I have been using the Samsung Galaxy S25 Ultra for several months, and I am extremely disappointed due to a serious recurring network issue and a very poor refund experience with Best Buy.
The phone randomly loses all network connectivity. When this happens:
No phone calls (incoming or outgoing)
No mobile data
No communication at all
This happens suddenly and without warning, lasts about 30 seconds to 1 minute, and then reconnects by itself. This issue has been happening repeatedly for months.
What makes this even more concerning:
I already replaced the phone once
The replacement device has the exact same issue
This clearly shows the problem is systemic, not an isolated defect
Temporary actions like waiting, toggling airplane mode, or resetting the network restore service, which strongly suggests a software or modem firmware issue, likely related to 5G/LTE network switching.
For a flagship phone at this price, losing calls and data is unacceptable.
❗ Serious Issue With Best Buy (Refund Denied)
Before purchasing the phone, a Best Buy employee told me that if I purchased a one-year membership, I would be allowed to return and receive a refund for up to two months. I relied on this information when making my purchase.
However, when I later attempted to refund the phone due to this serious defect:
Best Buy refused the refund
They denied what was previously promised
I asked to speak with a manager, but the manager also did not help
This experience was:
Misleading
Unprofessional
Extremely disappointing
I feel I was given incorrect information at the time of sale, and Best Buy failed to stand behind what their employee promised.
Final Thoughts
For a premium device:
Ongoing network failures are unacceptable
Denying a refund after providing misleading return information is wrong
I am disappointed in both Samsung for the unresolved defect
and Best Buy for the way this situation was handled.
This experience has significantly damaged my trust in both companies.
Update: I reached out 5 times, so reaching out again does not seem like a resolution.
Left bad review based on HORRIBLE experience with staff and their online ordering system. Was told to reach out via social media. Did so back in October 2025. January 2026 comes and still no response
