly care matters: change the wax guard, brush the microphone openings, and keep a drying box for humid weeks. For faults that home care cannot fix, our hearing aid repair service handles all major brands, with genuine Connexx programming for Signia.
When should I bring my Signia hearing aids to PHS for Connexx reprogramming?
Bring them in when home fixes fail, when features are missing from the app, when a firmware update is needed, or when your hearing has changed. These are clinic jobs done in genuine Signia Connexx software.
Connexx is the manufacturer's fitting software. In the clinic, our audiologists connect your hearing aids, read their status, update firmware where appropriate, enable or adjust programs and streaming settings, and re-match the output to your latest audiogram. This is very different from a shop that only sells boxes. Learn more on our hearing aid programming page.
The app shows a program or control you were told about, but it does nothing or is missing.
The app repeatedly asks for a hearing aid update, or streaming fails on every phone you try.
One side never pairs even after a clean reset.
You want TeleCare remote support activated so small adjustments can be made while you are at home or travelling.
Speech still sounds unclear even though the app is working. That is a fitting issue, and fine-tuning or an updated hearing assessment is the answer.
PHS has two clinics: the Islamabad flagship at Office B-9 Basement, Muhammad Gulistan Khan House 82 East, adjacent to Tehzeeb Bakers, Fazl-ul-Haq Road, Blue Area, and the Rawalpindi branch at Office 5 & 6, Ground Floor, Siraj Plaza, Saidpur Road. Both are open Monday to Saturday, 10:00 AM to 7:00 PM. Directions are on the Islamabad branch page and the Rawalpindi branch page. Patients rate us with 400+ Google reviews with a 4.9-star average.
Bring your phone, your charger and both hearing aids, even if only one is misbehaving, so we can pair and test everything together.
Is the app problem a sign I should upgrade my hearing aids?
Not usually. Most app problems are fixable. Upgrading makes sense when your aids are old, non-Bluetooth, out of warranty with repeated faults, or no longer match your hearing.
German-original Signia devices typically last 6 to 10 years and carry the full manufacturer warranty managed by PHS. Copies do not receive genuine firmware or reliable app support, which is one reason app troubles are more common with them. If you are comparing new models, the Signia hearing aid price guide lists current models and prices, and our Signia hearing aids page explains the families.
Frequently Asked Questions
Why does the Signia app keep disconnecting on my Android phone?
The most common reason is battery optimisation closing the app in the background, especially on Xiaomi, Oppo, Vivo, Infinix and Tecno phones. Set the Signia app battery usage to Unrestricted, enable Autostart where offered, and lock it in recent apps. Also confirm Nearby devices and Location permissions are allowed, because Android updates often reset them.
Do I need the Signia app for my hearing aids to work?
No. Your hearing aids work fully without the app because your prescription is stored inside them. The app adds convenience: volume and program control, sound balance, the Signia Assistant on compatible models, and TeleCare remote support if your clinic activates it. If the app fails, you can still hear normally with the aids.
Will reinstalling the Signia app delete my hearing aid settings?
No. Reinstalling or resetting the app does not change the fitting programmed into your hearing aids. It only clears app preferences, so you pair again and set up the app afresh. Your audiologist's settings can only be changed in the clinic with Connexx software or through a TeleCare session you approve.
Why can I use the app but not stream calls on my Android phone?
Controlling the hearing aids through the app uses low-energy Bluetooth, which most phones support. Direct streaming of calls and music needs the phone to support the ASHA hearing aid standard, or LE Audio on some newer Signia models. Not every Android phone includes ASHA, so control can work while streaming does not.
Signia app mera hearing aid nahi dhoond raha, kya karun?
Pehle phone restart karein, phir dono hearing aids restart karein (battery door khol kar band karein, ya rechargeable ko 10 second charger mein rakhein). Bluetooth aur Android par Location permission on karein, purani pairing forget karke dobara pair karein. Phir bhi masla ho to 0332-5014111 par call karein ya clinic aa jayein.
Can PHS fix my Signia app problem remotely?
Many app issues can be talked through on a phone or WhatsApp call to 0332-5014111. Signia TeleCare also allows remote fine-tuning once your hearing care professional activates it. Firmware updates, missing features and hardware faults, however, need the hearing aids connected to Connexx in our Islamabad or Rawalpindi clinic.
