Been using it for more than a week now and I keep having this unlocking problem for like three to five times a day. Screen won't respond regardless of how hard you press your finger on the on-screen scanner area. Will have to press the power button instead to unlock using face recognition. Anyone having the same?

Try recording your fingerprint in different profiles each with a different level of pressure when you press your fingerprint.

Here is a better method. The idea is to do bootstrapping aggregation for the fingerprint using your three profiles.
Delete all your fingerprint profiles.
Create your first profile: this must be representative your finger, so place your finger in the different positions that you normally use to unlock, and with different pressures on your screen. Now that you have set your profile 1 use it as normal.
Once the sensor starts to consistently fail ( not just one failure but a considerable amount of consecutive failures) set your profile 2 mirroring the same conditions that led to the fingerprint sensor failures.
Repeat for profile 3.
If no consistent failure is found after your second profile is done you can do an outlier profile.
Each sensor failure will normally occur when using the edges of your fingerprint. So when scanning your finger for profile 3 use only the edges of your finger to create the profile.
Following this I managed almost 100% correct detection

I have had my a70 for roughly 4 months and have had various software updates throughout that time. Each update seems to affect the fingerprint sensor. They have all improved each time, up until the last one which has made it unusable. I am now using face unlock. When I first got the phone it would constantly unlock in my pocket and call people etc. I have had many samsungs and never owned an iPhone, however this phone, apart from the battery has been abit disappointing and I'm now considering a switch. I just want a phone that works and doesn't over complicate things.

Right so after trying various different methods and also after many updates fom Samsung, the basic truth is the fingerprint scanners on the Galaxy A range are usless. I have owned many Samsung Smartphones including Flagship level phones and to be fair they are on the whole, brilliant. However as smartphones have evolved, they have all become good at what they do which has forced samsung to push their phones to the max and offer tech that basically nobody needs. Take the the s20 ultra for example, why would I need 100x zoom to take a blurry photo? When would I need to use that? This can make their phones too complex leading to issues like we have with the fingerprint sensor. After many issues with my A70 including software(whatsapp camera) and Hardware(fingerprint sensor,which is probably software aswell) and also the usual disconnect between android and samsung, I have decided to move to apple for a more simple and pure experience. I would like to leave behind the android lag which you get from samsung skins and move to a more clinical and simple, does what it says on the tin, experience. Yes I will miss the organisation of android, the more advanced features like easy to access fast charging, and obviously split screen ability etc but I think for general day to day use, an iphone will get the job done and be alot more reliable!
