(Update as on 21/09/23)FINAL VERDICT : VERY UNSAFE & UNRELIABLE FOR ELDERLY USERS.Reason:We experienced 3 instances of panic in last 2 months of usage, when I failed to connect with my mom in emergency situations due to this stupid device. I kept calling her, while the phone was ringing (as SILENT) right in her hand/purse but she didn't hear any ring, because the volume had reduced to zero without her knowledge. (Not every time can you feel the vibration as well, and in some cases you may intentionally keep the vibration off to extend battery life.)The stupid volume control button is extremely loose and frequently gets pressed even during normal handling of the device leading to unwanted change in volume levels. On most of such instances the user is unaware about the reduced ringtone volume, and so they don't get any notification if anyone is trying to reach them. This can prove dangerous and even fatal in emergency situations. It's a un-reliable dumb phone!!!Today, I finally decided to dump this phone for a better, safer phone option for my mother (senior citizen).********************Pros:1. Flip Design2. Large KeysCons:1. Extremely Slippery Body.Due to the smooth matte texture of the body and the curvy round edges, the device is extremely slippery with no grip at all.2. They should either make the camera "camera-worthy" or remove it entirely. It's useless in this century.3. Reading messages in this phone is very inconvenient. When you open a message, the cursor is positioned in the response field by default and not at the start of the actual message (even for a new message).So, you have to scroll all the way up to the start of the message to read it.I'm wondering, if they were actually thinking that the user will type a response without reading the message!4. To add to this, scrolling is too laggy, SMS font is not easy to read, specially for old age users.5. When you flip open / un-fold the phone, the default landing screen is the list of some frequently used options (see image attached).This same list can also be accessed by the dedicated shortcut key provided on the keypad. I wonder why this screen then, and not the Home Screen??!!6. The volume control button is just so silly. The button is so flimsy that even a slight press on it while gripping/holding/during any movement inside your pocket, the volume may get reduced to level 0. You won't even realise when your phone goes on silent mode unknowingly. And this is not at all safe, specially for old age users.Nokia may have thought that they are making it convenient for the user by making the control so smooth (no tactical feel) but it can also prove a big fail feature.7. They should atleast include 1 set of screen protectors to protect the 2 screens (made of scratch prone plastic TFT). I had to purchase the screen guards separately considering the screens' quality.8. No headphones provided.Specially when this phone's Bluetooth doesn't support bluetooth headphones (considering majority of users use wireless headphones).9. The phone's 3.5 mm jack outlet wasn't very impressive. I tested my wired headphones (SONY XB75) and at some points the connection was breaking with volume fluctuations. I had to rotate the headphones' pin to reach a stable connection.10. In Contacts, there is an option "Groups" to group your contacts (under Family, Friends, Work etc.).After saving some relevant contacts, I tried if I could group some of them but I wasn't able to use the feature because when you click on it, you can't go further/add any contact to any group. You may check the quick video (with playback speed x 2)."Groups" can be a useful feature, and could prove very convenient for quick access, specially for the old age users but the phone doesn't allow it. Not sure why!11. The "pre-historic" micro USB based phone charger.I'm surprised why they are still stuck on this port type.In the present era of environmental conscious user base and responsible manufacturing environment, where the world is swiftly and consciously moving towards universal charging options like C-type USB chargers - vintage established brands like Nokia are expected to contribute more actively with more serious intent - TO LIMIT ELECTRONIC WASTE. By still using micro USB chargers for their phones they are only adding to this global pile of e-waste.NOTE: I also found that the charger's port/pin is extremely difficult to pull out once inserted into the phone's charging slot.I wonder if this is some sort of manufacturing defect specific to my device only (will check with the brand support as well).If you are an existing user and experiencing the same issue, can you please share it here?It is a serious issue, as with that kind of forceful pulling, even with both hands you are at risk of damaging either the port or the slot.Moreover, you can imagine, how this could be a big challenge for the old age users - first while putting in that "micro" usb pin in the correct orientation and then pulling out that extremely tight port out of the slot.12. Although some users may not prefer this (due to asthetic reasons) but a tiny slot to attach a lanyard chord/wrist strap could come handy, specially when the phone's body is so slippery.
