I bought Galaxy A51 last day and just using it for 12 hours, and I found these problems.
I connected my Bluetooth headphone to the Galaxy A51 for the first time, after I playing music, the sound keeps breaking every few seconds, and after 2 minutes, it automatically disconnected. Besides, When music still playing and I try to open other applications phone slows down and again sounds streams with the stuttering.
some times screen, stop working and touch not working correctly.
Also, I have other problems. I can't use L2TP VPN connections because when connected to the VPN after 60 seconds phone crashed and restarted.
I tell this problem to the customer service, and they told me it is a common problem, and you must wait for the Samsung release update to fix this problem.
I regret buying this phone.

Update - February 12, 2020:
Hello everyone.
Eventually, after two weeks, Samsung Customer Service replaced my Phone with a new one.i would like to Describe my Experience with the new Phone.
Now I have New Galaxy A51; my Phone has Android 10Q with Build Number A515FXXU1ASKJ. My previous GALAXY A51 had updated to A515FXXU1ASL6 that had a lot of problems with Bluetooth and WiFi.Because of my experience, I stopped updating the software on the new Phone. The Phone works perfectly without any problem. Bluetooth works without stuttering and keeps connection always.WiFi works perfectly, and the Phone never freezes or lagging. But my memory usage is unusual; in the last 24 hours, my average usage of memory is 3.5GB (60% of 5.8 GB available memory).
I think GALAXY A51 problems occur in new Build Numbers (A515FXXU1ASL6 / A515FXXU1ATA4). Thus, please do not update your Phone until Samsung solves problems in new versions. Please, anybody, have Bluetooth issues; please write your 'Build Number' in comments.
For finding your 'Build Number', you should go to the address below:
Setting > About Phone > Software Information > Build Number

May sound stupid but as soon as I got my phone I noticed a pre installed rubber like screen protector on. I took off right away and installed tempered glass screen protector. Just a suggestion 😀

Phone model is a515f .. dual sim model with 4gb ram. I put on screen tempered glass screen protector, I didn't notice that rubber on my screen, was wrapped in a plastic sheath.. Screen sensitivity problem comes up suddenly .. scrolling the page strangely, also becomes more sensitive to touch, and gesture movement does not work (hidden navigation buttons) or very rarely detects movement at the bottom edge of the screen. Problem disappears after restart.

Phone Model SM-A515F
Software Version: A515FXXU1ASL6

Recently i just bought Samsung A51, it seems that whenever the auto brightness kick in, the setting is bugged, where the display will dim so low that the color of the display looked bleak. does anyone experience the same thing? or is it a defective unit?

The problem is solved if i restart the phone, but in a few hours the the display goes back to dim so low again. i've already reset the setting, and also do reset accessibility, but it doesn't seem to fix this problem. anyone have an idea to fix this? or do i need to go to the samsung service center in my town?

Need help

Hello Everyone
After I am disappointed by Samsung to solve my problem, I found that when I turn off my Wi-Fi network, Bluetooth works correctly. I want to describe why this issue happens.
Wireless interference can cause Wi-Fi and Bluetooth devices to be disconnected or perform poorly. Both Wi-Fi and Bluetooth use the 2.4 GHz band to transmit data, and because of this, Bluetooth audio skips or stutters, Device doesn't connect. To Avoid Interference, you can use the 5 GHz band instead of 2.4 GHz for Wi-Fi if your router supports both bands.
I hope Samsung finds a solution to this problem because it is annoying.
